About the Trailer Jack Stand

The trailer jack stand is a steel piece of material handling equipment that helps support the front end of a semi trailer during loading and unloading when no tractor is coupled to the trailer, according to beacontechnology.com. The Occupational Safety & Health Administration (OSHA)'s stance on trailer jacks is "fixed jacks may be necessary to support a semi trailer and prevent upending during the loading or unloading when the trailer is not coupled to a tractor." Economy trailer jack stands are available with or without wheels. This jack stand has a static capacity of 50,000 pounds and a lifting capacity of 5,000 pounds. It has a spin top for height adjustment and can weigh 45 to 60 pounds.
