Crawler Excavator, 20-Tonne Class (Rigged & Animated: Boom, Stick, Bucket, Swing, Tracks, Cab)

A game-ready heavy-equipment hero asset: a 20-tonne class crawler excavator in construction yellow, unbranded, built as a working machine rather than a statue.

The arm works the way the real one does. Two boom cylinders, the arm cylinder and the bucket cylinder each stay pinned to their lugs through the whole stroke, and the bucket's dogbone and H-link linkage is solved for every frame, so nothing slides, stretches or folds. The hydraulic hoses run low past the pins in sleeved bundles and pay out as the joints move. The cylinders have bolted glands with wiper seals, chrome rods, bushed eyes and grease nipples; every pin has a thrust washer and a bolted retainer.

The undercarriage is built shoe by shoe: grouser plates bolted to their links, bushings and pins, a sprocket whose teeth meet the bushings, a turned idler on its fork and tensioner, double-flanged bottom and carrier rollers, a cast final drive and a welded frame with its guard. In the drive clips the shoes travel round the loop and every wheel turns.

The cab is fitted out: a two-tone seat with an orange belt, grey moulded consoles with booted joysticks, a red safety lever, two travel levers rising from their pedals, a monitor and a grade-control tablet with drawn screens, vents, placards and door hardware, behind tinted glass that ships see-through.

The paint carries weathering with causes, baked into the textures: faded tops, grime round the joints and hydraulics, chips at the steps, edges and linkage, touch-up patches, a dirty undercarriage, and a bucket polished bright along its cutting edge and scuffed where it digs.

Rigged on 141 bones, so you can drive any joint yourself, and three sockets: the driver's seat, the bucket tip and the cab door handle.

Clips: DriveForward, DriveReverse, PivotLeft, PivotRight, SteerLeft, SteerRight (tracks, loops), BoomRaise, BoomLower, StickOut, StickIn, BucketCurl, BucketDump, SlewLeft, SlewRight, TravelPose, DigCycle, DoorOpen and DoorClose, plus a still rest pose.

Includes FBX (skeletal mesh plus one FBX per clip for Unreal), a GLB with every clip embedded, and baked colour, normal, roughness and emission maps in five texture sets (4K house, 2K arm, cab, bucket and undercarriage). 268,200 triangles; 5.6 m tall at rest.
