The Omega Undercarriage

When L&H designed, engineered, and manufactured the first Omega undercarriage, our goal was to provide our customers with an assembly that would perform better and last significantly longer than industry standards, dramatically decreasing machine downtime, as well as the total cost of ownership of their system. Now, with undercarriages operating across the globe, L&H has proven that the Omega system lasts 30% longer than industry standard systems, every time.
