For Fixed Displacement Hydraulic systems

The AJC Hydraulic Generator is a purpose built onboard hydraulic generator solution. The unit is suited to an extensive range of Scissors and Booms that operate with fixed displacement pumps.

All valves incorporated
The manifold incorporates all of the required valves to allow the generator to operate without the need for any other component parts. It incorporates a 12v diverter valve, pressure relief valve and a pressure compensated flow control.

Simple hydraulic connection
To install, simply reconnect the existing pressure line from the function pump into P1, reconnect it back out of P2 and connect a tank return line from T. The unit operates only when the solenoid is energised; this then diverts flow away from the platform functions and through the flow control valve to provide a regulated flow through the gear motor to the alternator. Excess flow is returned to tank. When the solenoid is de-energised flow passes directly into P1 and out of P2 which simply acts as a bypass to the functions.

Electrical connections
The electrical connections involved provide a 12v supply to the coil on the solenoid valve via a toggle switch mounted on the control panel in the basket. In the wiring loom of the platform there is usually an existing circuit to connect this to. For further technical help you should consult either your workshop manual or contact the platform manufacturer for further instructions.

Operator Safety
The AC power cable from the alternator is connected to the RCBO, which is a combined Earth Leakage Circuit Breaker and Miniature Circuit Breaker. This provides protection both to the operator in the event of an earth fault and to the unit in the event of overload. It should be installed as close to the output cable of the alternator as possible in order to ensure that the power cable running through the scissor or boom is protected throughout it’s entire length. The power cable to the basket will then need to be connected into an appropriate electrical socket or sockets mounted on the deck or basket, into which the operator will plug in their tools or equipment.

Mounting the generator
The generator can be mounted in any convenient location, is fully weather proof and can be mounted vertically if required. Units can be supplied in a range of outputs from 2 – 6 kVa, single or three phase, 50 and 60 Hz as well as a range of welder / generators. One of the key advantages of the AJC Hydraulic Generator is that within this range the manifold and valves are common on all units. The units are virtually maintenance free and come with a two year warranty as standard on parts and labour.
