Producer
Rainbow Industries (RIC)
Chinese crane manufacturer and the fastest-growing RTG supplier. In July 2022, Kalmar transferred all its heavy crane intellectual property (RTG, RMG, STS, ASC) to Rainbow at its Taicang, Jiangsu facility. Rainbow now holds the IP behind all Kalmar-branded heavy cranes globally. Currently holds 21.84% of global RTG forward order book (2025+ delivery) — second largest in the world. TTM revenue (to Sep 2025): $1.08B. Terminals running legacy "Kalmar" RTGs now depend on a Chinese company for IP, spare parts, and software.

Did you know2022
In July 2022, Cargotec's Kalmar division transferred all heavy crane intellectual property — RTG, RMG, STS, and ASC crane designs, engineering drawings, software, and manufacturing knowledge — to Jiangsu Rainbow Heavy Industries, a Chinese company. Every port terminal in the world currently operating a crane branded "Kalmar" — whether it was purchased under Cargotec/Kalmar branding — now depends on a Chinese company for spare parts sourcing, software updates, and engineering support for that equipment. Port operators who believed they were operating Finnish crane technology are now operationally dependent on Rainbow (China) for the life cycle of that equipment. This IP transfer is the RTG equivalent of the ZPMC STS crane dominance story: two separate mechanisms through which Chinese entities have captured control of the global container crane supply chain.

ZPMC (the Chinese STS crane dominant, owned by China Communications Construction Company/SASAC) controls ~70-80% of STS cranes at US ports, while Rainbow now holds the IP for the Kalmar-branded RTG crane fleet deployed globally and holds 21.84% of the global RTG forward order book — making it the #2 RTG supplier worldwide. Combined, two Chinese state-affiliated manufacturers effectively control the global container crane supply chain across both ship-to-shore (ZPMC) and container yard stacking (ZPMC + Rainbow/Kalmar-IP) equipment segments. The 2024 congressional investigation found unexplained cellular modems in ZPMC cranes; Rainbow's IP capture of the Kalmar portfolio creates a parallel dependency for RTG-operated terminals — both the STS and RTG layers of the container port infrastructure cycle now run through Chinese entities.

In July 2022, Kalmar (then part of Cargotec) transferred all heavy crane intellectual property — covering RTG, RMG, STS, and ASC crane designs — to Rainbow Industries (RIC) at Taicang, Jiangsu, China. Kalmar took EUR 36 million in restructuring charges and transferred ~40 employees. This eliminated the last major European-IP RTG producer with Chinese manufacturing. Terminals globally now running "Kalmar" RTGs are operating on what is now Chinese-owned intellectual property, and future spare parts, software updates, and engineering support flow through Rainbow Industries — a shift unknown to most port operators who associate "Kalmar" with Finnish engineering.
Kalmar Global ↗Origin2022
Jiangsu Rainbow Heavy Industries (SZ:002419) was founded in Nantong, Jiangsu Province as a Chinese port equipment manufacturer and grew rapidly through competitive pricing in the RTG crane market. The defining event: in July 2022, Kalmar (the Finnish crane brand owned by Cargotec, one of the world's largest crane manufacturers and a legacy European crane brand) transferred ALL of its heavy crane intellectual property — covering RTG, RMG, STS, and ASC crane designs — to Rainbow at Kalmar's former manufacturing facility in Taicang, Jiangsu. Kalmar retained its brand name for marketing but transferred the underlying engineering IP, technical drawings, software, and manufacturing know-how. Rainbow simultaneously took over production at the Taicang site. TTM revenue reached $1.08B by September 2025, making Rainbow the fastest-growing heavy crane manufacturer in the world.
Rainbow Industries ↗Capacity2025
Rainbow Heavy Industries holds 21.84% of the global RTG forward order book for 2025+ delivery — the second-largest share in the world and the fastest-growing position in the market. At $1.08B TTM revenue (to September 2025), Rainbow has grown to become one of the top five global crane manufacturers by revenue in approximately a decade of serious market expansion. The company manufactures at its Taicang, Jiangsu facility — the former Kalmar manufacturing site acquired in the IP transfer — giving it both the physical infrastructure and the engineering knowledge base of a legacy European crane manufacturer at Chinese cost structure. The combination of Kalmar IP, Kalmar's engineering team knowledge, and Chinese manufacturing economics is the structural explanation for Rainbow's rapid RTG market share capture.
