STANAG 4101 Towing Attachments

STANAG standards, which are NATO standardization agreements, determine the military standards of NATO member countries. The purpose of the STANAG 4101 standard published within this framework is to standardize the towing attachments for the procurement of new tactical ground vehicles for use by the NATO armed forces.

NATO countries have agreed to adopt certain design features to ensure interoperability of towing attachments (towing hooks, pivot assemblies or other devices) in the procurement of new tactical ground vehicles. This agreement applies to towing eyes on all trailers that must be towed by such vehicles, including weapons and other special equipment.

For the purposes of the STANAG 4101 standard, the term tactical ground vehicle means a military vehicle with special military characteristics, whether designed primarily for military use as adapted from a commercial vehicle, or intended for use in support of combat operations or in direct connection with the training of military units. means.

The general requirements in this standard are determined as follows:

• The towing eyes must comply with the standard annex (Annex A).
• Pulling assemblies (axis assembly or hook, pin and jaw) must be sized to accept a 76,2 mm x 41,2 mm towing eye.
• The design of traction ropes and small assemblies should ensure the maximum possible articulation of the link.
• Longitudinal springing should be included in the towing eye if required for any type of trailer. The traction device does not need to be sprung.
• To ensure full NATO interoperability, equipment must be provided to enable rotation of the pivot assemblies and towlines must be secured to prevent rotation.
• Axis assemblies or tow hooks on tactical land vehicles must be positioned using the hitch axis and heights specified in the ISO 11406 standard as a guideline to ensure horizontal articulation of the truck/trailer unit.
• Materials must be acceptable to national approval authorities.

Application of the requirements under this standard to the procurement of new tactical ground vehicles is dependent on the delivery of the necessary instructions.
