TK Booms provide safe, quick, and easy access for under-bridge construction and inspection. The 46TKRJ is the only boom that allows the operator to navigate down and directly under while working on a bridge. The versatile 46TKRJ is the only articulated telescopic boom that gives access below the machine, with a negative down reach of -6 metres. These units are ideally suited for under-bridge inspection, maintenance and ship repair work. Altra Construction Rentals delivers the Skyjack 46TKRJ and 66TK lifts across North America. Rent or purchase. Altra is Canada’s leader in bridge and dam specialty equipment.
