A light touch is all you need for steering and braking – even for a 30-ton machine. And that’s not all. The steering movements should be transmitted precisely and directly. The brakes should respond quickly and directly, and yet be sensitive and easy to regulate. The wheel loader as a work place thus becomes safer and more comfortable, the wheel loader as a work tool gets more efficient and maneuverable.
In the LAG steering units from Rexroth you have what is probably the most versatile steering system on the market. Its large number of variants enables it to be matched perfectly to the vehicle. This is the case whether open-center for closed-center, and whether with standard or special emergency steering function. The right module for every situation. All versions officially approved, and successfully tested thousands of times. Rexroth steering sensors on the steering column reliably combine steering and electronics. To meet legal requirements, very heavy wheel loaders also have the A10VWO emergency steering pump or the EHP compact unit.
The LT31 inch brake valve which like many other Rexroth power braking valves has a proven record and a modular and compact design provides a smart combination of diesel-engine braking via the travel hydraulics and delay from the friction brake. When the brake pedal is actuated, the hydraulic pump reduces the flow rate from the travel drive. Braking thus takes place using the diesel engine’s support torque. Only if the pedal is pressed harder does the brake valve ensure that the brake linings make contact. This hydraulic power brake, which is integrated in the overall design of the vehicle, offers a number of advantages for wheel loaders:
Advantages of hydraulic power braking systems
- Supplied from existing hydraulic system
- Brake system immediately ready with start of diesel engine
- Brake system can be regulated sensitively, even in heavy machines
- Quick response time
- Space saving through modular design
- Minimal pipework required due to compact design (pedal and all brake components combined in a single block)
