Wolff Construction Cranes Dallas

Due to the way they specifically work, hydraulic truck cranes are different compared to other crane models. Rather than using a winch in order to wind up cables to provide the lifting force, hydraulic cranes utilize oil instead. Because oil is a type of fluid that retains its volume, it is incompressible. Thus, 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 hydraulic pump generates a pressure that moves the piston. This action is maneuvered by the operator using the controls in his cab. Usually, hydraulic truck cranes use a 2 gear pump.



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



Other Parts

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



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



Boom Swing: Boom swings have a big ball or roller attached to the carrier. It could swing 360 degrees in both directions. Hydraulic mechanisms control the swing and provide swings at various speeds in order to revolve the turntable gearbox.



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



Load Movement Indicator: The load movement indicator is lights that flash so as to warn the operator that maximum weight is approaching.



Pump: The pump's purpose is to steer the outrigger.



Steel Cables: Steel reinforced cables run through the jib and the boom. 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 which can be lowered and raised.



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