Kinocranes, a worldwide trusted supplier of smart lifting equipment, has finished delivering two tailor-made 1 ton small gantry crane to a professional stainless steel manufacturing plant in Japan back in June 2025.This project proves our capability to meet strict technical standards for Japan’s industrial sector. Furthermore, our precision lifting equipment delivers stable load performance alongside flexible mobility, perfectly fitting modern metal processing workshops.
Project Background and Requirements
The client operates high-precision metal trading and stainless steel production in Japan, and they needed a lifting solution to fill the gap between bulky overhead cranes and manual handling. Specifically, their production workflow demanded frequent transportation of semi-finished stainless steel parts across different workshop areas.
The primary challenges were twofold: first, the need for a structure that could operate within the tight spatial constraints typical of Japanese urban industrial facilities; and second, the requirement for a power system fully compatible with the localized 220V 60Hz grid. Kinocranes provided a tailored solution that integrated high-strength structural integrity with low-profile engineering to maximize the available workspace.
Technical Specifications
To meet the rigorous demands of the stainless steel industry, the following technical parameters were finalized for the two-set delivery:
System Type: Semi-Portable Electric Small Gantry Crane
Rated Lifting Capacity: 1,000 kg (1 Ton)
Operational Span: 4 meters (Engineered for aisle clearance)
Safety Rating: Designed for high-frequency industrial cycles
Key Engineering Features
Advanced Lightweight Structural Design: This 1-ton frame adopts high-grade steel featuring optimized strength-to-weight performance. As a result, workers are able to move the crane effortlessly. Moreover, it fits stainless steel production layouts that require frequent adjustments, thus eliminating expensive permanent building renovations.
Precision 4m Span for Multi-Zone Utility: The 4-meter span was strategically engineered to allow the crane to straddle standard production workbenches and workshop aisles. This ensures that the two sets can work in tandem or independently to transport metal components across different stages of processing—from cutting to polishing—without interrupting floor-level traffic.
3.5m Height Optimized for Ergonomics and Clearance: By maintaining a 3.5m lifting height, the system provides ample vertical room for hoisting long stainless steel bars and sheets over existing machinery, while ensuring the top of the crane remains well below factory ceiling obstructions and HVAC systems common in Japanese facilities.
Electric Traveling Chain Hoist with Precision Inching: Unlike wire rope hoists, the electric chain hoist used here offers superior stability and minimal swaying. This is critical for metal trading, where the surface finish of stainless steel is paramount; precision "inching" capabilities allow for the gentle placement of loads, preventing surface marring and material waste.
Industrial-Grade Remote Control Interface: To enhance operator safety, each crane is equipped with a wireless remote control. This allows the operator to maintain the best vantage point while moving heavy components, eliminating the blind spots associated with pendant controls and ensuring higher safety standards in the high-traffic environment of a stainless steel factory.
Localized 220V 60Hz Power Engineering: Recognizing the unique power requirements in Japan, Kinocranes’ electrical engineers configured the entire control cabinet and motors for 220V 60Hz 3P. This guarantees stable torque performance and prevents motor overheating, ensuring the long-term reliability of the electronic components under continuous industrial use.
Quality Assurance and Standards Compliance
Quality is the cornerstone of Kinocranes’ reputation. This 1 ton small gantry crane project underwent a series of rigorous factory acceptance tests (FAT), including 125% static load testing and 110% dynamic load testing. The manufacturing process adheres to international ISO standards and aligns with the safety expectations of the Japanese market. Every weld and electrical connection was inspected to ensure durability in the corrosive-resistant yet demanding environments found in stainless steel production facilities.
