Investigation of the dynamics of an overhead crane lifting process in a vertical plane [PDF]
Transport, 2005 The paper analyses the dynamic behaviour of supporting structure of an overhead crane during the operation of a hoisting mechanism. The crane is expected to operate with a hook and to carry 50 kN of weight. The electric hoist consists of an asynchronous

Nonlinear tracking control of a 3-D overhead crane with friction and payload compensations
Journal of Mechatronics, Electrical Power, and Vehicular Technology, 2016 In this paper, a nonlinear adaptive control of a 3D overhead crane is investigated. A dynamic model of the overhead crane was developed, where the crane system is assumed as a lumped mass model. Under the mutual effects of the sway motions of the payload

An Anti-Swing Closed-Loop Control Strategy for Overhead Cranes
Applied Sciences, 2018 The payload swing of an overhead crane needs to be controlled properly to improve efficiency and avoid accidents. However, the swing angle is usually very difficult to control to zero degrees or for it to even remain within an acceptable range because ...
