The alignment of machine trains can be a lengthy task. In the past, alignment data of the entire machine train had to be manually graphed to scale in order to determine the optimal moves. The ROTALIGN ULTRA laser alignment tool can now instantly graph the alignment results of an entire machine train of up to fourteen machines to scale—maximizing efficiency and minimizing frustration. You can optimize an alignment centerline through a machine train to minimize corrective moves everywhere. Forget graph paper!” —Pedro Casanova, Manager of the Alignment Division – LUDECA, Inc.
The Machine Train Alignment Crash Course Video provides background knowledge along with tips and procedures for efficiently completing the alignment of multiple-element drives using laser alignment equipment.

Too often management remembers the unanticipated machine failure of three years ago rather than the dozens of prevented failures that did not occur since that event. The challenge to maintenance and reliability teams is how to keep their successes in the forefront of management’s mind. I have visited a large number of plants and factories over the years and one of the most effective tools I have ever seen is a trophy case. These display cases are most often located in hallways where plant personnel walking by can see the displayed saves. Often they will show a cut-away of a bearing or gear showing slight damage. The background often includes graphics indicating the amount of saved production time or saved cost when compared to breakdown maintenance.
One paper mill had a cutaway of two bearing raceways that both appeared to be normal. The accompanying background included pictures of the raceways taken with a stereo microscope. It showed a magnified picture of the good bearing in contrast to the bad bearing, which had looked good to the naked eye. The differences in the pictures were striking. The message was, we know what we are doing and this is real science, not guesswork, thereby proving that we provide value. Displaying your SUCCESS stories where everyone can see them will help paint a positive and progressive image of your reliability team. When they think of your program, they should think SUCCESS!

If you are a vibration analyst or are responsible for managing a Condition Monitoring (CM) program or reliability effort, you are probably keenly aware of the “what have you done for me lately” mentality. This is a mentality that may frustrate us somewhat, but if we think about it, it is only natural. In fact, if we are honest with ourselves, we will probably find we apply the same mentality to others at times.
This being the case, it is very important that we keep our management team apprised of the value they are getting from us, our tools, and our training. This is not a personal pride thing, but simply a part of business operations. Corporate management reports regularly to stock-holders, showing the value of their management. Investors are willing to maintain their investment in a company, so long as they know they are getting a valuable return on their investment. In the same way, management will be willing to sustain their investment in CM along with its practitioners and equipment, as long as they are aware they are getting ample value in return for their investment.
CM efforts provide direct and positive contributions to key indicators like reduced downtime, reduced repair costs, reduced parts inventory need, increased production capacity, etc. If tracked correctly it will be clear to management that CM provides a big return on investment (ROI). Do not hesitate to bring Management’s attention to the many ways that CM contributes to the business goals of your facility or corporation.
Many companies are so accustomed to the CM department detecting unbalance in fans and the like, and then driving the remediation of the problem (via cleaning, repair and field balancing) that they no longer appreciate the value of such things. If the CM manager is not careful, he may find himself wondering what happened, because he took it for granted everyone appreciated the value of the CM contribution to the bottom line, only to find out some of his people (or even himself) are seen as expendable because the value of their work is not fully appreciated. In this era of downsizing and “leaning up”, this is a chance no one should take. Document the actual savings in parts, labor, lost production and downtime that you generated with your CM successes by averting the potential failures that would have occurred without your efforts.

Soft foot is every alignment technician’s worst nightmare and while correcting soft foot may not be easy, it is worth every minute you spend on it, because once done, the alignment of the machines becomes a much easier task. If you want to make aligning your machinery easier, quicker and more accurate, start by correcting soft foot.” —Alan Luedeking, Manager Tech Support – LUDECA. Inc.
The Soft Foot Checks and Corrections Crash Course Video provides insights and instructions on solving various types of soft foot, and demonstrates industry-leading techniques using laser alignment equipment.

The ROTALIGN ULTRA laser system with Continuous Sweep allows turbine coupling checks with two measurements to be completed in as little as 6 minutes instead of 6 hours. The time savings can be further increased by using multiple laser systems for each coupling and having them start at the same time.”
Slashing Time on 16-Point Turbine Coupling Alignment Checks
ENERGY-TECH • April 2013
A power turbine consists of multiple rotors that are joined by couplings. A critical point in the service of a turbine is the coupling check. This check determines the position of the two faces of the coupling with respect to each other.
A “16-point check” has been the standard measurement method for verifying this coupling alignment. In its core form, it is like the “rim and face” check used in standard dial indicator alignment.
The rim readings are measured by a dial indicator that indicates along the edge of the coupling. This reading verifies the offset at the center of the shafts at the coupling point (providing of course that the coupling hubs themselves are not out-of-round or eccentric to the shaft centerline.)…
