End Beams: Mounted at both ends of the main girder, they support the entire structure and guide the crane along the factory tracks.

Electric Hoist: Responsible for lifting and lowering cargo, serving as the critical component for completing lifting operations.

Travel Mechanism: Drives the crane and hoist for smooth movement, enabling both longitudinal and lateral travel.

Control System: Operates all crane functions via pushbutton panels or remote controllers, ensuring simple, safe, and reliable operation.

Working Principle

The working principle of a EOT crane single girder involves moving cargo vertically, horizontally, and front-to-back through an electric drive system to accomplish material handling operations.

A single-girder EOT crane consists of a single main girder, an electric hoist, a traveling mechanism, and a control system. The electric hoist is mounted beneath the main girder, enabling lateral movement along the girder. The main girder traverses the longitudinal factory tracks via end beams and wheels.

Working Principle

The coordinated operation of the bridge structure and the clamp lifting device enables the safe clamping, lifting, and transportation of steel slabs. During operation, the trolley moves above the steel slab, and the clamps open and align with the slab under the drive of the lifting mechanism or hydraulic system. After the lifting mechanism is activated, the clamps automatically grip the steel slab, forming a reliable self-locking or hydraulic clamping force. Then, the crane, through the bridge and trolley running mechanisms, smoothly transports the steel slab longitudinally and laterally to the designated position. Throughout the entire process, frequency conversion control and the PLC system precisely regulate the lifting and traveling speeds, and continuously monitor the clamping status and load conditions, ensuring that the steel slab does not slip under high-temperature or heavy-load conditions, thus guaranteeing safe and efficient continuous handling operations.

Working Principle

The explosion-proof bridge crane moves horizontally along the factory tracks via its bridge structure, positioning the lifting mechanism and hook over the material to be lifted. The lifting mechanism uses an explosion-proof motor to drive a wire rope or chain, lifting heavy objects vertically, while an explosion-proof brake ensures safe and reliable lifting operations. The trolley moves back and forth on the bridge structure, allowing for lateral transport of materials across the span. The entire operation is controlled by an explosion-proof control system (pendent control, wireless remote control, or control cabin), ensuring that no sparks or arcs are generated in flammable or explosive environments, while also allowing for high-frequency, heavy-duty, and continuous operation.
The key to an explosion-proof crane lies in all electrical components, drive devices, and control systems complying with explosion-proof standards, ensuring stable and safe lifting operations even in hazardous environments.

Parts Underslung Overhead Crane

Underhung bridge cranes operate through the coordinated action of various core components, each designed for compactness and optimal compatibility. Understanding the composition of these main components will help you in equipment selection and subsequent operational management.

Main Girder: The main load-bearing structure of the crane, typically a box beam or I-beam structure, used to support the lifting mechanism and bear the weight of the load.
End Trucks / Running Units: Installed at both ends of the main girder, they run on the lower flange of the runway beam via wheel sets, enabling the entire crane to move laterally.
Hoist: Includes the electric hoist, motor, reducer, and brake, responsible for lifting and lowering the load.
Runway Beam: Composed of the factory building structure or independent steel beams, providing the foundation for the crane’s operation and load bearing.
Electrical Control System: Used to control lifting, traversing, and braking, with optional control methods such as pendant control and remote control.
Safety Devices: Including limit switches, overload protection, emergency stop devices, etc., to ensure the safe operation of the equipment.

 

Working Principle

An underslung bridge crane operates by suspending the entire machine from the lower flange of the factory’s crane runway beam, enabling the lifting and horizontal movement of materials within the workshop. Once the crane is powered on, the electric hoist handles the lifting and lowering of goods, while the traveling mechanisms at both ends of the main beam move smoothly along the underside of the runway beam, allowing the load to move horizontally within the workshop.

During operation, the lifting, traversing, and long travel movements work in coordination, and the operator can control the equipment precisely using a control handle or remote control. Because the entire crane is positioned below the runway beam, it effectively reduces the required headroom in the factory, making it suitable for material handling operations in workshops with limited space.

 

Specifications

Under Running Overhead Cranes can be flexibly configured based on the factory building structure, operating environment, and usage frequency. Key parameters such as lifting capacity, span, lifting height, and working class can all be customized according to actual working conditions. The following are common technical specifications for underhung bridge cranes.
