Hook block

A component from the Tower cranes and lifting pack, with named material slots for construction lifting paint, construction site metal and construction site dark. It measures about 0.50 m × 0.77 m × 0.34 m (W × H × D) and comes as high, medium and low detail files. Place it on its own, or load one of the 2 included assemblies 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.
