What should you check regarding the safety chains when coupling a converter dolly?
a.That they are loosely attached for flexibility
b.That they are secured and crossed under the coupling
c.That they are removed before driving
d.That only one chain is attached
Explanation
Safety chains must be securely attached and crossed under the coupling to prevent the dolly tongue from dropping to the ground if the pintle hook connection fails. Crossing the chains creates a cradle to catch the dolly tongue.
