COLUMBUS McKINNON CORPORATION

First introduced in 1955, the CM® Lodestar® was engineered to be the best electric
chain hoist in the world. Developed through meticulous engineering and American
manufacturing know-how, we weren’t interested in building a hoist that merely
performed, we wanted to create something extraordinary.

Lodestar – iconic in name and legendary in performance – is recognized as the
standard in the overhead lifting industry. Generations of professional riggers
have come to rely on the CM Lodestar for the most demanding and challenging
applications. For this reason, we’ve never stopped reinventing and improving
it to satisfy the needs of every customer – that’s the cornerstone of how we do
business and part of our commitment to excellence.

Made in the USA, the Lodestar features quiet operation, an environmentally friendly
design, easy access to key components, high duty cycles, less maintenance
and enhanced safety features. Every Lodestar is designed, built and tested
to our exacting standards that not only meet, but surpass industry requirements.

Available as individual units, in hoist/trolley combinations, or as integral
components of complete lifting systems, the Lodestar takes lifting to
new heights for professionals in any industry.

With a history of unsurpassed performance and over a million units sold,
the next generation of Lodestar continues this legacy.
