Control system for a valveless wheel loader

Implementing energy-efficient drive technology in mobile machines reduces fuel consumption, cutting costs for users. To ensure acceptance, these new drive technologies must maintain the same standards of operability and machine performance that users are used to. This represents a huge challenge in terms of developing the control system, as in-depth understanding of machine behaviour and drive technology is required.

Developing and commissioning a concrete paver

The concrete paver was taken into operation after being successfully developed and commissioned with considerable help from Hydrive. It has now been in use on various construction sites for over six months.

3D visualisation supports software development

As part of the joint project Developing Technologies for Energy-Efficient Drives in Mobile Machines Hydrive Engineering GmbH has added a 3D visualisation feature to a software test rig for the first time. The system’s particular advantage is that it is able to directly import data from the real-time simulation models of machines already available, eliminating an additional step in the modelling process.

5th Technical Conference for Construction Equipment in Dresden

Hydrive Engineering presented itself for the first time at the Technical Conference for Construction Equipment (Fachtagung Baumaschinen), which was held in Dresden in September 2012, as a competent partner for the development of fluid power drive components and systems.

Swivel drive for a hydraulic excavator

An automated software testbed for the simulation of electrical faults in the cable loom and their recognition by the control software was developed and built during the software development for a hydraulic excavator. This considerably reduced expenditure on tests for proving safety functions in the event of a fault.

Hydraulic system for a road finishing machine

A complete hydraulic system, which met the requirements in terms of controllability, precision dosing control and energy efficiency, was developed for a road finishing machine.

Software test rig for construction equipment industry

Hydrive Engineering has developed a test rig that tests the functional safety of excavator controller software on behalf of a construction equipment manufacturer.

Operating concept for a construction machine

A concept for an electro-hydraulic control was developed for the tools of a grader which considerably simplified the operation of the machine, as well as increasing its performance.

Additional traction drive for a construction machine

A hydrostatic additional traction drive which has to run synchronously with the traction drive of the machine under all operating conditions was developed from scratch for a grader.
