Knuckle Boom Crane

The truck load crane is a kind of vehicle which is composed of crane and truck chassis. It is composed of lifting arm, turntable, frame, leg and so on. It realizes the mechanical action of the truck crane through the action of the mechanism such as luffing, stretching, turning and winch, and realizes the lifting operation through the combination of different actions. Truck crane is a kind of lifting, transport as one of the new efficient lifting transport equipment, some can also make the box into a form of flat dump, with its fast, flexible, efficient, convenient and loading and unloading, transport multi-functional advantages by more and more users know and accept. It can be divided to be front truck mounted crane and rear truck mounted crane.
