(57) A hooking and moving frame of containers for front hoisting trucks the side arms
of which, extensible through two stages, for the hooking of the container can be drawn
back so that the maximum size of the frame, in the condition of maximum withdrawal
of the extensible arms, is reduced, consistently with the requirements of structure
strength, and does particularly permit the hoisting truck to pass through the loading
and stowage doors of container carrying vessels without removal of the hooking frame.
