Product introduction
MD1 wire rope electric hoist is one of wire rope electric hoist, is also a two-speed electric hoist. The product can be used with electric hoist trolley, so it is more convenient to operate. It has the characteristics of light weight, simple structure, novel form, stable operation and so on. It can cut off the main circuit in an emergency, and has up-stroke and down-stroke protection of the position of the fire-breaking limiter. To ensure the safe operation of electric hoist. Long service life and more reliable use of electrical components. GB1102-74[6 * 37 + 1] type lifting wire rope is adopted to ensure durability and durability. And there are rope control and cordless remote control of two ways.
Performance characteristics
t is suitable for working in the environment of temperature-20 ° C-40 ° C, relative humidity ≤85% , altitude below 1000m, without fire, danger and corrosive medium. It is forbidden to transfer molten metal and inflammable articles. The applicable power supply is AC three-phase, 50Hz, 380V. The work type of this product is intermediate. The rated lifting capacity must be reduced by 20% for each level of working level.
How it works
MD1 electric hoist than CD1 electric hoist more than a lifting auxiliary motor. The lifting main motor and the lifting auxiliary motor are both conical rotor motors with tapered brakes. The combination of the two motors consists of a slow driving device, which comprises a pinion gear (connected with the lifting auxiliary motor) , middle Gear and in gear (connected to the brake block of the lifting main motor) . When the electric hoist is to work at a slow speed, make the hoisting auxiliary motor work. It rotates the rotor of the hoisting main motor through the small gears, the middle gears and the big gears. It drives the drum to rotate through the coupling system and the reducer system, wind the wire rope to raise and lower the hook. When the electric hoist is working at normal speed, the lifting auxiliary motor is not energized and is in the braking state. At this time, the lifting main motor is energized and the reducer and reel are driven through the coupling system. When the electricity is not energized, the lifting main motor and the auxiliary motor are in the braking state, the hoist can not work.
