Two leg sling

Lifting slings hang between a hook and a load, and this two leg version measures about 1.30 m wide and 1.49 m tall, with almost no depth at 0.05 m. It is a flat shape, best seen from the front.

In the Tower cranes and lifting pack it is used by the material hoist with lifting loads, and it sits with the hook block, hoist line, lifting cage and concrete skip among the pack's other parts. There is one named material slot, construction site metal, and three textures are embedded in the GLB.

The detail levels run from 1,276 triangles at high to 656 at medium and 228 at low, so the low level suits slings seen at a distance or in numbers. The model is safe to instance with InstancedMesh.

A component from the Tower cranes and lifting pack, with named material slots for construction site metal. It measures about 1.30 m × 1.49 m × 0.05 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-two-leg-sling/high-construction-lifting-two-leg-sling.glb');
scene.add(model); // 1 unit = 1 metre, origin at the mount socket
