Machine skates are low-profile wheeled or roller units used to move heavy machinery and other rigid loads across a prepared floor. They support horizontal movement; they do not replace the jacks, lifting equipment, blocking, route assessment, or move plan needed to raise and control the load.
Choose a machine-skate system from the complete move, not only the total weight. Confirm the load mass, centre of gravity, base strength, support points, floor capacity, surface condition, route, turns, gradients, clearances, propulsion method, and the instructions for the exact skate and lifting equipment. Liftool's machine skates category shows available product formats, but the selected model's rating and manual must control the job.
Match the skate layout to the route
| Skate arrangement | Where it can fit | What must be verified |
|---|---|---|
| Fixed-direction skates | Straight or nearly straight travel on a prepared route | Alignment, support contact, load sharing, and how direction changes will be made |
| Steerable front unit with linked rear skates | Moves that require planned curves and controlled steering | Centre of gravity inside the support area, rear alignment, connection bars, turning clearance, and permitted pulling method |
| Rotating or multidirectional skates | Positioning where the load must change direction in restricted space | Rotation under load, coordination between units, floor condition, stability, and the manufacturer's operating sequence |
| Powered skate system | Repeated, long, or high-effort moves where the powered model is designed for the route | Complete system capacity, traction, braking, controls, battery or power limits, operator position, and emergency stop procedure |
These are selection categories, not interchangeable designs. A steering handle may guide one model but may not be an approved point for pushing or pulling another. Mixing individual skates, handles, turntables, spacers, or connecting bars is acceptable only when the manufacturers or a competent engineered plan approve the combination.
Start with the load and centre of gravity
Record the machine's actual mass and centre of gravity before selecting equipment. Drawings, manuals, nameplates, recent modifications, removable tooling, tanks, fluids, and moving assemblies can all affect the result. A nominal machine weight is not enough when one support point may carry much more than the others.
The April 2025 DGUV FBHM-142 guidance for machinery moves with hydraulic jacks and non-powered transport skates says the load, centre of gravity, lifting areas, support points, transport equipment, route, and environmental conditions must be considered. It also explains that the centre of gravity must remain inside the support polygon and describes a connected three-point arrangement as especially stable in practice because it can accommodate small floor irregularities. This is German occupational-safety guidance for its stated scope, not a universal approval of every three-point kit.
Do not assume that adding the nameplate capacities of several loose skates proves the system is adequate. Verify whether a rating applies to one unit, a paired rear assembly, or a complete set; how the manufacturer expects the load to be shared; and whether the contact area can support the base without bending, crushing, or slipping. Allow for an off-centre load and for load transfer during starting, turning, crossing minor surface changes, and stopping.
Check the floor and the complete route
Walk and measure the route before the load is raised. Confirm:
- the floor can support the concentrated wheel or roller reactions, including over ducts, covers, trenches, joints, ramps, and suspended slabs;
- the travel surface is clean, level, firm, and compatible with the selected wheels;
- doorways, corners, columns, equipment, overhead restrictions, and final positioning clearance are adequate;
- gradients, thresholds, cracks, debris, wet or oily areas, and weather exposure are eliminated or covered by an engineered method; and
- pedestrians and unrelated work can be kept outside the movement and potential tip or crush zones.
Wheel material is an application choice, not a guarantee of floor protection. Steel, nylon, and polyurethane wheels differ in rolling resistance, contact pressure, durability, debris sensitivity, and suitability for particular surfaces. Obtain the floor limits and wheel data rather than assuming that a non-marking wheel makes an unknown floor safe.
Plan the lift onto the skates
Raising the machine is a separate lifting operation. Identify manufacturer-approved lifting or jacking points, use correctly rated equipment, lift only as high as necessary, and use suitable blocking so the load is not supported by hydraulic pressure alone while people position equipment. Do not put hands, feet, or other body parts beneath an unsupported load.
The UK's HSE guidance on safe lifting by machine calls for the lift to be planned by a competent person, appropriately supervised, and carried out safely. It asks users to establish the load, weight, centre of gravity, attachment method, person in control, and equipment limits. Its legal references apply in Great Britain; other locations must use their own applicable requirements.
Lower the load onto the planned support points gradually. Confirm that every intended pad is fully seated, the skates remain aligned, connections are secure, and the centre of gravity is inside the support layout before removing the jacks and blocking. If the machine base is irregular or not strong enough at those points, use an engineered frame or load-spreading arrangement rather than improvised packing.
Move slowly and stop when control changes
Assign one person to direct the move and agree on signals and stop commands. Keep everyone away from the travel line, pinch points, the inside of turns, and any place the load could tip or roll. Apply force smoothly; do not jerk, shock-load, or try to force a skate through an obstruction. Use a towing device only when the complete skate system, connection, towing vehicle, braking method, and route are approved for it.
Enerpac's model-specific MLSF, MLSD, and MLSR load-skate manual requires a flat, level floor capable of supporting the load and instructs users to move slowly and carefully in a controlled direction. It also distinguishes the operating details of steerable, linked rear, and rotating units. Those instructions support selection and operating checks for the named Enerpac families; their dimensions, capacities, handle rules, and clearances are not universal specifications for other skates.
Stop immediately if a skate jams, turns out of alignment, unloads, begins to escape from under the machine, or shows damage; if the load shifts or tilts; if the route or floor changes unexpectedly; or if communication or braking control is lost. Stabilize the load with the planned method before anyone approaches or attempts to reposition a skate.
What to send with a machine-skate enquiry
Provide the machine mass and dimensions, centre-of-gravity information, base drawing and support points, required travel and final orientation, floor construction and condition, route length, turns, gradients, thresholds, minimum clearances, preferred propulsion method, operating environment, destination market, and documentation needs. Also identify the proposed hydraulic or toe jacks and how the load will be blocked during placement.
Send these details, route photos, and machine drawings to Liftool. A useful quotation should identify the skate arrangement, capacity basis, wheel material, steering and connection components, and any assumptions that still require confirmation before the move.
