New
Telemotive MLTX 2 Transmitter Available Now!
With the success of the MLTX transmitter it
was only a matter of time until the MLTX was
updated to allow its usage in a wider range of
applications. The MLTX 2 transmitter is the next
generation of the MLTX transmitter, providing
the continued standard of a transmitter that
will hold up to almost anything. The housing is
again a polymer, super tough nylon case, and
using heavy duty motion switches that have shown
over 5 million operations in the field and more!

-or-
(Where do I mount my encoder?)
I recently had a
conversation with a man who is responsible for
many cranes both AC and DC. As a part of one
overhead crane modernization, he was moving from
a straight DC contactor control to an OmniPulse
digital drive control. The issue of how and
where to mount the encoder for feedback for the
hoist drive came up, and it reminded me to write
a technical bulletin. Now I am sure that some of
you saw the topic of this technical bulletin and
thought either I’ve lost my mind, or Engineered
Lifting Systems has entered into the real estate
business. Not so! I am only pointing out the
first rule of encoder installation.

U-S Safety Trolley Four-Bar Electrification use
with Gorbel Workstation Systems
This bulletin is
provided as a notice to provide information
regarding the use of U-S Safety Trolley
“Four-Bar” electrification on Gorbel Workstation
crane and monorail systems. Anyone
familiar with the Engineered Lifting Systems
website knows we are huge proponents for Gorbel
and Gorbel’s products. The term “Workstation”
for Gorbel pertains to their ergonomically
designed enclosed track and carriers for crane,
monorail, and jib systems. At the heart of these
systems for 150 up to 4,000-lb capacity are a
proprietary enclosed track and special polymer
wheel material mounted on precision bearings
providing ease of operation. Predominantly these
systems are applied for use with an electric
hoist, and are provided with flat wire festoon
systems for power conveyance offering the least
amount of drag and as such needing the smallest
amount of force to propel the trolley or bridge
motions.

Encoder Cable for Overhead Cranes
This bulletin is generated as
reference and guide to anyone who is using or
going to use encoder feedback on an overhead
crane in order to select the correct type of
encoder cable. Since a majority of
applications for encoder usage on an overhead
crane are on the hoist motion, this article
focuses on that specific application, although
much of the information is relative to any crane
application, or an application in general.

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.
