The grabs are manufactured from the highest possible quality steels, such as Dillidur 450, Hardox 450, Dillimax 690 and Weldox 700 or equally renowned brands. The clamshell grab's closing rope guide can be equipped with low friction cable guides, which guarantee a long life span of the closing cables. Standard equipped with low friction spherical bearings in the pivots, which combine a high load bearing figure with low friction opening and closing of the grab. At your request, we can offer centralized lubrication systems.
Features
1. Power Guarantee: The motor of Electro-Hydraulic Marine Grab is imported from ABB, USA;
2. High Efficiency Guarantee: The high pressure oil pump of Motor Grab is imported from Parker, USA;
3. High Stability Guarantee: The Hydraulic System and Seals of Electro-Hydraulic Clamshell Grab are adopted German Technology;
4. Product Technology Guarantee: The Cable Drum and Wire Rope Reel of Motor Hydraulic Marine Grab are adopt German Advanced Technology: Hydraulic coupling type machine. It can infinitely vary speed and match the pull pressure and lowering speed automatically, which can make the synchronization of speed and pull pressure, and avoid the breakage of cable drum or wire rope reel.
5. Handling of powder and fine bulk materials such as chemicals, fertilizer, grain, coal, coke, iron ore, sand, particle construction materials and smashed rocks etc.
6. Our Motor Grab has the plate which can change the grab volume. That is the grab can change its grab according to the different material dealing with, which is more convenience for customer's usage.

FAQ
1. Q:In the material, how should we choose and determine?
A:The selection of the material of the grab edge plate, generally speaking, is the use of high strength wear-resistant steel plate.
2. Q:Electric grab, its use in the process should pay attention to what aspects?
A:In use process, should pay attention to the wire rope and the important parts, because, if the improper use of words, then, the prone to breakage, so we must have enough attention.
3. Q:Which is an important way to improve service life?
A:The important way to improve the service life of the grab bucket is to improve the abrasion resistance of the grab pin and shaft sleeve, and to improve the abrasion resistance of the blade of the bucket body.
4. Q: The type of grab and its span size, whether will affect the grab price?
A:The type of grab, such as the hook or double hook, will affect the price of the grab, because the type is different, then the corresponding price is also different. As for the span of the grab, it is also one of the factors affecting the price of the grab, so it will certainly have an impact.
