Patent attributes
A power rack apparatus is provided for spotting weights. The power rack apparatus allows a user to lift weights to failure without the need of a human spotter. The power rack apparatus includes a power rack frame, a weight-catching system, and a controller. The power rack frame is a standard structural frame of a power rack that allows a user to rack weights after he or she has completed a weightlifting workout. The weight-catching system spots weights for the user using at least one chain drive mechanism, a first racking arm, and a second racking arm. Through the weight-catching system, the user is allowed to lift weights to failure and is spotted by weight-catching system when necessary. The controller manages and controls the weight-catching system in order for the weight-catching system to effectively spot weights for the user.
