Price picture of small and medium-sized hydraulic motor winch

  When the winch implements free lowering operation, the reversing valve of the winch is in the middle position, connect the external control oil circuit, release the brake, open the hydraulic control one-way valve, connect the oil inlet and outlet of the hydraulic motor, and realize the free lowering action of the winch under the action of load
This kind of winch has simpler structure than the winch with clutch free lowering, and is widely used in hydraulic core drilling rig
The winch is composed of various valve blocks, hydraulic motors, multi piece hydraulic brakes, planetary reducer, drum, frame and other components with one-way or two-way balance valve and high-pressure shuttle valve for controlling hydraulic brake
Users only need to be equipped with pump station and directional valve
Because the winch has its own valve group, it not only simplifies the hydraulic system, but also improves the reliability of the transmission device
Hydraulic winch is actually a kind of lifting device, and there are many kinds of it
According to the speed, it can be divided into low-speed hydraulic winch, medium speed hydraulic winch and high-speed hydraulic winch
The internal device parts of each type of hydraulic winch can be adjusted and changed according to the needs of users
This kind of machinery and facilities are generally used in various needs
It has the function of free lowering and the hydraulic principle of hydraulic winch
An external control oil circuit is added to the hydraulic winch to control the brake and hydraulic control one-way valve
Users only need to be equipped with pump station and directional valve
Since the winch has its own valve group, it not only simplifies the hydraulic system, but also improves the reliability of the transmission device
It is used for large lifting equipment, such as oil drilling rig, offshore oil drilling platform, rotary drilling rig of piling machinery, rock drilling rig, core drilling rig, hydrostatic pile press, etc
