Moving Machinery in Freight Elevators
& to Upper Floors
Direct Answer: A freight elevator move must pass three tests at once: rated capacity, car floor loading, and door opening height. Standard 4″–6″ skates can fail two of those before the doors close — point-loading the car floor and raising the machine into the door header. Machinery Sliders™ spread the load across the car floor and add just 3/8″ to 1″ of height, passing all three tests where wheeled equipment can’t. Sets of four start at $142.97.
The Elevator Sets the Rules
Three limits, not one: Moving a machine to an upper floor by freight elevator means passing three tests at once. The car’s rated capacity — the machine, the moving equipment, and the crew all count against it. The car’s floor — which takes whatever pressure your moving equipment concentrates on it. And the door opening — which, like a shipping container, is shorter than the car itself. A machine on 4″–6″ wheeled skates can fail two of those three tests before the doors even close: the wheels hammer the car floor with point loads, and the added height can put the machine into the door header.
And know the elevator’s loading class: Here’s the detail even experienced crews miss: under the elevator safety code (ASME A17.1), freight elevators are classified by how they’re loaded, not just how much they carry. A car rated for general distributed freight may not permit an industrial truck to drive in at all — even well under its capacity. Confirm the loading class with the building’s elevator service provider before planning to roll or drive anything into the car. The sill also takes concentrated stress while the machine is half in and half out, which is one more reason low, load-spreading support beats wheels at the threshold.
Why Machinery Sliders Fit Elevator Work
Kind to the car floor: Machinery Sliders spread the machine’s weight across their full face — non-point loading — so the elevator car floor sees low, distributed pressure instead of concentrated wheel loads. And the threshold — the gap and sill plate between the building floor and the car — is the classic elevator trap: a small skate wheel drops into that gap under load and the move stops right there, half in and half out. A slider’s broad face bridges the gap like a plate, carrying the load smoothly across the transition in both directions — and where the gap or the load is big enough that the elevator provider calls for a rated bridging plate, use one; the sliders glide over it the same way they glide over a dock plate.
Kind to the door header: At 3/8″ (single-direction) to 1″ (multi-directional, or effectively 1/2″ on the 4″-opening model with the leveling pad nested inside), sliders give back the inches that skates steal. A machine that clears the elevator door on the floor clears it on Machinery Sliders.
Kind to what’s upstairs: Upper floors are usually finished floors — tile, sealed concrete, wood — down corridors with thresholds and tight turns. That’s Slider territory: low, controlled, non-point-loaded, with round multi-directional sliders giving 360° control to negotiate corridor corners and walk the machine onto its final footprint.

Verify Before You Ride
The building has the numbers — get them: Before the move, confirm the elevator’s rated capacity and loading class with the building engineer or elevator service provider, and count everything against the capacity: machine, sliders, timbers, jacks, and people. Measure the actual door opening and car depth, not the nominal figures — and remember that floor protection eats clearance too: masonite or plywood down the corridor adds height under the machine just like the Sliders do, so count it in the door-header math. Book the freight elevator window with building management, and ask for the car in service mode with protective pads hung — upper-floor moves live and die by scheduling and coordination. And for heavy machines going to upper floors, ask the building engineer about the floor’s structural load rating along the travel path and at the machine’s final position; no moving method changes what a building floor can carry. A machine move upstairs is a partnership with the building — the crews that treat it that way get invited back.
Travel light: A whole slider kit weighs less than one steel dolly and rides up in a milk crate — no wrestling 120 lb skates through a lobby. Sets of four start at $142.97 in our store, or call 1 (570) 622-2848 to talk through your building’s specifics.
Straightforward returns: Standard shipping is included in the price via UPS, USPS, or LTL freight (expedited available on request). If a Slider arrives with a material defect, or you decide it’s not right for your application, we accept returns on unused product — buyer covers return shipping. No runaround, no restocking games.
Elevator and Upper-Floor Questions, Answered
Within the car’s rated capacity, yes — count the machine, the moving equipment, and the crew against it, and confirm the number with the building engineer before the move. Machinery Sliders™ help by spreading the load on the car floor instead of point-loading it through wheels.
Elevator door openings are shorter than the car — and skates add 4″–6″ under the machine. Sliders add just 3/8″ to 1″, so a machine that clears the door on the floor clears it on sliders. Measure the actual opening, not the spec.
Yes — non-point loading spreads the weight across each slider’s face, protecting tile, sealed concrete, and wood corridors that skate wheels crack and track.
Only if the elevator’s loading class permits it — under ASME A17.1, freight elevators are classified by how they’re loaded, and a car rated for general freight may not allow an industrial truck inside even under its weight capacity. Confirm the class with the elevator service provider.
The elevator’s rated capacity, loading class, and actual door dimensions, the freight elevator schedule, the lowest obstruction along the corridor route, and — for heavy machines — the building floor’s structural load rating, confirmed with the building engineer.
