INTRODUCTION

The LHB Type Explosion-Proof Hoist Double Girder Crane is a specialized double-girder overhead crane that utilizes a certified explosion-proof electric wire rope/chain hoist (such as Model HB or BCD) as its lifting mechanism. Designed to operate on top of elevated runway beams, it combines the high structural rigidity and load capacity of a double-girder bridge with a compact, cost-effective flameproof hoist trolley for hazardous industrial environments.

APPLICATION SCENARIO

[1] Light Manufacturing Workshops – Handling raw materials, semi-finished products, tools, and assembled components in plastics, electronics, textiles, and general manufacturing industries.

[2] Warehouses and Distribution Centers – Loading/unloading goods from trucks, moving pallets and cartons to storage racks, and efficient order picking operations.

[3] Machining Shops – Lifting workpieces, engine blocks, gearboxes, castings, and machine parts between lathes, mills, grinders, and other equipment.

[4] Assembly Lines – Moving components, motors, pumps, subassemblies, and finished products along the production line for efficient assembly processes.

[5] Maintenance Workshops – Servicing equipment parts, motors, pumps, gearboxes, and heavy tools in plant maintenance areas.

[6] Metalworking Shops – Handling steel bars, plates, pipes, welded structures, and fabricated components in fabrication and metalworking facilities.

ADVANTAGES

[1] Cost-Effective Design – Single girder structure reduces overall cost by 30%-40% compared to double girder cranes.

[2] Compact Headroom – Bottom-running hoist design maximizes lifting height under limited building clearance.

[3] Fast Installation – Lightweight structure with simple rail requirements allows quick installation, typically 5-7 days.

[4] Easy Maintenance – Modular hoist design with standard components allows quick replacement and simple daily inspection.

[5] Flexible Control Options – Available with pendant control, remote radio control, or cabin control for operator convenience.

[6] Smooth Operation – Optional VVVF frequency control provides smooth start/stop and accurate load positioning.
