Wolff Construction Cranes San Diego

Hydraulic truck cranes are different compared to other crane types due to the way they particularly operate. Hydraulic cranes use oil instead as opposed to utilizing a winch in order to wind up cables to provide the lifting force. As oil is a type of fluid which retains its volume, it is incompressible. Hence, this means it is among the most ideal kinds of fluids for pushing pistons towards the direction the force is going to be exerted.



The hydraulic pump generates a pressure which moves the piston. This action is maneuvered by the operator from the controls inside his cab. Typically, hydraulic truck cranes make use of a 2 gear pump.



As the actual crane itself is mounted on a truck, it could travel numerous distances from job to job and there is little dismantling involved. The truck crane has a single engine which controls both the truck and the crane.



Other Components

Boom Telescope: The boom telescope is due to a particular hydraulic operation that allows the boom to extend or retract.



Jib: The jib is a latticed structure that extends from the boom.



Boom Swing: The boom swing is a big roller or ball that is connected to the carrier. It could swing 360 degrees in both directions. Hydraulic mechanisms control the swing and provide swings at varying speeds in order to revolve the turntable gearbox.



Outrigger: The outrigger is a unit that helps the crane maintain its balance by using hydraulics to lift the truck.



Load Movement Indicator: In order to warn the driver that maximum weight is approaching, the load movement indicator's lights flash.



Pump: The pump is the device responsible for steering the outrigger.



Steel Cables: Steel reinforced cables run through the boom and the jib. They could generate up to 6350 kg or 14,000 lbs.



Boom Elevation: The crane's boom ascends using double hydraulic cylinders that allow for raising and lowering materials.



Rotex Gear: The rotex gear is operated by hydraulics and located underneath the cab. It enables the boom to swivel on this gear.
