The invention discloses a device lifting device used for large-scale building site construction. The device comprises a motor, a deceleration torque increment mechanism, a lifting chain, and a device container. The lower side of the motor is provided with a fixed support. A side of the motor is provided with the deceleration torque increment mechanism. A side of the deceleration torque increment mechanism is provided with a connecting shaft sleeve. A side of the connecting shaft sleeve is provided with a power output shaft. One end of the power output shaft is provided with a fixed end cover. The power output shaft is provided with an upper reverse stop disk. A lower reverse stop disk is arranged under the upper reverse stop disk. Two sides of the lower reverse stop disk are provided with the lifting chain. The lifting chain is provided with chain latches. Two sides of the lifting chain are provided with telescoping supports. The device container is arranged under the telescoping supports. A chain slack adjusting knob is arranged on the upper part of the lifting chain. Since the low-voltage motor and the deceleration torque increment mechanism are used in a cooperative manner, the device can provide enough lifting force to lift up relatively weight device. The reverse stop disk is used to prevent weight from sliding down in a moving process. The device is safe and reliable.
