Steel Cable Multi-Layer Winding Grooved Drum For Electric Power Towing Winch

LBS drum is a kind of groove for multi-layer winding of wire rope introduced from abroad. Because of this rope groove in the drum
Most of the circumferential section is kept parallel to the flange end face, only in a very small section and the flange end face intersection,
However, there is a phenomenon of turning, it is named "folding rope groove" too.
Years of practical use has proved that this kind of drum with special rope groove structure can well solve the difficulty of multi-layer winding rope
The double folding cable groove system ensures that the multi-layer winding wire rope on the drum is completely smoothly drawn into and rolled out of the drum.

The towing winch, consists of drum, brake, clutch, wall frame, base, rope arrangement, driving device and the corresponding control device. Its most important role is to connect the tugboat and the object to be towed, and bear the corresponding load load, but also play the role of rope, rope and storage wire rope. The winch is divided into single drum, double drum and multi drum according to the number of drums, according to the power source of electric, hydraulic, diesel engine and steam power, domestic large towing winch is generally driven by hydraulic pressure.

Adopting plate blanking roll cylinder and weld longitudinal welds, checking longitudinal welds and geometric dimensions of cylinder (diameter, length, inner diameter ellipticity tolerance, etc.). For large diameter cylinder, adding welding process reinforcement and machining annular groove of cylinder. There are requirements for the process of roughing the cylinder outside the circle to process the outer circle, cylinder length welding (namely ring seam welding). For the two ends of the cylinder need to add welding process reinforcement according to the process regulations, and check the quality of ring welding and machining allowance, cylinder length processing and both ends of the stop or groove processing and welding cylinder end flange plate, shaft, inner support ring, etc.
