Wolff Construction Cranes

Wolff Construction Cranes

Hydraulic truck cranes are different compared to other crane types due to the way they specifically operate. 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 which retains its volume, it is incompressible. Thus, this means it is amongst 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 operator from the controls within his cab. Typically, hydraulic truck cranes utilize a 2 gear pump.

The truck mounted crane could move from one location 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 is due to a specific hydraulic operation that enables the boom to extend or retract.

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

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

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

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

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

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

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

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