500kg 1 Ton 3 Ton Electric Trolley Type Electric Chain Hoist

500kg 1 ton 3 ton Electric Trolley Type Electric Chain Hoist is a kind of light and small lifting equipment with smaller volume and lighter weight than wire rope electric hoist. It is widely used in factories, docks, warehouses and other production sites.

It comes with an electric sports car, which can walk left and right on the I-beam, generally in four directions, up and down, left and right, and can be used in six directions (up, down, left, right, front and rear). The electric trolley is equipped with a guide wheel device to make the hoist run more smoothly on the I-beam.

It is composed of a motor, a transmission mechanism and a sprocket. The difference from the electric wire rope hoist is that the wire rope is replaced by a chain, which makes up for the large and bulky shortcomings of the electric wire rope hoist. The lifting weight is generally 0.5t-35t, and the lifting height is 3-120m.

3. Component:

Motor: There is a thermal protection device to prevent the motor from being burned out due to overheating.

Brake: The mechanical brake is used, and the copper wire asbestos-based friction material is clamped. Once the motor stops, the brake can support the load stably. Reducer: used to reduce speed, increase torque, and transmit power.

Limit switch: The upper and lower electronic limit switches are used to prevent the chain from being over-tightened.

Torque limiter: It can make the motor idling when overloaded or over-tightened to prevent damage to the motor and mechanical transmission system due to overload or over-tightening.

Hook and chain: The hook is forged from alloy steel and undergoes a strict heat treatment process. It will not break when overloaded, but will only open slowly. After heat treatment, the chain has good wear resistance, good corrosion resistance and long service life.

3. The difference between electric chain hoist and electric wire rope hoist:

(1) The transmission medium is different

The transmission medium of electric wire rope hoist is wire rope. The wire rope has a large bearing capacity. It is usually used to lift heavy tonnage. After a period of use, it will cause certain wear and tear, and the operation is difficult, and the utilization rate of the equipment is gradually decreasing.

The transmission medium of the electric chain hoist is a chain, which is flexible and convenient to operate, has a fast lifting speed, and is widely used in equipment.

(2) The operating conditions are very different

Electric wire rope hoists are relatively slow in terms of starting speed and other aspects of operation, because the wire rope needs a long length during operation, occupies a large space, and starts slowly.

However, the electric chain hoist runs faster and starts faster, the equipment is light and flexible, and the space occupied during the operation is relatively small.

(3) Different application environments

The electric wire rope hoist has a large carrying capacity, and the equipment is usually used in large-scale lifting and hoisting occasions such as bridges, buildings, and steel plants.

The electric chain hoist has a fast lifting speed, and the equipment is usually used in cargo terminals, docks, warehouses and other occasions, which can quickly and efficiently carry out heavy lifting operations.

4. Applicable Environment:

500kg 1 ton 3 ton Electric Trolley Type Electric Chain Hoists are widely used in workshops, warehouses, wind power generation, logistics, docks, construction and other occasions.

It can also be used in conjunction with single and double beam cranes, cantilever cranes and gantry frames. It can be used for lifting or loading and unloading goods, and can also be used for installation, debugging and maintenance of precision molds.

The operator can follow the operation on the ground with the button, and can also operate in the control room or use wired (wireless) remote control.

5. How to operate?

Both electric chain hoists and electric wire rope hoists are small lifting equipment, and they are almost the same in terms of operation methods.

7. Use and maintenance of electric chain hoist

(1) The electric hoist that is newly installed or installed after dismantling and inspection should be tested for several times first.

But before the installation is completed, do not try to turn on the power.

(2) The electric chain hoist should be subjected to a static load test of 125% of the rated load, about 100 mm above the ground, and 10 minutes before normal use, and check whether it is normal.

(3) The dynamic load test is to perform repeated lifting and left-right movement tests with the rated load weight. After the test, check whether the mechanical transmission parts, electrical parts and connecting parts are normal and reliable.

(4) In use, it is absolutely forbidden to use it in an environment that is not allowed, and when the rated load and the rated closing times per hour (120 times) are exceeded.

(5) During installation, debugging and maintenance, it is necessary to strictly check whether the limit device is flexible and reliable. When the hook rises to the upper limit position, the distance between the hook shell and the drum shell must be greater than 50mm (10t, 16t, 20t must be greater than 120mm) .

When the hook is lowered to the lower limit position, the safety circle of the wire rope on the drum should be ensured, and the effective safety circle must be more than 2 circles.

(6) It is not allowed to press two flashlight door buttons that make the electric chain hoist move in opposite directions at the same time.

(7) After the work is completed, the main gate of the power supply must be opened to cut off the power supply.

(8) The electric chain hoist should be operated by a special person, and the operator should fully grasp the safety operation rules, and it is strictly forbidden to slant the hoist.

(9) The electric chain hoist must be inspected regularly by specialized personnel during use, and measures should be taken in time if any faults are found, and they should be carefully recorded.

(10) When adjusting the braking slippage of the electric chain hoist, it should be ensured that under the rated load, the braking slippage S≤V/100 (V is the distance that the load can lift steadily in the next minute).
