Analysis of The Principle of Stable Hook of Gantry Crane
Analysis of The Principle of Stable Hook of Gantry Crane
1.When the swing of the crane, to find ways to make the crane to achieve a relatively balanced state, should be through the control of the size of the car to achieve the effect of the balance of the crane, which is the most basic skills of the operator of the stable hook operation, and the reason why the size of the car for control, because the important reason for unstable lifting is that when the big car or trolley running mechanism start, because this process is suddenly By the static into a state of motion, the big car start back to produce transverse swing, the small car will produce longitudinal swing, if it is started together, it will produce oblique swing.
2.When the steady hook operation, the amplitude of the swing is big but the end of the swing back to the moment, to put the car to follow the direction of the hook swing. When the hook and wire rope pulled into a vertical position, then the hook or hoist will be subject to the action of two balancing forces, will be rebalanced down to keep the speed of the car and hoist the same speed and then together with the forward movement, will be able to maintain relative stability.
3.There are many ways to stabilise the hook for the crane, and each has its own operating principles and techniques, there is a stable hook in motion, there is also a stable hook in place, that is, when the crane is in place, the amplitude of the hook swing for appropriate crane, reduce the inclination of the wire rope, this method is not only able to be used in the crane in situ, that is, in the crane's movement, it is also applicable to the same, known as the start of the stable hook.
