A Hybrid Gyroscopic Stabilizer for Construction Tower Cranes and Gondolas under Environment Wind

Tower cranes and gondolas are widely used in construction projects for their load carrying capacity. However, these plants pose significant safety hazards to operation personnel from sway caused by load hoisting and environmental wind. To mitigate such safety hazards, we propose a control mechanism that combines both electronic and mechanical gyroscopes to produce a balancing torque and stabilize the crane load. In order to achieve this goal, a prototype stabilizer has been developed and its performance was examined in wind tunnel tests. The final design of the hybrid gyroscopic stabilizer utilizes the electronic gyroscope to track the real-time position and orientation of payload and adjusts the torque with air ejectors to counter balance the sway so that the amplitudes of oscillation can be quickly reduced.
