Tech-Bulletin for P&H Equalizer Sheave Failure
This bulletin is provided as a notice to inspect and possibly modify any existing P&H Balance Design hoist using a cotter pin as a retaining method for holding the equalizer pin in place.
Years ago, these pins were always provided with a two bolt keeper plate with a slot in the end of the equalizer pin with a grease fitting to lubricate the equalizer sheave bearing. However, at some point in time the keeper plate was replaced with the cotter pin, and no lubrication.
