It's important to consult with experts or professionals familiar with the specific safety requirements and regulations in your region or industry to ensure the appropriate selection, installation, and usage of explosion-proof wire rope hoists.

Application of Explosion Proof Electric Hoists 

• National Standards Compliance: The explosion-proof electric hoist complies with national standards such as JB/T 10222, GB3831, and GB383 These standards outline the general requirements for equipment in explosive environments and the specifications for equipment protected by flameproof enclosure "d."
• Work Level and Working Environment: The hoist has a work level of M5, indicating its suitability for heavy-duty operations. The specified working environment temperature for the crane is between -20 ℃ to +40 ℃, ensuring its functionality within this temperature range.
• Suitability for Explosive Gas Environments: This hoist is designed to operate in environments where explosive gases might be present. It's suitable for areas where the explosion-proof level is not higher than level B or C, or where the environment is formed by combustible gas, steam, and air, with an ignition temperature group not lower than T4 (135 ℃). This ensures that the hoist is safe to use in environments where there's a risk of explosion due to the presence of certain gases.
• Applicable Hazardous Areas: The hoist is suitable for use in Zone 1 or Zone 2 hazardous areas. Zone 1 refers to an area where an explosive atmosphere is likely to occur occasionally during normal operation, while Zone 2 is where an explosive atmosphere is not likely to occur frequently and, if it does, it will exist for a short period.
• Exclusion from Zone 0: Zone 0 refers to an area where an explosive atmosphere is present continuously or for long periods. This particular hoist is not designed for use in Zone 0 environments.

Overall, this detailed description highlights the precise conditions and environments in which the explosion-proof electric hoist can be safely and effectively used, ensuring compliance with specific national standards and safety regulations related to explosive atmospheres.

Note:

• Zone 0: A site that explosive gas mixture appears continuously, frequently for a short time or exists for a long time under normal conditions.
• Zone 1: A site that explosive gas mixture possibly occur under normal conditions.
• Zone 2: A site that explosive gas mixture can not appear under normal conditions but equipment failure or mis-operation may occur occasionally and shortly. 

See the following table for examples of hazardous gases applicable to the crane. For the other hazardous gases not listed in the table, see the appendix of GB383

Ignition group

explosion-proof electric hoist is equipped with original spatial rod support structure and hoisting device is arranged in the classic "C" type structure. The hoisting drive device drives the large-diameter drum group and the coaxial three-in-one drive device simultaneously drives the wheel groups on both sides. The rope wedge device and the pulley group are suspended on the support rod, in which the high-strength nylon pulley group and the hook group are used.

Advantages of Explosion-Proof Wire Rope Hoists:

Independent Core Technology: Collaborating with key universities and research institutions, these hoists develop core parts independently, ensuring controlled product quality and timely delivery. The motor, an explosion-proof three-phase induction motor with variable frequency electromagnetic braking, guarantees stable speed, substantial overload capacity, and high mechanical strength, ideal for intermittent operations with frequent hoisting and braking. Motor features include a standard insulation grade of F and IP65 protection.

Modular Design: Featuring a modular design, these hoists offer versatility. Four hoisting drives and two running drives can match various electric hoists ranging from 1-20t, adaptable to different structures like standard headroom, low headroom, crab running, and fixed type modes.

Compact Structure and Size Limit: Utilizing large-diameter drums across all series increases hoisting height and minimizes lateral limits, resulting in a smaller working blind area for cranes and providing users with more functional space.

Maintenance-Free, Energy-Efficient, and Eco-Friendly: Various design aspects contribute to these benefits:

• a. Reducers with high-precision hardened face gears come pre-filled with top-quality lubricating oil, requiring no replacement within the product's lifecycle.
