Menzi Muck walking excavators

The walking excavators' special features are based on a sophisticated high-tech chassis and the patented boom: various hydraulic cylinders enable the all-rounder to adapt its wheels and supports to any terrain. For this in some countries the Menzi Muck is also called spider excavator.

Fixed tilting edges on Menzi Muck tracked excavators can be adjusted depending on the task ahead thanks to the adjustable wheel and claw supports. As a result, it produces lifting and ripping forces beyond those of conventional excavators. A Menzi Muck weighing 9.5 tons produces an output similar to that of a 20 ton tracked excavator.

Innovations

Worldwide innovation: Menzi Powerboom

There is a lot of innovation in the new and unique excavator arm of the M Series. Unique to Menzi Muck, the boom cylinder is arranged horizontally in the centre part. Collisions at the boom cylinder are therefore impossible.

Wide-angle kinematics with power booster

The new kinematics of Menzi Muck opens new dimensions: optimum work in the close-up range at the minimum possible swivel radius is contrasted with maximum stretching of the boom. The Menzi power booster thereby supplies the highest possible forces over the whole working range.

 

 

 

 

Panorama cockpit

A free view of the entire working environment, the support and the wheels provide the driver with safety and complete control in all situations. The spacious cab provides a perfect sense of space and many practical details for relaxed working.
