Noise causes huge lift hoist

      lift hoist is powered by a human or mechanical reels, winding traction rope to complete the work of the device. Electric winch consists of motor, couplings, brakes, gear boxes and roll form, mounted on a rack. Can enhance the vertical, horizontal or inclined pulled cited heavy loads. With the widespread use of the day, there have been some problems affecting the efficiency, the process of using the most common problem is the noise problems:

① chassis with box-shaped structure, not all welds are continuous welding, various chassis weld length, height different positions, rigid chassis, there is a big individual differences, and some resonance effect, the machine if it was a little vibration noise Zoom;

      ② from the steel plate welded into the chassis, do not have the shock absorption silencer function if its natural frequency and the gear mesh frequency close to the individual machines may cause weak due to vibration caused by the larger gear total shock, causing noise value rises.

      Hoist lifting height for loading and unloading large work frequently the case, speed performance, make empty hook rapid decline. The installation place or sensitive materials can lower the speed.

1, electric windlass as lifting capacity, speed change is easy, convenient operation and safety, therefore, in the lifting operation is often used as a hoist equipment，
2, more types of electric winch, roll divided by two kinds of monocular and binocular. By way of a reversible drive gear box and friction.
3, slow winch (reversible electric winch), it is simple, safe and reliable lifting heavy objects, but also long-distance operations, is commonly used as a tool for the construction site.
