Control Stabilization of Multilink Manipulators in a Truck-mounted Concrete Boom Pump

Truck-mounted concrete boom pumps are now used on all large construction sites. The fresh concrete is pumped through a feed pipe fitted to a boom of up to 70 m in length before being released through a wire-reinforced end placing hose. Due to their lightweight engineering and discontinuous conveyance principle based on the use of a two-piston pump, concrete boom pumps exhibit a tendency to vibrate that can both endanger the operator of the end placing hose and expose components to high levels of loading. Enhanced boom stability therefore needs to be achieved while retaining the benefits of modern lightweight engineering. It was against this backdrop that a boom simulation model which factors in relative motion and steel deformation in individual boom segments as well as the behavior of the respective hydraulic cylinders was developed at the Endowed Chair of Construction Machinery at Technische Universität Dresden.
