What can affect a mobile crane lifting capacity?

dynamic factors caused by the crane motion and the load e.g. for boom movement, application of brakes, swaying of the load, and. wind effects on the load and boom.

What affects the amount of weight a crane can lift?

For example, if the boom of the crane is extended to 250 feet and the radius (the distance from the center of the load to the center of the crane) is 180 feet, the max load weight drops considerably. The shorter the lift, the more weight can be handled. Transportation of the cranes also needs to be considered.

How much weight can a mobile crane lift?

Our heavy crane selection can lift anything from 200 to 700 tonnes, while still being fully mobile. Although this weight cannot be lifted to the height of a tower crane, sometimes height has to be substituted for unrivalled lifting power.
