Wolff Construction Cranes

Wolff Construction Cranes

Hydraulic truck cranes are different from other crane types because of the way they specifically operate. Hydraulic cranes utilize oil rather than using a winch in order to wind up cables to provide the lifting force. As oil is a fluid that retains its volume, it is incompressible. Therefore, this means it is among the most ideal types of fluids for pushing pistons towards the direction the force is going to be exerted.

The hydraulic pump generates a pressure that moves the piston. This action is maneuvered by the driver from the controls within his cab. Normally, hydraulic truck cranes utilize a pump that has 2 gears.

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

Other Parts
Boom Telescope: The boom telescope allows the boom to retract or extend because of hydraulics.

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

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

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

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

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

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

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

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