55 Meter Boom Pump

Category: Pump Trucks

Attaining 180 ft heights, this impressive unit features a 5-section RZ boom configuration made of high quality, fine-grained steel in a box-type design for enhanced stability. Key features include a free flow hydraulic system for smooth controllable pumping as well as hard-chromed concrete cylinders and automatic lubrication of the concrete pistons for long service life. This pump has a fully adjustable volume control which allows very slow pumping while retaining full concrete pressure and boom speed.
