Save Thousands on Equipment Maintenance: Invest in Wheel Tire Protection Tracks for Fleet

Muddy haul roads, soft ground and rain-soaked construction sites are the biggest enemies of wheeled transport vehicles. Spinning tires, sunken axles and stranded trucks translate directly into lost working hours and expensive rescue operations. The antiskid crawler is a bolt-on track system that converts the inflatable tires of a double axle engineering vehicle into a wide, load-spreading crawler surface. With stock units available for the 1200-20 standard tire specification, now is the right moment to secure traction before your next wet season.

What Is an Antiskid Crawler?

An antiskid crawler, also known as a tire protection track or anti-skid track chain, is a heavy-duty assembly of cast main plates connected by high-strength bolts, wrapped directly around the inflatable tires of an engineering vehicle. Once installed, the crawler carries the vehicle load on a much larger ground contact area than the bare tire, dramatically reducing ground pressure and preventing the wheel from digging into soft soil.

Unlike permanent rubber track conversions, the antiskid crawler is a removable accessory. It can be fitted before entering a muddy section and removed for road transfer, giving the same truck two operating modes without any structural modification. This makes it a practical, low-investment solution for earthwork sites, mines, quarries, tunnel access roads and any project where the haul route is unpaved.

Key Specifications of Our Antiskid Crawler

Our antiskid crawlers are produced for the 1200-20 standard inflatable tire, the most widely used tire size on double axle engineering vehicles, ensuring a direct fit for the majority of site dump trucks and transport vehicles.

Why Choose a Cast Steel Antiskid Crawler?

1. 31Mn2Si Alloy Steel Main Plate
The main plate is manufactured from 31Mn2Si alloy structural steel, the same grade family used for mining chain and track components. It combines high tensile strength with excellent wear resistance, so the plate holds its shape after repeated impact against rock, rebar and frozen ground.

2. Grade 12.9 High-Strength Bolts
Every joint is fastened with grade 12.9 bolts, the highest common strength class for fasteners. Bolt failure is the number one cause of track loss on site; using 12.9 grade hardware keeps the 53 sections locked together under repeated tension and shock loading.

3. Casting Process for Structural Integrity
The plates are produced as casting parts rather than bent or welded sheet. The integral cast body has no weld seams to crack, delivering consistent thickness at the grouser and a longer service life under continuous abrasive wear.

4. Anti-Sinking Through Wider Ground Contact
By spreading vehicle weight across the full crawler footprint instead of a narrow tire patch, ground pressure drops sharply. The vehicle floats over mud, sand and soft backfill instead of sinking, eliminating most towing and rescue events.

5. Anti-Skid and Anti-Puncture Tire Protection
The aggressive plate profile bites into slippery surfaces for positive traction on gradients and wet clay, while the steel plates shield the tire carcass from sharp stone, scrap steel and demolition debris, significantly extending expensive tire life.

6. 53-Section Modular Structure for Easy Repair
Each unit consists of 53 individual sections. A damaged plate can be unbolted and replaced on site within minutes, without scrapping the whole crawler, keeping spare-part cost and downtime to a minimum.

Practical Applications

The antiskid crawler is particularly well-suited for:

Muddy construction site haul roads - maintaining transport cycles during and after rainfall

Earthwork and foundation projects - operating on soft backfill and unconsolidated ground

Mine and quarry access routes - protecting tires from sharp rock and preventing sidewall cuts

Tunnel and slope engineering - stable traction on wet, sloped and uneven approach roads

Winter and frozen ground operations - reliable grip on icy and snow-covered surfaces

Sand, beach and reclamation areas - preventing wheel sinking in loose granular ground

Key Considerations for Selection

Tire Specification Matching - The standard unit is designed for 1200-20 inflatable tires. Confirm your tire size before ordering; other sizes can be produced according to your tire drawing.

Vehicle Configuration - Standard supply targets double axle engineering vehicles. Advise the axle layout, for example the common four-front eight-rear configuration, so that the quantity of units is calculated correctly.

Load and Site Conditions - Heavier payloads and sharper aggregate accelerate plate wear; discuss your typical load and ground condition so we can recommend the suitable plate thickness.

Handling and Storage - Each unit weighs 750 kg. Ensure a loader or small crane is available on site for installation and removal, and store the crawler on dry ground to avoid corrosion between working seasons.

Spare Parts Support - Confirm long-term availability of replacement plates, bolts and nuts, so a single damaged section never immobilises the complete set.

Expert Recommendation

For most site transport fleets running double axle vehicles on 1200-20 tires, we recommend equipping the drive axles first. The 750 kg cast crawler with 31Mn2Si main plates and grade 12.9 bolts delivers the best balance between traction gain and handling weight. Fleets working year-round on unpaved ground usually recover the investment within a single wet season through avoided towing charges, reduced tire replacement and uninterrupted haul cycles.

Frequently Asked Questions

Which tire size does this antiskid crawler fit?

The standard model fits 1200-20 standard inflatable tires used on double axle engineering vehicles. Other tire specifications can be manufactured on request based on your tire dimensions.

How many sections does one crawler unit contain?

Each unit is assembled from 53 sections, connected by main plates with matching bolts and nuts, forming a complete closed track around the tire.

What material and bolt grade are used?

Main plates are cast from 31Mn2Si alloy structural steel and all connections use grade 12.9 high-strength bolts for maximum reliability under shock load.

How heavy is one crawler unit?

One complete unit weighs approximately 750 kg. Mechanical assistance such as a loader is recommended for installation and removal.

What problems does the crawler actually solve?

It prevents skidding on wet and sloped ground, stops the vehicle sinking into mud and soft soil, and protects tires from punctures caused by sharp rock and site debris.

Can the crawler be removed for road transfer?

Yes. It is a bolt-on accessory, not a permanent conversion, so it can be fitted for off-road sections and removed when the vehicle returns to paved roads.
