Time consuming repairs? Try a permanent fix to lug wear!

For many workshops, machine owners and operators, lug wear is simply accepted as an unavoidable fact of life that requires repeating maintenance. But does it need to be?

Do you find it challenging to measure the wear of the lug?

It can be challenging to measure lug wear accurately. 

We have the perfect solution - order an extra pair of sleeves! 

Unsure if you got the lug wear measurement correct before dismounting the original straight pin? We offer repair kits that give a total expansion possibility of 4 mm! 

The Expander System should be part of the bridge standard. The system introduces an entirely new way of thinking; a solution that makes operation safer, maintenance work easier and saves a lot of money!
