Abstract
A lift system for raising and lowering a carriage may comprise a pin-in-track position indexing apparatus having a position indexing track with first and second inclined branches and at least one guide pin for engaging the position indexing track. The guide pin may be attached to the carriage. Switching apparatus associated with the pin-in-track position indexing apparatus allows the guide pin to follow the first and second inclined branches of the position indexing track. An actuator operatively associated with the pin-in-track position indexing apparatus actuates the pin-in-track position indexing apparatus to raise and lower the carriage.
