PUTTING SOME LEG INTO IT: 'Spider' excavator targets demanding jobs in impossible locations: hydraulics key to machine maneuverability

摘要

Excavators by Swiss manufacturer Menzi Muck are also referred to as "spider" excavators - and it's not difficult to see why. These types of "walking" excavators are very specialized machines that are mainly used in difficult working areas, such as steep slopes and streams. They move forward on four wheels connected to the undercarriage by legs, which are used to adjust the track width and height of the vehicle with a wide range of possible combinations. Though originally developed for construction applications, they frequently are also used in forestry and agricultural applications, where operating in challenging terrain is not an unusual occurrence.
