What Richard King & Sons does

Richard King & Sons is the English-language brand associated with Hunan Yuxiang Traction Electric Co., Ltd. (湖南宇翔牵引电气有限公司), a Xiangtan, Hunan-based manufacturer of underground mining electric locomotives and rail transportation equipment with approximately 40 years of operating history. Its core products span battery-powered, overhead line, lithium battery, and variable frequency drive locomotives in 2.5 to 14-ton capacities, complemented by DC and AC traction motors (including the ZQ-21 series), lithium iron phosphate battery systems with battery management, mine carts, personnel carriers, and rock loading machines. Technical differentiation rests on self-developed chopper speed control, variable frequency drives, explosion-proof isolation design, dual motor traction, and an intelligent dispatch system for automated narrow-gauge locomotive management.

The company operates a factory-direct hardware sales model, quoting custom-configured units at a stated 30% price advantage versus branded alternatives, supported by a service network spanning 60+ regions across China and a 24-hour customer hotline. It serves 18,000+ domestic mining and rail transport enterprises and exports to 20+ countries, with named customers spanning coal mines, gold mines, fluorite mines, metal mines, and research institutions such as China University of Mining and Technology. Mandatory Coal Safety (煤安证) and Mining Safety (矿安证) certifications plus ISO9001 quality management underpin market access in the regulated Chinese mining equipment market, while partnerships with Xiangdian Heavy Equipment (former Xiangtan Electric Motor Factory), CRRC, and three Chinese universities support ongoing R&D in autonomous driving and locomotive reliability.
