The Grab Specialist - Product information

8 The Single Line Radio Remote Control ìHook onî Clamshell Grab can simply be Hooked on to your crane with sufficient lifting capacity and height, without any acces- sories. It operates as follows: The unlocking system for opening the grab is operated by Radio Remote Control. The advantage of the Radio Remote Controlled operation is that you can open the grab in ìMid Airî and stop and start the opening of the grab several times. The grab is lowered on the bulk in opened position. The sliding block is in upper position, the sliding block must be lowered towards the lower block carrier. The sliding block moves over the hooks inside the lower block. The hooks move back and the locking lever falls between the hooks. Thus the hooks hold the sliding block on its place. While the sliding block moves upwards, and thus also the lower block carrier, the grab will close. For opening the grab, the grab must be lowered on the bulk (in closed position). By doing this, the hooks inside the lower block carrier will move backwards for a little, so that the locking lever will be free for release. With the help of a release mechanism inside the head block carrier, the loc- king lever will move out, while the hooks move to each other. The lower block carrier is then released and the grab will open itself.
