3. Dredger description
Sand suction transporter is made up of sand suction transporter and small sand dredger. It can not only dredge sand in the river, but also can load sand to the river shore.
This dredger can unload sand into river and then the small shore sand suction dredger sucks sand into river shore, or it has a set of pump, so the sand will be discharged to river shore by the pump.

Packaging & Shipping
1. Packaging & Transportation
The dredgers are detachable, so it is dismantled into one or two containers. Usually our products are shipped from Qingdao Port or Guangzhou to all over the world.
Because the transporter is very large, especially larger than 45cbm, it is difficult to load by containers. So we usually build the transporters in the working site according to the customers' requirement. Or we can build it in our workshop, but shipped in bulk.
2. Installation
Our experienced installers will arrive at the working site to guideand trainyour staff to debug and operate the dredger until they can operate skillfullyby themselves.

2. Additonal information
1). The main generator set adopts the supercharged, inter-cooled marine engines whose model is KTA19-G4(M)from CCEC company, rated speed 1800r/min,rated power 507kw. The diesel engine drives 500kw, 440V, 60Hz motors, generator capacity is set as 450kw.Generator drives the 315kw underwater pump motor, 55kw electric cutter head and 22kw hydraulic pump aggregate through frequency converter.
2). Cutter head transmission device
The electric cutter head transmission device is equipped on the bridge, when the bridge down angle 50°,the dredging depth is 8m.The bridge structure is truss structure type, the bridge is hung by the bow crane through the steel wire rope, and driven by one set 60kN hydraulic winch.
There are two sets 50KN sway hydraulic winch with rope speed 0~20m/min on the bridge. The wirerope of the sway winch rolled out of the sheaves which set in the front of the bridge and extend to two sides of the dredger, under the cooperation of two sets sway winches, with the spud carrier as the center, to make the dredger or so sideslip.
In the operation, the generator provides power through frequency converter (Brand: Schneider),controlling the motor speed according to the dredging condition to meet different soil conditions.
Shaft power 55kw
Output shaft torque 22KN.m
Output shaft speed 0~30r/min
Frequency conversion submersible motor 55kw(750-975 rpm)
Cutter head type Crown
Inner diameter 970mm
Cutter head height 750mm
Quantity of blades 5pcs
Prong max outer diameter 1370mm
3).Pump
The dredger equips with only one set underwater pump which is the new type pump refers to the IHC pump. Its advantages include: high efficient, wear-resisting, good cavitation performance. In order to improve the injection capacity and mud concentration, the underwater pump is driven by motor directly. The motor is B4J355LC6 water-cooled type from MarelliMotoriItaly which is set in sealed cabin of the cutter ladder.
In the operation, the generator provides power through frequency converter (Brand: Schneider),controlling the motor speed according to the dredging condition to meet different soil conditions.
Water overflow 1200m3/h
Lift 60m
Speed 1000r/min
Motor power 315kw
Motor speed 1000r/min
4) Positioning and Shifting device
4-1) Main spud system
Pole diameter 500mm
Pole length 13000mm
Stroke 2500mm
4-2) Auxiliary spud system
Pole diameter 500mm
Pole length 13000mm
The positioning and shifting device adopts spud carrier system and the other spud on the left pontoon to make the dredger location and shift.
The promotion and demotion of the spud is driven each by one plunger cylinder, using the traverse pin to make it jacking and switching.
The main spud system is the spud carrier with horizontal and vertical slider sets in the slotting of the stern, carrier stroke is 2500mm, carrier hydro-cylinder is piston cylinder, stroke is 2500mm. Pulling and penetrate spud alternative work is no need within the range. Carrier track and hull structure are all in one, track and slider face need machining. Workers can monitor the carrier stroke in the control cabin (with limit alarm), it is easy to control the displacement of the dredger.
5) Anchoring system
There are two sets anchoring devices on each side of the stem. The device constitutes with cathead, anchor davit socket, snatch block, stand column, leading sheave, anchor winch and so on.
The length of cathead is 9m, the maximum span outside board is 7.5m,the cathead can swing on the sides. Anchor-handing is controlled by 30kN hydraulic anchor winch, the rope speed is about 0~20m.
