The mobile multi-purpose excavator. The Menzi Muck M5. The new generation of Menzi Muck is based on long-standing experience. Since their debut, the world‘s best-selling machine in their weight class has passed through various evolutionary stages. New technologies, ecological and economic aspects, customer suggestions and practical experience have been packaged in a new version. The convincing result: optimized efficiency with increased cooling, low noise values and minimized fuel consumption. The various model designs feature the same top section but have different chassis. Depending on the application of the mobile multi-purpose excavator, numerous options in the module system are available for creating tailored solutions. Thanks to continuous performance enhancements, greater mobility and powerful drive technologies, new and interesting applications have been developed for the Menzi Muck in addition to its original use on steep slopes and also on lowlands. It delivers an above-average hydraulic performance for its weight. The result is a powerful tool carrier with maximum ground preservation. Thanks to the adjustable chassis, the benefit of progressive movement on difficult terrain is offered by all model variants.

APM – up to 30% fuel savings
The APM controller (Anticipating Power Management) creates a new, fast and harmonic interplay between the motor and the hydraulics. Overloading is thereby reduced to an absolute minimum. Power, Eco and Fine mode provide extra help in efficient operation of the machines. Powerlift function for maximum forces.

Hydraulic system
Optimized hydraulic tuning has been a Menzi tradition. The harmonious operating cycle is geared towards smooth and optimized performance. Sensitive LUDV Load Sensing Hydraulic. Two capacity controlled swash plate axial piston pumps (P1/P2) for the working hydraulic and drive and a third controlled swash plate axial piston pump (P3) and a gear pump for fan drive.

Cooling system
Generously dimensioned cooling system (pull). Three separate coordinated cooler elements for hydraulic oil/ charge air/ water maximum cooling capacity through side-by-side arrangement of the cooling elements. Variable fan motor. Optional: swing condenser-element for air-conditioning.

Swing
An axial piston motor with automatic multidisc brake acts on the internal gears of the double-row slewing ring via a planetary gear. Hardened tooth profiles. A proportional, demand-driven torque control is applied to regulate the turning force via the joystick. Swing range 360° endless. Swing speed up to 10 rpm. Swing torque 52’000 Nm.

Hydraulic cylinders
The hydraulic cylinders are again from our own design and manufacturing. Cylinders on the chassis are equipped with check valves (safety hose break). All cylinders on the boom assembly are equipped with cushioning.

Load limit control
Load Sensing hydraulic system by Bosch-RexrothElectronic load limit control for fast, smooth and constant interaction between engine and hydraulics. An additional operating mode is provided: In smooth mode, work to the millimetre can be carried out at full power

World innovation: Menzi powerboom
There is a lot of innovation in the new and unique boom of the M-series. Unique to Menzi Muck, the boom cylinder is mounted horizontally in the center 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.

Powerline - when power is the key
A separate pump supplies the additional connection of up to 190 l / 50 US.-gall. per minute. A consistently high oil supply increases therefore the efficiency of the accessories significantly. Volumes and pressures can be programmed individually.

The Menzi Muck M540 and M545.

M540 with H-Drive system.
Powerful drive.

The intelligent Menzi H-Drive control with torque overlay optimises efficiency in any operating position. The power is distributed over the four drive wheels in such a way that the highest possible traction is automatically achieved. Drive components with even more traction round out the new Menzi drive concept.

Road Traction module.
Maximum ground preservation
.
An additional hydraulic lock can be switched on and off to allow a setting between maximum traction and maximum ground preservation to be selected via the RTM module.

Drive potentiometer.
Speed as required.

All product variants features a potentiometer for the traction drive. The maximal speed can be individually set – the accelerator pedal is released more smoothly.

M545: All-wheel sensor steering.
Unbelievable agility.

The all-wheel sensor steering achieves a turning circle of less than 10 meters. Eight steering sensors ensure the correct angle is calculated for the four wheels. The wheels are automatically moved to the correct position, which guarantees extended tyre life. There are five different steering designs to choose from:
1) Stub axle steering.
2) Automatic all-wheel steering.
3) Crab steering.
4) Parallel rear steering.
5) Hydraulic steering (without sensors).

P-Matik stabilizers.
More ground clearance.
Consistent ground clearance in any position, as well as a permanent pivot point of the stub axle steering guarantees the parallelogram of the Menzi P-Matik stabilizers.
