Top sale Stationary or fixed type Single lifting speed or double lifting speed Metallurgical wire rope electric hoist

Product introduction:

The metallurgical electric hoist can be installed on the I-beam track to lift heavy objects, and it can reciprocate in a straight line and a curve along the track to ensure sufficient safety. Molten metal can be lifted, but it is forbidden to use it in a low temperature below -10°C or an environment above 50°C. It is suitable for working in an environment without fire, explosion hazard and corrosive medium.

The metallurgical electric hoist drum is made of cast steel or seamless steel pipe. Power is transmitted by splines, and the drum shell is welded by steel plate. The drum device is the central part of the hoist. The upper part is connected with the trolley running mechanism, and the lower part is connected with the hook device through the wire rope. The upper part of the outer cover

Technical parameters：

Mechanical Parts:

1) The metallurgical electric hoist is composed of several parts that can be disassembled separately, mainly composed of four parts, one is the lifting mechanism; the second is the operating mechanism; the third is the control device; the fourth is the second braking device; use and maintenance And inspection is very convenient, and can shorten the maintenance cycle;

(2) The motor adopts the YZD series cone-rotor three-phase asynchronous motor, the protection level is IP44, the motor insulation level is H level, and the motor cone brake is used as the supporting brake; the lifting mechanism is additionally equipped with a safety brake;

(3) A high-temperature heat insulation protection function is set under the electric hoist, which effectively avoids direct heat radiation;

(4) The steel wire rope adopts steel core steel wire rope, which has the characteristics of high temperature resistance;

(5) The lifting mechanism is equipped with an overload limiter. When the lifting capacity reaches 95% of the rated lifting capacity, the overload limiter sends out an alarm signal. When the lifting capacity reaches 105% of the rated lifting capacity, the lifting control circuit is disconnected and the lifting contact When the motor is released, the motor stops rotating after power failure;

(6) The hoisting mechanism realizes double protection of ascending limit, the first level of protection is the fire limit protection, and the second level of protection is the trip control protection;

(7) The electrical components of the control box adopt Chint contactor, and the protection level of the control box is IP44;

(8) The reducer adopts standard modular cylindrical gears, which is convenient for maintenance.

(9) The parts are widely used and interchangeable.

Safety System:

1. The working level of this electric hoist is M6, and the working environment temperature is not higher than 60℃.

2. The lifting mechanism is equipped with two supporting brakes and one safety brake. The first stage is the magnetic pull brake of the cone rotor motor, that is, the working brake. The second stage is the friction dry head brake installed at the input of the reducer to prevent the failure of the first stage brake and continue to make the load rise and fall normally. move. The safety brake is a safety brake emergency braking device installed on the reel assembly to prevent the mechanism from failing and the transmission device is damaged in an emergency state.

3. Secondary limit device for upper limit position. The first time is the conventional electric hoist up and down travel limiter limit, and the second time is the heavy sag limit.

4. Thermal radiation protection of the main engine, the whole machine is equipped with a heat insulation board under the shell of the electric hoist drum, and two metal sheets are used to sandwich high-temperature asbestos materials to isolate the high-temperature radiation of the molten metal.

5. The insulation grade of the hoisting motor and the running motor is H-class, and the hoisting motor winding is equipped with an overheating protection device.

6. The steel wire rope adopts 6×37S+IWR-GB8918-2006 high-strength high-temperature resistant steel wire rope for important purposes.

7. The electrical control device is equipped with zero-voltage protection, loss-of-voltage protection, and over-current protection with phase-out protection. The control equipment cable adopts ZR+-YCP combustible heavy-duty rubber cable.

8. The control method adopts remote control or centralized control
