Tronair's tripod jacks meet or exceed all known commercial and military requirements and specifications, and are cycle tested, load tested and proof-load tested to ensure the jack's hydraulic and structural integrity. The automatic safety by-pass valve prevents the lifting of a load greater than the capacity of the jack. Threaded rams with mechanical lock nuts prevent lowering of the jack under load in case of hydraulic leakage. They are designed and built to withstand harsh environmental conditions, rugged use and to provide many years of continuous service.
