Operation Rules Of Remote Control Grab

(1).When use the grab, the safety operation rules of the crane must be followed
(2).Wedge sets/Rope cramp should be checked before use, and their installation should be according to the technical requirements, if loose, please fasten in time. If the shackles deform, wedge sets crack, screws of the rope cramp damage, they should be changed.
(3).Empty grab test should be carried on--all the turning parts should be flexible, grabs' opening & closing should be accurate and smooth.
(4).To avoid damages to the grab, hit the materials/cranes/ship rails... in high speed is not allowed.
(5).The balancing stand on the transverse frame should turn smoothly, and the steel wire rope should swing freely & keep horizontal when the grab is working.
(6).The grab should be kept vertical when it is on the materials, which makes the transverse frame fall smoothly. To avoid causing large yawing force(this force will effect the resetting of the piston rod) to the piston rod by the transverse frame, for the big angle caused by grab's leaning.
(7). All the turning axis pins, rope guide devices and bearings of the pulley should be added lubricant oil.
- Add lubricant oil before working.
- Add lubricant oil once at least after 24 hours continuously working.
-Add lubricant oil after finishing working each time.
-When stop using, the grab should be washed cleanly, and materials in transverse frame & each turning part should be cleared away. The grab should be close if do not work in a long time. And all the joints should be added sufficient grease or lubricant oil.
(8).To achieves the max. loading, the grab should work in the state of complete opening. The limit plate must keep touch, if the grab cannot close smoothly, should stop closing, then open the grab again to check if there are big blocks of the materials.
(9).When change the batteries, to avoid the damage caused by loose, the fasteners must be fastened.
(10).When use the new grab, the screws should be checked for every few hours. If loose, please fasten them in time.
(11). When the grab need move/deliver, the piston rod should be extended completely.
