Mobile industrial rack system
A mobile industrial rack system which includes a flue spacer, a carriage spacer, and a synchronous motor control that individually and collectively allows the rack system to be used on unleveled surfaces. The industrial rack system is therefore well suited for storage facilities in which it is not possible or not desired to level an otherwise unleveled floor.
1. A mobile rack system comprising:
a first rack mounted for movement on a floor;
a second rack mounted for movement on the floor;
a mobile carriage having wheel structure engaging the floor and supporting the first rack and the second rack for rolling movement on and along the floor; and
a flue spacer having interfitting members adjustably interconnecting the first rack and the second rack, and enabling the first rack and the second rack to move relative to another when the wheel structure of the mobile carriage moves on and along portions of the floor that are not level, wherein the flue spacer includes a first mounting member coupled to the first rack, a second mounting member coupled to the second rack, a first extension connected to the first mounting member, and a second extension connected to the second mounting member, wherein the first extension is interfitting in the second extension in a manner that allows the first extension to slide along a first axis within the second extension.
2. The mobile rack system of claim 1 wherein the flue spacer is further adapted to allow relative movement of the first and the second racks in at least two directions.
3. The mobile rack system of claim 2 wherein the at least two directions includes a lateral direction and a vertical direction.
4. The mobile rack system of claim 1 wherein the second extension partially shrouds the first extension in a manner that allows the second extension to move along a second axis transverse to the first axis.
5. The mobile rack system of claim 4 wherein the first extension has a laterally extending slot and the second extension has a vertically extending slot aligned with the laterally extending slot, and the flue spacer further includes a pin extending through both the laterally extending slot and the vertically extending slot along an axis that is transverse to the first and the second extensions.
6. The mobile rack system of claim 1 further comprising a rail mounted to the floor, wherein the mobile carriage includes a pair of wheels adapted to ride along the rail.
7. The mobile rack system of claim 6 wherein each wheel has a tread pattern and a contour matched to that of the rail.
8. The mobile rack system of claim 7 wherein the tread pattern includes a pair of flanges spaced to form a channel therebetween.
9. The mobile rack system of claim 6 further comprising a motor that drives at least one of the wheels and a motor controller that controls operation of the motor.
10. The mobile industrial rack system of claim 9 further comprising a synchronous motor control and wherein the motor controller provides feedback regarding operation of the motor to the synchronous motor control which in turn controls the motor controller based on the feedback.
11. A mobile rack system comprising:
a rail mounted directly to a floor;
a first rack adapted to support a load;
a second rack adapted to support a load;
a flue spacer having interfitting members adjustably interconnecting the first rack and the second rack; and
a first mobile carriage rollably supporting the first rack along the rail, and a second mobile carriage rollably supporting the second rack along the rail; and
a carriage spacer movably interconnecting the first mobile carriage and the second mobile carriage in a manner that allows the carriages to move independently of one another when the racks are translated along the rail.
12. The mobile rack system of claim 11 wherein the rail is further adapted to be surface mounted directly on the floor.
13. The mobile rack system of claim 11 wherein the carriage spacer is further adapted to allow the first and second mobile carriages to move independently of one another when the racks are translated along the rail over portions of the floor that are not level, and includes a pivot pin against which the carriages move relative to another when the carriages move along the rail.
14. The mobile rack system of claim 11 wherein the flue spacer allows the first rack and the second rack to move independently of one another.
15. The mobile rack system of claim 14 wherein the flue spacer allows the first rack and the second rack to move relative to another along a first axis parallel to the rail and a second axis transverse to the first axis.
