To enable a large operating range (up to approx. 60m) while being able to transport the boom on a standard truck, the boom of these mobile concrete pumps is constructed in a lightweight design. Due to the complex kinematics with up to 6 individual joints and the large working areas, an optimal manual operation by a human operator is cognitively not possible.
1/12/2007 · The design of the Kinematics controller provides interfaces with external sensors and simulation packages. It also has allowed the implementation of the MATLAB Robotics Toolbox functions.

mounted concrete pump boom is typical flexible structure. Due to the increasing of boom length, the flexible characteristics play important role in the dynamics behavior. Three simulation models are built. The first is rigid model. The second is
Modern large-scale manipulators with hydraulic actuation like mobile concrete pump manipulators are increasingly used in industrial, construction, and other fields. Due to the large span of these manipulators, the static deformation accumulation to the endpoint has seriously affected the precise control of the endpoint. In this paper, we propose a static deformation-compensation method based

Concrete pump truck plays an important role in infrastructure construction and national economic development. In recent years, its boom system becomes longer, and its dynamic and control become mor Intended for healthcare professionals
Cazzulani et al. selected a 4-section boom mobile concrete pump truck and analyzed the load characteristics of them. Then, the boom damage was calculated by stress signal [ 3 ]. Sun et al. used a closed-loop detection and open-loop control strategy on the vibration suppression of a truck-mounted concrete displacing boom using angle signals [ 4 ].
1/1/2017 · Jiang et al. studied concrete pump outrigger's effect on the safety and stability of the system. The relationship between pipe length and outrigger area is obtained then . Ling et al. did the simulation of a mobile pump boom motion process.
Booms of modern mobile concrete pumps are vulnerable to elastic vibrations due to the light-weight construction. Although these vibrations can be effectively damped with appropriate controllers, the residual movement of the tool center point (TCP) during the pumping process is still uncomfortable for the workers guiding the end hose.
