A 30ft spreader, specially customized for a German client, has successfully completed a full range of inspections by BV, a leading global third-party testing and certification body, at MAXTECH's factory. All indicators met international standards, and the certification was smoothly obtained. This semi-automatic mechanical spreader, which will undergo final packaging and logistics preparations before being shipped to Europe, marks another milestone in MAXTECH's dedication to the customized spreader market.
Customized Design Breaking Conventions: Focusing on 30ft Special Needs
In the field of container spreaders, 20ft, 40ft, and 45ft have long been the mainstream standard specifications. As a special size, 30ft spreaders are rarely available as mature mass-produced products due to their niche application scenarios. The German client, in need of port automation upgrades, required a 30ft spreader compatible with specific container models, with clear requirements for both 12-ton lifting capacity and semi-automatic mechanical operation — a demand that perfectly aligns with MAXTECH's "flexible spreader system" concept developed in recent years.
To accurately match the client's operational scenarios, the R&D team made three key innovations during the design phase:
1. Size Adaptation Optimization: Through an adjustable guide plate design, the alignment error of the spreader under standard 30ft working conditions is controlled within ±30mm.
2. Semi-automatic Mechanical Structure: Adopting a mechanical locking control system, it retains the high reliability of traditional mechanical spreaders (no reliance on complex circuits).
3. Lightweight Material Application: The main frame is made of high-strength low-alloy steel (HSLA), reducing weight by 15% compared to spreaders of the same type. Combined with the 12-ton rated load design, it perfectly adapts to the existing small and medium-sized container at the client's on site.
Full BV Inspection Process: Quality Verification Under Strict Standards
As the third-party testing agency designated by the client, BV's inspection scope covers three core dimensions of the spreader: structural safety, functional integrity, and durability. The entire inspection process is recorded on video, with data uploaded to the global inspection database in real-time.
At the inspection site, the engineering team focused on completing the following key items:
1. Static Load Test: The semi-auto spreader's locking mechanism was loaded with 110% of the rated load (15.5 tons) for 10 minutes. Stress monitoring showed that the maximum deformation of the main frame was only 0.8mm, far below BV's specified threshold of 3mm.
2. Dynamic Fatigue Test: Simulating high-frequency operation scenarios at the port, 10 cycles of lifting (with 15.5-ton load) were conducted. The mechanical locking device opened and closed smoothly without jamming, and the electronic sensing response delay remained ≤0.5 seconds.
From Blueprint to Port: Full-Chain Support for Customized Services
The creation of this spreader not only represents the implementation of a technical solution but also demonstrates MAXTECH's full-process control capability for customized projects.
During the production phase, the factory adopted a "customized solution" flexible manufacturing model, with full traceability from raw material entry to finished product assembly.
Currently, the spreader has entered the final preparation stage before shipment and will be transported to the Port of Hamburg, Germany via the China-Europe Railway Express. According to the project leader, this order has led to the signing of intent for 2 more spreaders of the same specification, and port enterprises from the Netherlands, Belgium, and other countries have also consulted about the customization of 30ft spreaders.
