October 30th, a team of experts from BV, an internationally authoritative third-party inspection agency, visited MAXTECH's Nantong production base to conduct a special factory acceptance test on the custom Type I container spreaders destined for Africa. After multiple rounds of rigorous verification—including appearance inspection, dimensional accuracy measurement, paint thickness testing, and static/ load lifting tests—all indicators of the spreaders met the required standards, laying a solid foundation for smooth delivery.
The I Type container spreaders tested this time are core equipment tailored by MAXTECH to meet the special working conditions of the African client. Focusing on the local port's bulk material handling needs, the client specified that the container spreaders must be compatible with 40ft standard containers, have a safe working load (SWL) of 40 tons, and withstand Africa's harsh environment of high temperatures and high salt spray. To precisely match these requirements, the technical team developed the mechanical container spreader with specialized custom features:
·The main structure is integrally welded with Q690 high-strength alloy steel, weighing only 8.2 tons—15% lighter than conventional spreaders—greatly improving operational efficiency.
·The surface adopts a three-layer anti-corrosion process (epoxy primer + intermediate coat + polyurethane topcoat) to cope with coastal corrosion in Africa.
·Wear-resistant liners are added to key stress-bearing parts, extending the service life by more than 3 times.
At the test site, the BV expert conducted comprehensive inspections in accordance with international standard procedures. During the appearance inspection, weld quality and component assembly accuracy were checked one by one, confirming no cracks, deformation, or other defects. Paint thickness was measured using professional coating thickness gauges, with multi-point sampling showing all readings meeting the 50μm design requirement. Dimensional measurement focused on key parameters such as spreader opening width and lock head spacing, with errors controlled within ±2mm to ensure precise alignment. In the core lifting test, the spreader completed a 1.25x static load test (sustaining 50 tons for 10 minutes) without permanent structural deformation; subsequent dynamic load tests (3 cycles of lifting-translation-lowering under 50 tons) demonstrated rapid hydraulic system response, stable locking mechanisms, and no material spillage or component failure—fully verifying the spreader's safety and reliability under extreme working conditions.
