Wolff Construction Cranes Mesa

Hydraulic truck cranes are different compared to other crane models because of the way they particularly operate. Hydraulic cranes use oil rather than utilizing a winch in order to wind up cables to provide the lifting force. Because oil is a kind of fluid that retains its volume, it is incompressible. Therefore, 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 pressure generated by the hydraulic pump moves the piston. This action is maneuvered by the operator using the controls inside his cab. Typically, hydraulic truck cranes utilize a 2 gear pump.



The truck mounted crane is able to move from one site to another with little need for dismantling. The truck crane has one engine which could control both the truck and the crane.



Other Components

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



Jib: Jibs are latticed structure booms..



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



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



Load Movement Indicator: The load movement indicator is lights which flash so as to alert the driver that maximum weight is approaching.



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



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



Boom Elevation: The boom of the crane ascends with the use of double hydraulic cylinders that could be 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.
