Abstract
A spa cover lifting device employs a pivot bar attached to a piston and transverse bar. The pivot bar and piston are anchored adjacent to a spa, and the transverse bar extends in a perpendicular direction across the spa cover. The pivot bar is anchored to the spa by a first mounting bracket, and the piston is anchored to the spa by a separate, second mounting bracket. As the pivot bar is raised, it is augmented by the piston to assist in lifting the spa cover, while the transverse bar transfers the lifting force to the spa cover.
