A crane beam is a core structural component of overhead cranes and gantry cranes. It provides the main load-bearing framework and supports the crane traveling system during lifting and movement operations. The design and manufacturing quality of crane beams directly affect crane stability, safety, and service life.

NYBON manufactures crane beams including main girders and crane end beams for various industrial crane applications, offering both standard and customized solutions.

Types of Crane Beams

Crane Main Girder

The crane’s main girder is the primary load-bearing structure of a crane. It supports the hoist and trolley system and transfers lifting loads to the crane end beams and rails.

Main girders can be designed as single girder or double girder structures depending on lifting capacity, span, and working duty. NYBON crane main girders are manufactured with optimized steel structures to ensure strength, rigidity, and long-term stability.

They are widely used in overhead cranes, gantry cranes, and industrial lifting systems.

Crane End Beam / End Carriage / End Truck

Crane end beams, also known as crane end carriages or end trucks, are installed at both ends of the main girder. They support the crane wheels and drive system, allowing the crane to travel smoothly along the runway rails.

NYBON supplies crane end beams in various configurations, including rigid and articulated designs, to suit different crane structures and installation conditions. Precision machining ensures accurate wheel alignment and reliable long-term operation.

Crane end carriages are the critical wheel assemblies mounted at both ends of the main girder, enabling the crane to travel along the runway beams. Because they are fundamental to the movement of overhead and gantry cranes, their application fields are vast across industrial sectors.

FAQ – Crane Girders

What is the difference between a crane main girder and an end beam?

The main girder carries the lifting load and supports the hoist trolley, while the end beam supports the crane wheels and allows the crane to travel along the rails.

Can crane beams be customized?

Yes. Crane beams can be customized in terms of span, lifting capacity, structure type, and applicable standards.

Are crane beams supplied separately or as part of a crane system?

NYBON can supply crane beams as standalone components or as part of a complete crane system.

What type of crane components do you produce?

We produce crane kits, including crane wheels, open winches, electric hoists, grab buckets, crane end trucks, and trolleys. etc
