Lifting system
The invention provides a lifting system that decreases the amount of energy used while lifting luggage from the ground in a variety of locations. According to the invention, a lifting system operates on a regenerative braking mechanism that provides for recharging the battery of the lifting system using energy created from rotational force generated by the lowering of an arm of the lifting system.
1. A regenerative braking lifting system comprising:
a base configured for mobility, at least one wheel rotatably coupled to the base;
an upstanding post that is operatively connected to the base;
a lifting carriage that is slidably coupled to the upstanding post;
a housing operatively connected to the lifting system, wherein the housing comprises at least one battery, a charger, and a circuitry of the lifting system; and
a motor operatively connected to the housing, wherein rotational force of the motor generates electricity to feed back to the battery.
2. The lifting system according to claim 1 wherein the motor is a three phase induction motor used to drive a worm screw.
3. The lifting system according to claim 1 wherein the lifting system further comprises an AC three phase 24V motor and a geared transmission operatively connected to a worm screw.
4. The lifting system of claim 1 wherein the lifting system further comprises a mechanism that indicates unsafe operations.
5. The mechanism according to claim 4 wherein the unsafe operation is selected from at least one or more of the following: overweight luggage, excessive speed limit of the lifting system, excessive speed limit of the lifting carriage, excessive temperature of the motor, and sticking of the lower limit switch.
6. The lifting system of claim 1 wherein the lifting system further comprises a microprocessor that determines the functionality of the lifting system and communicates with other lifting systems being utilized.
7. A method of operating a lifting system by means of a regenerative braking system comprising:
utilizing a lifting system that includes a base configured for mobility, at least one wheel rotatably coupled to the base, an upstanding post that is operatively connected to the base, a lifting carriage that is slidably coupled to the upstanding post, a housing operatively connected to the lifting system, wherein the housing comprises at least one battery, a charger, and a circuitry of the lifting system, and a motor operatively connected to the housing, wherein rotational force of the motor generates electricity to feed back to the battery;
operating the lifting carriage in an upward direction, wherein the battery drives the motor to move the lifting arm upwardly; and
operating the lifting carriage in a downward direction, wherein the motor rotates by means of mechanical force caused by the weight of a luggage on the lifting arm and wherein a rotational force generates electric feedback to the battery of the lifting system.
8. The method according to claim 7 wherein the lifting system operates in a single mode system.
9. The method according to claim 7 wherein the lifting system operates in a multi mode system.
