A lifting mechanism includes a load bearing structure, and a carrier. The carrier is configured for supporting a load. The carrier is moveable relative to the load bearing structure in a substantially vertical direction relative to a ground surface, along a vertical axis. A load carrying spring applies a spring force that biases the carrier relative to the load bearing structure in a direction along the vertical axis. A negative stiffness device interconnects the carrier and the load bearing structure. The negative stiffness device applies a device force that biases the carrier relative to the load bearing structure in a direction along the vertical axis. The device force opposes the spring force. The device force includes a magnitude that is substantially equal to the spring force in any of a plurality of different positions of the carrier relative to the load bearing structure along the vertical axis.
