The invention provides a method for relieving shaking of a cover plate of a large lifting platform. The method comprises the following steps that the cover plate of the lifting platform is opened; when the cover plate is opened to a preset angle, the movement speed of the cover plate is controlled to be slowly reduced; when the cover plate is nearly opened by 90 degrees, the speed of the cover plate is close to zero. The large lifting platform can be stably folded and unfolded, shaking noise can be eliminated, equipment abrasion is reduced, meanwhile, a hydraulic oil cylinder of equipment is protected, excessive stress of the hydraulic oil cylinder is prevented, and the service life of the hydraulic oil cylinder is guaranteed.

    本发明提出了一种减轻大型升降平台盖板晃动的方法,包括以下步骤:升降平台的盖板开启;盖板开启到预设角度,控制盖板运动速度慢慢降低;盖板在接近打开九十度时,盖板速度接近于零。本发明能够使大型升降平台平稳收放、可消除晃动噪音、减少设备磨损,同时对设备的液压油缸起到保护作用,防止其受力过度,保证其使用寿命。
