Wolff Construction Cranes Long Beach

Due to the way they particularly work, hydraulic truck cranes are different from other crane types. As opposed to utilizing a winch in order to wind up cables to provide the lifting force, hydraulic cranes utilize oil instead. Since oil is a fluid which retains its volume, it is incompressible. Hence, 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 driver from the controls inside his cab. Normally, hydraulic truck cranes make use of a 2 gear pump.



As the actual crane itself is mounted on a truck, it could travel numerous distances from site to site and there is little dismantling involved. The truck crane has one engine which controls both the crane and the truck.



Other Components

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 ball or roller connected to the carrier. It is able to swing 360 degrees in both directions. Hydraulic mechanisms control the swing and provide swings at various speeds in order to rotate the turntable gearbox.



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



Load Movement Indicator: In order to warn the operator that maximum weight is approaching, the load movement indicator's lights flash.



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



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



Boom Elevation: The boom of the crane ascends using double hydraulic cylinders that allow for raising and lowering materials.



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