Electric cable hoists and electric wire rope hoists application

• Our traveling electric hoists can be installed on various kinds of cranes or suspended on I-beam to do some straight or curve motions.
• Fixed electric hoists can be installed on fixed support to do some vertical motions.
• Wire rope electric hoist are widely used in industrial workshop, mining, rail way, port, and warehouse sites, etc.

Working conditions of electric cable hoists and electric wire rope hoists application

Wire rope electric hoist is widely used in the temperature of -25℃～+40℃, Humidity≤85%, Altitude below 1000m. The power of the wire rope electric hoist is generally 3 phase 380v 50 HZ, which also can be customized.

 Electric cable hoists and electric wire rope hoists classification

Single speed CD electric wire rope hoists, double speed wire rope hoists, explosion-proof, metallurgic wire rope hoists, and low head room wire rope hoists, etc.

Structure layout of electric cable hoists and electric wire rope hoists

The electric hoist is composed of lifting mechanism, traveling mechanism except fixed type electric hoist, and electric parts. The structure of electric hoist is shown in the following drawing:

 

 Features of electric cable hoists and electric wire rope hoists

1. Lifting mechanism of electric cable hoists and electric wire rope hoists

In order to make wire rope of drum drive the hook up and down, the lifting motor of the rope hoist drives winding drum to rotate through coupling and hollow spindle of reducer.

2. Lifting motor of electric cable hoists and electric wire rope hoists

1. Tapered rotor three-phase asynchronous braking motors.
2. High starting torque, effective braking, compact structure
3. Stable operation, small volume and light weight
4. Safety in use, convenient maintain
5. B or F class insulation, IP44, IP54 protection

As for single speed electric hoist, the motor used is CD1 type motor while the double speed electric hoist uses MD1 type motor with the ratio of usual speed and low speed is 10:1.

3. Reducer of electric cable hoists and electric wire rope hoists

1. Three-level dead axle helical gear rotating body, long service life.
2. High quality and high intensity gear and axle, made by alloy steel after heat treatment.
3. Box and cover made from superior cast iron, fully covered.
4. Compact structure, silent operation, high efficiency
5. Machinery oils
6. Easily assemble and disassemble.

4. Rope drum of electric cable hoists and electric wire rope hoists

1. Rope drum is made of cast iron or seamless steel tube, light weight, transmit the dynamic force by splines.
2. Coil casing made from superior cast iron, high intensity.
3. As the central part of hoist, the rope drum is connected with traveling mechanism through balance beam, with reduce and motor both sides, and with wire rope and hook below.
4. Limited guide bar is installed to the upfront of the outer cover.

5. Hook of electric cable hoists and electric wire rope hoists

1. Hook of rope hoist is made of forged steel, thrust ball bearing connect with casing through hook and beam to make the hook operate freely.
2. Above 5 ton: single pulley hook; above 10ton: double pulley hook,
3. High security, safety buckle, and mousing hook.

6. Travelling mechanism of electric cable hoists and electric wire rope hoists

The traveling mechanism of wire rope hoist is consisted of electric trolley, travelling reducer, travelling motor, driven trolley, etc. The mechanism do reciprocating motion through main engine driven by side plate and drum.

   7. Features of wire rope hoist traveling mechanism

1. Wheel tread is straight when used on box girder or H beam and it could be circular arc when used with I-beam.
2. Traveling speed is 20 m/ min, however 30 m/min is also possible.
3. If 1-5 ton capacity with 12m or higher lifting height, a driven trolley is necessary.

   8. Electrical device of electric cable hoists and electric wire rope hoists

1. Control box is rational layout, convenient for maintain.
2. Protection grade of control box is IP55 which is also water-proof.
3. The main power source is optional.
4. Safe touch line has high electrical conduction and low pressure.
5. Current collector has high planning speed to ensure the sustaining power supply.
6. Switch button power voltage is 380v or 36v, standard product is 360v.

 9. Safe and standard protecting function of electric cable hoists and electric wire rope hoists

1. Multiple safety measures and protections are adopted: voltage protection, ground protection, short-circuit protection, thermal protection, overload protection, limit protection, and power-off protection.
2. Lifting limiter: broken fire limit device during up and down travelling.
3. Overloading protection: Overload limiter, customized according to application condition.
4. Top-clashing proof device: heavy punch limiter, sensitive reaction, compact appearance.
