The invention discloses a lifting device for a field electric tower. The lifting device comprises a tower body. An upper chain wheel device is installed at the top of the tower body, a lower chain wheel device is installed at the bottom of the tower body, and the upper chain wheel device and the lower chain wheel device are connected through a chain. The tower body is further provided with a tensioning device which is used for tensioning the chain. Support frames are installed in a pair on the outer walls of the tower body. Sliding chutes are formed in the support frames. A roller assembly isinstalled on the chain. The roller assembly comprises a connecting shaft and two rollers. The connecting shaft transversely penetrates through the chain, and the two rotatable rollers are installed atboth ends of the connecting shaft. The two rollers are respectively located in the corresponding sliding chutes. Installation sleeves sleeve both sides of the connecting shaft. A support box body isinstalled on the installation sleeves. A handholding device is installed on the chain, and the handholding device is located on the chain above the support box body. According to the lifting device for the field electric tower, the lifting of people or objects is realized, going up and down the tower body is convenient for construction personnel, and the time for the construction personnel to go up and down the tower body is saved. The lifting device is stable and reliable, and is high in safety.
