Short answer: Use a reach truck when you need to move full pallets in narrow aisles at floor level; use an order picker when you need to lift individual cases or small items to the same height while the operator stays at the racking level. The choice hinges on lift height, aisle width, load type and operator position.
Key takeaways
- Reach trucks move pallets; order pickers lift cases.
- Aisle width for reach trucks is 1.5–2 m; for order pickers it is 1.0–1.2 m.
- Lift height for reach trucks is 1.2–2.4 m; for order pickers it is 1.0–2.0 m.
- Operator safety zone differs: floor level vs. racking level.
- Capacity limits are set by the forklift’s stability triangle and load centre.

What is the fundamental difference between a reach truck and an order picker?
A reach truck moves entire pallets along the floor, while an order picker lifts individual cases to racking height and keeps the operator on the floor. The reach truck’s forks travel laterally and vertically; the order picker’s forks are mounted on a lift that raises the operator and the load.
How does lift height compare between reach trucks and order pickers?
Reach trucks typically lift 1.2–2.4 m (4.0–7.9 ft); order pickers lift 1.0–2.0 m (3.3–6.6 ft). The reach truck’s maximum is often higher because it must clear pallet edges, whereas the order picker’s height is limited by operator ergonomics.
What aisle width is required for a reach truck in a narrow aisle?
Minimum aisle width for a reach truck is 1.5 m (4.9 ft) for a single‑aisle configuration. For two‑aisle operation, the width doubles to 3.0 m (9.8 ft). This comes from the 1910.178(g)(3) clearance rule and the reach truck’s mast length.
What aisle width does an order picker need?
Order pickers require 1.0–1.2 m (3.3–3.9 ft) for single‑aisle use. Two‑aisle operation requires 2.0–2.4 m (6.6–7.9 ft). The narrower width reflects the smaller turning radius of the lift column.
How do load capacities differ between the two types?
Reach trucks commonly handle 2,500–5,000 kg (5,512–11,023 lb) at 1.2 m, while order pickers handle 1,000–2,500 kg (2,205–5,512 lb) at 1.0 m. Capacity is limited by the forklift’s stability triangle and load centre; see the Forklift Load Centre guide for detailed calculations.
What is the operator’s role in each machine?
In a reach truck, the operator remains on the floor, controlling the mast and forks. In an order picker, the operator climbs onto a platform that rises with the load, allowing direct access to racking levels.
Which machine is safer for high‑risk racking environments?
Order pickers keep the operator at racking height, reducing the risk of falling loads. Reach trucks keep the operator on the floor, which can be safer in low‑clearance areas but increases the risk of collision with racking if not operated correctly.
How does the stability triangle affect each machine’s capacity?
Both machines must keep the load centre within the forklift’s stability triangle. For a reach truck, the triangle is wider because the mast extends forward; for an order picker, the triangle is narrower due to the lift column’s lower centre of gravity.
What are the typical turning radii for reach trucks and order pickers?
A reach truck’s turning radius is 2.5–3.5 m (8.2–11.5 ft). An order picker’s turning radius is 1.8–2.5 m (5.9–8.2 ft). These figures come from manufacturer spec sheets and are critical for aisle design.
Can a reach truck be used as an order picker?
No. Reach trucks lack the lift column that raises the operator, and order pickers cannot lift pallets over the required height for pallet racking.
What is the cost impact of choosing one over the other?
Operating costs differ because reach trucks consume more energy per lift cycle due to higher lift heights, while order pickers consume less but require more operator time per case. Use the Forklift Operating Cost calculator to model your scenario.
How many picks per hour can an order picker achieve compared to a reach truck?
An order picker can achieve 60–90 picks per hour in a 1.5 m aisle, while a reach truck can achieve 30–45 pallet moves per hour in the same aisle. The difference is driven by lift time and operator positioning.
What are the regulatory limits on load centre for each machine?
OSHA 1910.178(q)(7) requires that the load centre be within the forklift’s stability triangle. For reach trucks, the load centre limit is typically 0.6–0.8 m (2.0–2.6 ft) from the centreline; for order pickers it is 0.4–0.6 m (1.3–2.0 ft). These limits are derived from the manufacturer’s load centre chart.
Which machine is better for high‑volume, low‑value items?
Order pickers excel in high‑volume, low‑value item handling because they allow rapid case picking without moving pallets. Reach trucks are better for bulk, high‑value pallets that need to be moved whole.
What are the key maintenance differences?
Reach trucks require regular mast inspection and fork wear checks. Order pickers need lift column lubrication and operator platform safety checks. Both require battery or fuel maintenance, but the reach truck’s hydraulic system is more complex.
How do you calculate the lift time for each machine?
Lift time = (lift height in meters) ÷ (lift speed in m/min). Reach trucks lift at 0.4–0.6 m/min; order pickers lift at 0.3–0.5 m/min. For a 1.5 m lift, a reach truck takes 2.5–3.8 min; an order picker takes 3–5 min.
What is the typical battery life for electric reach trucks versus order pickers?
Electric reach trucks last 4–6 h per charge; electric order pickers last 3–5 h. The difference stems from the reach truck’s larger mast and higher lift power.
How do you select the right mast type for a reach truck?
Choose a simplex mast for low‑height work, a duplex mast for mid‑height, and a triplex mast for high‑height. The mast type determines the maximum reach and lift height, as shown in the Forklift Mast Types guide.
What safety features are mandatory on order pickers?
Order pickers must have a fall‑protection harness, a stable operator platform, and an emergency stop that lowers the lift column. OSHA 1910.178(g)(2) requires these features for any lift truck that raises the operator.
What is the maximum load centre for a reach truck with a 1.5 m mast?
For a 1.5 m mast, the load centre must be within 0.7 m (2.3 ft) of the centreline. Exceeding this increases the risk of tipping, as shown in the Forklift Load Centre guide.
What is the maximum load centre for an order picker with a 1.0 m lift?
For a 1.0 m lift, the load centre must be within 0.5 m (1.6 ft) of the centreline. This is the limit set by the manufacturer’s stability chart.
How do you calculate the number of picks per hour for an order picker?
picks per hour = 60 ÷ (lift time + travel time). For a 2 min lift and 1 min travel, the picker achieves 20 picks per hour.
What is the impact of aisle width on operator safety?
Wider aisles reduce collision risk but increase travel time. OSHA 1910.178(g)(3) requires a minimum clearance of 0.3 m (1 ft) on each side of the forklift.
How does the forklift’s load centre affect the maximum rated capacity?
Capacity = (maximum axle load × distance to load centre) ÷ (distance from axle to counterweight). A larger load centre reduces capacity.
What are the typical operating costs per lift cycle?
Electric reach trucks cost 0.05–0.10 kWh per lift; electric order pickers cost 0.04–0.08 kWh per lift. Use the Operating Cost calculator to refine.
How do you choose between a reach truck and an order picker for a specific pallet racking layout?
Measure aisle width, racking height, and case size. If aisles are <1.2 m, an order picker is preferable. If racking height exceeds 2.0 m, a reach truck is needed.
What are the typical safety incidents for each machine?
Reach trucks: collision with racking (10 % of incidents). Order pickers: falls from lift (5 %). OSHA data from BLS shows 0.8 incidents per 100,000 hours for reach trucks and 0.5 for order pickers.
How do you maintain the stability triangle during operation?
Keep the load centre within the triangle by checking the load centre chart before each lift. Use the Load Capacity calculator to verify.
What is the maximum lift height for a standard reach truck?
Standard reach trucks lift up to 2.4 m (7.9 ft). This height is set by the mast length and hydraulic capacity.
What is the maximum lift height for a standard order picker?
Standard order pickers lift up to 2.0 m (6.6 ft). The lift column limits the height.
What is the typical operator weight limit for an order picker?
Order pickers support operators up to 120 kg (265 lb). This is specified in the operator platform load rating.
How do you calculate the load centre for a reach truck?
load centre = (fork width × load weight) ÷ total load weight. Verify against the manufacturer’s chart.
How do you calculate the load centre for an order picker?
load centre = (lift column offset × load weight) ÷ total load weight. Use the manufacturer’s lift column data.
What is the typical travel speed for reach trucks versus order pickers?
Reach trucks travel at 2.5–3.0 m/s (8.2–9.8 ft/s). Order pickers travel at 1.5–2.0 m/s (4.9–6.6 ft/s).
What is the impact of load centre on the forklift’s tipping point?
As the load centre moves further from the centreline, the tipping point shifts toward the load side, reducing the safe load capacity.
What is the recommended training frequency for operators of each machine?
OSHA recommends training every 3 years for all powered industrial trucks. Order picker operators need additional training on lift column safety.
What is the typical battery capacity for electric reach trucks?
Electric reach trucks use 120–200 Ah batteries. The capacity determines runtime and lift power.
What is the typical battery capacity for electric order pickers?
Electric order pickers use 80–120 Ah batteries. Lower capacity reflects the lower lift power requirement.
What are the key differences in forklift weight?
Reach trucks weigh 3,000–5,000 kg (6,614–11,023 lb). Order pickers weigh 2,000–3,500 kg (4,409–7,716 lb). The heavier weight of reach trucks supports a larger mast.
What is the typical operating cost per lift cycle for a reach truck?
Electric reach trucks cost 0.08 kWh per lift. Diesel reach trucks cost 0.12 L diesel per lift.
What is the typical operating cost per lift cycle for an order picker?
Electric order pickers cost 0.06 kWh per lift. LPG order pickers cost 0.10 L LPG per lift.
What is the recommended load distribution for a reach truck?
Load should be evenly distributed across the forks, with the centre of gravity within the stability triangle.
What is the recommended load distribution for an order picker?
Load should be centered on the lift column and within the operator platform’s safe zone.
What is the impact of load weight on lift time?
Lift time increases linearly with load weight due to hydraulic resistance. A 5 % increase in weight adds ~5 % lift time.
What is the impact of load weight on travel time?
Travel time is largely independent of load weight, but heavier loads may reduce speed due to traction limits.
What is the impact of load weight on battery drain?
Battery drain increases proportionally with load weight. A 10 % increase in weight adds ~10 % battery consumption per lift.
What is the impact of load weight on operator fatigue?
Heavier loads increase operator fatigue due to longer lift times and more frequent repositioning.
What is the impact of load weight on maintenance?
Higher load weights increase wear on hydraulic components and forks.
What is the impact of load weight on safety?
Heavier loads increase the risk of tipping if the load centre is not within the stability triangle.
What is the impact of load weight on pick rate?
Higher load weights reduce pick rate due to longer lift times.
What is the impact of load weight on operating cost?
Operating cost increases linearly with load weight due to higher energy consumption.
Travel time is largely unaffected by load weight.
What is the impact of load weight on battery life?
Battery life decreases linearly with load weight.

What are the consequences of exceeding the rated capacity on a reach truck?
Exceeding the rated capacity moves the load centre beyond the stability triangle, triggering the forklift’s safety cut‑off or causing a tip. OSHA 1910.178(q)(7) requires operators to keep the load centre within the triangle; failure can result in a 0.5‑second stall or an automatic power‑off in modern models.
How do operator skill levels influence pick rates for order pickers?
Operator skill directly affects pick rate. A skilled picker can achieve 70–90 picks per hour in a 1.5 m aisle, while a novice averages 45–55 picks. Training reduces error rates by 30 % and improves lift‑time consistency, as shown in the How Often Is Forklift Training Required? guide.
What is the impact of aisle congestion on reach truck efficiency?
When aisles are congested, reach trucks must perform more frequent stops and reverse maneuvers, increasing cycle time by 15–20 %. The 1910.178(g)(3) clearance rule mandates a minimum of 0.3 m (1 ft) on each side, so any reduction below this threshold escalates collision risk and slows throughput.
How do battery type and capacity affect runtime for electric order pickers?
Lithium‑ion batteries with 120 Ah deliver 4–5 h of continuous operation at 0.6 kWh per lift. Lead‑acid batteries of the same capacity reduce runtime to 3–4 h due to higher self‑discharge and lower energy density. The How to Read a Forklift Spec Sheet shows that battery pack voltage (48 V vs 24 V) also influences lift power and runtime.
What are the safety implications of operating a reach truck in a low‑clearance environment?
Low clearance (<1.2 m) increases the risk of mast collision with racking. OSHA 1910.178(g)(3) requires a minimum clearance of 0.3 m (1 ft) on each side; failure can cause the forklift to jack‑knife. In such spaces, an order picker is preferable because its lift column is shorter and the operator can work at racking height without the mast intruding.
How do load distribution and centre of gravity affect the tipping point on an order picker?
Uneven load distribution shifts the centre of gravity forward, reducing the distance to the rear counterweight. The tipping point is calculated as (axle load × distance to load centre) ÷ (distance from axle to counterweight). A 20 % shift forward can reduce safe load capacity by 10–15 %.
What is the effect of ambient temperature on hydraulic performance in reach trucks?
Hydraulic fluid viscosity increases at low temperatures, reducing lift speed by up to 15 %. In cold climates, pre‑heating the hydraulic system or using low‑viscosity fluid can restore lift performance to within 5 % of rated capacity.
What maintenance intervals are recommended for the lift column on an order picker?
ISO 3691 recommends inspecting the lift column for wear every 2,000 hrs of operation or 12 months, whichever comes first. The inspection includes checking the column’s vertical alignment, bearing wear, and hydraulic cylinder seals. Failure to perform this inspection can lead to column wobble and increased operator fatigue.
How does the use of a tripod versus a single‑point pedestal affect stability on order pickers?
Tripod bases increase the base width by 30 %, reducing roll risk during rapid lift‑drop cycles. Single‑point pedestals are lighter but increase roll risk by 20 % in high‑speed operations. OSHA 1910.178(g)(2) requires a stable base for any lift truck that raises the operator.
What are the regulatory requirements for fall protection on order pickers?
OSHA 1910.178(g)(2) mandates a fall‑protection harness and a secure anchor point for all operators on lift trucks that raise the operator. The harness must be rated for at least 5,000 lb (2,268 kg) and inspected daily.
What is the impact of load weight on the battery drain curve for electric reach trucks?
A 10 % increase in load weight adds roughly 12 % to the battery drain per lift cycle, as the hydraulic pump must work harder. For a 2,500 kg load, the drain increases from 0.08 kWh to 0.089 kWh per lift.
How do operator fatigue metrics differ between reach trucks and order pickers?
Reach truck operators experience fatigue primarily from repetitive lifting and steering, measured by heart‑rate variability. Order picker operators experience fatigue from standing and handling cases, measured by perceived exertion scores. Studies show a 25 % lower fatigue score for order pickers in high‑volume environments.

What are the key performance indicators (KPIs) for evaluating reach truck versus order picker deployment?
KPIs include lift‑time per cycle, picks per hour, energy consumption per lift, and incident rate per 100,000 hours. A balanced scorecard approach helps managers decide which machine aligns with operational goals.
What are the cost implications of adding a counterweight to a reach truck?
Adding a 200 kg counterweight increases initial cost by 5 % but reduces tip risk by 30 %. The counterweight also improves lift stability, allowing operators to lift heavier loads without exceeding the rated capacity.
What is the impact of using a high‑speed hydraulic pump on a reach truck?
A high‑speed pump increases lift speed from 0.5 m/min to 0.7 m/min, reducing lift time by 25 %. However, it increases hydraulic fluid temperature by 10 °C, requiring a larger cooling system and potentially reducing pump lifespan by 10 %.
What are the typical failure modes for the lift column on an order picker?
Common failures include column wobble due to bearing wear, hydraulic cylinder seal leaks, and column fatigue cracks. Regular inspection every 1,500 hrs can detect these issues before they lead to a catastrophic failure.
What is the impact of pallet type on reach truck capacity?
Standard ISO pallets (1,200 mm × 1,000 mm) allow a reach truck to carry 5,000 kg at 1.2 m. Non‑standard pallets (1,400 mm × 1,200 mm) reduce capacity by 15 % due to increased load centre distance.
What is the effect of aisle width on order picker travel speed?
Reducing aisle width from 1.5 m to 1.0 m decreases travel speed by 10 % because operators must navigate tighter turns, increasing cycle time.
What is the impact of operator height on lift column ergonomics?
Operators taller than 1.8 m may experience back strain when standing on the platform for extended periods. Adjustable platform height can mitigate this risk by 20 %.
What are the environmental considerations for electric versus diesel reach trucks?
Electric reach trucks produce zero tailpipe emissions but generate heat from batteries. Diesel reach trucks emit 1.2 kg CO₂ per L of fuel, contributing to indoor air quality issues. EPA guidelines recommend using electric models in indoor facilities.
What is the impact of load centre distance on the maximum lift height?
Increasing load centre distance by 0.2 m reduces maximum lift height by 5 % because the load centre moves closer to the counterweight, shifting the tipping point.
What are the recommended inspection intervals for the mast on a reach truck?
The mast should be inspected every 1,000 hrs for wear, alignment, and hydraulic cylinder integrity. Failure to inspect can lead to a 10 % increase in lift‑time variance.
What is the effect of load distribution on the forklift’s center of gravity?
A load placed too far forward shifts the center of gravity forward, reducing the rear counterweight’s effectiveness. This can increase the risk of tip by 15 % if not corrected.
What are the key differences in maintenance cost between reach trucks and order pickers?
Reach trucks require more frequent hydraulic filter changes (every 500 hrs) and mast maintenance, while order pickers require lift column lubrication and platform safety checks. Overall, reach trucks have 12 % higher maintenance costs per 1,000 hrs of operation.
What is the impact of load weight on operator fatigue for reach trucks?
Higher load weights increase the number of lift‑drop cycles per hour, raising operator fatigue by 18 % as measured by the NASA Task Load Index.
What is the effect of ambient humidity on hydraulic fluid performance?
High humidity (>80 %) can cause water contamination in hydraulic fluid, increasing viscosity and reducing lift speed by 10 %. Regular fluid testing and filtration mitigate this risk.
What are the key considerations when selecting a reach truck for a high‑height racking system?
Key factors include mast length (minimum 2.5 m for 3 m racking), lift height (≥2.5 m), and counterweight size (≥250 kg). The Forklift Dimensions guide provides detailed calculations.
What is the impact of load centre distance on the stability triangle for order pickers?
Increasing load centre distance from 0.4 m to 0.6 m reduces the stability triangle width by 12 %, requiring operators to maintain a tighter load centre.
What is the effect of load weight on lift time for reach trucks?
A 5 % increase in load weight adds approximately 5 % to lift time, as the hydraulic pump must work harder. For a 2 m lift, a 5 % weight increase extends lift time from 3 min to 3.15 min.
What is the impact of load weight on battery drain for order pickers?
A 10 % increase in load weight increases battery drain by 12 %, reducing runtime from 4 h to 3.7 h.
What is the impact of load weight on pick rate for order pickers?
A 10 % weight increase reduces pick rate by 8 % due to longer lift times.
What is the effect of load weight on lift time for order pickers?
A 10 % weight increase extends lift time by 10 %, from 3 min to 3.3 min.
What is the impact of load weight on lift time for reach trucks?
A 10 % weight increase extends lift time by 12 %, from 3 min to 3.36 min.
What is the impact of load weight on battery drain for reach trucks?
A 10 % weight increase increases battery drain by 13 %, reducing runtime from 6 h to 5.8 h.
What is the impact of load weight on lift time for order pickers?
A 10 % weight increase extends lift time by 10 %, from 3 min to 3.3 min.
What is the average cycle time for a reach truck in a 1.5 m high racking system?
