Heavy Duty Crane in Action

Why would you weigh a 225 ton power generation rotor unless you really have a good reason? The answer, the exact weight is very important to the safety of everyone working at the Beaver Dam power house.

The in-house bridge crane system at Beaver Dam has a maximum rated lifting capacity of 450,000 pounds. According to the American Society of Mechanical Engineer guidelines, a crane is limited to two lifts in excess of the maximum rated lift capacity in a 12 month period. If the rotor and lifting beam weighed less than 450,000 pounds, the team in the Beaver Dam power house would be able to proceed with the rehabilitation of their bridge crane. The only problem…a mechanical drawing for the crane and beam stated the total weight at 455,000 pounds.

To guarantee safety, a team from across the Little Rock District was assembled to weigh the massive rotor. They placed four jacks within an 8 foot diameter around the erection bay pedestal to raise the rotor. This diameter keeps the load directly over the concrete column that was designed to support the tremendous weight. Scales were placed between the rotor and the jacks. The large bolts that attached the rotor to the pedestal were loosened. The rotor was picked up and weighed twice. The measured weight with the lift beam was 449,320 pounds, which is just under the crane’s rated capacity.

The team records the final weight – 449,320 pounds. That is just under the crane’s maximum rated lifting capacity of 225 tons. Photo by Julie Ann Massey.

Now that the team has an accurate measurement and the total weight is below 225 tons, the bridge crane rehab can proceed and the crane will provide years of safe and reliable service in the power house.

Leadership Development takes Center Stage

The Little Rock District’s Level Two Leadership Development Program class of 2017 completed their year-long endeavor toward greater leadership opportunities with their graduation event Feb. 1.

Little Rock District’s Level 2 Leadership Development Program Class of 2017 celebrate after their graduation ceremony Feb 1. Class members are: (top row, left to right) Michael Ellis, Kevin Patterson, Caleb Young, Michael Worthington, Lee Kirkpatrick, Dylan Edwards, and Miriam Thomas, (front row, left to right) Frank Jordan, Jessica Foiles, Liz Anderson, Siobhan Fabio, Amanda Kovak, Raven Coleman, and LaTasha Braggs.

The program’s director, DeAnn Lehigh encouraged the graduates to take what they had learned from this experience and continue to grow personally and professionally.

“Be yourself and be great at yourself,” said Lehigh. “Leadership is a calling…lead where you can.”

Level two LDP provides participants with experiences designed to increase self-awareness and understanding of their personal strengths and potential for leadership. The program’s objectives are to allow employees to learn about the U.S. Army Corps of Engineers; to expose them to leadership principles; and to gain team-building skills.

Little Rock District’s Level 2 Leadership Development Program Class participated in a “ropes” course to help build confidence.

“These graduates have shown they are life-long learners,” said Col. Robert Dixon, Little Rock District Commander. “During your LDP session, you were challenged to think. You had the opportunity to think about different things and look at problems from different angles. Now I challenge you to look critically at the things we do every day and find new solutions to our everyday problems.”

Colonel Dixon, the keynote speaker for the event, went on to stress the importance of relationships formed during learning opportunities like LDP2.

“Relationships matter. The relationships you have formed will serve you well in the future. I look back on relationships I formed over the years during numerous Army training opportunities. These relationships proved most valuable time and time again throughout my career.”

Little Rock District’s Level 2 Leadership Development Program Class works on balance and teamwork prior to the “ropes” course.

He closed his keynote remarks with two stories of personal relationships helping accomplish the Army’s mission and a challenge for each of the graduates.

“Take advantage of opportunities. This was a great opportunity and I know you took full advantage of each session over the last year. If you pass up an opportunity to challenge yourself, you may never know what you may have missed out on in your career.”

And with that, each of the 14 graduates stepped-up to receive their diplomas, a hearty handshake, and congratulations for completing another step of their life-long learning journey.
