This aluminum hydraulic manifold is stamped with detailed information for easy identification when performing maintenance. The assembly also contains electronic controls for operating valves and system communication.
In the new design, a large central manifold (shown) is mounted low in the machine to keep the center of gravity low. The integrated hydraulic circuit controls forward and reverse motion, steering, and leveling. Mounting the electronic controls directly to the hydraulic manifolds is key to minimizing the amount of hoses and wiring required.
The other three integrated packages on the tire handler manage the motion of the machine’s manipulator arms and safety locks. In all, the four packages incorporate 36 Sun proportional valves and multiple check valves. Separate counterbalance valves are used with in-line manifolds mounted directly on the cylinders and wheel-hub motors for extra safety. Furthermore, aluminum manifold blocks, rated to 3000 psi, are used to reduce vehicle weight. They are stamped for easy part identification and anodized for corrosion protection.
The machine is controlled entirely by six High-Country Tek HCT DVC 710 controller modules that network to each other using the SAE J1939 digital standard to minimize wiring and ensure reliability.
