How Does a Truck Crane Work?
Introduction Most truck cranes use a hydraulic system to create the power they need to be effective. The hydraulic pump causes pressure and forces the pistons to move up and down. Truck cranes use two-gear pumps, which consist of inter-meshing gears that pressurize hydraulic oil. When the pressure is increased, the truck crane operator will push a foot down on the throttle and causing the pump to run faster. Truck cranes use a diesel engine that will generate up to 365 horsepower. The engine is attached to the three different two-gear pumps. The first one is the main pump, which controls the piston rod and is responsible for making the boom rise and fall. The main pump is able to generate the most pressure out of all the pumps, because it moves the most weight. The pilot pressure counterweight pump prevents the truck crane from tipping over. The steering and outrigger pump is used to stabilize the truck during any lifting operations. Parts A truck crane consists of many parts that all
