A Bridge Crane system consists of three major components

1.the Bridge Crane, which traverses across the runway

2.the hoist & trolley, which traverses across the bridge and lifts up and down

3.the runway, which is tied to the building structure.

QD/Single girder/Double girder overhead crane

Capacity: 5~400t

Span: 7.5~45m

Work duty: A5(m2), A6, A7(m3)

Operated by cabinet

Single girder overhead crane is standard heavy duty crane. We choose top

supplier for motor, reducer, brake, steel plates and electrical syste.

Inverter, radio control is upon request.

Top Running vs. Under Running

Top Running vs. Under Running is primarily determined by two factors:

Capacity - Although under running can be up to 25 ton capacity, the practical limit is more like 15 tons and the economic sweet spot is 1 to 7.5 ton range.
Support Structure - Under running can be suspended directly from the overhead steel (for lighter cranes). Top running cranes will require a bracket off the building support steel (up to 10 tons capacity) or independent columns for heavier capacities.

Safety feature:
1.Weight overload protection device,
2.Top quality long time bearing polyurethane materials buffer,
3.Crane traveling limit switch, Voltage lower protection function,
4.Emergency stop system,
5.Current overload protection system and so on!

Design and construction rules:
All the standards which is required for the crane is the Chinese standard.
