TABLE OF CONTENTS Mini and mid-range excavators up to 20 tons can gain the greatest benefit from inventive application of electrohydraulic controls. Virtually all movements of the cab, boom, arm, and bucket are hydraulically controlled and easy to integrate into hydraulic manifolds. HydraForce, with its comprehensive line of cartridge valves and manifold capabilities, can provide numerous custom control solutions for excavators. Fixed or adaptable Improved safety Efficiency Increased functionality Wide range of adaptable solutions for precise control Stand-alone or custom manifold designs Flow...

Transmission Drive Motors Fan Drives Clutch POWERTRAIN Excavator Transmission Solution Excavator powertrain solutions encompass improvements on the transmission, drive motors, fan drives and clutch. Reducing emissions, noise, and vibration and improving speed, power and cooling are the goals. Operator comfort and productivity can be enhanced with improved fan and transmission control. Here are some ideas. Four TS98-T34 valves are used to shift clutch packs. The TS98-T34 valve is a cost-effective, pilot-operated, spool-type proportional pressure reducing/relieving valve with a built-in solenoid...

Bucket Control Arm Control Boom Control Pressure Spike Solution Basic Boom Suspension Circuit Here’s a clever way to solve the issue of pressure spikes. An EP valve can be used to reduce the overshoot spike in a closed center load-sensing system by popping open momentarily, allowing the hydraulic pump time to de-stroke when needed. As long as the spring value of the valve is slightly higher than the low-pressure standby setting of the pump, the valve will stay closed until the cylinder bottoms out. Since load-sense pressure is not maintained, the valve will open while the pump de-strokes, which...

Boom Bucket Swing/Slew Motor Steering MAIN CONTROLS Excavating on a mountainside or in a riverbed can be easily accomplished with the help of a “walking” excavator. Its wheels are mounted on foldable “legs” that are controlled hydraulically by the same manifold that provides steering control. When the excavator works in a riverbed, the manifold and cartridge valving can be totally submerged in water, thanks to their corrosion-resistant coating. As excavator power and sophistication increase, so do flow rates. HydraForce SPCL16-40 valves control up to 152 lpm (40 gpm) while holding loads with...

Breaker Grapple Hammer Auger Quick Coupler ANCILLARY FUNCTIONS Excavators, especially the mini- and midi-sized models, can do much more than earthmoving and excavation. With the right attachments, an excavator can also be used for demolition, drilling, and material-handling – all with the power of electro-hydraulic control. Hammer Valve for Breaker Quick Coupler Manifold Pilot Control Manifold for a Mini-Excavator Grapple This circuit provides responsive and smooth control of the fixed gear pump system for the breaker on a hydraulic excavator, using a solenoid valve, compensator, needle valve...

HydraForce Vision The HydraForce story began in 1985 when the company was founded near Chicago by several partners who saw the mobile equipment industry’s need for quality hydraulic cartridge valves and manifolds delivered in a timely and responsive manner. They also saw the potential for engineering innovation and design flexibility offered by cost-effective and space-saving cartridge valves and hydraulic integrated circuits. To Be An Independent Provider Of Innovative Technical Solutions That Can Change The World Mission Statement To Provide Our Customers With The Highest Quality Hydraulic...
