The Drawbar is intended for mobile use in an area that is protected from the weather.
• The area should be free from mould and fungus and show no traces of rodents or other pests
• Do not install or use in close proximity to industrial plants that produce chemical emissions.
• Resistant to many of the substances usually encountered in the production area, such as water, mineral oil, grease and detergents. In case of doubt regarding
resistance to certain chemicals such as test oil, alloyed oils, aggressive cleaning substances, solvents or brake fluid, we advise that you consult your specialist
item representative.
• Avoid long periods of contact with highly acidic or alkaline substances.
• Consult the manufacturer if using in very salty air.
• The Drawbars are fundamentally suitable for use in dry, vibration-free environments where temperatures range from -20 °C to +70 °C.
If they are to be used for applications outside these limits, item GmbH must be consulted.
3. Operating data
Diagram for determining the maximum trailer load on the first Drawbar Coupling of the tugger train in relation to the acceleration/braking deceler-
ation and maximum travel speed. The ratio of travel speed to acceleration/braking deceleration is determined to DIN 15172, under the condition
that the numeric value of braking distance s [m] corresponds to a third of speed v [km/h] of the tractor train.
