The invention relates to the field of engineering machinery, and discloses a crane power system, a control method and a tire crane, the crane power system comprises a loading hydraulic system and a braking hydraulic system, and the crane power system further comprises an engine, a gearbox, a main oil pump, a power takeoff, a power takeoff oil cylinder and an oil cylinder control system, the main oil pump is used for pumping a hydraulic oil pump of a hydraulic oil source to the loading hydraulic system, the power takeoff is connected with the gearbox and the main oil pump, the power takeoff can be switched between an off state and an on state under the driving of the power takeoff oil cylinder, the oil cylinder control system comprises an oil inlet oil way, and the oil outlet end of the oil inlet oil way is connected with the power takeoff oil cylinder; and the oil inlet end is connected with a brake hydraulic system. Oil consumption of the crane in the running process is effectively reduced, the running capacity of the crane is improved, the service life of the main oil pump is prolonged, and the problem that an engine is difficult to start when the environment temperature is low is solved.

    本发明涉及工程机械领域,公开了一种起重机动力系统、控制方法及轮胎起重机,起重机动力系统包括上车液压系统和制动液压系统,起重机动力系统还包括发动机、变速箱、主油泵、取力器、取力油缸以及油缸控制系统,变速箱与发动机连接,主油泵用于将液压油源的液压油泵送至上车液压系统,取力器与变速箱和主油泵连接,取力器在取力油缸的驱动下能够在断开状态和接通状态之间切换,油缸控制系统包括进油油路,进油油路的出油端与取力油缸连接,进油端与制动液压系统连接。本发明有效降低起重机在行驶过程中的油耗,提高起重机的行驶能力和主油泵的使用寿命,避免在环境温度较低时发动机的启动较为困难的问题。
