Description
technical field [0001] The invention relates to a hydraulic elevator system with heavy load and high speed, which belongs to the technical field of elevators. Background technique [0002] Hydraulic elevators quickly seized a part of the domestic market with its advantages of flexible room layout, safety, reliability, and convenient maintenance. As the height of high-rise buildings is getting higher and higher, the requirements for the load capacity and speed of elevators are also getting higher and higher. However, the oil pressure of the oil circuit system of the existing hydraulic elevators is generally not high, resulting in the poor performance of the existing hydraulic elevators in terms of load capacity and speed, so they can only be used in low-rise buildings. Contents of the invention [0003] The object of the present invention is to provide a hydraulic elevator system with heavy load and high speed. The invention can greatly increase the pressure of the oil ci...
