A major Nigerian client visited Aorun’s Liangshan factory in person to inspect the Haohan truck-mounted crane.

AORUN | 2026-6-10

Accompanied by Aorun’s professional engineering and technical team specializing in overseas trade, the client conducted a comprehensive, high-precision on-site inspection and functional operation drill of the Hohan heavy-duty truck-mounted crane scheduled for delivery, visiting the final assembly workshop, welding and tooling line, and dynamic testing grounds.

For large-scale overseas procurement of construction machinery, genuine manufacturing expertise and transparent post-production quality inspections are the key factors that clinch major deals. A client from Nigeria recently visited Aorun’s Liangshan factory to conduct a comprehensive, multi-dimensional assessment of the product's dynamic mechanical performance:

Inspection of full-weld tooling processes: The client visited the structural welding workshop to witness firsthand the fully automated jig positioning and CNC full-welding processes used for the truck-mounted crane's sub-frame structure. The welds were uniform and free of slag inclusions, ensuring the structural components possess excellent resistance to stress concentration under extreme loads.

Lifting load limit testing: At the factory's dedicated testing ground, engineers demonstrated the crane's dynamic lifting operations. Under the client's direct observation, the crane underwent tests involving heavy-load lifting with the boom fully extended, a 300-degree full-rotation maneuver, and stability checks for the hydraulic dual-locking system. The full-box-section hydraulic main and rear outriggers provided secure ground support, while the vehicle maintained a low, stable center of gravity, demonstrating exceptional structural balance and safety margins.

At the fleet staging area, Aorun’s technical lead explained to the Nigerian client the mechanical design features that make this model ideally suited to West African operating conditions:

Full-length integrated heavy-duty sub-frame: To withstand the intense, complex alternating lateral and longitudinal stresses generated by boom rotation and luffing during lifting operations, the vehicle utilizes a high-tensile, dual-layer main frame integrated with a seamless, full-length sub-frame. This design completely eliminates the risk of fatigue-induced deformation in the truck chassis caused by prolonged, heavy-load lifting.

High-rigidity hexagonal boom structure: Compatible with premium international straight-arm or articulated cranes, the boom is cold-formed from a single piece of high-strength alloy steel into a hexagonal profile that offers superior resistance to bending. Paired with a multi-section, synchronously extending hydraulic main boom, the unit delivers high operational efficiency and exceptional precision during fine-control lifting maneuvers.

Given the severe electrochemical corrosion caused to steel by the tropical monsoon climate—characterized by high humidity and intense salt spray—at Nigeria’s Apapa Port and coastal regions, the Aorun quality control team implemented a rigorous "marine salt spray physical barrier" treatment following on-site verification with the client:

Multi-layer high-gloss polyurethane baked coating: The entire vehicle surface (including the truck-mounted crane boom, flatbed, and chassis) underwent meticulous shot-blasting for rust removal and the application of a zinc-rich primer, followed by the high-temperature baking of a high-gloss, anti-corrosive polyurethane finish. The coating offers exceptional adhesion, effectively withstanding the physical and chemical degradation caused by high-concentration coastal salt spray and intense tropical UV radiation.

Heavy-duty marine-grade anti-corrosion wax application: Prior to port delivery and shipment, specialized export engineers applied heavy-duty, marine-grade anti-corrosion wax to critical areas—including chassis main beams, steering knuckles, drive shafts, air brake valve housings, and crane hydraulic lines—ensuring complete coverage. For the sea voyage, premium Roll-on/Roll-off (RO-RO) vessels were selected to transport the vehicle within the cargo hold, thereby completely blocking exposure to the physical and electrochemical effects of marine salt spray.

Q: What business conveniences does Aorun offer if we have long-term operations in other Chinese cities?

A: This is precisely the advantage of Aorun’s "front-end sales, back-end manufacturing" collaborative supply chain model. In addition to visiting our production base in Liangshan, Jining (Shandong) for on-site vehicle inspections, overseas buyers can visit any of our offline locations—such as our business center in Guangzhou, office in Yiwu, or representative office in Jinan. Each office is equipped with a high-definition digital display system that enables real-time video links to the modern Liangshan factory. Bilingual engineers can provide live demonstrations of specific mechanical details (such as spring brake pressure retention or hydraulic lifting systems) right on screen, saving you the trouble of long-distance travel between cities while allowing you to handle business settlements and factory-level quality checks seamlessly.

Q: Are spare parts for Hohan truck-mounted cranes easy to find locally in Nigeria? Is maintenance convenient?

A: Hohan fully leverages Sinotruk’s extensive after-sales parts network across Africa. Components such as engine parts, Fast Gear transmissions, and heavy-duty drive axle parts—including filter elements, oil seals, brake pads, and air pump lines—are readily available in the truck parts markets of Lagos, Kano, Abuja, and major logistics hubs. Even mechanics at inland infrastructure sites possess the necessary expertise for repairs, making routine maintenance straightforward and accessible. Additionally, Aorun provides a complimentary emergency kit with every vehicle, containing genuine, frequently replaced parts such as filters and seals.
