INTRODUCTIONS

           Building Electric Winches are the most commonly used winches powered by motor. The power is input  into the third level enclosed gear reduction box by flexible coupling to lift weight or pull by wire rope and to drive the drum from low speed shaft end steel key. Common motor and lifting motor are two kinds of motor suitable for different situations. Common motor is used to lift or pull small weight and can be started directly. But when it comes to heavy weight, lifting motor which starts slowly and stably by cam switch and resistance adjusting is adopted.

           Building electric winches are mainly used in lifting, pulling, disassembling, moving and installing loads in construction sites, diggings, water conservancy, marine, shipyard, slipway, forestry, mining and quay places etc. There are two types in this series, large pull capacity and small pull capacity. The former is mostly used in port building, traction of shipyard, steel structure transport and machine pulling. The small pull capacity is suitable for construction, pulling, lifting, traction, assembly and disassembly in construction company, mine, factory and so on. Both JM series electronic control slow speed winch and JK electronic  control high speed winch are available. These building electric winches can pull loads vertically, horizontally or in sloping position.

           The building electric winches are powered by a human or mechanical reel, winding the rope to tow devices. They consist of base, motor, elastic coupling, brake, enclosed  triple-reduction gear box, reel and brackets with electrical control cabinet. The brake system adopts electromagnetic braking or hydraulic braking, so it’s  fast, sensitive, safe and reliable. The steel cable with strong pulling power is orderly arranged and the parts of these wire rope building electric winches are  tenacious. The big capacity of drum rope provides a wide range of choice for the lifting height or pulling length. In addition, remote control is also  optional.

           The work principle of these building electric winches are as follows. First, electric energy is transformed into mechanical energy through the motor and then through the brake. The reducer reduces speed to rotate the reel. Then, the reel winds the wire rope and passes through pulley block, forcing the hook lift the load. At the same time, mechanical energy is transformed into mechanical work finishing transportation, load and unload of weights. 

           The structure of these reasonably designed building electric winches are compact, making them small in volume and light in weight. Apart from their beautiful appearance, these top quality winches also feature convenient operation, small hand pull force and competitive price, so they are popular both at home  and abroad. These building electric winches provide overload protection, shock protection and explosion- proof performance. Besides, their maintenance is very easy.

           They are also called 100% copper motor wire rope building electric winches, Building electric winches for lifting heavy load, Building material lift rope winches, Building electric windlasses, Electric windlass winches for construction building, Building construction electric windlass winches, and Building material lift electric winches.

4.Motor

Motors are applied to drive various hoisting machinery. The motors have big overload capacity and mechanical intensity and are often equipped in short-term or intermittent devices. These motors used in the  building electric winches transfer electric energy into mechanical energy.

6.Brake

These building electric winches adopt electromagnetic braking or hydraulic braking system. These brakes use pullers as their driver units and are mainly used in machine operation equipment of lifting, transportation, metallurgy, mine, port, and building mechanical devices. Their advantages include quick speed, safe  stabilization, low noise, long useful life, electricity saving, high operation efficiency and simple maintenance etc.

3.Announcements
           ①The building electric winches are suitable for use under temperature -10℃~+40℃. If the surrounding temperature is below 0℃, the lubricating oil should be heated up before start-up.
           ②The humidity should be kept below or equal to 85%.
           ③Altitude should be kept below 1000m, and there should be no such accidents as fire or explosion.
           ④These electric winches utilize 380V, 50Hz, 3-phase alternating current power supply and only ±5% voltage difference is tolerable.
           ⑤The working grades are M4 or M5.
           ⑥The rated pull should correspondingly reduce 20% for every working grade increase.
