The Three Common Problems with Hydraulic Winches

　　When it comes to hydraulic winches, most people probably know that they’re primarily used for applications involving relatively large rated loads—typically, winches ranging from 10 tons and up to 5,000 tons are designed as hydraulic winches. But are you familiar with the common issues that often arise with hydraulic winches? Today, let’s take a look at the three most frequent problems encountered with hydraulic winches!

　　I. The signaling system of the hydraulic winch

　　The operation of the hydraulic winch is primarily guided by signals transmitted from the signal operator. If the signal operator fails to send a signal, the interlock system will lock the operating circuit, causing the winch operator’s control lever to become jammed during operation. As a result, the axial piston pump will be unable to deliver high-pressure hydraulic oil, and the motor will fail to rotate. However, since the disc-type brake has already been released, the drum will continue to rotate under the influence of gravity, thereby leading to an accident.

　　II. The hydraulic winch cannot determine the position simultaneously.

　　Although it is often mentioned when using a winch that it can lift both people and objects simultaneously, it cannot accurately pinpoint the location, which leaves potential safety hazards.

　　3. Cooling System for Hydraulic Winches

　　In daily operations, hydraulic winches often alternate between working and stopping. If the cooling water cannot be shut off precisely, it results in significant water wastage, and the need to drain this water further increases the mine’s drainage volume.

　　So those are the three most common problems with hydraulic winches—do you understand them? As modern technology continues to advance, the manufacturing of hydraulic winches will surely improve gradually, reducing the occurrence of these accidents.
