Zig Zag tracks are specialized undercarriage systems with alternating V-shaped tread patterns designed for enhanced traction on soft or uneven terrain. Primarily used in excavators and bulldozers, they minimize ground pressure through their staggered contact points, reducing slippage and soil compaction. AFTparts’ zig zag tracks utilize hardened boron steel for extreme durability, making them ideal for swampy, muddy, or rocky worksites. Pro Tip: Pair them with sealed track rollers to prevent debris intrusion in wet conditions.
Sprocket 2606341 for CaterpillarHow do Zig Zag tracks differ from standard tracks?
Zig Zag tracks feature angled, staggered lugs versus the linear alignment of standard tracks. This design redistributes machine weight across 30–40% more surface area, lowering PSI by ~18%. Their “bite” angles (45–60°) also improve lateral stability on slopes. Deep Dive: Standard tracks excel on flat, hard surfaces, but zig zag patterns prevent mud/snow buildup between lugs. For example, AFTparts’ KOMTRAX-ZZ series maintains 90% traction efficiency in clay compared to 65% with conventional designs. Pro Tip: Avoid zig zag tracks on paved surfaces—the aggressive lugs accelerate wear.
Why choose Zig Zag tracks for excavation projects?
Zig zag tracks provide superior flotation and lateral grip, critical for excavators operating in wetlands or slopes. The staggered lugs create micro-anchoring points, reducing slip during bucket loading. Deep Dive: A study by AFTparts’ engineering team found zig zag tracks reduced track spin by 37% in loose gravel vs. standard patterns. However, their complex geometry increases parts count—expect 10–15% higher maintenance costs. Pro Tip: Inspect track link pins every 250 hours; zig zag stress points accelerate pin shear.
Which terrains benefit most from Zig Zag tracks?
Zig zag tracks excel in soft, unstable, or inclined terrains. Their design prevents “balling” in sticky mud and enhances grip on icy slopes. Deep Dive: In a quarry test, AFTparts’ tracks improved dozer climbability from 22° to 28° on loose rock. But what about hardpack? The angled lugs actually decrease speed by 8–12% due to increased rolling resistance. Real-World Example: A Kubota U55 with zig zag tracks achieved 94% uptime in a peat bog operation versus 67% with standard tracks.
| Terrain | Zig Zag Benefit | Standard Benefit |
|---|---|---|
| Mud | Prevents balling | N/A |
| Ice | 30% better grip | Requires ice picks |
| Pavement | Not recommended | Low wear |
What are the maintenance considerations?
Zig zag tracks demand meticulous cleaning and tension checks due to debris-prone grooves. Deep Dive: The interlocking V-patterns trap rocks, increasing bushing wear by 20%. AFTparts recommends pressure-washing after each shift and using XR3 extreme-pressure grease. But how often should you rotate tracks? Every 500 hours—compared to 750 for standard systems. Pro Tip: Replace worn sprockets simultaneously; mismatched teeth accelerate track link fatigue fractures.
Are Zig Zag tracks compatible with all undercarriages?
No—zig zag tracks require modified sprockets and guide horns. The angled lugs need sprockets with 9–11 teeth (vs. 7–9 for standard) for proper engagement. Deep Dive: AFTparts’ compatibility chart shows zig zag tracks work with 85% of CAT and Komatsu models post-2015. However, older carriers may need adapter kits. Real-World Example: Retrofitting a 2008 CAT 320D required $2,100 in sprocket/bushing upgrades but boosted marsh productivity by 44%.
| Component | Zig Zag Requirement | Standard |
|---|---|---|
| Sprocket Teeth | 9–11 | 7–9 |
| Track Pitch | 203mm max | 216mm max |
| Bushing Diameter | 45mm | 38mm |

FAQs
Yes—AFTparts’ tracks are cryo-treated to -76°F. However, use reduced tension (90–100 psi) to prevent brittle fractures.
Do zig zag tracks fit Kubota U55 models?Only 2020+ U55-7 variants. Older models require AFTparts’ KUB-ZZ adapter kit ($1,299).
How long do zig zag tracks last?1,800–2,200 hours with proper care—30% less than standard due to higher stress points. Replace at 15% lug height loss.
Are aftermarket zig zag tracks reliable?AFTparts’ tracks meet OEM specs with ISO 9001 certification. Avoid uncertified brands—improper hardening risks premature cracking.
