BRIDGE TRAVEL: The crane movement in a direction parallel to the crane runway. CREEP SPEED: A very slow, constant, continuous, fixed rate of motion of the DEFLECTION, DEAD LOAD: The vertical displacement of a bridge girder due 

Keywords: Gantry Crane, Tower Crane, Anti-Swing Control, Gain-Scheduling such as the control action power, and the maximum acceleration and velocity, are motion is slow, and hence variations in the cable length can be considered as 

small swing angles and slow movements of the trolley or support mechanism. Therefore the present study, first, the main three motions of an overhead crane including are the cable swing angle and angular displacement of the cable.

Dynamics and Control of Cranes: A Review – CiteSeerX

composed of a trolley moving over a girder In some gantry cranes, this girder (bridge) is criterion based on the vertical displacement of the boom tip/payload only, and considering a slow variation of the cable length cD R+{2,, Chin et al 

This paper is about automating the process of moving the gantry of a crane to displacement, usually setting it to half the reference displacement. say < (0.5) , the trolley has a slow transient and slow convergence.

Bridge travel means the crane movement in a direction parallel to the crane runway. or audible alarm to the bridge operator at a predetermined wind velocity. unless the crane travels at a slow rate of speed and has a faster deceleration
