The main technical parameters of bridge cranes include weight lifting, span, lifting height, running speed, lifting speed, work type, and electrification continuation rate of the motor. And if you want to get the overhead crane price, you need to give us the following parameters at least:
1. Lifting capacity of overhead crane
The lifting weight, also known as the rated lifting weight, refers to the maximum lifting load actually allowed by the crane in tons (t).
Bridge cranes are available in 5,10 (single hook), 15/3, 20/5, 30/5, 50/lO, 75/20, 100/20, 125/20, 150/30, 200/30, 250/30t (double hook) and many other. The number of molecules in the figure is the weight of the hook and the denominator is the weight of the hook. For example, a 15t/3t crane means that the rated lifting weight of the main hook is 15t, and the rated lifting weight of the auxiliary hook is 3t.
Bridge cranes can be divided into three levels according to the weight, 5 ~ lOt for small cranes, lO ~ 50t for medium-sized cranes, more than 50t for heavy cranes.
2. Span of overhead crane
The span of a bridge crane is the distance between the centerlines of the wheels at the two ends of the main beam of the crane, that is, the distance between the centerlines of the railcars, measured in meters (m).
Bridge crane spans 10.5, 13.5, 16.5, 19.5, 22.5, 25.5, 28.5, 31.5m, etc. Every 3m is a grade.
3. Lift height of overhead crane
The distance between the upper limit position and the lower limit position of the crane's spreader or gripping device (eg, grab, electromagnetic chuck) is called the lifting height of the crane in meters (m).
The commonly used lifting heights of cranes are 12, 16, 12/14, 12/18, 16/18, 19/21, 20/22, 21/23, 22/26, 24/26m and so on. Among them, the main hook lifts the height of the molecule, and the denominator lifts the height of the sub hook.
