A platform system includes swing arms for moving the platform from a lowered position to a raised position. In one embodiment, a pair of swing arms and a pair of telescoping vertical members are mounted to opposing frame members. The swing arms are capable of moving from a canted position to a vertical position, which extends the telescoping vertical members and raises the platform to the raised position. The swing arms are connected to a drive mechanism that moves the swing arms from the canted position to the vertical position. The drive mechanism may include a gear box, and a pair of lead screws connected to the gear box. The lead screws may extend from opposing sides of the same gear box, with the gear box configured to rotate the differently handed lead screws.
