Laboratory Testing

Meeting the quality requirements of today’s tree stand and fall harness industry

Our laboratory offers modern equipment and data acquisition for tree stand and fall arrest harnesses. We can test the materials used in making tree stands or fall harnesses and perform all the necessary testing on the assembled systems.

Before testing begins, our engineers and scientists work with you to identify your specific needs, develop material evaluation and testing programs to fulfill those needs, and then translate the results into meaningful action. This includes identifying the relationship between material conditions, test results and what they mean to overall performance. We will work hard to provide a quick turnaround and guarantee you quality service on all your testing needs.

Our laboratory provides complete structural engineering support

Including support for the design, analysis, inspection and evaluation of structural systems. Quality planning and technical ability allow our structural engineers to provide practical and efficient solutions for our clients. Our staff has the expertise in structural design and structural repairs to help solve your problems. Our engineers and laboratory personnel can also provide expert witness and litigation support.

Our structural engineers have extensive experience with a variety of structural systems including structural steel. TEC Services’ engineers have performed shear, tensile, deflection and fatigue testing on all types of stands. Our engineers are licensed to perform engineering services in Pennsylvania, Mississippi, Tennessee, North Carolina, South Carolina, Georgia, Alabama, and Florida.

SGS TEC Services tree stand testing laboratory was recently setup with state of the art data acquisition for fall harness, fatigue testing (repetitive loading) and static load testing. The fall harness will be tested using a data acquisition system capable of over 4,000 readings per second. TEC Services has the ability to test deflection during loading using Linear Differential Variable Transformers (LDVT) automated data acquisition or manual readings, in accordance with the preference of the manufacture. Fatigue testing is performed using an automated rotating cam system.
