Wolff Construction Cranes Arlington

Hydraulic truck cranes are different compared to other crane models because of the way they particularly operate. Hydraulic cranes utilize oil rather than using a winch in order to wind up cables to provide the lifting force. As oil is a kind of fluid which retains its volume, it is incompressible. Therefore, this means it is one of the most ideal types 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 driver from the controls inside his cab. Usually, hydraulic truck cranes use a pump which has 2 gears.



The truck mounted crane is able to move from one site to another with little need for dismantling. The truck crane has a single engine which can control both the crane and the truck.



Other Components

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



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



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



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



Load Movement Indicator: The load movement indicator is lights that flash in order to alert the driver that maximum weight is approaching.



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



Steel Cables: Steel reinforced cables 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 utilizing double hydraulic cylinders which allow for raising and lowering materials.



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