Pintle Hooks When used in a commercial or defence department application, often a 75mm ring type towing eye is requested for the offroad coupling. This style of coupling is similar in function to ball type couplings (fixed and override) but instead of the connection to the tow vehicle being a standard 50mm ball, the connection is a 75mm inside diameter ring and this attaches to a pintle hook fitted to the tow vehicle. These types of couplings are typically used in applications where the tow vehicle is a heavy commercial truck. 50mm towballs typicaly have a maximum capacity of 3500 kg ATM (total loaded mass), ring couplings are used when higher loads are involved Description 6 tonne Pintle Hook receiver Specifications Capacity: 6000 kg Mounting Pattern: 45mm x 85mm Hole Diameter: 12.5mm
