It’s a heavy rope. Unless you’re pulling steady with another truck, you won’t take up full slack. The men only apply momentary tension on the rope and then reset but they have to do it fast enough to keep the trucks momentum going. My guess is they’re pulling 400-500lbs in spurts.
these pulls are nothing. . louis cyr would PUSH UP an incline , an empty train freight car. that’s 60,000lbs. UP so all that dead weight was pushing back.
