How to solve the problem of cargo lifter rope quit
Division I briefly explain how to solve the problem then quit rope cargo lifter?
A hoisting cargo lifter as maintenance, management, and other reasons, there was a rope jump ship accidents. The device is rated load 2t, rated speed of 0.25m / s, a total of five ropes on the traction sheave diameter of 13mm, manufacture date is February 2006. Since the device using high frequency, load, operating personnel and undocumented employment, poor management system, maintenance units do not maintenance in place, these are incidents of potential problems. Inspection of the equipment, it was found off the rope grooves serious phenomenon.
     In recent years, more and more cargo lifter assembly line for the carriage of goods, the principle of its structure and function is very similar to freight elevators. Difference between the two lies in cargo lifter for cargo carrying capacity is large and can not be manned, the car is no manipulation of the button, the safety device is relatively simple, the poor quality of the various mechanical parts, its only downside governor overspeed protection. Precisely because of its relative simplicity and safety devices of poor quality parts, running load is larger, its probability of an accident is higher.
Hydraulic cargo lift performance characteristics and uses
Sets of cylinder cargo lifter is a versatile high-altitude operating machinery, its function will contain the operating personnel and the use of equipment for aerial platform to the height specified in special operations engineering equipment. This equipment is widely used in mining plants, tall hall, warehouses, railway stations, squares and other high-altitude operations. Machine by the platform, telescopic electrics tacker, single or dual ladder ladder anti-rotation mechanism, chassis fuel tank, legs, walking round and so on. Platform telescopic cylinder direct lifting, when you start the motor, the motor driven gear pump oil, the oil through the check valve and solenoid channel input cylinders, telescopic cylinders is increased by section, when the platform rose to a maximum height, the system pressure rated working pressure is reached, then there is oil unloading valves, hydraulic maintained at a constant working pressure, the check valve holding pressure after the shutdown, the platform will remain at the maximum working position, platform height according to the site's operations maximum height of any of the following locations.
