HYDRAULIC DIAGRAM FOR OPEN CIRCUIT OR IN-LOAD TESTING OF THE ROPE HOIST

摘要

the invention refers to a hydraulic scheme for the pit produced in empty and load cable what wrap trolls in orderly manner, in multiple layers on the hoist drum.the tension in the cable may be modulated by desire and maintained automatically at the value imposed. there is a possibility the permanent control of machines indicated or recorders of tension in the cable.the scheme can be dimensiona stand, respectively, for a wide range of powers, respectively, tension in the cable. energy use for the task is reduced.
