Proof Load Testing of Industrial Equipment - Clark Testing

Proof Load Testing of Industrial Equipment

Clark Testing has a long history of proof load and structural fatigue testing of industrial equipment, including material handling and lifting equipment. Clark’s mechanical laboratory has provided testing, product validation and certification of components including cranes, hoists, cables, slings, forklifts, telehandlers, aerial lifts, scissor lifts and scaffolding.

Clark’s structures laboratory conducts proof load testing on industrial equipment to ensure safety and compliance with regulatory standards. The functional nature of this equipment can sometimes overshadow the critical ANSI and OSHA standards that regulate the safety requirements of this equipment.

With one of the largest structures laboratories in the United States, Clark’s team can apply static or dynamic loads up to 1.5 million lbs. in the vertical or horizontal axis. Clark Testing is fully accredited to ISO 17025-2017 by the independent accreditation agency A2LA.

Forklift & Telehandler Equipment Testing

Clark Testing’s mechanical lab in Buchanan, Michigan was formerly known as Clark Engineering Services and has a long history of testing forktrucks and qualifying material handling equipment. Clark provides product validation & certification services for forktrucks and telehandler equipment with services such as: structural, load, fatigue, dynamometer, tilt/tip, ROPS/FOPS, torsional fatigue and functional or cyclical aging.

Scaffolding, Shoring and Anchoring System Testing

Clark Testing provides load testing of scaffolding, shoring, and anchoring devices per customer specified standards or industry standards including: ANSI A10.8, CAN/CSA S269.2, ANSI/SSFI SC100-5, and OSHA 1926.451. Clark’s proof load testing capabilities allows our test engineering team to replicate load, motion, pitch, wind, torsional fatigue and any other variables introduced in the work area. Clark’s engineers and test technicians can develop a test program to simulate load profiles and field environments.
