Reliability

The use of ideally matched components and the stable machine design make the telescopic wheel loader extremely powerful and guarantee a long life. Reliable operations are possible in even the toughest conditions. The customer therefore has the machine power available when it is urgently required. The intelligent overload warning system consists of load torque limit and load torque indicator via display. These aids constantly inform the operator about the load situation and stability of the machine. Before the stability limit of the machine is reached in the forward tilting direction, the movements of the working hydraulics slow to a standstill. At the same time, when the maximum lifting load is exceeded, the operator is automatically alerted by visual warnings on the display and an acoustic signal. This means that the operator can work with safety and concentration, which significantly increases productivity.

Maintainability

The most important points for daily maintenance can be reached safely and conveniently from the ground. The entire engine compartment is accessible via just one enclosure. Quick and safe checks save time and money.

Brakes

Wear-free service brake due to hydrostatic driveline, applied to all four wheels and additional dual-circuit brake system, drum brake and wet multi-disc brake located in the front axle. Negative brake system in the front axle acting on the wet multi-disc brakes. The braking system meets the requirements of the ISO 3450.
