The 3-ton bridge crane is a high-efficiency overhead lifting system engineered for consistent and safe material handling across industrial environments. With its compact structure, flexible configuration, and robust performance, it is an essential solution for improving workflow, reducing labor intensity, and optimizing space usage in production lines, assembly shops, 倉庫, and maintenance facilities.
A 3-ton bridge crane is a versatile lifting solution designed for light to medium-duty material handling across a wide range of industries. Ideal for warehouses, manufacturing facilities, maintenance workshops, and assembly lines, this 高架起重機 system provides efficient and safe lifting for loads up to 3 噸 (3000 kg).
1. Bridge Girder
Available in single girder (light-duty, compact, economical) and double girder (higher lifting height, longer spans).
Constructed from Q235B/Q345B steel plates using robotic welding for maximum strength and reduced internal stress.
2. End Trucks
Machined for precision alignment and equipped with anti-friction bearings.
Driven by high-torque motors with geared motors for smooth movement.
3. Lifting Mechanism
High-efficiency electric wire rope hoist or chain hoist mounted on trolley.
Steel rope drum with precision machining ensures reliable lifting and long rope life.
4. Runway System
Heavy-duty runway beams and rail tracks ensure stable crane movement.
Power supplied via enclosed conductor bar or festoon system.

1. Overload limiter: Automatically stops hoisting if rated capacity is exceeded.
2. Upper/lower limit switches: Prevent over-travel of the crane hook.
3. Emergency stop system: Instant shutdown in case of abnormal operation.
4. Thermal overload protection: Built-in motor protection devices.
5. Buffer system: Shock-absorbing buffers on end trucks reduce collision risks.
6. Ground fault protection: Ensures operator and equipment safety.
1. Explosion-proof design (for oil, chemical, or mining industries)
