What Donghae does

Donghae Machinery & Aviation Co., Ltd. (동해기계항공) is a privately held South Korean manufacturer, founded in 1981 and headquartered in Gongju, Chungcheongnam-do, specializing in small and medium-sized aerial work vehicles and truck-mounted hydraulic cranes. Its product portfolio is organized into four lines: standard aerial platforms (e.g., DHS 1500AP, 15M working height), KEPCO-spec insulated aerial platforms for live-line electrical work (e.g., DHT 210AS, 21.3M working height), the Sky series for outdoor advertising and landscaping featuring a Korea-first boom auto-folding system (DHS 200 SKY), and hydraulic cranes for heavy lifting (1,600kg to 6,000kg capacity). The underlying technology combines proprietary mechanical and electro-hydraulic subsystems developed in-house, including remote control systems, hydraulic winches, automatic bucket leveling, smart cushion interlocks, and Strenx 700 high-strength steel boom structures, protected by 20+ registered patents.

The company monetizes primarily through hardware sales of new and certified used aerial platforms and hydraulic cranes, with revenue anchored by enterprise accounts such as Korea Electric Power Corporation (KEPCO), KT Corporation, and the China Northeast Electric Power Bureau, plus high-volume distribution through the Electrical Construction Cooperative (17,000 member companies) and Information & Communications Technology Cooperative group purchasing programs. Supporting revenue streams include after-sales service and parts through 13 directly-owned nationwide branches and 4 authorized dealers, plus financing programs bundled with Hyundai Commercial and KB Kookmin Capital. Export sales to 25+ countries are executed via local distributors. Reported revenue was KRW 111.1 billion (approximately USD 84M) as of December 31, 2022, with 222 employees. The company operates a small adjacent aviation training subsidiary (Donghae Flight School) and a legacy DAMBI light helicopter program, while its core commercial focus remains specialty industrial vehicles. CEO Kim Yong-jin leads the company; JKL holds an equity stake acquired in 2016-2018.
