DN1000 Bow coupling installation--------- The bow coupling installation mainly consists of a welded steel frame, which is mounted on the fore threstle of the ship and a hydraulic hoisting winch. The steel frame contains a hydraulically operated click-in ball joint, dredge line bend, uppper roll for the hoisting wire and optionally a rainbow nozzle. The unit is equipped with an operating panel and a hydraulic control block. The coupling procedure is easy: connect the floating pipe line to the hoisting wire, hoist into the click-in ball joint and close the click-in. The hydraulic control block will adapt automatically to the increasing hoisting load and will prevent the male part from being pulled into the click-in ball joint too fast.

We are offering dredger spud (ccsd36 )--------- •high quality steel made. •simple to assemble and disassemble. •longer wear life. •easy maintenance. •can be adjusted precisely. •easy maintenance. •any size is available. we design and delivers spuds in all sizes. The spuds' design forms an optimum between diameter, wall thickness and weight. The construction is of rolled steel pipe pieces with varying wall thickness, which are welded together with full pen welds. our spuds are fitted with pin holes for tilting as well as to secure the spud when it is not in use. The lower point is made of solid steel to ensure sufficient strength during ground penetration. When the spud is hoisted, water may escape through two holes above the lower point. On top, a hoisting eye allows for a crane to replace the spud easily. Standard spuds are made of grade a steel, but it is possible to order other material. We can provide a wide range of dredge spuds and any other marine spuds according to the the clients' any requests.

We are offering 55kw-4500kw cutter ladder for dredger--- the huaxia cutter ladder front parts are of a pipe or a box-type rigid design, complete with the cutter drive motor, cutter shaft, cutter shaft bearing and side wire swivel blocks. The unit can simply be mounted to the ladder of the dredge, connect hydraulics, greasing and flushing water and is then ready for use. The unit's extra sturdy design ensures a long lifetime. the high-efficiency slow running hydraulic motor drives the cutter shaft and cutter directly. The high starting torque of the motor helps to prevent the cutter from getting stuck. the cutter ladder front part is fitted with a cone in order to get an optimal flow of solids into the suction mouth. The suction mouth is also designed for this purpose. the water-lubricated rubber cutter shaft radial bearing has a long life time and is practically maintenance-free. In case the bearing needs to be replaced, it can be easily accessed from the front of the shaft. The axial (thrust) roller bearing is fitted in an oil chamber. for easy removal of the cutter head, the ladder front piece is fitted with an eye to lock the cutter and unscrew it by reversing the hydraulic motor. In case this does not suffice, the assembly also has a ‘flame cut ring. After cutting away this ring, the cutter head will be loosened on the thread of the shaft.

Pt-800 heavy duty drag head for tshd dredger------ benefits : • optimal draghead-bottom contact • effective bottom loosening • minimal resistance to flow • reduced blockages • optimally wear protected • designed for easy maintenance • fenders protect ship's hull the draghead of a trailing suction hopper dredger represents the first mechanical contact with bottom material, so its design, quality and sturdiness are critical in dredging and alluvial mining tasks. We have invested many years of practical experience and testing to create optimal draghead solutions for extracting the maximum of bottom soil at minimum time and cost, and continues to do so. the heavy duty dragheads offer a combination of high excavation capabilities for loosening the soil and optimised hydraulic properties for mixture transportation. High mixture concentrations are possible in many kinds of soil. The dragheads are welded constructions made of structural steel. Cutting teeth of abrasion resistant cast steel and jet water nozzles are arranged over the whole width of the visor.
