PRODUCT INTRODUCTION

The LX model electric single girder suspension overhead crane is a light-duty lifting solution designed for factories, warehouses, and stock yards where the distance from the rail surface to the lower edge of the roof truss is limited. The crane is suspended directly from the existing roof I-beam structure — requiring no floor-standing support columns — keeping the entire floor area clear for forklifts, production lines, and personnel movement.The crane consists of a single main girder fabricated from welded steel plate and I-beam sections, connected to end carriages that run on the bottom flange of the overhead runway beams. An electric wire rope hoist travels along the lower flange of the main girder, with an optional cantilever of 0.5 to 1 metre at either end.The modular bolt-together design simplifies installation and routine maintenance, while the compact, lightweight structure minimises the load on the supporting roof framework. The crane is available in six standard models covering capacities from 0.5 to 10 tonnes, with spans from 3 to 16 metres and lifting heights from 6 to 18 metres. Work duty is rated from A3 to A5, suitable for light to moderate service cycles in ambient temperatures from -25°C to +40°C.

FEATURES

1
Column-Free Suspended Installation,The crane runs on the bottom flange of runway beams suspended directly from the existing roof structure, requiring no floor-standing support columns.
2
Compact and Lightweight Single-Girder Design,The single main girder, fabricated from welded steel plate and I-beam sections, delivers a favourable deadweight-to-rigidity ratio while imposing minimal wheel loads on the supporting roof framework.
3
Optimised for Low-Headroom Environments,The underslung design positions the hoist close to the roof structure, maximising usable hook height in facilities with limited ceiling clearance.
4
Flexible Dual-Speed Hoist and Control Options,The crane is equipped with a CD1 single-speed or MD1 dual-speed electric wire rope hoist, delivering both efficient vertical movement and precise load positioning.
5
Modular Bolt-Together Construction for Easy Installation and Maintenance,The crane‘s core components — main girder, end carriages, hoist, and electrical system — are standardised, independently replaceable modules.

FAQ

What is the main difference between an underhung (suspension) crane and a top-running crane?

add subtract
The primary difference lies in how the end carriages and runway rails are supported within the facility: Underhung / Suspension Crane: The end carriages travel along the bottom flange of runway beams suspended directly from the roof trusses or ceiling structure. It requires no ground support columns or brackets, leaving maximum open floor space. Top-Running Crane: The crane bridge travels on top of rails supported by independent building columns or bracket structures. It is preferred for heavy capacities (>10 tons) and extremely long spans.

What are the capacity, span, and building requirement limits for a single girder suspension crane?

add subtract
A single girder suspension overhead crane is optimized for light-to-medium material handling: Capacity & Span: Typically engineered for lifting capacities from 0.5 tons to 10 tons, with spans up to 18 to 22 meters. Roof Structural Evaluation: Because the crane load is hanging from the roof, your facility’s ceiling trusses or roof I-beams must be evaluated to ensure they can support the combined deadweight and dynamic wheel loads.

How does an underslung crane improve hook approaches and factory floor space utilization?

add subtract
Underslung overhead cranes excel at maximizing coverage in cramped or specialized workshop spaces: Zero Floor Obstruction: Eliminates the need for concrete foundations, support pillars, or aisle-blocking steel columns, maximizing production and assembly layout flexibility. Superior Side Hook Approach: By extending the main girder beam beyond the runway tracks (cantilever ends), the hoist can reach much closer to side walls and machinery boundaries than a traditional top-running crane.

Can a single girder suspension crane feature an interlock system to transfer loads across different bays?

add subtract
Yes, one of the unique advantages of Yuntian suspension bridge cranes is compatibility with Monorail Track Interlock Systems: Cross-Bay Material Transfer: The suspension crane bridge can align and lock precisely with an adjacent crane bridge or fixed monorail spur track. Seamless Hoist Travel: Once interlocked, the hoist trolley can travel directly from one building bay to another without putting down or re-hooking the load, significantly speeding up assembly line workflows.
