WITS Metal Fabrication’s Post

Today’s Project: Secondary Stacker Hoist. Our team did a great job fabricating and assembling this unit. One issue that came up, which wouldn’t be an issue in other circumstances, was the HSS supplied to us had the weld seam in the wrong location causing the lengths to be deformed by 1/8” which is out of tolerance for the hoist knee. Our local supplier was great and found some material in their yard that was to spec and happily replaced it for us. This project required precision machining and fabrication to ensure all the components installed work properly. We must ensure that the shaft is level, and the knee roller is at the same position at all knee locations before installing the lower cam follower. Then we can install knees and knee connector bar followed by upper cam followers, shear arm and shear bolt. Adjust the upper and lower eccentric cam followers to level the knee ensuring the knees can move back and forth smoothly. Adjust the hear arm eccentric cam follower to remove clearance to knee and install bearing keepers, then it is ready to operate!   #forestryequipment #sawmill #welder #steelfabrication #metalfabrication #machineshop

Excellent work WITS team!
