WebJun 1, 2024 · This is known as boom deflection and is an inbuilt safety feature of both lattice and hydraulic booms. It is designed to absorb the weight being lifted as the crane takes up the load, and reduces the risk … WebFeb 15, 2024 · These factors cause degradation of the control stability. In the proposed system, the boom deflection as well as the time delay in the system is explicitly considered and is incorporated into the controlled plant model. The experimental results showed that the attenuation for the boom deflection and the load swaying becomes better by using the ...

Webchart for the main boom. A failure in this area can be sudden and with little or no warning. 2. The second effect is that by utilizing lighter booms with more elastic steels boom deflection has increased dramatically. This is extremely important because as the boom deflects under an actual load it increases the load radius.
