ROPE GRAB
FOR CRANES WITH SUSPENSION- AND CLOSING ROPES
The rope grab is operated on a crane with two hoisting drums. These are the closing rope drum and the suspension rope drum. The grab
is hanging on the suspension rope. Opening and closing of the grab shells is done by the closing ropes and the integrated pulley block.
(Closing ropes are redirected multiple times through rope pulleys)
According to the quantity of closing and suspension ropes, there is a distinction between single-line, double-rope or four-rope grabs.
The rope grab gains the force for closing and gathering the material through its deadweight, the lever ratio and the reeving of the pulley
block.
MOTOR GRAB
FOR CRANES WITH SUSPENSION- AND CLOSING ROPES
The motor grab is operated on a crane with one or two suspension rope drums. It has its own hydraulic drive unit consisting of an electrical motor, a hydraulic pump and hydraulic components.
The crane provides the electrical power via an electrical lead, which may include control lines also. From the hydraulic drive, the motor grab gains the closing force. This force is transferred to the material through a convenient lever ratio in conjunction with the proper deadweight.
HYDRAULIC GRAB
FOR EXCAVATORS OR CRANES WITH A HYDRAULIC LEAD
The hydraulic grab does not have an own drive unit. The hydraulic drive from the excavator provides the power. It is directly connected to the suspension of the excavator and the hydraulic supply lines.
Similar to the Motor grab, the closing force is transferred to the material through a convenient lever ratio in conjunction with the proper deadweight. The only difference is that the hydraulic drive is not included in the grab. An additional way to transfer the force is the relatively rigid connection to the excavator.

배관내 흐르는 유체를 차단하는 Shut-off Valve가 Open 상태에서 Close를 하거나 Close 상태에서 Open 동작을 할때 순간적으로 Valve를 차단 또는 개방을 함으로써 발생되는 수격현상(水擊現狀, Water hammering) 때문에 소음과 진동이 발생하고 이로 인하여 배관의 손상이나 계장품 또는 펌프에 치명적인 영향을 초래하게 됩니다. 이를 방지하기 위하여 Pilot Cylinder를 동작시켜 Equalizing 기능을 행한후 Main Cylinder를 동작시켜 유로(수로)의 흐름을 원활하게 함으로써 밸브의 차단 또는 개방시 발생하는 "충격을 방지하는 밸브" 입니다.
