• Keep the angle of the towing rope as small as possible. Keep the angle between the center lines of the 2
machines to within 30 °.
• Usually, use a towing machine of the same class as the machine being towed. Check that both towing ma-
chine and towed machine have ample braking power, and rim pull to allow them to control both machines
on slopes or on the tow road.
• When towing a machine downhill, it may be necessary to connect another machine to the rear of the towed
machine in order to provide ample rim pull and breaking power. The controllability of the machines can be
secured by this method.
• Towing may be performed under various conditions, so it is impossible to determine beforehand the re-
quired traction force. Towing on flat level roads will require the minimum rim pull, while towing on slopes or
on uneven road surfaces will require the maximum rim pull.
• Connect a wire rope to the part indicated with the arrow in the drawing.
For the towing pin, see “METHOD OF USING TOWING
PIN (3-119)”.
