Application And EnvironmentPictures for reference just due to different model & batch,please contact our sales for confirm.
Dispatching Winch can be used for mine,parking lot of mine,intermediate roadway, mine car for transporting in mining area and driving-head dispatching mine car.It also can be applied to auxiliary handling work on the ground in metallurgical mine construction site.
The main components of Dispatching Winch： Motors, Drums, Planetary Gears, Brakes devices and Base
The reduction gears of braking belongs to two-speed planetary gears, Gear coupler is applied to connect motor shaft and high-speed rotating solar wheel axles and the internal support of winch is rolling bearings.
(1)Ambient temperature being -10 ℃ ~ +40 ℃; Ambient humidity no more than 95% (+25 ℃); Altitude below 2000 meters.
(2)The methane, coal dust, hydrogen sulfide and carbon dioxide in the surrounding air no exceed the safety level stipulated in "Coal Mine Safety Regulations"

Working PrinciplePictures for reference just due to different model & batch,please contact our sales for confirm.
The motor gear drives
a pair of pinion gears on the left
pinion carrier to rotate. Concerning
that the internal gear on the left end is fixed, therefore, along with the autoroatation,
asteroid gears have to orbit around
motor gear. At this time,
there are three conditionse:
If the left brake has been released, the internal gear will be braked by the right brake. At this moment, the large planetary gear will revolve around the solar gear while autorotating, meantime, the large gear carrier is also driven to rotate.
The state of rest refers to the roller stopping rotating makes the heavy chant stays at a certain position when right brake is released and the roller is braked by the left brake.
Releasing both the left brake and right brake will lead heavy chant to fall down freely and the roller to reverse.devices should be alternately braked or released.
Main StructurePictures for reference just due to different model & batch,please contact our sales for confirm.
Components of Dispatching Winch：Motor, Reel device,left and right brackets, brakes and machine base
The winch structurally employs bipolar planetary gear to be rotated, which are arranged on both ends of the spindle respectively The spindle runs through the roller, The left end is supported by the left bracket and the right end is supported by the right bracket，he motor is fixed on the left bracket by flange.
The Roller Of Dispatching Winch
There are three main functions of the reel device，the first one is winding the wire rope to tow and drop the heavy goods. The second one is slowing down the speed through planetary reduction gear of reel lumen.The third one is the brakes installed on the brake disc play a role in controlling the reel rotation or stalling. The entire reel lumen is compact and flexible. The distance from the edge of the drum to the outermost winding layer of the rope should not be less than 2.5 times of the diameter of the rope.
Base Of Dispatching Winch
Base is the welding structure and the winch base is welded by the steel. The motor bracket, bearing bracket are fixed with bolt one the both ends of the base. The different thickness of steel plate will be adopted according to different force.
The Brakes Of Dispatching Winch
Dispatching winch has two brakes with the same strucure, which is fixed above the base with brackets. Normally the left brake controls the rotation and stopping of the reel. and the right brake mounted on the other brake wheel acts as a clutch（Figure A）.When the brake wheel is braked, the reel will enter the working state of pulling heavy objects. Left brake device also has the role of safety brake. When the winch power, overload, or other causes of current increases, the winch mounted magnetic starter current limiting thermal relay device will automatically cut off winch power resorce, the left brake device will be an emergency brake, which played To the purpose of safety brake. The material of brake is asbestos. Asbestos brake uses rivets to fasten to the brakes. When braking,the winch will be stopped by simply pulling the handle let the brake blet to tighly hold the reel or brake wheel.
1、The friction performance of brak pad in barking device should meet the following requirements：
a.In the friction test, flame-burning and no flame-free combustion should not occur
and explosion should not be caused in the closed flameproof box.
b.In the friction test, the temperature of specimen and test disk surface
should not exceed 150 ℃.
2、Rivets should be made of copper or stainless steel materials, countersunk hole
depth should be 2-3mm。
3、Non-metallic materials used in the performance requirements should be consistent with MT113-1995 flame retardant anti-static provisions
In working condition
Strictly prohibited braking the left brake and right brake at the same time.
1.The operating mechanism of winch should be flexible and reliable,easy to operate and safety.
2.Each seal parts of winch not have oil spills.
3.Winch operation should be smooth and no abnormal sound and vibration.
4.Before assembly, all parts (including purchased parts, standard parts) must be tested and qualified to be used.
5.The parts should be cleaned in a cleaning environment.
6.The maximum oil temperature during winch operation should not exceed 80 ℃.
7.The brake contact area of winch brake should not be less than 80%.
8.The parts are coated with phenolic primer，the body of machine should be painted according to the requirements of the contract, paint appearance is supposed to be smooth,complete without the defects of brush marks peeling, accumulation and blistering and so on. The adhesion of paint will be checked with grid and coating on the edge of the grid or incision at the cross is not allowed to be dislodged or part dislodged,the dislodged area should not be more than 15%.

Preparation Before Installation
Before installaltion, the situation of installation site ought to be checked firstly, which should be smooth,spacious,and easy to operate and observe.
The Installment Of Dispatching Winch
The reel should be centered on the pulley or hook，this centerline is intended to be perpendicular to the winch axis.
When the using place of winch usually change, fix the winch on a wooden board or channel, Anchor fixed again,long-term fixed-point using winch can be installed on the concrete foundation. Winch installation must be stable and reliable,the base should not have significant vibration during normal operation of the winch.
