Keyfeatures
Cradle Integration – Pin or 90" rail systems secure EC cradles for repeatable coupling.
COBRA Interface – Forklift tubes and defined pockets enable COBRA engine changes and safe handling.
Multi-Axle Steering – Pneumatic tires and a steerable axle improve tracking and maneuverability in tight spaces.
Tow-Ready Design – Tow-bar and standard tow eye interface common tugs for controlled moves.
Fleet Labeling & Compliance – Aircraft labels and supplied documentation support correct application and conformity.

Engine-specific labeling supports accurate cradle pairing and operator checks.
Operator and maintenance manuals with spares lists guide correct use and servicing.
Fixing brake stabilizes the dolly during rigging and positioning tasks.
Bootstrapping is supported when paired with designated EC cradles and adapters.
Mobility & Transport
Two axles with pneumatic tires distribute loads for smooth towing in hangars and on ramps.
Forklift pockets permit loaded or unloaded moves and COBRA setups.
Standard tow-bar and a steerable axle enable precise positioning in confined spaces.
Durability & Corrosion Protection
Rigid welded steel frames deliver long service life under repeated handling.
Skydrol-resistant paint protects surfaces in maintenance environments.
Standard yellow RAL 1028 finish enhances visibility on specified models.
Why RH Aero?
Modular Bases—COBRA Ready
ED dollies standardize how mixed fleets are handled by unifying coupling methods, forklift interfaces, and towing geometry. With documented procedures, pin/rail options, and fluid-resistant finishes, crews execute predictable engine moves while protecting assets. Integration with COBRA and EC cradles reduces reconfiguration time and keeps operations moving.
