The invention provides a lifting device and a crane. The lifting device comprises a connecting part, a bearing part and a transmission part. The connecting part is used for being connected with a counterweight bracket of the crane; the bearing part is used for bearing workers; the transmission part is used for controlling the bearing part to rise to a first target position so as to be close to a climbing starting point of the counterweight bracket; and the transmission part is also used for controlling the bearing part to descend to a second target position so as to be close to the ground or contact with the ground. Through the lifting device, a worker can conveniently reach the position above the cargo boom; moreover, the device is not influenced by a site and the shape of the crane, and can quickly return to the ground, so that the climbing strength is reduced.

    本发明提供了一种升降装置和起重机,该升降装置包括连接部、承载部、传动部。连接部用于与起重机的配重托架连接;承载部用于承载工作人员;传动部用于控制承载部上升至第一目标位置,以靠近配重托架的攀爬起点;并且,传动部也用于控制承载部下降至第二目标位置,以靠近地面或与地面接触。通过该升降装置,工作人员能够便捷地到达起重臂上方;而且,不受场地和起重机自身外形的影响,能够快速地回到地面,减少攀爬强度。
