<strong>Bosch</strong> <strong>Rexroth</strong> helps Terex solve pump problems<br />
When Terex Equipment, one of the UK’s leading developers and<br />
manufacturers of off-highway earth-moving equipment needed a<br />
hydraulic pump to supply emergency power for the steering in its<br />
new TA35 and TA40 ranges of articulated dump trucks, the<br />
requirement seemed deceptively simple. But, as it turned out, only<br />
one pump manufacturer – <strong>Bosch</strong> <strong>Rexroth</strong> – was able to supply the<br />
right product for the job.<br />
Large off-highway vehicles are very dependent on hydraulic power in<br />
particular, without it they are impossible to steer. To ensure that steering<br />
control can be maintained even if the main hydraulic power pack fails while the<br />
vehicle is in motion, an auxiliary pump, driven from the wheels, is fitted to<br />
provide a source of emergency hydraulic power for the steering systems.<br />
The Terex engineers found, however, that sourcing a suitable pump for its new<br />
dump truck ranges presented a considerable challenge.<br />

FOR IMMEDIATE RELEASE<br />
A major complication was that the pump had to operate correctly irrespective of<br />
whether the vehicle was moving forward or backward. There was also very<br />
limited space on the vehicle to accommodate the pump. Finally, Terex wanted<br />
a solution based, as far as possible, on standard off-the-shelf components to<br />
avoid future delivery and availability problems.<br />
“We’ve known <strong>Bosch</strong> <strong>Rexroth</strong> for many years, and we’ve always been very<br />
happy with service offered by the company and by its products,” said Susan<br />
MacDonald, Terex Product Manager for Articulated Vehicles, “so we naturally<br />
asked the company to quote for the pumps. We also approached several other<br />
suppliers, with the objective of having a number of alternative solutions from<br />
which to choose.<br />
“However, <strong>Bosch</strong> <strong>Rexroth</strong> was the only company to offer a suitable solution,”<br />
she continued. “Not only would its pump fit within our very tight space<br />
envelope, it would also couple easily and directly with the spline of the power<br />
take off (PTO) point on our gearbox.”<br />
The solution developed by <strong>Bosch</strong> <strong>Rexroth</strong> comprises a pump from the<br />
company’s standard range, used in conjunction with a rectifier block, which<br />
ensures that the pump itself receives a uni-directional drive, irrespective of the<br />
direction of motion of the vehicle.<br />

FOR IMMEDIATE RELEASE<br />
“The TA35 and TA40 are completely new vehicles,” said Susan MacDonald,<br />
“so there were many unknowns in the early stages of the project. However, we<br />
received exceptional support from <strong>Bosch</strong> <strong>Rexroth</strong> throughout our design work.<br />
The company even flew in engineers from Germany to assist with<br />
commissioning and with the validation of our prototype vehicle.”<br />
Because of the flexibility, expertise and enthusiasm it demonstrated in<br />
addressing the challenges which Terex faced with its auxiliary steering pumps,<br />
<strong>Bosch</strong> <strong>Rexroth</strong> was subsequently asked to work with Terex engineers in<br />
developing a design for the main hydraulic system of the new vehicles. Once<br />
again, lack of space was a major concern.<br />
This lead the <strong>Bosch</strong> <strong>Rexroth</strong> team to propose an innovative solution based on<br />
the use of two pumps mounted back-to-back and operating in tandem. Not only<br />
did this produce a very compact assembly, the back-to-back arrangement also<br />
meant that only one PTO point was needed on the gearbox instead of two for<br />
the arrangement used by Terex on earlier concepts.<br />
A further benefit of the new arrangement is that the pumps incorporate load<br />
sensing, which makes their operation much more efficient than the open-loop<br />
pumps which had been adopted in earlier designs.<br />
