[0012] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0013] like Figure 1-3As shown, a single-point electric remote control container lifting device includes a lifting device body 1, a connecting seat 2 is provided in the middle of the lifting device body, a battery pack 3 is installed in the middle of the connecting seat, and the battery pack is used to power a hydraulic station 4. The hydraulic station is installed on the lifting device body, and a rotary lock 5 is installed at the four angles of the lifting device body. A hydraulic motor 6 is installed on the upper part of the rotary lock, and the hydraulic motor is driven by the hydraulic station. The hydraulic motor drives its upper guide plate 7 to rotate, and the guide plate is driven by the hydraulic motor to rotate to limit the container. When the lifting device needs to lift the container, the lifting device is on the upper part of the container, and the four guide plates are opened at a certain angle. The lifting device slowly moves downward, and the container is aligned with the lifting device under the action of the guide plate. After the lifting device is buckled onto the container as a whole, the rotary lock is locked into the lock hole on the container. The rotary lock in the present invention adopts the existing structure, and the driving method adopts electric drive. The present invention drives the hydraulic cylinder to lock the box, lock the box, and open the box by means of lithium iron phosphate batteries and three-phase asynchronous motors. The motor starts smoothly, has low noise, and comes with self-protection. The spreader body is equipped with a wireless transceiver 8. A rotating gear ring 9 is provided between the connection seat and the spreader body. The spreader can be electrically remotely controlled to achieve the matching, locking and unloading of containers. The efficiency of loading full containers is expected to be increased to 15 containers / hour, and the efficiency of unloading empty containers is expected to be increased to 20 containers / hour.

[0014] Step 1: Start the inverter The inverter and battery are connected using a quick plug. Before starting the inverter, Please connect the plug to the socket of the lithium battery first.
