Product Introduction
1. Product Overview
We develop and produce heavy-duty replacement spare parts that perfectly match the operating demands of Shacman and Sinotruk large commercial trucks. After repeated road condition simulation testing, these components maintain stable running status in long-term heavy-load scenarios and effectively extend the overall replacement cycle for vehicle wearing parts.
2. Raw Materials & Fabrication Standards
The core structure is forged from high tensile alloy steel, paired with high-density rubber accessories resistant to friction and aging. All production procedures follow the dimensional drawings of original vehicle manufacturers. Each finished piece is calibrated manually during processing, so end users can complete direct assembly without trimming, drilling or other secondary modifications on site.
3. Practical Advantages in Actual Use
Strong friction and corrosion resistance, adapting to muddy, dusty and bumpy construction road surfaces
Stable mechanical coordination during operation, cutting down unexpected roadside breakdowns for fleet vehicles
Direct delivery from our production workshop removes intermediate traders, helping overseas buyers control procurement costs
Each batch undergoes dimension measurement, appearance check and pressure testing before being packed for outbound delivery
4. Applicable Scope & After-Sales Arrangement
These replacement parts are widely installed on long-distance freight tractors, engineering dumper trucks and various bulk cargo transport vehicles. We do not set rigid minimum order quantities, so clients can place small trial orders first to verify quality, with more favorable unit prices for full container loads. We can pack goods in standard neutral export cartons or print customer trademarks and outer box designs on request. For any defects caused by production flaws within 12 months after shipment, we support corresponding after-sales solutions.
FAQ
Q1: Can these parts be mounted directly on original truck chassis? A: Yes. Every product is made according to the original vehicle's size blueprint. Workers can finish the whole installation process with basic hand tools without any structural alteration.
Q2: How do your materials perform under harsh working environments? A: The main alloy body is treated with anti-rust coating, and the rubber auxiliary parts are formulated to withstand high temperature and intense friction. They hold up well under continuous heavy-load driving for construction and mining fleets.
Q3: Do you accept small trial orders for quality testing? A: We welcome trial purchases of small quantities. Unit pricing will be adjusted accordingly if customers place large-volume repeat orders later.
Q4: What quality checks will the goods go through before shipment? A: Our QC team checks overall size, surface finish and assembly tightness one by one. Only products that pass all manual checks will be labeled and packed for international logistics.
Q5: Is customized outer packaging available for resale? A: Certainly. Apart from plain neutral export cartons, we can print client's brand logos, part numbers and shipping marks on packages as per submitted artwork files.
