TESTING THE 4-WAY
The BUZZBAR 4-Way pallet puller & turner was designed specifically to work with 4-way entry ( notched ) stringer pallets and 2-way entry stringer pallets. It is conservatively rated at 3200 lbs. pulling loads over smooth truck bed floors.
In testing with a lift truck, a proof coil chain, a 10 mm Quick Link chain connector and a full spec. 48 inch x 40 inch GMA pallet, the BUZZBAR 4-Way turned and pulled 6136 lbs. of steel coil across a smooth cement floor. That's 191% of the pullers rated load capacity. See Video of test and picture below.

When test pulling with a 6136 lb. weight load, the only signs of stress to the new pallet was an .030" impression created where the puller made contact to the lower deck board edge and under the stringer board where the cradle hex. head, left its impression from trying to rise up and pass between the stringer board and the lower deck board. This demonstration
At the 3200 lb. pulling the BUZZBAR 4-Way pallet puller displayed no significant signs of wear or stress.
For handling extra large stringer pallets with extremely heavy weight loads you can use 2 pullers at the same time linked together with a short chain as shown above.
The BUZZBAR 4-Way :
BUZZBAR pallet pullers are to be used with proof coil chain and not to be used for lifting. For maximum pulling with minimum chain weight we recommend 5/16" proof coil chain.
