Couplers (continued)
Tronair recommends a telecoupler pintle hook arrangement. This arrangement is known to eliminate binding. Tronair offers a
Standard Telecoupler, Model Number 01-1950-5000, for use on tugs.
Reference Figure 4 .
Damage to the towbar and/or aircraft can result by towing or pushing an aircraft with an incorrect size eyebolt or pintle pin. A
correct size eyebolt will make contact with the pintle pin. A gap between the eyebolt outside diameter and the coupler face
plate should be easily seen. An eyebolt which is too large will cause the eyebolt to make contact with the face plate of the
coupler. When the eyebolt is too large for the coupler, a gap between the inside diameter of the eyebolt and the coupler face
plate will be seen.
Reference Figure 5 .
To ensure proper towing and pushing, check to make sure the pintle pin diameter is not too long for the eyebolt's inside
diameter. An approximate one-half inch (1/2") gap between the pin diameter and the eyebolt should be seen. If any of these
conditions are not met, please contact Tronair for information to obtain a new coupler.
