Abstract: A hydraulic lift for a truck trailer, having a pair of hydraulic cylinders mounted to the under side of a semi-trailer. The bottom of the cylinder pistons are connected to a foot, which sits on the ground. A telescoping jackstand positioned between the two cylinders, and can be locked into its extended position with a locking pin. The jackstand acts as a safety device in case the hydraulic system looses pressure, and also acts to take the load off of the hydraulic cylinders when the trailer needs to sit for extended periods of time.
