Abstract
Abstract Handling devices for use in containerized transport systems are adapted for temporary but rigid attachment to the ends of a container. Each device comprises a frame provided with (a) locking devices to engage the standard ISO castings or like fittings of the container, (b) power-operable extending legs with feet, which legs can be extended into ground contact and lift the container to permit loading on to a vehicle or off-loading, and (c) sockets for engagement by the prongs of a fork-lift machine to facilitate handling of the device when being fitted to or removed from the container.
