Hydraulic truck cranes are different from other crane types because of the way they specifically work. Hydraulic cranes utilize oil instead as opposed to using a winch in order to wind up cables to provide the lifting force. Because oil is a fluid which retains its volume, it is incompressible. Thus, this means it is among 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 action is maneuvered by the driver utilizing the controls inside his cab. Usually, hydraulic truck cranes make use of a 2 gear pump.
The truck mounted crane can move from one site to another with little need for dismantling. The truck crane has one engine which can control both the truck and the crane.
Boom Telescope: The boom telescope is due to a particular hydraulic operation which enables the boom to extend or retract.
Jib: Jibs are latticed structure booms..
Boom Swing: Boom swings have a large roller or ball connected to the carrier. It can swing 360 degrees in both directions. Hydraulic mechanisms provide swings at various speeds and control the swing in order to rotate the turntable gearbox.
Outrigger: Outriggers are units that cranes would utilize to maintain its balance. It uses hydraulics to lift the truck.
Load Movement Indicator: The load movement indicator is lights which flash so as to alert the driver that maximum weight is approaching.
Pump: The pump is the mechanism responsible for steering the outrigger.
Steel Cables: Steel reinforced cables run through the boom and the jib. They are able to 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 supplies.
Rotex Gear: The rotex gear is located under the cab and operated by hydraulics. It enables the boom to swivel on this gear.
