Vertical Package Conveyor

Problem: These complex, continuously moving "dumbwaiters" are inherently dangerous to personnel and maintenance intensive. So many safety cutouts and devices have been added over the years that it is virtually impossible to troubleshoot.

Solution: MTTC, with NSWC/CD/ Philadelphia will develop and test a computer based control system that will permit much more efficient safety interlocks, automatic lubrication and predictive maintenance.

Benefits

Estimated Navy Cost Avoidance:

Minimum annual:      $2,100 K

Minimum 15 Year:  $31,500 K

Fleet Impact: During the past 10 years, there have been several sailor deaths and serious injuries from these elevators. A computer based logic system will prevent accidents and eliminate the need to perform some dangerous maintenance actions.

Status: Ongoing

All shore-based testing has been completed at the NSWC/Philadelphia land-based test site. Prototype systems have been installed on USS CARL VINSON (CVN-70) and USS THEODORE ROOSEVELT (CVN-71). Feedback to date has been very positive.

Application
• All Surface Ships (200+ of various classes and types). Multiple systems per ship.
