Wolff Construction Cranes

Wolff Construction Cranes

Hydraulic truck cranes are different from other crane types due to the way they specifically operate. Hydraulic cranes utilize oil instead as opposed to using a winch in order to wind up cables to provide the lifting force. Because oil is a fluid which retains its volume, it is incompressible. Therefore, this means it is one of 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 particular action is maneuvered by the driver utilizing the controls inside his cab. Usually, hydraulic truck cranes make use of a 2 gear pump.

Because the actual crane itself is mounted on a truck, it is able to travel numerous distances from job to job and there is little dismantling involved. The truck crane has one engine that can control both the crane and the truck.

Other Parts
Boom Telescope: The boom telescope enables the boom to retract or extend thanks to hydraulics.

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

Boom Swing: Boom swings have a large ball or roller connected to the carrier. It could swing 360 degrees in both directions. Hydraulic devices provide swings at varying 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 utilizing hydraulics to lift the truck.

Load Movement Indicator: In order to alert the operator 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 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 supplies.

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