Abstract
The invention relates to a hydraulic lifter comprising a base, a lifting mechanism, a working platform and an electrohydraulic controlling mechanism. The lifting mechanism is provided with a multistage telescopic oil cylinder; the working platform is arranged on the top of the lifting mechanism; and the electrohydraulic controlling mechanism is used for driving the lifting mechanism. The hydrauliclifter is characterized in that the base is provided with a balancing device used for keeping the base horizontal; the balancing device comprises at least three base balancing oil cylinders which arefixed on the balancing device; the sleeves of the base balancing oil cylinders are fixedly arranged on the base; and piston rods of the base balancing oil cylinders are arranged towards the ground. The balancing device can be in two working states. When the balancing device is in the first working state, the piston rods of all the base balancing oil cylinders tough the ground, and the base leavesthe ground. When the balancing device is in the second working state, the base touches the ground, and the piston rods of all the base balancing oil cylinders are folded in the sleeves of the base balancing oil cylinders. Because the base balancing oil cylinders of the invention can support the base, the unbalanced loading of the hydraulic lifter, which is resulted from the uneven construction ground, can be avoided.
