Product Details
Explosion-proof electric hoist overhead crane is a special lifting equipment specially designed for flammable and explosive environments. It is widely used in petrochemical, mining, military, pharmaceutical, dusty workshops and other places with explosive gas or dust. Its core feature is explosion-proof performance, ensuring safe operation in hazardous environments. The key performance features and technical introduction are as follows:
- Explosion-Proof Performance
Explosion-proof RatingThe equipment complies with Ex d IIB T4 Gb (or higher) explosion-proof standards. Key components such as motors, electrical control boxes and operation buttons adopt explosion-proof design, which can effectively prevent explosions caused by electric sparks or high temperatures.
Applicable EnvironmentSuitable for explosive gas environments in Zone 1 and Zone 2 (such as methane, hydrogen, ethylene, etc.) or combustible dust environments in Zone 21 and Zone 22 (such as coal dust, aluminum powder, flour, etc.).
- Structure & Materials
Explosion-Proof Design
Motor: Fully enclosed explosion-proof type to prevent internal sparks from escaping.
Electrical System: Explosion-proof control box, explosion-proof limit switch, explosion-proof cables, etc. All electrical components are certified by national explosion-proof standards.
Mechanical Structure: Gearbox, brake and other parts use spark-free materials or special sealed design.
Metal StructureMain girders and end girders are made of high-quality steel with surface anti-corrosion treatment (sandblasting, galvanizing or corrosion-resistant coating), suitable for humid or corrosive environments.
- Safety Performance
Multiple Protection Mechanisms
Overload Protection: Explosion-proof overload limiter monitors load in real time and cuts off power automatically in case of overload.
Limit Protection: Dual limit upward travel switches.
Emergency Stop Button: Explosion-proof emergency stop device for unexpected situations.
Phase Failure Protection: Automatically cuts off the circuit when power supply is abnormal.
- Hoisting Mechanism
Adopts explosion-proof wire rope electric hoist as the lifting mechanism, with reliable performance and high cost performance.
