21 Administrative and Technical Information 1. Guidance, services and offers Please contact your local ROTA representative listed in our representatives list on the back of the catalogue if you have any questions or concerns. We require a full list of technical specifications including any available sketches and data sheets for the preparation of an appropriate offer. This information makes it possible for us to determine whether a standard or custom element is the most cost-effective solution for you. For complex applications, our representative or the home office will send you a questionnaire about the exact specifications for what you need. Terms and conditions for payments and deliveries are included with our offer or available on our website at Company General Terms. 2. Orders and deliveries Please include the offer number on your order along with the exact quantity, product name and number. Please send your order to your local ROTA representative. 3. Availability Most of the standard products listed in our catalogue are available from stock through your local representative or directly from ROTA AG. Custom pieces for a specific customer requirement are produced and delivered as specified in your order confirmation. The delivery time for special custom pieces can be reduced by signing a call order agreement (make-and-hold-order) with ROTA AG. Please contact us if you would like to discuss this. 4. Technical information Please observe the capacity limits for our elements as specified in the catalogue. If you are in doubt, please contact us or your ROTA representative. Please follow the assembly instructions detailed in the catalogue. Make sure that your assembly workers are instructed correctly. If you have any questions, please contact us or your ROTA representative. Assembling elements: To attach our elements or mounts, please always use the largest dimensioned standard machine bolts possible with a minimum strength class of 8.8 that fit into the drilled holes in the elements or attachment clamps. Use an IO 898 table or your screw supplier s guidelines for the maximum tightening torque. If in doubt, control your bolt attachments using the VI Guidelines Use IN 125A stamped washers to attach housings with unworked drilled holes in the casting (for example A 50) or oblong holes (for example M supports). 5. Proviso This catalogue and our other technical information are intended solely for your orientation and information; they may not be construed as absolutely binding in any way. We ask that you adapt the assembly and use of our products in a way suited to the prevailing conditions and situation. The reproduction of this document in full or in part may only be done with our expressed written permission.
