Wolff Construction Cranes
Hydraulic truck cranes are different from other crane models because of the way they specifically work. Hydraulic cranes use oil rather than utilizing a winch in order to wind up cables to provide the lifting force. Since oil is a fluid that retains its volume, it is incompressible. Therefore, this means it is amongst 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 action is maneuvered by the operator from the controls in his cab. Typically, hydraulic truck cranes utilize a pump that has 2 gears.
The truck mounted crane is able to move from one location to another with little need for dismantling. The truck crane has one engine which controls both the truck and the crane.
Boom Telescope: The boom telescope is due to a specific hydraulic operation which enables the boom to retract or extend.
Jib: The jib is a latticed structure which extends from the boom.
Boom Swing: Boom swings have a big roller or ball attached to the carrier. It can 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 using hydraulics to lift the truck.
Load Movement Indicator: The load movement indicator is lights that 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 14,000 lbs. or 6350 kg.
Boom Elevation: The crane's boom ascends using double hydraulic cylinders which allow for lowering and raising materials.
Rotex Gear: The rotex gear is located underneath the cab and operated by hydraulics. It allows the boom to swivel on this gear.
