YONGGONG assembly hall

A material handler manufacturer since 1992

Henan Huanghai Heavy Equipment Manufacturing Co., Ltd. designs, fabricates, assembles and tests YONGGONG hydraulic material handlers in its own plant in Yongcheng, Henan.

Over three decades we have grown from a single manufacturing business into an enterprise that combines R&D, production, sales, service and engineering training for special loading and unloading machinery.
