Shandong Highling Dredge Co., Ltd. was established in 1992. Its branch is Shandong Haiyang Ore Machinery Manufacturing Co., Ltd. Over years of development, the company has been the largest production center of cutter suction dredgers, sand mining machinery and gold dredging machinery. To enlarge production, we have built Highling Dredge Machinery Co., Ltd. in Coastal Developing Zone in Weifang city, Shandong Province. With an area of more than two hundred acres, It owns blanking workshop, gold panning machinery processing workshop, machining workshop, anti-corrosion workshop, general assembly workshop, product debugging and testing center before ex-factory.

Our dredger will be dismantle for different parts and then shipping to the port.

The kind structrue is convenient for transport in the working process if in

different working sites.

Many models of diesel engine can be selected on dredger, which as Cummins engine or DEUTZ MAN-MWM engine or Caterpillar world class level engine, there is after-sale services all over the world for any brand engine, which it is easily for maintaining and repairing, spares are cheap can be selected with dredger.

Usually, There are steel pipelines and PE pipelines, customers can buy them from us or themselves. If customers have special requirement, the pipeline and the floater can be customer made by suppliers. In packaging, pipelines and floaters are put into 40" high container for shipping.

Generally, customers need to buy more pipelines. Thats because pipelines can be bend for time saving.

Deck crane for cutter suction dredger:

The deck crane, installed beside the sand pump, is a kind of lifting equipment with cantilever and mainly used as a tool when repairing the sand pump and replacing the wearing parts.

Dredging pump

Dredging pump is one of the most important parts on cutter suction dredger, mainly applied to suction the mud, sand or other liquid mixtures from river or sea beds and send them to the barges or the land.

The dredge pump is driven by the main diesel engine through the reducing gear box.

Cutter head with replaceable teeth

Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.

Swing Hydraulic Winches

For ladder side pull two winches are provided on the front of the main pontoon mounted on a stiffened foundation. The winch is hydraulically driven through a reduction gearbox build in the winch structure. The winch has a disc brake that is automatically activated in case of pressure drop. The winch is operated from the control cabin and has variable speed.

Assembly & Staff Training

Our two experienced engineers will arrive at the construction site to guide, teach and training your staff to debug and operate the dredger until they can operate the machine skillfully by themselves.
