When selecting a crane for a job there are three important factors that have to be taken into account:
The length of the Boom (m)
The Radius from centre of rotation to the centre of lift (m)
The Capacity of the lift (t)
Looking at the graph please note the following, lifting capacity decreases with boom length and radius.
Therefore you need to know the following when considering a crane search:
Weight of the lift
Radius from the crane centre
Height of the lift (m)
Each of our cranes on the website has a diagram. Diagram contains all the specifications for the crane.
