FAQs
Q1: Can I order just 1 set for prototype development?
A: Yes, absolutely! We fully support MOQ = 1 set for custom engineering projects. Whether you are building a single prototype or gearing up for mass production, we provide the exact same engineering rigor and quality control.
Q2: Can I change a steel track undercarriage to a rubber track later on the same frame?
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.
Q3: What parameters do I need to provide for a custom quote?
A: To give you an accurate drawing and quote, we simply need: (1) Total machine payload, (2) Preferred track type (steel or rubber), (3) Transport dimension limits, (4) Operating speed & terrain conditions, and (5) Hydraulic system parameters
Q4: What is your warranty and technical support policy?
A: We offer a 12-month or 1,000-working-hour warranty covering all structural parts and major components. Our engineers provide 24/7 video and CAD assistance for integration, and spare parts ship globally within 7 days.
