Crane Material Transfer Platform
A material loading platform is a temporary steel platform that projects out from a building floor, where a crane lands materials and workers move them into the floor. It is how materials get onto each level of a high-rise without blocking the stairs or the hoist. Lengge makes both types: the cantilever platform, with steel beams that project from the floor edge and tie back to the structure, and the mobile platform, which rolls out through an opening on wheels. Both have a steel deck, guardrails and a rated safe working load.
We build them to your floor edge, opening and rated capacity, using the same beams and anchoring as our cantilever scaffolds. Factory-direct for high-rise contractors worldwide.

A material loading platform is a temporary steel platform that projects out from the edge of a building floor, used to transfer materials onto that floor. A crane lifts a load and sets it down on the platform, which reaches out past the building edge, and the crew then moves the material off the platform and into the floor. It is the standard way to get materials onto the upper levels of a high-rise without blocking the hoist or the stairs.
A cantilever platform is fixed: steel beams project from the floor edge and tie back into the structure, carrying the load out over the edge, and it is relocated by crane. A mobile platform sits on the floor slab on wheels and rolls out through an opening in the edge protection; it can be pulled back in and moved to another bay or floor without a crane. Cantilever suits a fixed loading point; mobile suits a platform that has to move around.
It is built as a safety platform. The cantilever type ties back into the structure so the load is carried safely over the edge; the mobile type is counterweighted or anchored so it cannot tip as it is loaded. Both have a steel deck, guardrails and toe boards around the open sides, and a gate or chain across the loading edge that is closed once the crane load is landed, so the crew always works behind the rails.
Every platform is rated to a safe working load, which is marked on it, and that rating must not be exceeded. The capacity is set by the design and by the structure the platform ties to or sits on, so it is matched to the loads the platform will carry. Common capacities run from around a tonne to a few tonnes, but the marked rating on your platform is the figure that counts.
The frame and deck are steel, painted or galvanized. The deck is steel plate to take the point loads of landed material, the frame carries the load back to the structure, and the guardrails and gate are steel. Galvanizing or paint protects it through repeated use and outdoor exposure on site.
Yes. We build loading platforms to your site, in cantilever and mobile types, to the dimensions and rated capacity you need, supplied with the beams, tie rods and anchoring. We ship in containers and handle export packing and documents. Tell us the floor edge, the opening and the loads and we build to suit.
On a high-rise, the tower crane does the lifting, but it cannot set a load down inside a floor, the floor edge and the building are in the way. The material loading platform solves that: it projects out past the edge so the crane can land a load on it, and the crew moves the material off and into the floor from behind the guardrails. This page covers what it does, the two main types, and the safety basics.
A loading platform is the landing point for craned material on each working level. Without one, getting pallets of block, bundles of rebar, formwork panels or stacks of props onto an upper floor is slow and awkward, and tends to clog the hoist and the stair core. With a loading platform on each level, the crane drops material straight onto the platform, the level is served quickly, and the same platform is used to send surplus and waste back down. It is a basic piece of high-rise logistics.
There are two common types, and many sites use both:
| Type | How it works | Relocated by |
|---|---|---|
| Cantilever (fixed) | Steel beams project from the floor edge, tied back to the structure | Crane |
| Mobile (wheeled) | Rolls out through a floor opening on wheels, counterweighted | By hand or small machine |
The cantilever platform is a fixed loading point: steel beams reach out from the floor edge and tie back into the structure, carrying the load over the edge, and it is moved up the building by crane as work rises. The mobile platform sits on the floor on wheels and rolls out through an opening in the edge protection, so it can be drawn back in and repositioned between bays or floors without a crane. Cantilever suits a permanent loading bay; mobile suits a platform that has to move around the floor plate.
A loading platform carries heavy loads out beyond the building edge, so it is a safety-critical item. Three things matter most. First, the rated safe working load: every platform has a marked capacity set by its design and the structure it ties to, and it must never be overloaded. Second, the tie-back or counterweight: the cantilever type ties firmly into the structure so the load is carried safely over the edge, and the mobile type is counterweighted or anchored so it cannot tip while it is loaded. Third, the edge protection: guardrails and toe boards around the open sides, and a gate or chain across the loading edge that is opened only while the crane lands a load and closed while anyone is on the platform.
Loading platforms are steel, painted or galvanized, with a steel-plate deck to take point loads. They are built to the site: the platform size to the floor edge and opening, the type to how the loading point has to move, and the rating to the loads it will carry. Because the cantilever type uses the same beams, tie rods and anchoring as a cantilever scaffold, a supplier who makes both can build the platform on a proven load path and match it to the rest of the temporary works. Confirm the rated capacity, the type and the deck size against your site before ordering.
