Truck Crane (Truck Mounted Crane)

A truck crane, with the other name of truck mounted crane, provides the mobility for the special needs. This machine mainly consist two parts: the lower and the upper. The lower always refers to the carrier, and the upper is mainly referred as the lifting component including the boom. These are mated together through a turntable, allowing the upper to swing from side to side.

Regarding the power of this machine, there are usually equipped with single-engine machines, with the same engine powering the undercarriage and the crane. The upper referred before is the powered via hydraulics run through the turntable from the pump mounted on the lower.
There were two engines for older model designs of hydraulic truck cranes. 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.

Truck crane contains truck cranes and the entire ground crane, is installed in a regular car chassis or special all-terrain chassis of a crane, the advantage is good mobility, transfer quickly. Chassis performance equal to the total weight of the same vehicle load truck, comply with the technical requirements of the highway vehicles, and can be in all kinds of highway came unstuck. General on and off the bus with two control room, when working out a leg remains stable. Apply to all kinds of loading bays, wharf, and the construction site of the place such as hanging heavy homework, is production is the largest, the most widely used type of crane. Xugong truck crane comprehensive performance indicators industry leading, now has a 8 tons ~ 1200 t * all series products. Truck crane has been eight years sales world first, 2010 QAY500 xugong all the earth by China machinery industry crane won first prize
