Most Advanced Manufacturing Facility In The World

Judging by the “Tesla Motors” video published by Wired, the Tesla Factory appears to be the cleanest, most cutting-edge auto manufacturing facility to date.

WHAT IS THE NUMMI PLANT?

NUMMI (New United Motor Manufacturing, Inc.) was an automobile manufacturing company jointly owned by General Motors and Toyota from 1984 until 2010. The size of the NUMMI plant stretches out to 5.3 million of square footage and with the latest buzz of the Tesla Factory’s expansion, it is looking to double that size to accommodate 14,000 workers and make room for activities.

APPLICABLE MATHEMATICS

Let's put the size of the Tesla Factory to scale. A regulation-sized NFL football field is 360 feet long and 160 feet wide. Using the Length x Width rule: 360 (Length) x 160 (Width) = 57,600 square feet. If you take 5,300,000 square feet and divide it by 57,600, the size of the Tesla Factory is equivalent to 92 football fields. As shown in the “Tesla Motors” video by Wired, there is working evidence that caster wheels are used to help transport heavy items within the 5.3 million square foot space. This post will go over some of the ways that casters are used within an advanced automotive plant.

1. MANUFACTURING CLEANLINESS

Cleanliness and safety go hand-in-hand. As seen in the photo above, black markings are placed on the floor to indicate the tool cart’s proper location when not in use. The tool cart is kept at arm’s length when needed, and with the help of caster wheels, the tool cart can easily maneuver around a factory worker’s workflow.

2. PULLING THE WEIGHT

To anyone not familiar with a tugger and cart system, a tugger is a cart for material handling in which the average tugger can handle a total weight load of 10,000 pounds. To help transport the frame of a Tesla car on over to the next stage of assembly, the tugger will require the proper caster wheel to ALSO handle to the tugger cart’s carrying capacity.

Referencing our “Selecting The Right Caster” page - the gross weight of truck/dolly/[cart] should be divided by the number of casters/wheels on which weight is distributed. There is the possibility that all 4 caster wheels will not have complete contact to the floor on a 4-caster/cart setup, therefore the carrying weight of the cart should be divided by 3 to ensure that your caster wheels can provide more than enough support.

For instance, if you were to take a 15,000-pound cart and divide it by 3, each caster you intend to install onto the cart should support a weight load of 5,000 pounds per caster. Doing so will create a safety allowance of 33% that will keep your employees safe and will protect the product that is being transported.

3. DROP OFF AND PICK UP

Using a tugger cart to transport the frame of the Tesla S from one stage of assembly onto the next stage can help a worker from overexerting their bodies from pulling the frame themselves.

4. LIGHT UP THE DETAILS

After being fully assembled, a thorough run-through of the car is necessary to confirm that it is spotless. Nothing’s better than having a mobile lighting system that a worker can configure based on their needs.

5. PUSH IT TO THE LIMIT

Tuggers are not going to set up the carts without the assistance of human labor. As far as we know, machines do not feel pain the same way humans do. So, if a 90 to 300-pound worker has to push or pull a 10,000-pound cart manually, be sure that the casters are capable of lowering push/pull resistance to prevent injuries.

CONCLUSION

Tesla is currently working with a manufacturing space equaled to 92 football fields. At the time of this writing, Tesla is working with new plans of expanding the 5.3 million square feet of space into 10.6 million square feet to accommodate 14,000 workers and more activities.

10.6 million square feet divided by 14,000 employees will amount to 757 square feet of working space per employee. 750 square feet is about the size of a modest two bedroom, one bathroom apartment. If an employee has to maneuver heavy duty product around a 750 square foot space - all day, every day - a reliable cart with dependable casters should be installed to help take the load off.
