Founded in Deyang City, Sichuan Province, China, Deyang Hongkai Auto Trading Co., Ltd. has grown from a domestic truck sales company to a global pioneer in custom heavy vehicle and dump truck bucket manufacturing. Focusing on truck trading and heavy-duty chassis modification in our early phases, we successfully established an extensive customer network and advanced metalwork facilities.
Today, our custom dump truck buckets and modified truck tipper solutions represent the pinnacle of Chinese heavy-industry craftsmanship, utilizing robotic assembly and high-strength metallurgical engineering to service global operations in mining, roadbuilding, and cargo transport.

A technical exploration into modern steel grades, load fatigue reduction, and high-impact structural geometry.
We source certified Hardox® 450, NM450, and Q345B steel sheets to guarantee optimal yield strength and Brinell hardness ratings. Our dump buckets balance structural elasticity with surface hardness, avoiding fracture cracking under high-impact mining discharge cycles.
Modern fleet efficiency requires tailored bucket designs. Our U-shape buckets prevent sticky clay/mud adhesion, lower the load's center of gravity for safer hauling, and reduce deadweight by 15-20% to maximize legal payload capacities.
Our heavy-duty welding processes utilize advanced Submerged Arc Welding and gas metal arc welding (GMAW) under controlled thermal conditions. This reduces stress concentrations along primary critical seams, ensuring structural longevity.
How our custom manufacturing line addresses unique industrial environments globally.
For operations transporting abrasive granite, iron ore, or large limestone boulders, our mining-spec buckets incorporate thick bottom liners, rock deflectors, and heavy-duty wear ribs. This configuration minimizes structural deformation during high-drop payload drops from excavators.
Urban contractors require dust containment, tight turning clearances, and lightweight structures for regulatory compliance. Our medium-duty, high-tensile steel bodies feature automated sealing tailgates, tarp rollers, and optimized side profiles for clean material discharge.
For low-density cargo like agricultural grain, woodchips, and municipal waste, volume capacity is critical. We produce drop-side and extended-height aluminum/light-steel alloy bodies that maximize volumetric capacity up to 35m³ without violating axle weight limits.
High-efficiency power systems, predictive powertrain controls, intelligent thermal management, and flow field optimizations define our chassis alignments.
Why manufacturing in Sichuan, China delivers unmatched dimensional tolerances and material value.
Our facility employs high-capacity CNC fiber laser cutting systems and 1000-ton hydraulic press brakes. This ensures that each steel sheet is cut and shaped with sub-millimeter accuracy, preserving the structural integrity of bent corners without micro-cracking.
Critical structural joints of the dump bucket are welded by automated robotic systems. This achieves uniform penetration and seamless weld beads, removing human error and minimizing risk of weld failure under severe shock loading.
Every bucket undergoes an intensive surface preparation process: thorough steel shot blasting to class Sa 2.5, followed by the application of marine-grade epoxy primers and polyurethane topcoats. This treatment protects the equipment from rust and abrasion in harsh humid, coastal, or acidic mining environments.
Located in Deyang's heavy machinery manufacturing corridor, we benefit from direct logistics connections, domestic steel processing hubs, and close integration with global port routes. This allows us to offer shorter production lead times and lower freight costs for worldwide export.
We collaborate with global engineering and logistics companies to distribute and support our heavy machinery products.
Aligning container engineering with international logistics standards, autonomous machinery, and carbon reduction mandates.
We are piloting integrated hydraulic strain gauge sensors within the support hinges of our custom dump buckets. These sensors broadcast real-time payload metrics directly to the driver's cabin and the fleet manager's dashboard, preventing overload violations and tracking productivity.
By refining the front cab guard and integrating side-deflecting panels, our new U-shaped buckets reduce aerodynamic drag coefficients by up to 8% when returning empty. This optimization delivers measurable fuel savings for long-haul operators.
Partnering with domestic metallurgy research institutes, we are developing next-generation high-strength aluminum-lithium alloys. These materials aim to match the impact resistance of standard structural steel while reducing body weight by 40% for light-density transport.
We provide end-to-end ODM/OEM services for heavy vehicle chassis modifications, with exports serving markets worldwide.
We work to understand your transportation needs—such as cargo characteristics, typical routes, payload requirements, and environmental factors—to recommend the ideal truck models, steel grades, and bucket configurations.
We offer 24-hour technical support to resolve operational issues. We also provide offline or online training programs for drivers and maintenance technicians to help improve truck operations and equipment life cycles.
Prior to shipment, every truck and dump bucket undergoes rigorous inspection, including structural seam checks, hydraulic cycle tests, paint quality validation, and safety system adjustments to ensure they arrive ready for operation.
Our structures are backed by a comprehensive warranty policy outlining coverage scope and duration. We maintain inventory support for hydraulic cylinders, hinges, and tailgate seals to ensure minimal operational downtime.

Emily Johnson
Logistics Director, United States"As a professional involved in long-distance logistics transportation for many years, I am demanding of my trucks. Purchasing custom fleets configured with HONGKAI bodies was one of the smartest business decisions I've made recently. The durability of their steel is exceptional."
Amara Diop
Lagos-Dakar Long-Haul Coordinator"Tackling Africa's diverse roads requires robust suspension and heavy-duty steel. HONGKAI's dump truck buckets handle constant gravel loading and heat like a champ. The reinforced bottom plate makes it our go-to for cross-border operations."
Johannes Kruger
Mining Logistics Manager, Zambia"Operating a mining supply business, our trucks haul heavy equipment daily. The torque of the Shacman chassis combined with the custom U-shape HONGKAI rock bucket makes our operations highly efficient. Highly recommended for abrasive mineral transport."
