Crawler Tracks in Mobile Crushing and Screening
Mobility, Stability, and Expert Usage
The most defining difference between mobile and stationary crushing equipment is, without question, mobility. In mobile systems, this is made possible by a pair of heavy-duty crawler tracks mounted under the chassis. These tracks are not just an accessory - they are the foundation that makes modern mobile crushing and screening possible.
At Boratas mobile crushing and screening, we select and implement some of the highest quality crawler track systems in the industry. The entire performance, usability, and safety of a mobile machine depend on how well its tracks function. Whether you’re navigating rocky terrain, climbing gradients, or repositioning between jobs, your crawler system is working under immense pressure, literally.
In this article, we explore how crawler tracks work, what makes them critical to mobile operations, and offer valuable usage and maintenance tips for operators in the field.
What Are Crawler Tracks?
Crawler tracks - also known as undercarriages or track chassis - consist of two continuous loops of durable steel or reinforced rubber track links. These are driven independently by hydraulic motors, allowing the machine to move forward, backward, or pivot on the spot.
Each crawler track system includes key components such as:
• Drive sprockets
• Rollers and idlers
• Track chains or shoes
• Hydraulic drive motors
• A reinforced track frame
• Track tensioning mechanism
This system distributes the machine’s weight across a larger surface area than wheels, offering superior traction, better load distribution, and stability on uneven ground.
Why Tracks Are Critical for Crushing & Screening
1. All-Terrain Access
Tracks enable machines to navigate:
• Loose gravel, wet soil, and soft clay
• Rock piles and uneven surfaces
• Slopes and embankments
This makes mobile plants viable in remote or rugged jobsites without needing extensive preparation.
2. Deployment Flexibility
Machines can be unloaded from trailers and driven directly into position. They can also be repositioned with ease throughout the day as site layouts change; saving time, equipment, and labor.
3. Safe and Stable Operation
Crawler tracks offer a low center of gravity and a wide footprint. This ensures stability when feeding material, screening at full load, or operating on a slope.
4. Independence
No cranes, loaders, or towing equipment are required. Tracks allow the machine to move itself with control and precision, even in challenging conditions.
Boratas Mobile’s Track System Design
At Boratas, every mobile crusher and screener with a tracked undercarriage is built to thrive in demanding jobsite conditions. Our design priorities include:
• Reinforced, low-flex chassis frames
• Premium hydraulic drive motors
• Easy-to-adjust track tensioners
• Modular track components for quick service
• Compatibility with wireless remote control systems
We understand that the track system doesn’t just carry the machine, but it carries your entire operation. That’s why we equip our units with crawler systems matched to the weight class, working conditions, and mobility demands of each model.
Real-World Usage Tips for Crawler Tracks
Proper use of crawler tracks extends their life, improves safety, and reduces maintenance costs. Below are some general tips every operator should follow:
Always:
• Park the machine on flat, level ground. If on a slope, block the tracks securely.
• Ensure the ground surface can support the full weight of the machine.
• Move the machine at least 10 meters in each direction daily to prevent chain seizure.
• Clear debris around the tracks before moving the machine.
• Check that tracks aren’t frozen to the ground before starting.
• Inspect for oil leakage from gearboxes, rollers, or idlers before and during movement.
• Allow cooling time: stop the machine after 30 minutes of continuous tracking.
Never:
• Do not move the machine if material is built up around the tracks or drive sprockets.
• Do not track over frozen ground without clearance.
• Do not push or pull the machine using external equipment.
• Do not operate continuously for more than 30 minutes without pause.
Conditional Usage Advice
Depending on your jobsite, you may need to modify or adapt your crawler system:
• Corrosive environments: For materials that can corrode standard carbon steel, use lubricated track chains to prevent joint seizure. These are available as optional or retrofit parts.
• Extreme temperatures: Standard tracks are rated for -10°C to +40°C. Outside this range, custom track specs must be used.
• Incline travel: When climbing, drive with the idler in front (sprocket at the rear). When descending, the drive sprocket should lead for better control.
Maintenance Guidelines
Crawler tracks operate under high mechanical stress and are exposed to dust, rock fragments, moisture, and sudden impact. Consistent maintenance is crucial.
Maintenance Tips:
• Only perform service work on flat, solid ground.
• If work is required under the chassis, ensure it’s safely supported.
• Remove oil, grease, or debris regularly to prevent slippage or overheating.
• Repair any visible damage or wear immediately.
• Check for hydraulic hose leaks and oil seepage frequently.
• Use only approved lubricants—do not mix brands or types.
• Be cautious with hydraulic systems after use; oil may be extremely hot.
By incorporating these habits, operators can drastically reduce unplanned downtime and extend the operational life of both the track system and the entire machine.
Looking Ahead: The Future of Track Technology
As mobile crushing and screening continues to evolve, so too do the track systems that support it. Some of the emerging innovations include:
• Self-leveling tracks for uneven terrain
• Intelligent track control based on terrain feedback
• Sensor-based diagnostics with real-time monitoring
• Lightweight composite chains for energy efficiency
• Hybrid-electric track drives with reduced fuel consumption
Boratas is closely following these developments to bring only the most field-tested and value-adding solutions to our customers.
