Electric Winches

Electric winches is used to complete traction drive with human power or mechanical power via a reel, which can handle heavy materials or loads vertically or horizontally or obliquely. The electric winches has the features, such as, generality, compact structure with small volume, light dead weight, large lifting capacity and convenient to move, etc.mx9Henan Dongqi Machinery Co., Ltd

Components of Electric Winches

An electric winch is usually consisted of the following components: coupling, brake, gear box, reel, all of which are installed on the machine frame for material handling. Electric winch has a good speed regulation which can lift heavy loads up to a high place at relative fast speed and make an empty hook down swiftly while for sensitive materials, the electric winches can run at a relatively slow speed.mx9Henan Dongqi Machinery Co., Ltd

 Work principle of Electric Winches

How does the electric winch work? Generally, electric winches transform electric power into mechanical power through motor, where the rotor of motor runs and produces the power which is outputted and then goes through the brake, and the reducer reduces the speed to rotate the reel. The reel winds the wire rope and passes through pulley block to make the hook lift the load, and transforms mechanical energy into mechanical work for material handling, such as, the transportation, load and unload of heavy weights.mx9Henan Dongqi Machinery Co., Ltd

Electric Winches Classifications and Features

Electric winches can be grouped into various types, such as, JM Series electronic controlling slow speed winch, JK series electronic control high speed winch, JMM friction series winches, JK-D series winch and IKL series hand control high speed free rolling winch. Each type of electric winch has its own features and advantages, which can find their places in the various applications and performsmx9Henan Dongqi Machinery Co., Ltd

How to use electric winches safely

Before the electric winches start working, in addition to comply with the winch safety operation, it should be test run, inspect every parts and familiar with the operation situation. Here is some instructions:mx9Henan Dongqi Machinery Co., Ltd

  1. The anchor bolts will be fixed or embedded anchor when the winch is installed. To avoid dragging the electric winch when working.
  2. Before using the electric winch, check all the parts carefully and whether the bolts loose, wire rope fastening degree and the lubrication conditions to every part, etc.
  3. The electric winch needs to be no-load test run for 15 minutes before working. Check each transmission part to make sure it has no shock vibration phenomenon, and the switches is sensitive, and the brake is flexible and reliable.
  4. Overload is absolutely forbidden during operation. The lifting capacity of electric winches is in the technical parameters range.
  5.  Dynamic load test is exceed 10% of rated load of electric winch, repeatedly lifting several times. After testing, check whether the electric winch’s mechanical transmission, electric parts and connect parts are normal and reliable.
  6.  During operation, prohibit cleaning or refueling, no person stand in front of the machine or under the heavy objects. Also notice the transmission performance of machine, to keep the transmission parts lubricated well.
  7. During operation, the operator should pay attention to the unfavorable conditions of wire rope on the drum at any time, and clean them in time. Strictly prohibit to use the hand to guide the wire rope.
  8. Electric winches should be operated by specialist, and inspect and maintain it regularly to avoid the damage caused by improper using. If find it out of order during working, the main power should be cut off immediately.
  9.  When electric winches is not  working, the heavy object is not allowed to suspend in the air. The main power source should be turned off after working.
  10.  Gear reducer oil level should keep above the oil level elevation line, reducer adopted 55-7 oil for lubrication. Change the oil every 2-3 months. And other lubrication parts refuel 2-4 times every shift.
  11.  After half year’s working, inspect the reducer and change the lubrication oil, inspect the brake, motor and test the motor’s insulation resistance to ensure safety production.mx9Henan Dongqi Machinery Co., Ltd
