The invention relates to the technical field of hoisting equipment, in particular to a self-propelled trolley and a crane. The self-propelled trolley comprises a running mechanism, a frame, a hoistingmechanism and an energy supply device. The running mechanism is arranged on the crane and can move relative to the crane. The frame is connected with the running mechanism. The hoisting mechanism isarranged on the frame. The energy supply device is arranged on the frame and is electrically connected with the running mechanism and the hoisting mechanism. By means of the self-propelled trolley, the power supply manner to the crane trolley is improved, power supply manners of drag chain cables or drag chains or slide wires are omitted, complexity of a power supply circuit is reduced to the largest degree, and the difficulty of circuit maintenance and repair work is reduced.

    本申请涉及起重设备技术领域,尤其是涉及一种自行式小车及起重机,自行式小车包括:运行机构、车架、起升机构以及供能装置,其中,运行机构,设置于起重机,且运行机构相对起重机能够运动;车架与运行机构相连接;起升机构设置于车架;供能装置设置于车架,且供能装置分别与运行机构、起升机构电连接。本申请提供的自行式小车改善了对起重机小车的供电方式,取消了拖令电缆、拖链或滑线等供电方式,最大程度上减轻了供电电路的繁琐性,降低了电路检修、维修工作的难度。
