The invention provides a variable-amplitude trolley and a tower crane, and relates to the technical field of engineering machinery. The variable-amplitude trolley comprises a frame, rollers and a power generation device; the roller is mounted on the frame, and when the frame moves relative to an arm support of the tower crane, the roller is used for being in contact with the arm support; the idler wheels comprise target idler wheels, and the target idler wheels are connected with the power generation device and used for driving the power generation device to generate power. When the variable-amplitude trolley is driven by the variable-amplitude driving mechanism such as a winch to move on the arm support, the power generation device can be driven to generate power through rotation of the rollers relative to the frame, so that power can be supplied to electric components such as a monitoring system arranged on the frame, and the variable-amplitude trolley does not need to be moved to a specific position to be charged; the endurance performance of the variable-amplitude trolley can be improved, and the reliability of continuous operation is guaranteed.

    本发明提供一种变幅小车及塔式起重机,涉及工程机械技术领域。变幅小车包括车架、滚轮和发电装置;所述滚轮安装于所述车架上,当所述车架相对于塔式起重机的臂架移动时,所述滚轮用于与所述臂架接触;所述滚轮包括目标滚轮,所述目标滚轮与所述发电装置连接并用于带动所述发电装置发电。变幅小车在变幅驱动机构例如卷扬的驱动下在臂架移动时,可通过滚轮相对于车架的转动带动发电装置进行发电,从而可以为设置于车架上的监控系统等用电部件进行供电,而无需将变幅小车移动到特定的位置进行充电,可提高变幅小车的续航性能,保证连续作业的可靠性。
