You can tell who really are the "World Leading Manufacturers" by simply seeing what "Technical & Safety Support" they provide to fellow industry companies - the professional ones readily supply info and the others fail miserably! I recently tried to get a new revised Rating from a so called World Leading Manufacturer (Hyster Yale) on a Used Truck that we are fitting an attachment to and are still waiting after 2x weeks - what a joke... Their competitors usually return the same within 24 hours - I will not be buying anymore Trucks from such poor suppliers again!
