S-Valve Manifold
Directs oil flow to either shift cylinder. Accumulator pressure is also utilized to control the main pump controllers. All electrical functions have manual over-rides.

Main Pump Cell Manifold
Directs oil to the pumping cylinders. All electrical functions have manual over-rides. The main pumping system is an open loop circuit, which reduces heat in the hydraulic system.

Boom Control Valve
The Hawe Controller Valve operates the boom functions and supplies oil for the outrigger circuit. This valve is fully proportional.

Main Pump
This is the main pump which delivers oil for the pumping cylinders. Accumulator pump, boom pump and accessory pumps are all Roxroth.

Hydraulic Oil Cooler
The fan is operated by a hydraulic motor for efficiency and maximum cooling and is controlled by a temperature sensor, with a manual over-ride.

Radio Remote Controls
Our standard package is equipped with Omnex Radio Controls, including two transmitters. The transmitter can also be utilized as a hard wire controller. The data cable plugs directly into the transmitter and into the receiver making the transmitter a proportional hard wire box. With the hard wire plugged into the transmitter, the battery is not necessary.

Hawe Load Holding Valve
Industry standard on boom cylinders to hold the boom in position.

Boom, Outriggers and Turret
Structures are all made of Oxelosund-Weldox structural steel.

Split Panel
Common relays are utilized along with ATO fuses. The smaller switch panel at the rear of the pump minimizes clutter and eliminates long wiring looms that deteriorate with time.

EasyClean 600L Hopper
Carbide Tungsten wear parts and 60mm agitator shafts.

Hopper Vibrator
Standard on all Boom Pumps and Truck-Mounted Line Pumps, our Hopper Vibrator helps you tackle those harsh mixes.

Hopper Auto Lube
Moving parts in the hopper assembly are lubricated by a Lincoln Auto Lube system.
