Abstract

The novel stepped hydraulic lift includes at least two hydraulic cylinders set on the bearing cage and at least two set of supports fitting the hydraulic cylinders, and the supports, guide tracks and power supply wires are set around the passage. It is superior owing to its stepped mode resulting in great elevation height with short stroke hydraulic cylinders and increased bearing capacity, and double channel and one-way network loop motion mode resulting in fast speed and great transport amount. It is suitable especially for high rise building and is safe, simple in structure and reliable, and has many other advantages.

Description

technical field

[0001] The present invention relates to a new hydraulic elevator, especially a step-type hydraulic elevator. Background technique

[0002] The hydraulic elevators currently in use are mainly lifted by the use of sleeves, which have the advantages of large lifting capacity and so on. However, there are also disadvantages such as low lifting height, about 25 meters, the thrust provided by the primary and final stages of the sleeve is quite different, the installation occupies a large area, one elevator occupies one passage, and the capacity is limited. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide a step-type hydraulic elevator that utilizes a short-stroke hydraulic cylinder for long-distance and large-height lifting. Another object is to provide a multi-channel fast and large-capacity stepping hydraulic elevator.

[0004] The solution of the present invention is: set the ent...
