Wolff Construction Cranes Houston

Hydraulic truck cranes are different compared to other crane models due to the way they particularly work. 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 kind of fluid that retains its volume, it is incompressible. Therefore, 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 operator utilizing the controls inside his cab. Normally, hydraulic truck cranes make use of a pump which has 2 gears.



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



Other Components

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



Jib: Jibs are latticed structure booms..



Boom Swing: Boom swings have a big roller or ball attached to the carrier. It is able to swing 360 degrees in both directions. Hydraulic devices control the swing and provide swings at various speeds in order to revolve the turntable gearbox.



Outrigger: Outriggers are units that cranes will use to maintain its balance. It utilizes hydraulics to lift the truck.



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



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



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



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



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