Construction Machinery

Excavators, wheel loaders, pavers or concrete mixers – construction machinery has to combine maximum performance and precision. This requires high-performance drive and control systems. Moreover, with rising energy costs, high efficiency levels are imperative as well. At the same time, emissions must be lowered significantly and the specific requirements of regional markets need to be met. Faced with all these challenges, the construction machinery industry can rely on Bosch Rexroth and the company's long years of system know-how, application experience and innovative products.

Bosch Rexroth equips manufacturers of construction machinery with specific solutions for compliance with US TIER 4 final and Euro Stage IV. Downsizing concepts are an important element in these solutions: With the help of high-performance hydraulics, customers can reduce the nominal engine output of, for instance, a compact loader while maintaining or even improving performance. The Bosch Rexroth downsizing concept increases overall system efficiency to minimize emissions, fuel consumption and space requirements using smaller engines.

Successful downsizing is based on high-efficiency hydraulic systems: With the Hydraulic Fly Wheel (HFW), for instance, unused energy can be stored and made available on demand. HFW can be used for power smoothing, downsizing the diesel engine or as a boost function.

Electronically controlled hydrostatic fan drives from Bosch Rexroth reliably keep combustion engines at their optimum operating temperature, even under the most difficult operating conditions. This enables fuel consumption to be lowered by up to five percent. As a result, hydrostatic fan drives enable operators to comply with regulatory requirements such as TIER 4 final and Euro Stage IV.

Another example: The Diesel Hydraulic Control (DHC) functional module ensures that diesel engine and hydraulics work together in the most efficient way possible. This increases the machine's overall efficiency and provides the exact amount of energy needed. With DHC and other Rexroth solutions, manufacturers and users can lower their machines' fuel consumption significantly – with optimum system dynamics.
