A crane mounted on a truck carrier provides the mobility for this type of crane. This crane has
two parts: the carrier, often referred to as the Lower, and the lifting component which includes the
boom, referred to as the Upper. These are mated together through a turntable, allowing the upper
to swing from side to side. These modern hydraulic truck cranes are usually single-engine machines, with the same engine powering the undercarriage and the crane. The upper is
usually powered via hydraulics run through the turntable from the pump mounted on the lower. In
older model designs of hydraulic truck cranes, there were two engines. One in the lower pulled the
crane down the road and ran a hydraulic pump for the outriggers and jacks. The one in the upper ran
the upper through a hydraulic pump of its own. Many older operators favor the two-engine system
due to leaking seals in the turntable of aging newer design cranes.
