Wolff Construction Cranes
Hydraulic truck cranes are different from other crane models because of 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 fluid that 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 pressure generated by the hydraulic pump moves the piston. This particular action is maneuvered by the operator utilizing the controls in his cab. Usually, hydraulic truck cranes make use of a pump that 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 that controls both the crane and the truck.
Boom Telescope: The boom telescope is due to a particular hydraulic operation that enables the boom to extend or retract.
Jib: The jib is a latticed structure that extends from the boom.
Boom Swing: The boom swing is a large roller or ball that is connected to the carrier. It is able to 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: The outrigger is a unit that helps the crane maintain its balance by utilizing hydraulics to lift the truck.
Load Movement Indicator: The load movement indicator is lights which flash in order to warn the operator 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 can generate up to 6350 kg or 14,000 lbs.
Boom Elevation: The crane's boom ascends using double hydraulic cylinders which allow for raising and lowering materials.
Rotex Gear: The rotex gear is located underneath the cab and operated by hydraulics. It enables the boom to swivel on this gear.
