Wolff Construction Cranes Houston

Due to the way they specifically work, hydraulic truck cranes are different from other crane types. Instead of utilizing a winch in order to wind up cables to provide the lifting force, hydraulic cranes use oil instead. As oil is a kind of fluid that retains its volume, it is incompressible. Hence, this means it is among the most ideal kinds of fluids for pushing pistons towards the direction the force is going to be exerted.



The pressure created by the hydraulic pump moves the piston. This particular action is maneuvered by the operator using the controls in his cab. Typically, hydraulic truck cranes utilize a pump which has 2 gears.



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



Other Components

Boom Telescope: The boom telescope is due to a specific hydraulic operation which allows the boom to extend or retract.



Jib: Jibs are latticed structure booms..



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



Outrigger: The outrigger is a unit that helps the crane maintain its balance by using hydraulics to lift the truck.



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



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 can generate up to 6350 kg or 14,000 lbs.



Boom Elevation: The crane's boom ascends using double hydraulic cylinders which allow for lowering and raising materials.



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