Abstract
A patient support apparatus supports a patient and includes a litter. A base is disposed below the litter. A lift mechanism is configured to move the litter and the base relative to one another between extended and collapsed positions. The lift mechanism includes first and second frame assemblies each including an outer frame member and an inner frame member arranged to move within the outer frame member. First and second rollers and first and second slide members are disposed between the outer and inner frame members. The first and second rollers are arranged to roll along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the litter. The first and second slide members are arranged to slide along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the base.
