，zai滑輪組的作用下，滑移座上升帶動下承梁漸漸向上，同時帶動顎瓣閉合
，並抓取物料。

When grab is open, slip block is touching the up beam but it is totally separate with the down beam.Electromagnetic exchange valve is closed at this time. The piston rod of the cylinder and then slip block, and cylinder is firmly jointed together with the down beam, sothe piston rod of the cylinder is fully extended at this time.When the grab is to grab the bulk, crane sling declines and the cylinder is pulled back as the piston rod of the cylinder can be in directed movement，and then the slip block declines.After the piston rod of the cylinder is in complete contraction, slip blocks are totally fallen down.Then the sling of the crane is raised to lead the slip block up. As the electromagnetic valve of cylinder is always closed and the rod end chamber of the cylinder is locked, with the pulley, slip block rises to drive the down beam to up,at the same time; the jaws are closedrod end chamberand grip materials.

When open grab,press the switch of the remote control tran**itter. Electromagnetic directional valve of the hydraulic system is fully energized to commutate. Therod end chamberof the cylinder offloads.Piston rod of the cylinder is pulled out by the slip block and down beam, and slip block is separated with down beam, so the grab is gradually opened.

 紫石*先進的遙控抓鬥又可變成單繩手拉抓鬥

一、技術原理  
  由於科學技術的高速發展，單繩抓鬥的開閉裝置出現多個品種
，如：隻有一種裝置的遙控抓鬥、電動液壓抓鬥、電動馬達抓鬥
、手拉單繩抓鬥、碰地打開單繩抓鬥（落地打開單繩抓鬥）等，但是每個抓鬥隻采取一種開閉裝置。若開閉裝置出現了故障，一時又缺乏零部件或維修人員，抓鬥隻能停止作業；再一個抓鬥遠離維修**，單(dan)繩(sheng)船(chuan)用(yong)抓(zhua)鬥(dou)隨(sui)船(chuan)作(zuo)業(ye)，一(yi)旦(dan)開(kai)閉(bi)裝(zhuang)置(zhi)出(chu)現(xian)故(gu)障(zhang)，隻(zhi)能(neng)棄(qi)而(er)不(bu)用(yong)，影(ying)響(xiang)工(gong)作(zuo)進(jin)度(du)和(he)降(jiang)低(di)經(jing)濟(ji)效(xiao)益(yi)。同(tong)時(shi)，單(dan)繩(sheng)抓(zhua)鬥(dou)遙(yao)控(kong)開(kai)閉(bi)裝(zhuang)置(zhi)雖(sui)已(yi)試(shi)製(zhi)成(cheng)功(gong)

，通過抓鬥的主油缸、液壓夾杆鍥形重塊或拉杆、手拉夾杆鍥型重塊控製偏心板與斜壓板的離合，達到控製抓鬥開閉的效果。安裝該開閉裝置的散貨抓鬥能在空中任意位置卸貨。  
  二、使用優點 
  新型無線遙控散貨抓鬥具有以下優點 1.  zhezhongshezhinengyongyaokonghuoshoulaliangyongkaibizhuangzhikongzhidansuozhuadou，kuodalezhuadoudeshiyonggongneng，shizhuadoudeshiyingxingzengqiang
，gongzuoxiaolvtigao。qieliangzhongbutongkaibizhuangzhinengqiaomiao、有機的結合，裝置結構簡單、可靠，使用方便。當一種啟閉裝置故障時，在很短的時間**能更換開閉裝置，可提高裝卸速度和裝卸效益，減少船舶停靠時間，縮短船舶運行周期。   2.  新型紫石遙控散貨抓鬥與普通單索散貨抓鬥相比
，不僅保持原有的功能，而且增加了無線遙控裝置。無線遙控開閉裝置能在 50m 的範圍內控製抓鬥自由操作，可提高裝卸速度 25%， 3.  新型紫石遙控散貨抓鬥與原無線遙控散貨抓鬥相比

，在原理上更科學
、結構上更可靠。減少維修成本和時間，提高裝卸效率。 4.  新型紫石散貨遙控抓鬥應用先進的無線遙控裝置，信號穩定，有利安全生產
，低噪聲，有利於環境保護。  
   三
、產品前景

   新型紫石遙控散貨抓鬥，前景廣闊，將會代替單繩手拉抓鬥或以前隻有一種裝置（遙控）的抓鬥，是目前世界上*先進、*耐用可靠、維修費用*低（因液壓係統是進口）且工作效率*高的一種新型遙控散貨抓鬥。
