Replace with the oil, whose viscosity is
compatible with the running temperature of
pump.
4.5 Lifting system
The lifting system is composed of the inner & outer mast, sliding bracket, pallet fork, rolling bearing and
sprocket set.
4.5.1 Inner/outer mast (Fig.4-18)
Connect the frame through two bearing seats at the bottom of outer mast and the middle part to the frame
through the tilt cylinder. In operation, the free lifting amount of pallet fork FE10 and 13 are 85mm, FE16, 18
and 20 are90mm. Adjustment method of system: ① Adjust the tilt cylinder to have the mast lean forward 6°,
and backward 6.5°. The tilting forward and backward of twin-cylinders are synchronized; ② Set the mast
perpendicular, let the pallet fork lower on the ground. Adjust the lifting chain to ensure that the pallet fork
touches the ground. Adjust the lifting chain, to ensure that the center of lower roller under the pallet fork
bracket keeps the distance of 15~20mm away from the lower edge of inner mast and enable two chains to have
same tensioning force; ③ Adjust the synchronization between the L/R lifting cylinders.
