This series product winch structure type has the characteristics of compact, light weight, very light, beautiful and generous appearance design, and has the characteristics of good safety factor, high efficiency, large starting torque, good reliability of low speed, low noise, reliable practical operation, etc.. Application scope:

1. Rescue and road clearance;

2. Construction machinery; 3. Mining machinery; 4. Forestry division;

5. Oil industry

Four reasons for insufficient working pressure of mining winch

1. The oil pump is too hot for many times.

Causes: (1) Oil pump damage or damage; ② The viscosity of oil is too low;

Methods: (1) Maintenance or replacement; (2) Mining winch manufacturers should apply gear oil with highly recommended viscosity.

2. The oil pump is not converted correctly.

Cause: Wiring of electrical equipment is incorrect;

Method: Correct the rotation direction of the oil pump.

3. The oil pump speed ratio is too low.

Cause: the motor has common faults;

Mode: Common faults.

4, vertical hoist hydraulic pump from the high pressure side to pump oil leakage or hydraulic oil can not be all normal basis.

Causes:

(1) The exhaust pipe of pneumatic drawworks overflow valve is not sufficient;

(2) The proportion of the overflow valve is not closed, there are dirty things or damaged parts;

③ There are dirty things or damaged parts in the electro-hydraulic directional valve;

(4) The spool of the direct action relief valve is stuck or damaged by dirt;

⑤ The pressure regulating valve spool is stuck or damaged by dirt.
