Stainless steel tensioner rewinder is powered by three boxes of non-synchronous motor, through the elastic coupling, through the closed gear reducer box, embedded gear coupling drive reel, using electric hydraulic brake. The product is widely used in construction, water conservancy projects, docks and other materials lifting or flat, as well as modern electrically controlled automatic work line related equipment, its high versatility, compact, small size, light weight, easy to use mobile; for construction, water conservancy projects, docks and other materials lifting or flat, as well as modern electrically controlled automatic work line related equipment. Slip wire trash box this conveyor belt advantage is the use of YZR type coil rotary sub-lifting three-phase non-synchronous motor, equipped with resistance box and controller, its overload capacity becomes large, mechanical strength becomes high, higher safety factor.
