Lift, Lower and Slew
For smaller systems, cartridge style directional valves provide a compac solution for all of the lift and lower functions. Aditions of relief and brake control pressure reducing valves complete the system.
Load Holding & Control
The safety of the operator is of paramount importance on all man lifts. From the stabilisers to the upper and lower booms, leakage is not acceptable. The overcentres used must provide good load holding, load control, and hose failure protection. The valves used should provide a firm working platform and smooth movement of each operation.
Cartridge overcentre valves can be introduced to stacking valve to give the system designer all of the options available to the integrated circuit designer. Proportional systems can be accommodated using balanced cartridges.
