PROBLEM
Cargo aboard naval vessels is typically secured with manual tie-down devices. These devices are slow and inefficient, and tend to break unexpectedly; often damaging cargo.

The Office of Naval Research asked PCDworks to create a self-powered, remote-controlled tensioning system that would reduce damage to cargo, increase load and unload times, and minimize crew involvement.

PROCESS
PCDworks created a system of individual units which, when networked together, provide the ability to simultaneously secure and release loads. In this effort, PCDworks designed customized multi-hop wireless communications, advanced sensing capabilities, and a proprietary self-releasing hook. Additionally, the system included a custom motor, high performance battery pack, linear actuator, printed circuit boards, and carbon fiber case.

RESULT
A lightweight system that is strong, yet reliable. Our new semi-automated system requires minimal human involvement to tension and release loads, reducing load and unload times by 20-percent. Additional uses are being considered for nuclear waste transport, rail shipping, and aircraft docking.
