How mobile hydraulic cranes work?

 

These cranes can lift thousands of pounds using the simple concept of transmitting forces from point to point through a fluid. They work by harnessing the strength that liquid under pressure gives. Usually, the liquid is water or light oil as this works well with the system of pistons and pumps.

The cranes use a fixed system of pipes, constant pressure can be maintained once a part of the system has moved into place and this makes it extremely stable to use and able to support sizeable weights.

hydraulic truck cranes

These cranes are used to lift heavy loads up to tall heights so it’s important the truck is completely stable while lifting. The tires won’t offer the stability needed, so the truck employs outriggers which act as balances to keep the crane from leaning too much to one side or the other. Outriggers used in these types of cranes lift the tires on the truck off the ground.

The outriggers are the only mechanism used to balance the crane while lifting operations are performed. Also, detachable counterweights can be placed on the back of the crane on the underside of the cab. This prevents the crane from tipping forward during the operation. The counterweight needed for a specific lift is determined by the weight of the load, the boom radius, and its angle while in operation.
