Wheeled Excavators

Wheeled excavators are a variation of the popular crawler excavator, switching the latter’s tracks for a four-wheel-drive undercarriage. Wheeled excavators typically use powerful planetary axles, which are designed to oscillate and allow the machine to negotiate uneven terrain. A primary advantage of the wheeled excavator is its mobility, allowing it to be driven rather than transported to a jobsite. Most models use hydraulically extendable outriggers to help stabilize the machine when digging.
