Telescopic Boom Cranes

Boom sections that are marked off in equal increments, as shown on the boom in figure 12-27, make it easier for the operator or signalman to make sure each section is extended equally. When a load is placed on a telescopic boom, the load weight on the boom causes the hydraulic rams within the boom to stiffen up and slightly curve.

 · However, when the load being moved is not centered on the point of effort and at perpendicular angles to that point of effort, the force required by the cylinder changes. If you have a crane, for example, the cylinder pushes on the boom often very far from the load. In fact, the load distance can be ten times the effort distance, sometimes more.
