This power unit is designed specifically for use on 2 and 4 post auto hoists. This is for raise-hold-lower of the lift, with manual control of the lowering speed. A pushbutton, mounted on the unit, starts the motor to raise the lift. The unit features a fixed relief valve, so the lift cannot be overloaded, but (depending on the cylinder size) can be used on most 7000 to 9000 lbs. (3175 to 4082 kg) capacity lifts. Cartridge valves are used, allowing easy field service and interchangeability. Air motor driven models also available. Power Unit shown is a representation of a typical unit....

This power unit is designed for smaller, low-rise auto hoists and can be mounted either horizontally or vertically, operating on AC power. A push button on the motor starts the unit to raise the vehicle on the lift. To lower, a manually operated cartridgestyle release valve is used for fingertip control of lowering speed. Power Unit shown is a representation of a typical unit. Actual unit may vary. 6

This power unit is designed for use on a double acting dump trailer or dump bed applications. Provides power lift-hold-power down operation. Two models available, with and without corded hand control, allowing the unit to be used as a replacement or as original equipment. Power Unit shown is a representation of a typical unit. Actual unit may vary. 7

The most common, rugged and reliable piece of truck equipment is the tail gate. The original Stone unit, now manufactured by SPX Fluid Power, has been used by manufacturers of this equipment since the industry began. Our 12V and 24V DC power packs come in manual or solenoid-operated versions for basic power up/gravity down tail gates. Power packs also available for cantilever and tuck-away designs of tail gates. Two button hand control is available for many DC lift/hold/lower applications. Steel or poly tanks available for custom design. Power Unit shown is a representation of a typical...

These power units are designed for use on elevated work platforms using a raise-hold and gravity lower circuit. The following additional features include: • Normally open valve to protect operators from run-on in case of motor contactor failures • Manual override to allow the platform to be lowered in case of power failure • AC ONLY: Electronic load delay for reliable operation in degraded voltage areas Power Unit shown is a representation of a typical unit. Actual unit may vary. 9

The power raise/gravity lowering circuit is ideal for Scissor Lift applications. While the circuit below will cover a wide range of scissor lifts, other pump, motor and tank capacities are available to suit various sizes. Power Unit shown is a representation of a typical unit. Actual unit may vary. 10

This hydraulic circuit has been specifically designed for Dock Levelers with a hydraulic lip. After powering the platform to its full height a sequence valve operates to redirect the oil flow to extend the lip. The valving ensures the lip remains extended until the pressure on the main lift ram has ceased. Power units vary from application to application. Submit application specifications to your distributor and our customer application engineering team can provide a specific quotation. Power Unit shown is a representation of a typical unit. Actual unit may vary. 11

This power unit is designed to operate all functions of a power operated angling snow plow. The unit includes a lift-holdgravity-lower function for the blade, with a continuous “float” capability. A directional valve controls angling of the blade, two cross-over reliefs protect the system from damage should the blade be obstructed while plowing. Power Unit shown is a representation of a typical unit. Actual unit may vary. 12

The DC power unit has been designed for truck applications with power lift, hold and gravity lower via a solenoid or manual release valve. Various tank sizes can be supplied to suit hydraulic cylinder capacities. Power Unit shown is a representation of a typical unit. Actual unit may vary. 13

The power unit has been designed for Dump Truck applications with power lift, hold and gravity lowering via a solenoid or manual release valve. Various tank sizes can be supplied to suit hydraulic cylinder capacities. An option to add a “tipper up” indication or warning pressure switch is available. Power Unit shown is a representation of a typical unit. Actual unit may vary. 14

The power unit is designed primarily to operate tines (or “spikes”) which pick up round bales and allow these to be hauled by a pickup truck, tractor or other vehicle. The unit incorporates a two position, four way cartridge valve and double pilot-operated checks to control a double acting cylinder, to lift, hold and then lower (under power) the round bale. It may also be used to power any double-acting,intermittent duty application. Power Unit shown is a representation of a typical unit. Actual unit may vary. 15
