The hoist was otherwise in generally good shape, and because
of its special design, it would be very difficult to replace
in this application.
So, Engineered Lifting Systems
worked out a modernization plan based around a Magnetek VG+
Series III drive, locking the load brake so the drive would
handle the dynamic lowering chores with feed back via a
Lakeshore 1024 PPR encoder, shaft mounted to the existing
motor.
This
design allows the customer flexibility to update the motor
at a later date if required.
Controls
were modernized, including load reactors to protect the
existing hoist motor due to it’s age.
With these components delivered in only a few days to the
customer, total downtime was limited to days, not weeks or
months!
The
hoist was placed back in service, and the only complaint has
been:
“We can’t hear the hoist
operating any more."
When you have a crane or
hoist in need of repair or a makeover, extreme or otherwise,
don't wait weeks or months for factory replacement parts.
Call the crane doctors at Engineered Lifting. We make
house calls.

assistance with your crane, hoist and engineered lifting
requirements, please contact Eric
