Tower slew

A component from the Tower cranes and lifting pack, with named material slots for construction site dark, construction site metal, construction lifting paint and construction site glass. It measures about 3.00 m × 2.10 m × 3.10 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.
