Our client is a leading supplier of U.S. Military defense equipment. This order was part of a government contract for manufacturing high technology heavy defense components. Firstly, BlastOne developed high-technology blast and paint booths for surface preparation and coating for defense-related components. Subsequently, BlastOne designed and supplied a materials handling solution. The solution should move parts up to 50 feet in length but also weigh up to 80 tons.
Upon successful completion of blast and spray booths project, Blast One was approached to help integrate the logistic solution for their large products in the enclosed booths. Overhead cranes were not an option for our client, so a floor-lift system would be required. Blast One integrated a solution that included a tandem, cart-carriage system to provide a safe and accessible solution.
Other design considerations:
The parts have portions at either such that the center of gravity is offset
Batteries must have capacity to drive a fully loaded cart (56 tons) a minimum of 2,000 feet on a single charge at a mid-battery life of 500 charge / discharge cycles
Drive system must power all wheels
Pendant controls to include wireless, and backup wired controllers
Different drive modes to include
- Turntable: ability to turn 360 degrees in a circle, clockwise or counter-clockwise
- Standard Turn Radius: Ability to make sharp turns in an out of the booth
- Crabwalk Mode: Ability to make sideways or angular movement
Early conceptual design of the solution:
Final conceptual design:
Loaded to 224,000 lb during Site Acceptance Test:
BlastOne’s client now has a safe and effective method of transporting their large products in an out of the booths, as well as many other parts of the plant. Having two of the units that can each operate totally independent of each other will provide options for moving heavy equipment throughout the facility.
“Based on our recent project, I would recommend BlastOne as a reputable company to do business with. The project was handled professionally, communication was sufficient, follow up was good when needed. Attention to detail was good as well, and the BlastOne Project Manager was a good representative for BlastOne, and pleasant to conduct business with.” – Facilities Engineer
