The invention provides an arm type lifting machine. The arm type lifting machine comprises a support. A rear arm is hinged to the support. A front arm is hinged to the rear arm. A weight hanging device is arranged at the end of the front arm. The rear arm and the front arm are connected through a section plate I, and the front arm and the weight hanging device are connected through a section plate II. The rear arm is composed of a connecting bar I and a connecting bar II, so that a four-bar mechanism is formed by the connecting bar I, the connecting bar II, the support and the section plate I. The connecting bar I and the connecting bar II are parallel and are the same in length. The front arm is composed of a connecting bar III and a connecting bar IV, so that a four-bar mechanism is formed by the connecting bar III, the connecting bar IV, the section plate I and the section plate II. The connecting bar III and the connecting bar IV are parallel and are the same as the connecting bar I and the connecting bar II in length. A chain wheel set is arranged on the support and the section plate I and driven by a chain, and a power mechanism is arranged below the support. One end of the chain is connected with the power mechanism, the other end of the chain passes through the chain wheel set to be hinged to the section plate II, and then the power mechanism controls the rear arm to be linked with the front arm. The four-bar mechanisms work in a linked mode, and the arm type lifting machine is stable in structure and high in lifting efficiency.
