Global Engineering Authority, Premier Chinese Manufacturing Precision, and Certified Refurbishment Ecosystem for SINOTRUK HOWO & SHACMAN Heavy Trucks.
Explore our premium select range of high-tonnage transport vehicles, custom optimized for extreme working loads and rigorous global transport routes.
Founded in the industrial heartbeat of Deyang City, Sichuan Province in 2014, Hongkai Automobile Trading Co., Ltd. (collaborating globally under the custom engineering framework of ATTP Truck Parts) has evolved from a targeted domestic vendor into a dominant transnational heavy-fleet and specialized components builder.
Our operation scale spans state-of-the-art facilities designed to deliver comprehensive mechanical oversight, from complete chassis overhauls to precision gear manufacturing. Grounded on twenty years of collective automotive intelligence, we deliver what contemporary heavy industries demand: high structural integrity, exact-tolerance component integration, and optimized total cost of ownership (TCO).
Sichuan has transitioned into an epicentre of high-performance heavy-duty machinery. ATTP integrates this regional industrial supremacy into our customized components and refurbished systems.
Our custom gears, planetary hubs, and structural suspension mounts utilize premium-grade Chinese steel configurations (e.g., high-tensile manganese alloys). We employ precise heat-treating methodologies to maximize fatigue life in intense high-torque construction operations.
Unlike rigid off-the-shelf logistics suppliers, ATTP configures heavy trucks for specific operating profiles. Whether adapting dump beds with high-thickness Wear-Resistant Steel plates (e.g., Hardox equivalent) or setting up dual-stage fuel filtrations for sub-standard diesel supply, our custom capabilities are comprehensive.
Strategically linked to the Chengdu-Europe Railway Express corridor and close to the deep-water ports of Southwest China, ATTP commands streamlined shipping rates and reliable transit times, shipping finished vehicles and custom parts directly to Africa, Central Asia, and the Middle East.
Heavy duty vehicles face starkly different mechanical hazards across various global terrains. ATTP engineered solutions address local vulnerabilities through targeted technical upgrades.
Operations in mining districts across Sub-Saharan Africa demand heavy modifications. We install reinforced leaf-spring suspensions, multi-stage heavy fuel filters to manage high sediment content, and high-clearance off-road cabins. Our SINOTRUK HOWO and SHACMAN platforms are configured specifically for remote, unpaved locations.
Extreme desert heat degrades standard seals, lubricants, and engine cooling systems. Our custom packages incorporate high-performance copper cooling radiators, desert-grade air pre-filters, and heat-resistant compound seals to ensure continuous service in temperatures exceeding 50°C.
For mountainous cold climates, we implement auxiliary engine block pre-heaters, thermal oil insulation, and cold-resistant polymer lines, preventing fuel crystallization and maintaining pneumatic brake lines in sub-zero environments.
From local commercial operations to international engineering integration, our timeline illustrates our growth as a key player in the commercial truck sector.
For international buyers and mining managers, purchasing used heavy equipment or customized parts carries operational risk. ATTP mitigates this through a structured quality control and certification process:
Our facilities regularly host international delegates, engineering partners, and mining procurement officers, building transparent, long-term B2B relationships.
Technical guidance and specification details for procurement managers and fleet operations teams.
