Both 3 dimensional (xxx formats) and 2D CAD files are available for those interested in the Dorris product line. Because of the vast configurability of the TR/TL product line, we ask that for 3D files please send a message to us at our contact page https://www.dorrisco.com/contactus.aspx, include the model you are interested in, the desired drive configuration, and the 3D CAD format desired. For example: 307TL gearbox with 3” drive shaft and CEMA adaptor in an IGS configuration. Some of these data files may be too big for standard e-mail support, so in those situations, you will be given an invite to a web-storage page where you can download the files. The 2D drawings are offered in the versatile .DXF format with many levels that allow a user to select among the various gearbox model options. Included are most of the models for the TR and TRC series shaft mounted drives, TL and TLC series screw conveyor drives, C-faces TR series drives, and the Base type gear drives. These CAD drawings may be used in whole or in part, as stand-alone drawings or as individual parts in other drawings and/or assemblies. Most representations are taken from our actual computer drawings that we use for manufacture. These drawings are the property of the Dorris Company. They are offered upon the condition that they shall not be copied, reproduced in any manner, or submitted to others without our written consent (except as noted within these instructions) or used in any way detrimental to the interest of this company, and shall be returned upon demand.
