Bridge crane technical parameters

The technical parameters of bridge cranes characterize the operating capabilities of the cranes. They are the basic basis for the design of bridge cranes and are also the basic knowledge that all personnel engaged in lifting operations must master.

The basic technical parameters of bridge cranes mainly include:

1. Mass and load parameters: lifting capacity G, effective lifting capacity Gp, rated lifting capacity Gn, total lifting capacity Gt, maximum lifting capacity Gmax, lifting moment M, lifting overturning moment MA, total crane mass Go, wheel load P .

2. Crane size parameters: amplitude L, maximum amplitude Lmax, minimum amplitude Lmin, effective cantilever telescopic distance l, lifting height H, descending depth h, lifting range D, boom length Lb, crane inclination.

3. Movement speed parameters: lifting (lowering) speed Vn, descent speed Vm, slewing speed ω, crane (carriage) running speed Vk, trolley running speed Vt, luffing speed Vr.

4. Parameters related to the crane operating line: span S.

5. General performance parameters: working level, institutional working level.

Span refers to the horizontal distance between the center lines of the running track of the bridge crane, in m. The distance between the center lines of the running track of the trolley of the bridge crane is called the gauge of the trolley, and the operation of the jib crane running on the ground The distance between the center lines of the track is called the gauge of the crane.
