The Truck Mounted Knuckle Krane was first manufactured in 1970. This hydraulic knuckle krane is available in 2000, 4000, and 6000 pound capacities with powered options and has a lift height of 18 ft.

This heavy-duty hydraulic truck mounted knuckle krane can revolve 360° on its vertical axis and the most common use is loading and unloading delivery trucks. Many times this equipment is used to provide maintenance tasks on other construction equipment. This unique knuckle boom retracts and folds with a telescopic boom , making it a small package that saves space. When deployed with the knuckle boom in near vertical position, it provides a high head room, and in horizontal position, telescoped out, provides a long reach. With the knuckle lowered, the boom can reach down to below the ground level. This unit is ideal for big, bulky, or awkward loads. It can reach over, beyond, and beneath its own base mount.
More recently in 2004, the Knuckle boom design was adapted to the Self-Propelled Reversible Boom Crane. Now the advantages of the knuckle boom design can be enjoyed on a mobile shop crane. The Reversible Boom Knuckle Krane (RBKK) offers utmost versatility for in-plant assembly, maintenance, and work positioning applications.
The Truck-Mounted Knuckle Crane is built of heavy duty welded steel construction for industrial or construction use. Many times cranes are used in assembly lines for heavy installations, machine loading, feeding, heat treating, forging, and most of the time for truck loading and unloading. This unit is an efficient piece of equipment at an affordable price.
It’s all in the knuckle!
