JOSKIN offers several options of dorsal booms: first with a rear or front pivot point, then with 2 or 3 hydraulic joints. Depending on the intended use and whether or not you are using a spreading implement, you will easily find the mode that suits you best. The main advantage of a rear dorsal boom is its compactness and the possibility to pump from the rear of the tanker, while the front model offers a better visibility to the driver when handling it as well as a compatibility with all spreading implements (even the widest booms). The kinematics of dorsal booms allow a maximum lifting angle to be reached when pumping into an off-ground container or pit, and a maximum diving angle when pumping into an underground pit. The dorsal boom can be used with different pieces of equipment and in a variety of situations: vacuum pump, centrifugal pump, suction on funnel, etc. Different models are available, including with telescopic extensions, an optional turbo-filler or submerged turbo, etc. In short: a solution for every situation. All our dorsal booms are equipped as standard with a central lubrication system for a regular, easy and safe maintenance.
