Lifting machine and lifting system

The utility model relates to the technical field of lifting equipment, and provides a lifter and a lifting system.The lifter comprises a lifting body, two first guide rails, two door plates and at least two first pulley assemblies, and the two first guide rails are arranged on the lifting body side by side; each door plate is arranged corresponding to one first guide rail; the at least two first pulley assemblies are arranged on the end faces of the two door plates correspondingly, and the at least two first pulley assemblies slide along the two first guide rails correspondingly. The defect that a single guide rail easily affects normal sliding of door plates in the prior art is overcome, and two door plates can be guided and slide through double guide rails respectively. 本实用新型涉及升降设备技术领域，提供一种升降机和升降系统，该升降机包括升降主体、两个第一导轨、两个门板及至少两个第一滑轮组件，两个所述第一导轨并排设于所述升降主体；每一所述门板对应一个所述第一导轨设置；所述至少两个第一滑轮组件分别设于两个所述门板的端面，且至少两个所述第一滑轮组件分别沿两个所述第一导轨滑动。解决了现有技术中单导轨容易影响门板正常滑动的缺陷，实现双导轨分别导向滑动两个门板。
