FAQ
FAQ
Q:What working conditions are steel track undercarriages best suited for?
A: Steel track undercarriages excel for heavy‑duty harsh scenarios: quarry, mining, rocky terrain, desert, muddy construction sites. For pavement‑friendly urban projects, we recommend rubber track undercarriage instead.
Q:Do you provide OEM & CDM custom service for steel track undercarriage assembly?
A: Yes, full OEM & CDM service supported. We customize dimension, load capacity, hydraulic configuration, painting color, laser logo, operator manual language according to your drawing or requirements.
Q: Which parts are classified as wearing parts not covered under warranty?
A: Track shoes, track chain, rollers, idlers, sprockets are consumable wearing parts, subject to service life according to working condition. We supply spare‑part quotation list together with your order.
Q: What trade terms do you support? FOB, CIF or DDP?
A: We support FOB, CIF, CFR and DDP trade terms. Tell us your destination port or address, we calculate freight cost for you.
Q: How about ground pressure for your custom steel track chassis?
A: Ground pressure can be adjusted by changing track shoe width, frame length and total structure.
