LHB type explosion-proof electric hoist overhead crane

The LHB type explosion-proof electric hoist overhead crane is specialized equipment suitable for flammable and explosive environments. Based on a standard overhead crane, key electrical components feature an explosion-proof design, and mechanical parts use non-sparking materials to reduce the risk of ignition caused by sparks. It can lift heavy loads of 5-40 tons, operates flexibly, and is widely used in locations with explosion-proof requirements such as the petroleum, chemical, and dusty industries, ensuring the safety of lifting operations in hazardous environments.

Its working principle is based on the synergy of mechanical transmission, explosion-proof drive, and precise control. While fulfilling conventional lifting functions, the explosion-proof design eliminates ignition sources such as sparks and high temperatures, ensuring operational safety in hazardous environments.

Structural Composition

The LHB type explosion-proof electric hoist overhead crane consists of four main parts: the bridge structure, the explosion-proof electric hoist, the travel mechanism, and the electrical control system. The functions and principles of each part are closely related:

• Bridge: Spans across the workshop or site, composed of main girders and end carriages. It bears the overall load and provides a lateral running track for the hoist.
• Explosion-proof Electric Hoist: The core execution component, integrating the hoisting mechanism (responsible for lifting and lowering the load) and the trolley travel mechanism (which moves the hoist laterally along the main girder).
• Crane Travel Mechanism: Mounted on the end carriages, it drives the bridge longitudinally along the floor rails, enabling three-dimensional movement of the load.
• Explosion-proof Electrical System: All electrical components (motors, switches, controllers, etc.) feature an explosion-proof design to prevent electrical sparks from causing ignition.
