Abstract
A vehicle lift utilizes a locally stored energy source configured to deliver energy at a high rate to a DC motor to provide a fast rise time and to replenish that energy at a lower rate over a relatively longer period of time.
Claims34
A vehicle service system having an associated external electrical power source, said vehicle service system comprising:
- a plurality of spaced apart service bays disposed at predetermined locations, each service bay comprising:
- a. a respective vehicle lift, each respective vehicle lift configured to lift a respective vehicle, the respective lift comprising
- i. at least one moveable member configured to engage a vehicle;
- and
- ii. an electric motor operable to cause said at least one moveable member to raise;
- b. a locally stored electrical energy source configured to deliver energy to said electric motor sufficient to cause said electric motor to raise said at least one moveable member through at least one lift cycle;
- and
- c. means for maintaining the locally stored electrical energy source at a desired energy level, said means comprising a charging circuit connected to said locally stored electrical energy source
- wherein all of the respective charging circuits are simultaneously connected to and drawing current from said external electrical power source during raising of the respective at least one moveable members.

A vehicle lift comprising:
- a. at least one moveable member configured to engage a vehicle;
- b. an electric motor operable to cause said at least one moveable member to raise;
- c. a locally stored electrical energy source configured to deliver energy to said electric motor sufficient to cause said electric motor to raise said at least one moveable member through at least one lift cycle;
- d. means to maintain the locally stored electrical energy source at a desired energy level, said means comprising a charging circuit connected to said locally stored electrical energy source, said charging circuit connected to and drawing electrical power from an external electrical power source, said charging circuit configured to restore the equivalent of one lift of energy to said locally stored electrical energy source within a period of time that is no greater than twenty minutes while drawing electrical power from said external electrical power source during said period of time at no greater than three amps.

A service bay comprising a vehicle lift, said vehicle lift comprising:
- a. a frame permanently mounted in place in the service bay;
- b. at least one moveable member carried by said frame, said at least one moveable member configured to engage a vehicle;
- c. an electric motor operable to cause said at least one moveable member to raise;
- d. a locally stored electrical energy source carried by said frame and configured to deliver energy to said electric motor sufficient to cause said electric motor to raise said at least one moveable member through at least one lift cycle;
- e. means to maintain the locally stored electrical energy source at a desired energy level, said means comprising a charging circuit connected to said locally stored electrical energy source, said charging circuit connected to and drawing electrical power from an external electrical power source.
