The

Hydraulic Pump actuates the Cylinders which operates the Fork and tilting of the vertical frame The Frame can be tilted forward by 3 to 5 degrees for simplifying the load gripping and can be tilted backward by 10 The nonnal speed ofthe Fork Lift Truck is 7 5 km hr when there is no load and can be 6 5 kmIhr when loaded The maximum possible lift ofthe Fork is nonnally 2 75 m and the weight carrying capacity is nonnally the

o

restricted

to within 2 5 to 3 tonnes

The operation ofthe Fork Lift is very with the normal

simple and the driver shallbe familiar procedures including tbe steering mechanism
