In 2018, a new Control valve lift system was introduced to all models Operation, When system 12v power is turned on power is supplied to energising the Lift Cartridge 2 on the Lift block. In this allows oil into the Lift cylinder in the lifting direction only. Should there be a failure in the lift pressure hose the oil in the cylinder is locked by check valves. To lower the boom, the power is interrupted to the lift cartridge 1 by the Micro switch mounted on the lift section, allowing the oil to return from the lift cylinder. These machines are configured with a flow control cartridge which controls the maximum rate of oil flow from the cylinder. PAGE 1 of 1
