Hi all

Two points: The guard abve the driver in almost all cases is not a rollover guard (the mast prevents rolovers occurring) but a guard to prevent injury from falling objects when the forklift is being operated at height. In some cases people should review the guard from a safety perspective. And the tinned food industry is one of those. Can a heavy 1 kg or more tin fall from a pallet, especially in the pre-cartin stage, and through openings in the overhead guard. If so you need to install some mesh or acrylic sheet to remove that risk. I appreciate than numbers of manufactrurers have acrylic inserts/sheet that prevent any objects getting through the guard.

And the workcage: Buy one that complies with the ISO or other standards - but also read the standards and make yourself aware of the other requirements when workcages are being used. For example ISO / Australlian standards require:
For counterbalance forklifts the lated capacity of the forklift must be 1800 kg or 5 times the total weight of the workcage, plus workers, plus tools and other materials. And for reach truck the figures are 1000 kg or three times;
THe mast tilt control must be mechanically locked out;
The driver must stay at his post for the full time prople are in the cage; et cetera

So its not just the design of the workcage that is the issue
