PB21AM3R Stationary Placing Boom

PB21AM3R model concrete hydraulic stationary placing boom is TRUEMAX special
design for climbing formwork type construction project.It is suitable for high
rising building which can be climbed with climbing formwork to assistant to
placing the concrete to all available location and improve the efficiency of
project construction process.

Same as other concrete hydraulic placing boom, PB21AM3R model is connected with
concrete stationary pump as a concrete equipment for delivery and placing the
concrete by pipe. It is a professional concrete delivery equipment and it is very
efficient to delivery concrete to any available location for continuous placing
concrete by pipe. It is easier to reach bigger range and flexible to placing
concrete. Welcome to inquiry.

Features of Stationary Placing Boom
