Why must the converter dolly be positioned carefully and its drawbar handled with caution when coupling doubles?
- A.Dollies are light enough to carry by one person
- B.The drawbar has no weight because the dolly is balanced
- C.A dolly is heavy, can roll or drop, and a falling drawbar can seriously injure the driver; it should be moved with the tractor or by hand only over short, controlled distances
- D.Dolly position does not affect coupling the rear trailer
Correct answer
C. A dolly is heavy, can roll or drop, and a falling drawbar can seriously injure the driver; it should be moved with the tractor or by hand only over short, controlled distances
Why
Drivers are hurt every year by dolly drawbars that drop or dollies that roll unexpectedly. Treating the dolly as the heavy piece of equipment it is, and never standing where a falling drawbar can strike, is basic practice.
