Lift Lower blocks are a compact hydraulic solution to control single acting cylinders that are generally mounted on stackers and scissor lifts. They offer a complete solution for lifting, controlled lowering and safety of the pump, cylinder and personnel.

When the pump is switched on, the oil from the pump extends the cylinder. After full extension, the Check Valve (1) holds the load in place at which point the pump can be switched off. To lower the valve, the Solenoid Valve (3) is energized which opens the flow of oil to tank. The rate of lowering is adjusted by means of a Flow Control Valve (3). There is an inbuilt Relief Valve (4) for pump protection in case of a rise in pressure.

The system is mounted on the framework of the stacker/scissor lift itself. The compact nature of the hydraulic system reduces the need for bulky valves and piping. Solenoid valves are available with a manual over-ride function to lower the platform in case of power failure. Due to the load holding nature of the system, there is no need for the pump to offer continuous duty and hence there is reduced power consumption.
