Upgrade our current undercarriage technology to continue to perform better and last longer than industry standards.
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 their machine downtime, as well as the total cost of ownership of their shovels. Now, with over 140 undercarriages operating across the globe for more than a decade, L&H has proven that the current L&H Omega system lasts 30% longer than OEM models, every time. To continue to set those industry-leading benchmarks, we decided to upgrade the current Omega system to leap even farther ahead of existing technologies. Here’s what we’ve accomplished.
Our proactive modifications—fully guaranteed and 100% OEM compatible—significantly reduce structural wear and machine downtime, reducing the overall cost of ownership of an L&H Omega.
Our approach to undercarriage innovations:
- We redesigned key structures and utilized upgraded materials wherever we could, ensuring that wear happens at a slower, more predictable rate.
- We evaluated the most costly pitfalls of current models and addressed these issues in our upgraded system.
- We included innovations that distinctly extend maintenance intervals, make upkeep simple, and increase overall safety.
The L&H Omega Undercarriage is leaps and bounds ahead of OEM systems. By understanding the nature of different field conditions and knowing the typical patterns of failure and stress, our engineers have developed an undercarriage that exceeds the performance of every other option on the market.
An innovative shoe design, fine-tuned to perfection
We’ve tested the strength and performance of our shoes from every angle. We upped the proportion of impact-resistant manganese steel in our shoes, increasing their density and slowing wear into a predictable linear wear pattern. Through these innovations, we’ve been able to maintain an unprecedented 0.001% failure rate, making our shoes the most reliable option available.
Deep engagement where you need it
Our innovative shoe system features deep engagement and a stable pitch that fits deep into drive tines. This helps to create a larger contact area, which reduces wear on tumblers and other key components. We’ve also improved the internal core of our shoe system to prevent cracking on track pads, and integrated larger pins and wider hinges to extend track life.
A straddle-mount front idler that lasts 3x the OEM design
Our straddle mount design simplifies inspections and maintenance, and extends the typical maintenance interval up to three times that of the OEM design. This innovation opens the door to additional bushing, which reduces the bearing stress by 50% and eliminates the need to split the tracks to replace them.
Roller innovations that mean greater productivity for your fleet
Our 1-piece, forged, lower rollers last 30% longer than other conventional brands, thanks to our innovative heat treatment process. We’ve also given additional clearance to our undercarriage by creating an elevated roller path––an enhancement that provides more maneuverability in poor operating conditions and helps better distribute the weight of the machine.
A transmission system that can’t be beat
The L&H Omega propel transmission increases torque by 50-65%, enabling your machine to move through any terrain with ease.
Impact To Operations
The upgraded L&H Omega Undercarriage means greater productivity for your fleet, every time. Our proactive modifications—fully guaranteed and 100% OEM compatible—significantly reduce structural wear and machine downtime, reducing the overall cost of ownership of an L&H Omega and sustaining a truly remarkable return on investment.
Proven in every terrain
From the oil sands in Canada to the copper mines of Chile, each mining operation has unique terrain which plays an important role in how shovel undercarriages wear and how to plan for maintenance. When you choose an L&H Omega Undercarriage, you can trust that it will be powerful enough to excel in your mine’s conditions, whatever the terrain.
Maintenance made simple
The L&H Omega Undercarriage has raised the bar in the industry by making design improvements that lengthen maintenance intervals and decrease total cost-per-hour. Our straddle mount improvements collectively cut out 8 hours or more of maintenance time, while all consumable-type components have been moved to the outside of the side frame, reducing how often the track must be split for upkeep.
An improved lift system built for safety
We developed a 1,400-ton capacity, multi-point, hydraulic lift system which requires no major shovel disassembly, facilitates safe and easy maintenance access, and makes undercarriage replacements simple.
Worldwide, 24/7 field services
Our experienced field crews are available around the clock to install, maintain, repair and rebuild our L&H Omega Undercarriage, as well as other assemblies for electric rope shovels. We also audit the machinery we sell to our customers every three months, which helps us ensure that L&H components are operating smoothly, and gives us an opportunity to better predict their expected life in your particular mine.
One of our customers in the Powder River Basin did a head-to-head test of our L&H Omega Undercarriage against a competitor’s undercarriage by running them on two identical machines operating in the same mine.
The results are pretty compelling:
Mine site: Powder River Basin
Mine type: Coal
Machine type: 4100XPC
Run time until undercarriage replacement required:
OEM Undercarriage: 23,396 hour
L&H Omega Undercarriage: 36,162 hours
Performance difference: 12,766 hours = 531 days = 1.5 years
Yes, you read that right. 1.5 years.
Same machine type, same conditions. But one machine (the one running L&H Omega technology) employed the right undercarriage for the operating environment – an undercarriage that also featured major design improvements which extend assembly life under any condition. The cost-per-hour of our competitors just cannot compare.
Look past the price tag and the advantages are clear: no undercarriage will perform better or give you a greater return on your investment than ours.
