Tronair manufactures a full line of quality, OEM approved tripod and axle jacks. The threaded rams of all 5 thru 30-ton tripod jacks are equipped with handwheel safety nuts.  Aircraft stabilizer stands help to ensure the safety of your crew as well as your aircraft when lifting and shoring with an aircraft jack. Some tail stands are even equipped with an alarm that warns you when the weight on the load cell exceeds 100 pounds. This helps to ensure safety during maintenance, lifting, and shoring.
