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.

Tech-Bulletin for MLTX Lower Case Update
This bulletin is generated as reference
and notice for those of you who have Telemotive MLTX systems
(either licensed or non-licensed). While the MLTX continues
to be one of the best transmitters on the market, some users
have had a problem with the battery post connections due to
over-tightening the battery hold down screws or thumb screws
when installing a new battery. Here is the solution to this
problem.

the bottom flange is not continuously welded to the web
material. |
