Importance of outriggers in parts of Crane

On the whole the crane comprises of many Crane Parts and their description is outlined here in brief. The prime use of it is to carry or rather move heavy load from one destination to other. It is one of the very commonly used mechanical assistants.

As they are used to lift heavy loads to tall heights so it is important that the truck be completely stable during the lifting operation. The tires donot offer the stability needed, so the truck employs outriggers that act as balances to keep it from leaning too much to one side or the other. They use hydraulics to lift the entire truck, tires and all, off the ground. They are basically comprised of the beam, which is the leg and the pad, which is the foot. Sometimes, "floats" are placed under the pad to dissipate the force of the crane and the load over concrete or pavement. Floats are usually wood planks that are lined up to create a base that is larger than the pad itself.

The outriggers are only one mechanism used to balance the crane during lifting operations. There are also detachable counterweights that can be placed on the back of the crane on the underside of the cab. These counterweights prevent the crane from tipping forward during operation. The amount of counterweight needed for a particular lift is determined by the weight of the load, the radius of the boom and the boom's angle during operation. The 70-ton Link-Belt truck crane has counterweights that come in 4,000-pound sections. The counterweights are only used during lifts; they have to be removed before the truck can be driven. Thus it clear that the backbone of the Crane.
