1 engages the containers 5 a and 5 b at extreme corners 11 a to d and internally at the internal corners of the containers 5 a and 5 b each through twist lock engagements it will be appreciated that the following description is equally applicable to spreaders having engagement with single containers and in fact applicable to other types of freight lifting devices mounted to the spreader 1 is a frame 10 as shown in fig2 the frame 10 is mounted within a void 30 defined by a u201c cage u201d formed from the spreader 1 above containers 5 a and 5 b below and the twist lock engagements 15 a to d and 16 a and b thus the frame 10 lies wholly within the void in spaced relation from the containers 5 a and 513 so as firstly not to interfere with any extraneous object and further to not interfere with the connection between the spreader 1 and the containers 5 a and 5 b thus it will be seen that because the frame 10 is placed in position so as not to interfere with the connection between spreader 1 and containers 5 a and 5 b the flippers 15 at each corner of the spreader can be of a conventional type and not overly elongate to accommodate the inclusion of an intermediate frame the frame 10.
