PRODUCTS & CASES

Single girder overhead cranes are rail-mounted industrial lifting machines that move along two parallel runway beams, with matched hoist units traveling horizontally across the main girder for cargo lifting tasks. Standard Chinese single girder overhead crane assemblies consist of main girders, end carriages, long-travel drive mechanisms, electric hoist lifting units and complete electrical control parts. Suited for large-span factory buildings, the full crane body travels longitudinally along fixed rails installed on both sides of workshop walls.

LD electric single girder overhead cranes are engineered in strict compliance with GB3811-2008 and JB/T1306-2008 national industrial standards. This general-purpose lifting equipment can be paired with CD1, MD1 and WH164 series electric hoists. As one of the most cost-effective and widely adopted handling machines, it serves indoor production workshops and storage hubs across countless industries. Favored for its streamlined layout, affordable cost and minimal space occupation, it stands out among conventional industrial lifting machinery.

This single girder model can adopt standard I-beam or box-section steel girders, with most available load capacities falling below 20 tons. It delivers stable cyclic lifting performance for steel processing plants, hydropower station construction sites, general storage yards and all kinds of manufacturing workshops.

1. Robust box-type main girder with outstanding integral rigidity and load-bearing stability

2. Post-weld shot blasting treatment eliminates internal welding stress across the whole crane frame

3. Surface coated with epoxy zinc-rich primer, with a total paint film thickness reaching 140μm for anti-corrosion performance

4. Main girders and end carriages are fastened with Grade 10.9 high-strength bolt connections for reliable assembly

5. Multiple drive choices including integrated electric gear reducers and classic LD long-travel driving systems

6. Shock-free reciprocating travel, responsive braking performance and extended overall service lifespan

Electrical Control System

1. Power supply is delivered via overhead sliding contact line carriers

2. Separate independent control circuits for crane long-travel and hoist cross-travel, enabling simultaneous coordinated movement

3. Corrosion-resistant wired pendant control with IP54 ingress protection rating

4. Lifting cables are mounted on sliding cable trolleys that move smoothly along C-shaped steel guide rails without jamming

Complete Safety Protection Devices

Built-in full safety accessories include load limiters, lifting & travel limit switches, interlock protection assemblies, travel buffers, rail sweeper plates, safety shielding covers, busbar protective plates, end anti-collision units, main power isolation switches, emergency stop braking systems and motor overload protection modules.
