Crane Track Shoe
30 Years of Experience – Engineering Safety & Reliability into Every Crawler Crane Undercarriage Parts.
What are track shoes?
Track shoes are located at the bottom of the crane undercarriage, surrounding the sprockets, track rollers, idler rollers, and carrier rollers. Multiple track shoes are connected by track pins to form a loop track assembly that surrounds the entire tracked crane undercarriage. They are high-wear crane undercarriage parts, typically made of high-strength alloy steel to withstand immense pressure and wear.
Core Functions:
-
Support Weight: Directly in contact with the ground, bearing the entire weight of the crane.
-
Provide Traction: Increases friction with the ground, driving the tracked crane forward, backward, and turning, preventing slippage.
- Protect the Ground: Distributes the weight of the machine over a larger area, reducing ground pressure and preventing the machine from sinking into soft ground. It also protects paved surfaces from damage.
- Protect the Undercarriage: As a wear component, it withstands direct impact and wear from the ground, protecting more expensive internal components such as the drive sprockets, track rollers, and sprockets.

Production Process
1. Mold Making: Precision molds are made according to customer-provided drawings or original factory samples. Molds are typically made of high-precision aluminum alloy to ensure the dimensional accuracy of the crane track shoe.
2. Casting: Molten alloy steel (such as 35SiMn, 40Mn2, 28CrMnMo, etc.) is poured into the sand mold at high temperature. The pouring temperature and speed are strictly controlled to ensure that the molten metal fully fills the mold cavity.
3. Cleaning & Riser Removal: After the casting cools, the molding sand adhering to the surface is removed, and the risers and gates are cut away, giving the crane track pads a preliminary shape.
4. Rough Machining: Preliminary machining of the casting is performed, including milling the rough surface and rough drilling, in preparation for subsequent heat treatment.
5. Overall Quenching & Tempering
Quenching: Heating the track pads to a specific temperature followed by rapid cooling improves hardness and strength.
High-Temperature Tempering: Reheating to an appropriate temperature followed by cooling eliminates internal stress, increases toughness, and prevents cracking during use.
6. Mechanical Properties Testing
Tensile Test: Tests tensile strength and yield strength.
Impact Test: Tests impact toughness.
Hardness Test: Ensures core hardness meets design requirements (typically 32-38 HRC).
7. Surface Hardening
Secondary induction hardening is performed on critical wear surfaces in contact with the crawler track pads, track rollers, and drive wheels to achieve a surface hardness of 52-62 HRC and a hardened layer depth of 4-6 mm, significantly improving wear resistance.
8. Finishing
Precision milling: Ensures the flatness of the mounting surface.
Precision boring of pin holes: Improves coaxiality using boring technology, ensuring a perfect match between the crawler track shoe and the pin.
9. Non-Destructive Testing
Cutting test: Inspects for internal casting defects.
Ultrasonic testing: Inspects for internal defects such as cracks and porosity.
Magnetic particle testing: Inspects for surface micro-cracks.
10. Painting for Rust Prevention
Automated painting workshop, environmentally friendly. Standard crawler crane track pad color is black, but custom colors are available upon request.
Customer Feedback
Manitowoc 12000 Track Shoe
The customer, a New Zealand-based crane company, contacted us in November 2026 to request a set of track shoes for their Manitowoc 12000 cranes. As this was their first time purchasing tracked crane chassis parts from China, their biggest concern was inaccurate sizing and the hassle of returns and exchanges. To alleviate their concerns, we sent them drawings, and their engineer confirmed the dimensions before placing the order.
Upon arrival, the customer happily reported that the track shoes installed very smoothly, and our dimensions matched the other chassis parts perfectly! Below is a screenshot of the customer’s feedback:
Sumitomo SC700 Track Shoe
The customer, a Thai construction company, owns five or six Sumitomo SC700 cranes. They had previously purchased aftermarket parts, which resulted in peeling and cracking of the rails within six months. This time, they wanted a reliable track shoe supplier. We sent them the production details and inspection reports before they placed their order. The image below shows the track pads’ condition three months after the customer received the goods. The customer reported, “The track pads have been installed and used for three months now. The soil at the construction site is hard, with a lot of gravel, and the pads look great so far, with no signs of peeling.”
How to extend the service life of crane track pads?
Choose the right material based on the working conditions.
Different working conditions require different wear resistance and toughness from the track pads. For high-wear environments such as mines and quarries, it is recommended to choose 35SiMn alloy steel track pads that have undergone surface hardening and quenching. For ordinary construction sites, standard materials with a higher cost-performance ratio can be used. Different tonnage tracked cranes require different materials; typically, large-tonnage crane track shoes will have added Cr, Mn, Mo, etc.
Avoid sharp turns on the spot.
Sharp turns on the spot cause severe friction between the crane track pads and the ground, concentrating stress on the track surface and accelerating wear. When turning is necessary, try to turn with a small radius and slow speed, or combine it with small forward and backward movements to reduce continuous friction at a single point.
Clean tracks promptly.
Gravel, clay, and concrete debris stuck in the gaps between crawler track plates or sprocket teeth will accelerate track plate wear. Simple cleaning after each day’s work prevents hardening and effectively reduces wear.
Regularly check bolts to prevent loosening.
Loose track plate connecting bolts will accelerate pin hole wear and bolt breakage. Check the torque daily for the first week after new track plates are installed, and then conduct routine checks weekly. Tighten any loose bolts promptly to maintain the overall stability of the track plates.
Check the condition of the bottom rollers and sprockets.
Severely worn sprocket teeth will change the meshing angle, leading to abnormal wear on the track chain surface; jammed bottom rollers will cause excessive localized stress on the track plates. Regularly check the condition of the track crane undercarriage parts; replace any damaged parts promptly, otherwise it will accelerate damage to other components.
Regularly rotate left and right track plates.
When cranes are operating, the turning direction is usually fixed, and one side of the crane track shoe often wears faster than the other. If equipment permits, the left and right crawler crane track pads can be periodically swapped to ensure more even wear and extend the replacement cycle.
FAQ
Q1: When should crane track pads be replaced?
A: Replacement is recommended when the track chain surface wears close to the pin hole height, shows obvious cracks, or the crane track shoe is deformed and affects walking stability.
Q2: Are special tools required for track shoe installation?
A: Yes. Track pin removal and installation tools and a torque wrench are required. If replacing the entire set, it is recommended to have it done by a professional to ensure the bolt torque is correct and the track tension is appropriate.
Q3: Are your crawler track pads original equipment manufacturer (OEM) or aftermarket parts?
A: We are a professional aftermarket crane undercarriage parts supplier. Our crawler crane parts are manufactured strictly according to OEM specifications, with dimensions and performance identical to OEM parts, but at a more competitive price.
Q4: What payment methods do you accept?
A: We accept a variety of payment methods, including T/T, L/C, Western Union, PayPal, and more. For long-term cooperative customers, more flexible payment terms can be negotiated based on order value and history.
Q5: How to place an order?
A: You only need to provide the crane model or the dimensions of your old crane track pads, and we will match the original specifications and send you a quote.
