BOOM SUSPENSION Boom Suspension Solutions Ride control solutions fall into two categories: Passive or Active. Figure 1: Without Boom Suspension HydraForce suspension systems improve load-handling performance for wheel loaders and also enhance operator comfort by reducing vibration and improving ride control. Optimal combinations of cartridge valves in customized manifolds that feature an integral accumulator allow for smooth suspension of the boom. Passive Boom Suspension In a passive system, everything is pre-set – accumulator volume, precharge pressure and damping characteristics. How...

Bucket Brakes Steering Emergency Steering MAIN CONTROLS HydraForce offers valves that are well-suited to the unique needs of Dynamic Accumulator Charging Circuits which are commonly used in conjunction with steering and braking units. Hydraulic braking systems are common on wheel loaders and towable implements. These circuits require a delicate balance between the priority flow steering and braking sections of the application, while simultaneously allowing excess flow to be diverted to tank or various auxiliary functions. A typical circuit provides priority flow for the steering orbital...
