Did you know2024
A March 2024 joint investigation by the House Homeland Security Committee and House Select Committee on China found unexplained cellular modems installed on ZPMC (Shanghai Zhenhua Heavy Industries) crane components at multiple US ports. The modems were not specified in any equipment contracts, port officials could not determine their purpose, and they were connected to the cranes' Linux-based operating control systems — enabling potential remote data transmission. ZPMC had separately requested remote access to its US-deployed cranes. Under China's national security laws, ZPMC would be legally required to provide Chinese intelligence agencies any such access if requested. Because STS cranes log every container movement — including cargo identity, weight, origin, and ship assignment — a surveillance-capable crane is a real-time intelligence feed on US military logistics, weapons shipments, and sanctions evasion. ZPMC is a subsidiary of China Communications Construction Company, a SASAC state-owned enterprise. ~80% of STS cranes at major US container ports are ZPMC-made.

The US response to ZPMC crane security concerns directly elevated Mitsui E&S / PACECO as the primary beneficiary: Biden Executive Order 14116 (February 21, 2024) targeted Chinese-manufactured port cranes; a US Coast Guard Maritime Security Directive required cybersecurity risk management for all ZPMC cranes at US strategic seaports; 100% Section 301 tariffs on Chinese-made STS cranes were finalized; and the Maritime Supply Chain Security Act (Senate, June 2025) authorized federal grants for ZPMC replacement. PACECO — as the only Japan-US allied STS crane supplier with existing commercial relationships and US engineering infrastructure — is the structural beneficiary of every element of this policy package. Mitsui E&S simultaneously launched Vietnam production capacity (targeting 30 cranes/year) to capture the broader global 'non-Chinese crane' demand wave from ports worldwide seeking to reduce ZPMC exposure.

PACECO (Pacific Coast Engineering Company) was founded in 1922 in California and invented the container crane in 1958-1959 — ASME Engineering Landmark designation. After selling to Fruehauf Corporation in 1967, PACECO's crane technology was acquired by Mitsui Engineering & Shipbuilding (now Mitsui E&S) in February 1989, the same year US crane manufacturing ceased entirely. For 35 years, PACECO continued as a US-based engineering and commercial subsidiary of Mitsui E&S while all fabrication moved to Japan. In February 2024, the Biden White House specifically named Mitsui E&S and PACECO in its $20B+ port infrastructure initiative as the vehicle for restoring US crane manufacturing capability — announcing a PACECO + Brookfield partnership for a California final assembly facility, the first US crane production since 1989. The company that invented the container crane abandoned US manufacturing, then was chosen 35 years later as the national security answer to Chinese crane dominance.
