The embodiment of the invention provides a crane, a hoisting device and a control method, a control device and control equipment of the hoisting device. Due to the fact that the first inverter is electrically connected with the charger and the lifting motor is electrically connected with the first inverter, when the power receiving interface of the charger is connected with the power source, the charger can supply power to the first inverter, and therefore the first inverter can supply power to the lifting motor. The hoisting motor can execute hoisting operation when being powered on, and the hoisting operation includes acting by overcoming the gravity of the first target cargo; in addition, the lifting motor can generate electricity under the gravity traction of the second target goods, electricity generated by the lifting motor is provided for the charger through the first inverter, and therefore part of electricity is provided for the lifting motor to execute the next lifting operation, the electricity consumption in the lifting operation process is effectively reduced, and the energy utilization efficiency of the lifting device is improved.
本发明实施例提供了一种起重机、吊升装置及其控制方法、控制装置和控制设备。由于第一逆变器与充电机电性连接,吊升电机与第一逆变器电性连接,在充电机的受电接口连接有动力电源时,充电机能够向第一逆变器提供电源,从而使第一逆变器向吊升电机提供电源。吊升电机能够在接通电源时执行吊升作业,吊升作业包括克服第一目标货物的重力做功;吊升电机还能够在第二目标货物的重力牵引下发电,并将发电电能通过第一逆变器提供给充电机,从而为吊升电机执行下一次吊升作业提供部分电能,有效减少了吊升作业过程的电能消耗,提高了该吊升装置的能源利用效率。
