Introduce of double drum winch
Double drum winch, simply speaking, it is no need the electricity, diesel engine, which can be divided into two type, single drum and double drum, the double drum winch can realize towing in two directions, the towing capacity and towing distance can be customized as per the true demand, what's more, the rope arranger can be equipped if needed.
Maintenance of double drum winch
The maintenance of the machinery is not interrupted. The hoist is regularly maintained and maintained. The inspection and maintenance measures are carried out over a period of time. The damaged parts and some of the more easily damaged parts are promptly replaced. Proper maintenance can be avoided. The process of running brings unnecessary trouble for yourself.
Important parts of the winch should be observed and inspected at any time, such as brakes, clutches, stoppers and other vital parts. Pay attention to their operating conditions and damage, and clear away the faults.
If the hoist has not been operated for a long time after it has stopped for a long time, an inspection and maintenance measure shall be carried out again when it is used again. During the period when the hoist is disabled, it shall be placed in a ventilated and dry place for better maintenance so as to prevent moisture and corrosion.
During the assembly and disassembly process of the winch, attention should be paid to the surface of the hoisting machine. Check the wear condition of the friction surface, the condition of the gears and bearings of each department, the wear of the rotating parts and the coupling parts, and the condition of the electrical components. If the machine is affected, it should be replaced in time.
When the 30KW electric rake winch for coal mines is used to rake the mine underground, the temporary fixing method is generally adopted, and there is no permanent fixed foundation. The fixing must be firm, and the fixing pile of the machine must be checked frequently for signs of loosening. Any problems should be dealt with in time to ensure the safe operation of the equipment.
