Are you looking for an ISO container lifting machine? ISO container lifting is designed to connect to the top, side, or bottom of a shipping container so that the container can then be lifted by an overhead crane. ISO Containers (International Organization for Standardization) can be lifted by a chain sling, a spreader beam, or a lifting beam though always as per the manufacturer's operation and user manual. At some point it is hard to move the containers, power pusher helps in that case.
