The next generation CDK Air Force Dolly Set was selected by the Air
Force Material Command (Air Force Life Cycle Management Center)
in 2018 and was subsequently tested, certified and fielded to more
than a dozen U.S. Air Force bases on three continents. CDK’s new
system was fielded across the Air Force to assist with shelter handling,
transport and aircraft loading for numerous applications with the
following end users:
- Air Support Squadrons
- Vehicle Readiness Squadrons
- Combat Search & Rescue Wings
- JSTARS Air Control Wings
- Electronic Warfare Training Squadrons
- Communications Squadrons
- Material Maintenance Squadrons
- Space Based Surveillance Squadrons
- Fighter Wing Squadrons
- Airlift Wing Logistics Squadrons
Quad-Con Transport
Road & Rough Terrain Certified
The CDK next generation system was selected based on its long military lineage and
reputation for unmatched fielded capabilities including the following:
- Diesel Engines for true self-containment (no electric batteries that need recharging in
the field). Dolly Set batteries recharge from the diesel engines. - Side Lifting Capabilities for cross loading in the field (truck,
trailer, rail) - 12,000 miles prior testing and certification at Aberdeen
Proving Ground - Unique 3-wheel handling mode for ease of unloaded
handling and hydraulic powered connection to shelter - Self-leveling axle feature to level shelters on uneven terrain
- Commonalty with US Army Standard M1022-A1 (Training,
Logistics) - U.S. Air Force Internal Air Transport Certification
