The invention discloses a lifting device and an aerial work platform, and relates to the technical field of engineering machinery. The lifting device comprises a plurality of fork frame units, each fork frame unit comprises two supporting rods, and the middles of the two supporting rods are in pivot fit, so that the two supporting rods are driven by the lifting driving mechanism to rotate around the pivot fit position, and lifting of the lifting device is achieved. According to the lifting device, due to the fact that each fork frame unit is matched in the pivoted mode through the two supporting rods, the overall weight of the lifting device can be reduced, the lifting device is applied to the aerial work platform, the gravity center of the whole machine can be kept at a low position, and therefore the stability of the whole machine is improved. Furthermore, the whole machine can realize lightweight design, and the manufacturing cost is reduced.
本申请公开了一种举升装置及高空作业平台,涉及工程机械技术领域。举升装置包括多个叉架单元,每个叉架单元均包括两个支撑杆,两个支撑杆中部枢转配合,从而在举升驱动机构的驱动下两个支撑杆绕枢转配合处转动,以实现举升装置的升降。本申请公开的举升装置中,由于每个叉架单元通过两个支撑杆枢转配合,所以举升装置的整体重量会减轻,应用于高空作业平台,可使得整机的重心保持在一个较低的位置,从而提高整机的稳定性。进一步可使得整机实现轻量化设计,降低制造成本。
