AC & DC Drive Maintenance

Solid state electronic variable speed drives require regular maintenance. Replacing fans, torquing connections, cleaning and waveform checks can extend the operating life of equipment and reduce failures.

Our maintenance team of factory trained professionals can provide this service for all your drives—large or small.

Typically, our customers schedule a time when L&B can perform a maintenance sweep and at the same time document all their drives. Data is maintained and used to make subsequent visits even faster.

Call L&B today and find out how we can help you service your AC and DC drives and keep them running reliably.

Circuit Breaker Testing

Your circuit breakers protect you, your people, your equipment, and your plant. Do you know if they still work properly?

Circuit breaker testing can be an important due diligence requirement from a Health and Safety and Capital Equipment Insurance perspective.

We provide circuit breaker testing for many medium and large size breakers and load break switches. We document the performance of your gear and make sure it still is in compliance with its performance specifications.

Call today and find out how we can help you test your circuit breakers.

Dynamic Balancing

The best thing you can do to increase up-time, service life, production reliability, and safety is make sure your equipment is precision balanced.

Even small amounts of unbalance cause vibration and vibration is a major cause and predictor of equipment failure.

L&B is the leader in The Maritimes when it comes to precision custom dynamic balancing. Our equipment is the best available and we balance to the limits of its capabilities and to the very best of our abilities.

Allow us to help you maintain production as quietly, efficiently and safely as possible—with precision dynamic balancing.

Laser Shaft Alignment Services

Bearing life can be extended exponentially by proper precision shaft alignments.

L10 = bearing lifetime in million turns

C = a constant that depends on the bearing type

P = bearing load as the sum of radial + axial forces

Doubling the force reduces bearing life to 1/8th, 3 times the forces reduces service life to 1/27th of the original lifetime.

In addition to balancing, we pay close attention to shaft alignments.

Precision laser shaft alignments are a major factor for increasing long term reliability, reducing maintenance costs and reducing downtime.

Laser Alignment Benefits:

• Exponentially longer service life.
• Reduced power consumption.
• Reduced coupling wear.
• Reduced machine vibration.
• Reduced noise.
• Increased reliability means it saves you money!

Infrared Thermography

Vibration Analysis Monitoring

Vibration Analysis is a powerful tool we've used for over 22 years for quality assurance testing in our shop. We also use it extensively for predictive maintenance on our customer's machines.

Get started implementing a vibration monitoring program by calling us and booking a time. We will visit your plant and do baseline testing of all your critical motors.

Problems can often be spotted right away but the real power of your program manifests itself in subsequent visits. New data is compared to the baseline data of previous visits and trends are observed.

Using this and other predictive techniques you can catch motors that are trending towards failure ahead of time and take them out of service at your convenience (without impacting production).

Call us today and find out how we can help you save money and increase production.
