With a 138 ft. 1 in. horizontal reach, the five-section MX 43/47Z-meter truck-mounted placing boom is one of the largest booms in the industry that does not require counterweight. It features a straighter pipe for a less stressful concrete flow, reducing wear on parts. The boom also can adapt to any lattice tower with a cross-section of 7 1/2 x 7 1/2 ft.
