冠诚挖泥船：
耙吸挖泥船

利用设在吸泥口前的泥耙进行松土，主要用于疏浚航道。它的中部设有开底泥舱，其容积表示船的大小，以立方米计。泥耙有单耙或双耙。单耙置于任一舷或船中部或尾中部；双耙分置于两舷。泥耙松土后，用泥泵将泥浆吸入泥舱。耙吸挖泥船可以自航，泥舱装满后，船驶至指定地点放抛泥浆，或采用高架边抛、溢流等方法抛泥。耙头、耙齿、泥泵衬板均用高锰钢制造，适合挖淤泥和砂粘土等，挖泥深度为4～24米,生产能力每小时约1000～12000立方米。船首中部装有横向推进器，便于转向掉头，航行动力为两台主机。绞吸挖泥船是利用吸泥口处可旋转的铰刀进行松土，主要用于挖填港池。一般为非自航式。为便于工地调迁，有的装有航行主机。甲板上装有绞机4～6台用于移位，并装有起落铰刀架，架上有铰刀轴，轴端装开式或闭式铰刀片，镶有锰钢齿。挖泥时将铰刀架一端放至指定深度进行挖泥，有的在铰刀处装有小型斗轮旋转挖泥，叫做斗轮式。挖起的泥用泥泵沿吸泥管吸入，再通过排泥管排至指定地点。排泥管有浮动式水上排泥管和陆上排泥管，前者可随船移动。排泥距离可达5000米。作业时移动船位除靠绞机外，还可用船尾的两根定位长桩，互换交替进行作业，使水下挖泥面平整。铰吸挖泥船适于挖粘土和砂泥，挖泥深度为4～30米,生产能力每小时约40～4000立方米。

Crown-dredger:
Trailing suction hopper dredger

Use suction port located in front of the mud rake scarification, mainly for dredging waterways. It's the middle of the sediment compartment has opened, the volume represents the size of the ship, in cubic meter. Mud rake rake single or double rake. Single rake placed either side of the middle or the end of the middle or boat; double rake divided into two sides. After scarification rake mud, mud pump mud suction hopper. You can self-propelled trailing suction hopper dredger, hopper filled after the ship reaching the designated place to put throw mud, or the use of elevated side throw, throw mud overflow and other methods. Rake head, fingers, mud pump liners are made of high-manganese steel manufacturing, for digging clay, silt and sand dredging depth of 4 to 24 meters, the production capacity of about 1,000 to 12,000 cubic meters per hour. Central air-transverse bow thrusters, easy steering turn, sail power for the two hosts. Cutter suction dredger is the use of suction mouth rotatable reamer scarification, mainly for cut and fill basin. General non-self-propelled. In order to facilitate the site to relocate, some equipped with navigation host. Mounted on the deck twister 4-6 sets for the shift, and is equipped with landing hinge holder, shelves have reamer shaft, shaft mounted hinge blade open or closed, manganese steel inlaid teeth. The hinge turret put an end to a specified depth when dredging dredging, some equipped with a small bucket wheel excavators at the reamer rotating at, called bucket wheel. Wedge of mud with mud pump suction along suction tube, and then discharged to the designated place through mud tubes. Mud tubes floating above water and mud tubes onshore mud tubes, the former can move onboard. Mud distance of up to 5000 meters. In addition to moving the ship's position by the twister, but also with two aft positioning long pile, when the job is a job swap alternately make underwater dredging planing. Hinge suitable suction dredger digging clay and sand and mud, dredging depth of 4 to 30 meters, the production capacity of about 40 to 4000 cubic meters per hour.]
