New functions without additional components

Although originally developed for other vehicle types, High Level Braking (HLB) is now also available for fork lift trucks.

High Level Braking (HLB) saves installation space, reduces the complexity and optimizes the driving stability of fork lift trucks with hydrostatic travel drive

High Level Braking (HLB) from Bosch Rexroth reduces the braking distance, guarantees optimal driving stability and prevents the diesel engine from over-revving. Bosch Rexroth has now optimized this solution for the requirements of fork lift trucks. HLB for fork lift trucks is designed as an operating function for forward travel and reversing and does not require any additional components.

A hydrostatic travel drive is required for High Level Braking. In High Level Braking, an algorithm uses the overcenter operation of the Rexroth hydraulic motors in a targeted manner and disperses the majority of the braking energy via the high-pressure valves of the axial piston variable pump A4VG. To this end, the pressure cut-off must be mapped electronically. Fork lift truck manufacturers can thus dispense with the usual additional components such as retarders and service brakes. This saves installation space and reduces complexity.

In comparison with other applications, the fork lift truck brakes have a highly cyclical function. Frequent shunting movements, acceleration and braking are the norm. This is why HLB in fork lift trucks does not purely serve as an emergency braking function, but also has an operational function. It delivers the same braking performance in this application both when traveling forward and when reversing.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 29,500 associates generated sales revenue of approximately 5 billion euros in 2016.

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.
