Session Descriptions

ESA Sessions

Engineering Safety Factors for Hydraulic Cylinders

Hydraulic cylinders are unique among hydraulic components in that they also function as structural components of the machine.  Therefore, in additional to burst failure from internal pressure, they are also subject to structural failure modes.  Calculations can be used to predict common failure points and ensure adequate safety factors to prevent failure.

Cylinder Synchronization – Keeping it Together

A variety of common and unique strategies which are used to synchronize hydraulic cylinders will be presented, both low-tech and high-tech. You will learn why synchronization is not “naturally” achieved and identify the different types of synchronization methods that would apply to an application.  You will also learn to determine the best value, most cost-effective method for the application.

Building an Automotive Services Business

Is your business positioned to grow through developing a new market, such as vehicle servicing equipment service, sales & installation?  From a “tech & a truck”, you can grow a complete business segment around automotive lifts, lube systems, and air compressors.  Diversify your offerings and gain economies in your use of resources, from sales to cross-trained techs, to customer service and bookkeeping.  Understand that repairing “garage equipment” can lead to sales and installations worth millions of dollars each year


CFC Industrial Sessions

Pressure Control Types, Uses & Troubleshooting

In this session learn the differences between Direct and Pilot Operated designs as well as the pros and cons of the two designs.  The instructor will go into details on the key items of concern and how to troubleshoot for the following:

  • Relief functions
  • Pressure Reducing/Self Relieving
  • Counterbalance and their pilot ratios
  • Brake and their pilot ratios
  • Sequence
  • Unloading

Three Main Pump Controls & How They Work

In this session learn about standard pressure compensators, load sense, and torque or horsepower limiters.

Common Cylinder Problems & Their Solutions

In this session learn how poor system design causes pressure intensification failures, drifting cylinders, loud banging noise when bottoming out and bent rods.



Instructor: Tony Casassa

Tony started his career out of Purdue University by working at Parker Hannifin in the Hydraulics Group in a combination of sales and engineering positions, involved in complete hydraulic systems for mobile equipment.  He then moved to the OEM side working at Tadano Mantis as their Hydraulic Engineer for the mobile telescoping boom crawler cranes products.  Tony joined Aggressive Hydraulics in 2014 as an Application Engineer and recently moved into a new role as Engineering Manager.



Instructor: Dan Turner

In 1993, after working there for nearly a decade, Dan purchased the ownership of Turner Hydraulics from his parents. In 1996, he started TASCorp (Turner Automation Services Corp), the automation arm of Turner.

In 2016, Dan started GPM Controls to handle the Schrupp Accumulator Program which he had purchased to enter the accumulator manufacturing market.

Dan is a past President and current board member of the Equipment Service Association (ESA). He is an Accredited Instructor for the IFPS and has taught courses for the local community college and trade schools as well as presented at seminars for the PA Dept of Agriculture, ASME, and numerous other groups.


Instructor: Robert (Bob) J. Sheaf, Jr. C.F.P.E.

Bob founded Certified Fluid Consultants (CFC) in 1990 and is owner/CEO of CFC-Solar, Inc (currently operating as CFC Industrial Training). He has been directly involved with fluid power for 45 years and has taught fluid power courses for 39 years throughout the United States, Canada, and Mexico. In 2014, CFC was awarded runner-up as “Best Training and Education” company by 21,000 readers of Penton’s Hydraulic and Pneumatic Publications

He served two years on the Board of Directors for the Equipment Service Association and was a director of the ESA Scholarship Fund.
