Dowel Pin Lifting Lug And Connecting Piece Section Drawing Detail

This AutoCAD drawing presents detailed section views of dowel pins, lifting lugs, and connecting pieces used in mechanical and equipment assemblies. The drawing clearly illustrates dowel pin arrangements with tight fit tolerances, including 16 mm diameter pins positioned at 0 degrees and 172.5 degrees locations, along with precise PCD references of 1490 mm and 1505 mm. Section views show accurate seating of pins within mating components, ensuring alignment and load transfer accuracy. Connecting piece details include a 430 mm long stud with 1 by 2 inch BUN threading, 25 mm thick plate section, and defined radius profiles such as R630 mm and R716.5 mm for curvature control.

The drawing further details lifting lug geometry with 30 mm and 32 mm thick plates, 25 mm hole diameter, chamfers of 15 by 45 degrees, and overall lug height of 100 mm. Long weld details are shown with 60 degree groove angles, 1.5 mm root gap, and chip back and weld notes for fabrication clarity. Tie rod and spacer connection details include multi-stage weld sequencing and support plate alignment.
