The invention relates to the technical field of auxiliary devices for portal crane, in particular to an anti-shake portal crane. The invention provides an anti-shake portal crane capable of increasing the friction force between the portal crane and the ground. An anti-shake portal crane comprises a cross beam, two supporting frames, steel wheel frames, an operation room, a windward mechanism and the like, the two supporting frames are arranged front and back, the steel wheel frames are connected to the left side and the right side of the bottom of each supporting frame, the cross beam is connected between the tops of the two supporting frames, and the operation room is slidably connected to the cross beam; a windward mechanism for pressurizing the cross beam is arranged on the cross beam. The friction frame between the two air cylinder telescopic rods moves downwards and can make contact with the ground, so that the friction force between the crane and the ground is increased, the crane can be prevented from shaking, and then the stability of the crane is improved.
本发明涉及门式起重用辅助装置技术领域,尤其涉及一种防抖式门式起重机。提供一种能够增加门式起重机和地面的摩擦力的防抖式门式起重机。一种防抖式门式起重机,包括有横梁、支撑架、钢轮架、操作室和迎风机构等,支撑架的数量为两个,两个支撑架呈前后设置,支撑架底部左右两侧均连接有钢轮架,两个支撑架顶部之间连接有横梁,横梁上滑动式连接有操作室,横梁上设有用于加压横梁的迎风机构。本发明两个气缸伸缩杆之间的摩擦架,摩擦架向下移动能够与地面接触,从而增加本起重机与地面的摩擦力,如此能够防止本起重机发生抖动,进而提高本起重机的稳定性。
