Product Description

Shanghai Enjue marine Motor-hydraulic Clamshell Grab bucket
It is a merging of the radio remote control technology into the single rope grab for handling of bulk materials. It is particularly designed for operation with single-hook crane and ship crane, with reliable performance and easy operation procedures.The grab could be open and unload materials from any position in the air.
American Welding Society,all important welds are carried out in accordance with welding procedures. After welding, a certain amount of NDT control is carried out. We especially set up hydraulic department to ensure smooth production and high quality, all structure design and distribution of hydraulic system are taken charge of hydraulic department. All hydraulic elements are imported international well-known brands in machinery industry. Material of scoop is Q345B, material of all axes is 42CrMosf, by tempering and grinding, lips's rigidity should be reach HRC50. Ensure 24-hour test, ensure the normal operation of grab, after delivery. our wire rope- fixed head, four flange bolt-lifting eye, four brace-support scoop. Only suitable for single hook crane,The grab could be open and unload materials from any position in the air.

Technics standard:
 
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
 
And the part like the hydraulic cylinder,the hydraulic valve and so on will select famous factory's manufacture.
 
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.
 
9.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.
