Abstract
Disclosed is a counterbalance system for moving a payload and a method for counterbalancing the payload. The system and method comprise a resilient member that is in communication with the payload to be moved and two resilient members that are in communication with either end of the first resilient member. An actuator is in communication with the first and third resilient members and a payload arm, attached to the payload, is in communication with the first and second resilient members. The resilient members may be compressed and relaxed during movement of the actuator and the payload arm so that energy may be transferred between the system and the payload to counterbalance the weight of the payload.
