Company Profile & Manufacturing Scope

Who we are, what we build in-house, and what we source from named brand partners

WanRun Intelligent Equipment Co., Ltd. builds dredging, sand-mining and waterway-cleaning vessels in Mihe Town Industrial Park, Qingzhou, Shandong — one of China's main dredger manufacturing clusters. Our catalog runs to 104 models across 10+ series: cutter suction dredgers from 6 to 24 inch up to the 450 type, trailing suction hopper dredgers, bucket wheel dredgers, the Water King multifunctional amphibious work vessel, crawler amphibious excavators, aquatic plant and trash-skimmer cleaning boats, and jet, water-jet and bucket chain sand dredgers.

We are honest about where our boundaries are. In-house, we cut, form and weld hull sections and structural steel, assemble dredging pumps, ladders and winch systems, blast and paint every unit, and hold dock tests — pump output, vacuum, winch travel and full-machine trials — before shipment, with customer or third-party survey always welcome.

Major components such as dredging pumps, engines and hydraulic power packs are purchased from named brand suppliers, and every supplier is listed on your machine's build sheet. We prefer to tell buyers plainly: we know exactly what we build and what we source, and we put both in writing.
