A: We strongly recommend choosing an undercarriage with a 15% to 20% safety margin. For a 10-ton machine, a 12-ton or 13-ton rated undercarriage is ideal. This is because when your equipment is working (e.g., drilling, excavating, or crushing), it generates dynamic loads, vibration, and torque that add extra stress to the chassis. A built-in safety margin prevents premature wear and ensures structural safety on sloped or uneven terrains.
A: Standard symmetrical undercarriages assume a relatively centered weight distribution. If your machine's center of gravity is significantly shifted forward or backward (common in drilling rigs and long-boom cranes), we will customize the track roller positioning, lengthen the track frame, or shift the mounting center. This ensures even ground pressure distribution, prevents "track nose-diving" or rear digging, and extends the lifespan of the rollers.
A: For hard, abrasive rock surfaces, you should avoid single-grouser plates (which can bend or break under concentrated stone impacts) and choose heavy-duty triple-grouser or double-grouser steel track shoes. Additionally, the steel must undergo high-depth induction hardening. We also recommend adding full-length track roller guards to prevent rocks from wedging into the track chain and causing de-tracking.
A: To give you the final engineering drawing, please provide the following "Golden Six" parameters:
1.Total payload required (Weight of your upper machine + work attachments).
2.Preferred track type (Steel track or Rubber track).
3.Available hydraulic system parameters (Max flow rate L/min and Max pressure MPa).
4.Dimension limits (Max allowable total width and length for transport limits).
5.Working speed requirement (Low speed/High speed).
6.Detailed terrain description (e.g., hard rock, mud, sand, slope angles).
A: Standard steel and rubber become brittle, and standard grease freezes in extreme cold. For temperatures below -25°C, we upgrade the selection to low-temperature alloy steel for the frame, utilize specialized low-temperature seals for all rollers, and fill the system with synthetic anti-freezing lubricants. For rubber tracks, we use a custom low-temperature-resistant rubber compound to prevent cracking.
A: With Middle Frame (Integrated): Best if your equipment needs a solid, complete chassis base. You just bolt or weld your upper frame directly onto our crossbeam. It ensures perfect parallel alignment between the two tracks. Without Middle Frame (Two Independent Tracks): Ideal if your equipment already has a robust lower chassis frame. You can simply mount our two independent side frames directly onto your structure, reducing shipping volume and saving costs.
A: Generally, no. The internal guiding and driving components are fundamentally different. Steel tracks ride on steel rollers via a chain link, driven by a sprocket that meshes with the chain pins. Rubber tracks use smooth-surface rollers that ride inside a rubber carcass guide, driven by a sprocket that meshes with internal iron teeth. The frame geometries, roller heights, and sprocket profiles are distinct, so the track type must be decided during the initial selection phase.
A: Our engineering team will do the calculations for you. You just need to provide your pump's maximum working pressure (MPa or PSI) and output flow rate (L/min or GPM). We will select a hydraulic motor with the exact displacement needed to match your pump, ensuring the undercarriage achieves the desired travel speed and climbing torque without overloading or overheating your hydraulic system.
A: We fully support MOQ = 1 unit for customized projects. We understand that many engineering machinery projects, prototyping phases, or specialized drilling rigs require only a single, highly tailored undercarriage. We treat every single-unit custom project with the same rigorous engineering and quality control as an order for a hundred units.
A: The most critical factor is the Total Operational Weight of your machinery plus its maximum working payload (such as drilling torque, bucket capacity, or crusher load). The undercarriage must be engineered with a sufficient safety margin to handle both static weight and dynamic impact forces during operation without frame deformation.
A: Track shoe selection depends entirely on your working terrain to balance ground pressure and component stress:
1. Wide Shoes: Ideal for soft, muddy, or swampy terrains to maximize flotation and prevent sinking.
2. Narrow Shoes: Ideal for hard rock or abrasive conditions. Wide shoes on hard ground will experience severe edge bending stress, leading to cracked links or loose hardware.
A: It depends on your traction and maneuverability requirements:
1. Single Grouser: Best for extreme slopes and soft mud where maximum soil penetration and aggressive grip are needed.
2. Double/Triple Grouser: Best for flat rock, gravel, or concrete sub-bases. They distribute weight evenly, offer lower turning resistance, and minimize ground damage.
3. Mud-Serrated (Excavated): Best for sticky clay or wetlands, featuring center cutouts to automatically eject packed debris and prevent tension spikes.
A: Yes, absolute customization is our core strength. We design the cross-beam mounting interfaces to perfectly match your upper chassis structure and center of gravity. Additionally, we source and integrate dual-speed travel motors (final drives) that precisely match your hydraulic flow, pressure, and required tractive effort (gradeability)
