Explosion Proof Electric Wire Rope Hoist Common Questions

BCD type explosion-proof electric hoist is a "explosion-proof" hoist, explosion-proof level has 3 levels of explosion-proof, 4 levels of explosion-proof. Generally used in places with flammable and explosive gas such as hydrogen, natural gas, etc.

According to the usage mode, it can be divided into mine, chemical, and factory explosion-proof hoist, and the appropriate explosion-proof wire rope electric hoist can also be selected according to the actual working conditions of dust.

Explosion-proof Electric Wire Rope Hoist Explosion-proof Principle

Explosion-proof electric hoist is a complete set of electromechanical equipment composed of explosion-proof electrical equipment, metal structures, mechanisms and parts, explosion-proof electrical parts connection, mechanical or hydraulic transmission and safety devices. When designing and manufacturing it, on the one hand, consider the high temperature and spark generated by a single explosion-proof electrical equipment; on the other hand, consider the mechanical spark and high temperature caused by the frictional impact of mechanical moving parts. To a certain extent, the generation of sparks and arcs is controlled, and electrical sparks and mechanical sparks are controlled and eliminated by using corresponding explosion-proof technology, so that it cannot ignite the explosive gas mixture in the environment where it is located. The explosion-proof hoist used in some flammable and explosive related places can prevent the generation of arcs, sparks or overheating. Even if it is produced, it cannot ignite some related explosive mixtures around.

Explosion-proof Wire Rope Electric Hoist Application

BCD type explosion-proof wire rope electric hoist can be installed on the fixed bracket and used for lifting up and down. It can also be installed on straight-line rails and U-shaped rails with I-beams as the rails for linear curve movement, lifting up and down, left and right. It can also be used as a support for cantilever cranes, single-beam cranes, bridge cranes and gantry cranes.

Explosion-proof Electric Wire Rope Hoist Pre-factory Inspection

1. Each explosion-proof electric hoist should be qualified after the factory inspection and idling test requirements (including user special requirements inspection test items) can be shipped, and the product should be accompanied by a product certificate.

2. Check whether the explosion-proof electrical equipment selected for the explosion-proof hoist has an "explosion-proof certificate". Check the model, level and temperature group of the explosion-proof electrical equipment according to the design drawing of the explosion-proof electric hoist, and check the correctness of its installation.

3. The box contains explosion-proof electric hoist hoist, electric trolley, control box, hook, handle cable and control handle, which can be used after installation.

Explosion-proof Electric Wire Rope Hoist Common Questions

1. Question: Why can explosion-proof wire rope electric hoist be explosion-proof?

Answer: The exposed explosion-proof parts are made of special non-sparking materials. The motors, electrical appliances, electric trolley wheels, rope guides, hooks, and operating handles of explosion-proof electric hoists are all explosion-proof.

2. Can the explosion-proof wire rope electric hoist be used in circular railway?

Answer: The explosion-proof wire rope electric hoist can be equipped with the electric trolley installed on the I-beam track for straight or curved operation. It can be used with explosion-proof single-beam suspension cranes or explosion-proof single- or double-beam bridge cranes according to different requirements. It can also be fixed on the bracket and used directly.

3. Q: Do I need to add protective devices when using the explosion-proof wire rope electric hoist?

Answer: This explosion-proof electric hoist is suitable for indoor use at -25 ℃ ~ 40 ℃; special circumstances require the use of protective devices when used outdoors.

4. What are the electrical equipment for explosion-proof wire rope electric hoist?

Answer: The electrical appliance control includes the control box, the fire cut-off limiter, the control box connection frame, the flexible cable type power lead-in device and the electric wire, the electric cable and so on.

5. What are the components of the three-level and four-level explosion-proof control box?

Answer: With control button box and control cable, you can operate the explosion-proof electric hoist back and forth, left and right, and up and down. The control button box has four groups and six groups. Buyers choose according to the actual working conditions.

6. Is the three-level and four-level explosion-proof control box safe?

Answer: The button switch is equipped with a ground wire, which can be connected to the junction box of the control box shell to ensure the safety of use.

7. Are there any restrictions on the applicable environment of the three-level and four-level explosion-proof control boxes?

Answer: The explosion-proof grades of the equipment are: DIIBT4 and DIICT4, which are suitable for the zone 1 and zone 2 of the explosive gas mixture consisting of combustible gas or steam and air with temperature class ⅡA, ⅡB, ⅡC and temperature group T1-T4. It can be used in flammable and explosive work places (such as coal mines, pharmaceutical factories, chemical plants, etc.) that contain combustible gases, steam and air, which are easy to generate sparks.
