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

Machinery & Assembly: Workshops, production lines, and light manufacturing plants.
Warehouses & Logistics: Loading, unloading, and material handling in storage areas.
Maintenance Shops: Lifting heavy components during equipment servicing.
General Industrial Use: Indoor lifting tasks without explosive or harsh environments.

ADVANTAGES

Cost-Effective: Single girder design lowers equipment cost and reduces building structural requirements (lower wheel loads).
Space-Saving: Compact structure maximizes headroom and floor space utilization.
Easy Installation & Maintenance: Simple structure, lightweight, and easy to install, inspect, and maintain.
Smooth & Stable Operation: Equipped with reliable electric hoists and smooth travel mechanisms; optional VFD for precise control.
Flexible Customization: Available in various spans, lifting heights, and control modes (pendant, remote, or cabin) to fit specific workshop layouts.
