How should the pintle hook be checked after coupling a dolly or trailer by its drawbar eye?
- A.The eye should be seated in the hook, the latch should be closed and locked over it, and safety chains should be properly attached
- B.If the eye rests on top of the hook, the weight will seat it later
- C.The latch is optional when safety chains are used
- D.Chains alone are an acceptable coupling if the hook is damaged
Correct answer
A. The eye should be seated in the hook, the latch should be closed and locked over it, and safety chains should be properly attached
Why
A pintle coupling is only complete when the latch locks the eye in the hook; resting contact is not a coupling. Chains are the backup if the main coupling fails, never a substitute for it.
