Magnetek Crane Modernization Big Bang for the
We love nothing better than to
completely modernize an existing crane to gain
lower maintenance costs and more production. But
sometimes the demands of the business means that
improvements must be segmented in order to
optimize capital. On this project, the customer
was faced with just that problem so Engineered
Lifting Systems went to work on getting the end
user the most “Bang for the Buck”.

Existing Crane Cab gets a
If you have an old crane cab and it is no longer
providing the line of sight, or a less than
optimal ergonomic condition for your operators
there may be hope. Recently, a project
extensively using J.R. Merritt products was
completed to provide the operators of this ladle
crane a better view of operations, as well as a
more comfortable environment.
The old controls for the four motion crane were
the old “trolley controllers” for this 250 VDC
crane, lined up in front of the cab glass.

Temperature Limits for Series 3 Drives Case
Magnetek has announced that the
Impulse®●VG+ and Impulse®●G+ Series 3 drives are
now rated to 60° C, or 140° Fahrenheit as
standard. You might ask, “What’s changed?”. The
answer, nothing has changed. These drives were
already known as the best chassis in the
material handling business, but real world
experience has shown that these drives can hold
up to more than other ...

Brakes Applications Case Study
Because of the
flexibility and reliability of the
Mondel Thruster brake, we tend to overlook
the applications that suit the Mondel DC MBE
The 300 Series Mondel MBE DC shoe brake was
originally the P&H manufactured SBE shoe brake.
Mondel has been manufacturing the MBE for many
years now, and the MBE is a direct replacement
for the SBE unit.

New Steel Service
Center Crane Installation Becomes “Bushman AvonTec Showcase”
Engineered Lifting Systems has just finished
the installation of three Class D 90’-0” span overhead
cranes including a 55-ton, a 30-ton, and a 10-ton capacity.
While the scope of the project and the type of equipment is
impressive to start (Class E hoist units, A-4 bridge drives
with horizontally split gearboxes, cab on trolley, and
more..), the steel service center became a showroom for
Bushman AvonTec equipment.

Replace old Hydraulic Brakes
If your company has cab operated
cranes, chances are you have hydraulic brakes
for at least the bridge motion. Because of the
line of sight for a cab operator, and in some
cases the type of load, a cab operated crane is
the only way to go for some cranes. The operator
looking for that “seat of the pants” feel from
the crane control scheme and crane braking,
often mandated a contactor stepped or Static
Stepless control with a hydraulic foot operated

Provide Continuous Severe Service
Only a few short years after
purchasing a new 65/20-ton Class F Molten Metal Overhead
Crane, the customer could no longer suffer the downtime and
costs involved caused by the Square D variable Frequency
Drives. Being familiar with Magnetek Controls and Service,
the customer requested we develop a plan to replace the
Square D drives with Magnetek Series 3 drives.

Telemotive Announces the XLTX Transmitter
While on a trip to Magnetek
last week I was able to see the completely
new transmitter offering that will soon be
available from Telemotive, the XLTX. After Magnetek’s purchase of
Enrange, the engineering department at
Telemotive was able to create a fusion of
technology from both Telemotive and Enrange
to create a radio transmitter like no other.

Let’s face it, everyone loves Magnetek variable
frequency control. Whether it’s for a hoist,
trolley, or bridge motion, everyone likes the
managed and controlled ramp-up/ramp-down that
variable frequency provides, not to mention the
benefits from reduced mechanical parts wear.
But there is one person in a plant that does not like standard
variable frequency control on his bridge, and that’s the crane cab
operator. The crane cab operator wants to be able to control the
performance of the crane, and does not like a linear rate of
acceleration and deceleration.

Engineered Lifting Systems,
From Design to Installed in 2 weeks
Recently Engineered Lifting Systems was
contacted by a customer just over the Mississippi River with a
crisis. They were awarded a large contract that necessitated the
immediate expansion of their manufacturing capabilities, including
the need for additional cranes. In response to the dilemma ELS got right to
work! Over Easter weekend we worked with the customer and developed
Gorbel Workstation system arrangements using AutoCAD and the
customers building outline. The order for multiple Workstation crane
systems was ready for order entry on Monday morning.

We recently completed a project for
five 25-ton Class D cranes for a Mid-west steel processing center,
provided with Ace World trolley/hoists, and of course complete
Magnetek control panels using Telemotive radio remote controls.
After talking to the plant manager and personnel we were not
surprised to get comments such as “the hoist unit is so much bigger
than our old cranes”, and “the control of the cranes is quiet and

years, AC crane users have enjoyed the benefits of Magnetek variable
frequency crane controls, giving them low operating costs and
lowering mechanical costs due to high starting and stop forces on
the crane. Traditional AC contactor based controls just do not
provide the features and trouble shooting characteristics of a
Magnetek VFD drive. But what about you DC guys? Saddled with old magnetics, series or
shunt DC motors operating at rpms that impede or prevent conversion
to AC squirrel cage motors, with arcing contact tips, high inrush,
gearboxes sized for the motors making your life a nightmare? Not

Replacement of Existing Boom
Winches with Ace World Companies Winches and Magnetek Controls
Engineered Lifting Systems was contacted earlier this year to
design, propose and provide a pair of new boom winches for unloading
barges. The old booms were being upgraded to heavy units, and the
old winches would not be adequate for the increased capacity. The
requirements for the winches were 123 fpm line speed with a static
load of 12,000 lbs AND fit each winch into a very small footprint.

30-Ton Overhead Crane Gets New
During a recent service inspection, Engineered

four girder connections were cracked or broken from years of
service, as well as resulting cracks in the girders.

Hoist Control with Ace World Trolley-Hoists
Lifting Systems completed a multiple crane project for a large
Midwest steel supply company. The cranes are used for the loading
and unloading of many different sizes, shapes and bundles of steel
from trucks and rail cars. The cranes are primarily operated by cab,
and at times during the day the speed at which these cranes can
perform becomes critical when dispatching trucks to their customers.

Magnetek Crane Modernization for Coil
After securing emergency parts from Germany
for a new customer (see

selected to put two 25-ton cranes back into active coil
handling service for them.
Crane Control Panel Installation The Right Way
In the world of Material Handling, it is always a good idea
to look for and specify name brands for the equipment we
need. Names like Magnetek, Gorbel, Mondel, Yale and others
tell you that you are getting a product made by a company
committed to providing the best equipment.

had one 30-ton crane), and that the only thing keep them
from running was an OEM coupling
