7.Lifting system
Lifting mechanism consists of 4 major parts: walking mechanism, hydraulic mechanism, electric control mechanism, support mechanism. Hydraulic oil from the vane pump to form a certain pressure, through the oil filter, explosion-proof electromagnetic reversing valve into the lower end of the liquid cylinder, so that the piston of the liquid cylinder upward movement, lifting the weight; hydraulic oil through the explosion-proof electromagnetic reversing valve into the upper end of the liquid cylinder, the lower end of the liquid cylinder back to the oil tank through the balance valve, liquid-controlled check valve and other reversing valve, so that the weight down smoothly.
