Mobile chassis

A component from the Tower cranes and lifting pack, with named material slots for construction site dark, construction lifting paint, construction site rubber, construction site metal, construction site glass and construction site panel. It measures about 8.41 m × 2.65 m × 2.70 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.

Load it in three.js

import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';

const loader = new GLTFLoader().setMeshoptDecoder(MeshoptDecoder);
const { scene: model } = await loader.loadAsync('models/construction-lifting-mobile-chassis/high-construction-lifting-mobile-chassis.glb');
scene.add(model); // 1 unit = 1 metre, origin at the mount socket
