# Tracked excavator with hydraulic breaker (Demolition and Site Clearance)

The same excavator with the bucket swapped for a hydraulic breaker: a charcoal hammer box on the quick coupler with a moil point chisel and hose stubs, hung off the boom as a parented node so it travels with the raise, the tool a controlled demolition works a slab with.

## About

The same excavator with the bucket swapped for a hydraulic breaker: a charcoal hammer box on the quick coupler with a moil point chisel and hose stubs, hung off the boom as a parented node so it travels with the raise, the tool a controlled demolition works a slab with. Free 3D model for demolition, site clearance and construction game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 2.76 by 4.11 by 7.62 m (X by Y by Z). Metre units, +Y up, the working face toward +Z, resting on y=0 with the origin on the footprint. The breaker hangs off the boom as a parented node, so raising the boom carries the breaker with it. Rigid node-transform clips: open and close. No skinning. The breaker never strikes: a hammer blow is a percussion cycle inside the tool, not a joint, so the chisel, the hoses and the accumulator are modelled solid. The track belts and every ram are solid too. No plant manufacturer name, badge or model number appears anywhere. No plant manufacturer, demolition contractor or equipment brand name, badge or artwork anywhere: every livery is invented and every sign face and plate is blank.

## Use with three.js

```js
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'
import { AnimationMixer } from 'three'

let mixer

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/35687/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
  mixer = new AnimationMixer(gltf.scene)
  mixer.clipAction(gltf.animations[0]).play()
})

// Call from your render loop; deltaSeconds is time since the previous frame.
function updateAssetAnimation(deltaSeconds) {
  mixer?.update(deltaSeconds)
}
```

## React Three Fiber

```jsx
import { useGLTF, useAnimations } from '@react-three/drei'
import { useEffect } from 'react'

export function TrackedExcavatorWithHydraulicBreakerDemolitionAndSiteClearance(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/35687/v1/model.glb')
  const { actions, names } = useAnimations(animations, scene)
  useEffect(() => {
    const action = actions[names[0]]
    action?.reset().play()
    return () => { action?.stop() }
  }, [actions, names])
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/35687/v1/model.glb')
```

## <model-viewer>

```html
<model-viewer src="https://cdn.3dassets.dev/assets/35687/v1/model.glb" alt="Tracked excavator with hydraulic breaker (Demolition and Site Clearance)" camera-controls auto-rotate autoplay></model-viewer>
```

## Blender

```python
# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.
import bpy
bpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/35687/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
# Clips arrive as actions; play them from the Dope Sheet > Action Editor.
```

## Godot

```gdscript
# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.
var packed := load("res://models/model.glb") as PackedScene
var model := packed.instantiate()
add_child(model)
var player := model.find_child("AnimationPlayer", true, false) as AnimationPlayer
player.play(player.get_animation_list()[0])
```

## Unity

```csharp
// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,
// or load it at runtime straight from the CDN:
using GLTFast;
var gltf = new GltfImport();
if (await gltf.Load("https://cdn.3dassets.dev/assets/35687/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
