In the past few months, we have had some customers who own older Eagle Lifts (at least 10 years old) order new Rub Blocks for their lifts. Most lift operators are unsure exactly what a rub block is, why we use them in our lifts an how they are replaced.
Rub blocks are an important part of each lift and have a major role in making sure the lift performs the way it should. Eagle uses a nylon rub block for each of our 2-post and 4-post lifts. Rub blocks are installed on the carriages of the 2-post car lift, at the top and bottom of each carriage – 8 total per side. On the 4-post lift, a 10”x 3” rub block, 2 per post (8 for each lift) are bolted on to the end of each cross member on the four corners of each carriage, top and bottom.
Once installed, the rub blocks become a stabilizer for the lift while going up and down. These rub blocks are the bridge between the actual lift post and carriage, or cross member. The rub blocks are designed to secure the carriage or cross member inside each lift post and not allow any movement during use. The nylon creates a steady and smooth lift. We recommend a lubricant in each post to reduce the friction of block, and help with the travel of each lift. Continue reading RUB BLOCKS ON YOUR CAR LIFT: 2-Post and 4-Post lifts
