The invention provides a lifting device, a balance weight loading device of the lifting device and a detection method for the load of a balance weight. The balance weight loading device comprises an installation beam and a piston cylinder arranged on the installation beam. A piston rod of the piston cylinder penetrates the installation beam. The piston rod is provided with a balance weight connecting part. The balance weight loading device further comprises a main detection part arranged between the piston cylinder and the installation beam and used for detecting the pressure between the piston cylinder and the installation beam, and an auxiliary detection part arranged between the balance weight connecting part and the installation beam and used for detecting the pressure between the balance weight connecting part and the installation beam and/or the position of the balance weight connecting part. The balance weight loading device detects the pressure between the piston cylinder and the installation beam through the main detection part, the part of pretightening force of the balance weight in a pressure value detected by the main detection part can be quantized, and therefore the balance weight loading device can accurately obtain the load of the balance weight through coordination between the main detection part and the auxiliary detection part.
