Freight Elevators for Forklifts: Load, Wheel Loads and Clearance Checklist
Editorial update, October 9, 2026: additional procurement evidence and tender-scope checks. Worked figures remain hypothetical; neither the example nor this article establishes a JAFITA product rating, engineering approval or permission for forklift use.

In this guide
Start with three questions: What travels in the elevator? How does it enter? Can the approved elevator accommodate that loading method? A capacity figure answers only part of the problem.
This guide helps warehouse managers, contractors and procurement teams prepare a useful specification. Final capacity, floor-loading approval and permission for people to travel must be confirmed for the selected equipment and destination requirements.
1. Define the loading method before requesting a capacity
Two sites moving identical pallets can need different elevator arrangements. At one site, a forklift stays on the landing and transfers goods to a pallet truck. At another, the loaded forklift travels between floors.
| Loading arrangement | What the project must establish | Main procurement question |
|---|---|---|
| Forklift stays outside the car | Transfer method, pallet handling and whether any wheels cross the sill | Can the approved loading arrangement handle the transfer at the entrance? |
| Forklift enters to load, then leaves | Temporary truck-and-load position, wheel reactions and unloading sequence | Is truck entry approved during loading, even though the truck does not travel? |
| Loaded forklift travels in the car | Combined moving mass, axle loads, truck envelope and permitted occupants | Is the elevator approved for this complete operating case? |
| Handling equipment changes between shifts | Every truck and attachment likely to be used | Which combination controls the design? |
Do not describe all four as “pallet loading.” Give each operating case a name and show it on a simple plan. Where different loading classifications apply, ask the elevator supplier to identify the applicable classification and any restrictions in the proposal.
JAFITA’s heavy-duty elevator page covers concentrated loads and industrial operating conditions. The worksheet below turns that broader discussion into information a buyer can collect.
2. Calculate the complete transported mass
For a truck that travels with its load, record the configured truck mass, the actual payload, the operator if permitted, and anything else carried. Include batteries and attachments in the truck mass where the manufacturer’s figure includes them; add them separately only when it does not.
Do not confuse the forklift’s lifting capacity with its own weight. Record the truck’s service mass from the manufacturer’s documentation for the actual battery and attachment configuration. Michigan’s Part 21 rules define truck capacity and address nameplates and modifications. See Michigan Part 21: capacity and equipment requirements.
Worked example: a mass check, not an elevator specification
The following figures are hypothetical and are not JAFITA product ratings.
| Item travelling in the elevator | Illustrative mass |
|---|---|
| Forklift in its working configuration, including battery and attachment | 3,100 kg |
| Goods and pallet | 1,500 kg |
| Operator, where permitted | 90 kg |
| Additional carried equipment | 60 kg |
| Combined transported mass | 4,750 kg |
A 4,000 kg rating would be below this example’s transported mass. A nominal 5,000 kg rating would be above it, but that fact alone would not approve the application. The floor, sill, loading classification, wheel reactions, clearances and operating method would still need review.
Do not use a generic percentage allowance to bypass those checks. Ask the designer to state the design basis and operating limits explicitly.
As a jurisdiction-specific example, Michigan’s Part 21 rules, Rule 2191, require authorized entry onto a level elevator and prohibit entry when the combined truck-and-load weight exceeds elevator capacity. This Michigan guidance is not a universal rulebook; confirm the destination requirements and the elevator supplier’s loading approval. See Michigan Part 21, Rule 2191: Entering Elevators.
3. Obtain wheel and axle information
Total mass does not explain where the load acts. The same truck can place different reactions on its axles when empty, loaded or fitted with another attachment. The entry sequence also matters: wheels cross the sill before reaching their travelling position inside the car.
Ask the truck manufacturer or responsible engineer for the relevant loaded and unloaded axle reactions. Do not divide the total mass equally by the number of wheels and treat that average as an approved wheel load.
Provide the elevator supplier with:
- The truck model, configured mass and permitted payload.
- Wheelbase, track width, wheel arrangement and tyre information.
- Loaded and unloaded axle data, where available.
- Attachment details and the specified load position.
- The truck’s intended position while travelling.
- A drawing of entry, unloading and exit at each landing.
Ask the proposal to identify how the car platform and entrance sill accommodate the submitted loading case. If a supplier requests more data, keep the unresolved field visible rather than replacing it with an estimate.
4. Measure the complete route
The useful transport envelope includes the truck, forks, load, mast, overhead guard and any protruding packaging in their intended travel condition. Installed equipment dimensions are not always the same as shipping dimensions.
Check the route in sequence:
| Location | Measurement or evidence to collect |
|---|---|
| Approach aisle | Clear width, turning layout, obstructions and traffic conflicts |
| Landing entrance | Clear opening width and height, threshold and approach alignment |
| Inside the car | Usable dimensions after protective fittings and other projections |
| Travelling position | Space for the complete truck/load envelope and permitted operator |
| Destination landing | Exit direction, turning route and space to receive the load |
An opposite-side exit may change the handling process, but it also changes the building and elevator layout. Compare a through-car arrangement with same-side entry and exit using the actual floor plans.
Do not reserve a shaft from the desired car dimensions alone. The elevator layout must also accommodate its doors, guides, drive arrangement and other equipment. JAFITA’s custom elevator guidance explains why changes in one dimension can affect several building interfaces.
5. Describe the busiest operating period
“Heavy duty” should describe an operating case, not just appear in the purchase order. Record loaded trips during the busiest hour, shift patterns, typical loading time and the consequences of an unavailable lift.
For an initial logistics discussion, separate one cycle into loading, door operation, travel, unloading and the next required movement. This is a planning breakdown, not a project-specific engineering calculation of elevator throughput. Increasing travel speed may offer little benefit if manoeuvring and loading dominate the cycle.
Also state environmental conditions such as moisture, dust, washdown exposure or outdoor landings. Ask which proposed features respond to each condition, rather than accepting an undefined “industrial package.”
6. Use a consistent RFQ checklist
Send the same information to every shortlisted supplier. Mark unknown items as “to be confirmed” and assign someone to resolve them.
When reviewing quotations, distinguish a confirmed value from an assumption. A lower price may reflect a different loading case, excluded building work or a less demanding duty specification.
Frequently asked questions
Can a forklift use any freight elevator?
No. Confirm that the selected elevator permits the truck’s loading method, wheel loads, dimensions and intended occupants. “Freight elevator” alone does not establish those conditions.
Is a capacity above the combined weight enough?
No. It addresses the total transported mass but not the distribution of load, sill conditions, route geometry or approved operation.
If the truck leaves before travel, can its weight be ignored?
Its entry still creates a loading case for the car and entrance. Tell the supplier exactly how far it enters and how goods are transferred.
What if we do not have axle-load data?
Provide the exact truck model and configuration and request the relevant data from its manufacturer. Record that the structural loading review remains open until adequate information is available.
Prepare your project enquiry
Start with the truck record, the heaviest operating case and drawings of both landings. Use JAFITA’s freight elevator page to review the product category, then send a project enquiry with the completed checklist. Ask for a configuration-specific assessment of capacity, loading method and layout before freezing the building design.
