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 transmitter. 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
