INTRODUCTION

The LDP Type Electric Single Girder Overhead Crane is an ultra-low headroom bridge crane designed specifically for workshops with limited vertical clearance. By offsetting the electric hoist trolley to one side of the main box girder rather than hanging it underneath, it maximizes effective hook travel height while operating on top of elevated runway beams.

APPLICATION SCENARIO

[1] Precision Manufacturing Workshops – Handling precision parts, machined components, dies, and finished products in aerospace, automotive, and medical device manufacturing where smooth operation prevents damage to delicate parts.

[2] Assembly Lines – Moving components, motors, pumps, subassemblies, and finished products along the production line. Low-noise operation improves working conditions on assembly lines.

[3] Warehousing and Logistics Centers – Loading/unloading goods from trucks, moving pallets and cartons to storage racks, and efficient order picking operations with precise positioning.

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

[5] Light Industrial Facilities – Handling raw materials, semi-finished products, tools, and assembled components in plastics, electronics, textiles, and general manufacturing.

[6] Maintenance Workshops – Servicing equipment parts, motors, pumps, gearboxes, and heavy tools in plant maintenance areas with reliable daily operation.

ADVANTAGES

[1] Smooth Operation – Precision trolley with sealed bearings and low-resistance wheels provides smooth travel and accurate positioning.

[2] Low Noise Design – Optimized gearboxes and rubber buffers reduce operational noise for a better working environment.

[3] Reinforced Box-section Girder – 15%-20% less deflection than I-beam designs, improving load stability and safety.

[4] Higher Duty Rating – Upgraded components allow A5 duty class for 8-12 hours of daily continuous operation.

[5] Cost-Effective – Single girder design reduces cost by 30%-40% compared to double girder cranes.

[6] Flexible Control Options – Available with pendant, remote radio, or cabin control, with VVVF speed control optional.
