1.Q345B,42CrMo,.HARDOX400,HRC50..Material of scoop is Q345B, material of all axes is 42CrMo, by tempering and grinding. Material lips is HARDOX400,and the rigidity should be reach HRC50.O ,the part's Material according to drawing.
2.,,,,,.The holes of up beam,pole,low beam and scoops are bored by machine, it can ensure the concentric,detailed allowance error according to drawing request.
3..,160um.All steel will blasting shot before machining. After completion of the production deal with the surface coating, Thickness of coating greater than 160um.
4.,.,.The activities of nodes need to consider lubrication, the attention of the design, such as lubricating device should not be bump. Installation of hydraulic cylinders to be used in spherical joints, and have the lubrication.
5.,,.3.All important place should go to beveling,and welded joints carry on the loss less crack detection, and the grade of welded joints must reach first-level.
6.,.The hydraulic system
7.,,.,.The grab should act accurately, the operation is flexible, do not have the greatly sound. The double clamshell grab must design has the automatic balanced organization, causes grab double clamshell to opening or the closing time synchronization.
8.10mm,3mm.,.Whole dimension deviation of grab should less than 10mm, mostly install dimension deviation less than 3mm.If there are some special requests, machining according to drawing.
All the grabs are directly linked to the hooks of the cranes. When designed the grabs should match size. The grabs are connected with the hook of the cranes in links. The strength of the links can lift the 3 times weight in security (including the dead weight and the holding material weight).
10..The installation position of each vulnerable must be considered the replacement the conveniences
11.,"",,.Each grab must be painted related marking in conspicuous place, including "ENJUE"nameplate,the grab serial number , rating burthen and so on.
12..Other end mentioned technological requirement according to the Ministry of Communications related grab manufacture standard and enterprise standard execution.

,/ Work theory
When the grab is opening, the moving board is connecting with top roof beam, and separate with down roof beam, at the that time, the hydraulic circuit system is opening, and the piston of hydraulic vat was pulled out by moving board. when grab the goods, the hook of the crane go down, the moving board go down along the hydraulic vat with the piston of the cylinder, when the moving board touch the stroke switch on the down roof beam, the stroke switch stop the electromagnetism valve to stop the hydraulic oil . The hook of the crane goes up with moving board and down roof beam, to make the grab close.
Press the radio switch, send the message to the receiver, then the electromagnetism valve open the hydraulic circuit system, the hydraulic vat was extended because of the gravity of goods and down roof beam, the down roof beam was separated from moving board, to make the grab open , and the grab can do the next closing cycle.
