Wolff Construction Cranes Provo

Due to the way they particularly operate, hydraulic truck cranes are different from other crane types. Instead of using a winch in order to wind up cables to provide the lifting force, hydraulic cranes utilize oil instead. Since oil is a type of fluid that retains its volume, it is incompressible. Thus, this means it is one of the most ideal types of fluids for pushing pistons towards the direction the force is going to be exerted.



The pressure created by the hydraulic pump moves the piston. This action is maneuvered by the driver using the controls in his cab. Usually, hydraulic truck cranes use a 2 gear pump.



The truck mounted crane could move from one site to another with little need for dismantling. The truck crane has a single engine that controls both the crane and the truck.



Other Parts

Boom Telescope: The boom telescope enables the boom to extend or retract because of hydraulics.



Jib: Jibs are latticed structure booms..



Boom Swing: Boom swings have a large roller or ball connected to the carrier. It could swing 360 degrees in both directions. Hydraulic mechanisms control the swing and provide swings at various speeds in order to rotate 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 alert the driver that maximum weight is approaching, the load movement indicator's lights flash.



Pump: The pump's purpose is to steer the outrigger.



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



Boom Elevation: The crane's boom ascends with the use of double hydraulic cylinders that are capable of being raised and lowered.



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