Concrete skip

The concrete skip measures about 1.45 m wide, 1.64 m tall and 1.40 m deep, with one unit equal to one metre, so it drops into a metric scene without rescaling. It comes from the Tower cranes and lifting pack and appears in the Material hoist with lifting loads assembly. Three named material slots, construction lifting paint, construction site dark and construction site metal, let you recolour it separately.

Detail levels run from 1,756 triangles at high, through 844 at medium, to 332 at low, so a few skips near the camera can use the high level while a whole site of them can sit on the low one. The model is safe to instance with InstancedMesh. In the same pack it pairs with the hoist line, hook block, lifting cage and pallet fork.

A component from the Tower cranes and lifting pack, with named material slots for construction lifting paint, construction site dark and construction site metal. It measures about 1.45 m × 1.64 m × 1.40 m (W × H × D) and comes as high, medium and low detail files. Place it on its own, or load one of the 1 included assembly that use it.

The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.

Included in Tower cranes and lifting (£19), which contains 22 component models and 3 assemblies.
