POOR Product Quality Control. purchased a quick attach, 4000 lb, 48 inch pallet fork unit. Arrived in 2 or 3 separate shipments which wasn't an issue. The issue is the frame which holds the fork is welded WAY OFF from end to end allowing the left fork to literally fall of when raising the forks!! the right side is welded at 16 1/8 inch and the left is welded at 15 3/4, that's a difference of 3/8 inch!!! the top of the fork "lock" just slips off over the rail! I purchased this unit on 8/26/23 (today is 5/30/24) and have RARELY used them other than on a pallet with narrow fork openings a couple times! I guess my only advice is to be the quality control person yourself and inspect upon delivery because I sure missed it, was not noticeable until TODAY while trying to use with both forks all the way out.
