How to choose grab bucket?
According to the SWL of the crane: Since the grab work together with the crane, You can comprehend your needs based on this formula:
(The capacity of the grab bucket * Material Density to be grabbed) + Dead weight of the grab bucket < Lifting capacity (SWL) of the crane
According to the grabbed material: the grab bucket is used for loading and unloading various goods, and selecting the appropriate grab bucket according to the specific gravity of the grabbed material will greatly improve the work efficiency.
For example: Coal for light duty Clamshell Grab, Stone Material for heavy duty Clamshell Grab, Steel Scrap for light duty Orange Peel Grab

Classification by shape
Clamshell Grab Bucket – also known as Dual scoop grabs, generally consist double bucket, which is a very common kind of grab.
Orange Peel Grab Bucket (Cactus Grab) – Is named after its bucket body looks like a peeled orange. Generally, it can be designed with 4, 6 or 8 jaw, according to the needs of grabbing.
In addition, there are some special-shaped grabs, such as log grabs, rectangular grabs, scissor grabs, etc., which are specially designed for grabbing a specific material.
Classification according to the driving method
Electro-hydraulic Grab Bucket – Driven by hydraulic cylinders, with high grabbing efficiency, but need to be powered by external cables, generally requiring customers to wire and install cable reel on the crane.
Mechanical Grab Bucket – Has a simple structure, is cheap and durable, but has no opening and closing structure, and is driven by external force and connecting rods, so the grabbing efficiency is low.
There is also a special kind of grab, the wireless remote control grab, which is the most popular grab in the industry at present. The remote control grab is generally with double scoops, which does not require extra accessories and power supply. It is powered by a battery and can be recharged when the power is exhausted.
According to industry statistics, the biggest contributor to failure and damage is wear and abrasion. Among the wear parts, we can subdivide them into these types of wear conditions:
Wear of shafts and pins
Shaft vibration and friction due to incorrect installation or uneven load distribution
Failure to maintain and lubricate regularly
gland packing and bushing damage
Erosion of sand or sea water when working at sea
Abrasion of bucket cutting edge
The grabbed material is too hard
The cutting edge needs to penetrate into the material frequently
Improper operation, cutting edge touching the ground or ship cabin
The cutting edge wear and thinning caused by the unloading of the grab bucket
Wear of pulleys
Wear of pulley grooves due to long-term use
The wire rope rubs the pulley
Poor contact between pulley and wire rope
The material of the pulley itself is uneven
Improper installation of pulleys
Wear of Wire Ropes
When installing the wire rope, the deviation angle is too large, Causes friction between wire rope and pulley
The wire rope may vibrate during operation and deviate from the pulley groove
Non-compliant manipulation of grabs, Incorrect opening and closing, causing the wire rope to wear or even break
During the grabbing operation, the wire rope collides or rubs against the edge of the cabin
Rust or dirt adhered to the wire rope
Insufficient maintenance and lubrication of wire ropes
Friction caused by tilting of the grab when grabbing material
Yes, please be assured that all OUCO grabs have optimum wear resistance.
We commit to improving the service life of our grabs in two ways. On the one hand, we have improved the wear resistance of the pins and bushings. And on the other hand, we have improved the wear resistance of the bucket edges.
In addition, we use different wear-resistant materials and processing techniques according to the different wear parts of grab buckets, thus greatly improving the service life of the grabs and reducing maintenance costs.
The cutting edge and shell of the OUCO grab are made of Hardox 450/500 wear plate. This steel can protect the grab and prevent the material from being worn on the bucket. Of course, its price is slightly more expensive.
Alternatively, you can also choose NM450 steel plate produced in China, a high-strength wear-resistant steel plate that is cost-effective.
If your questions are still unanswered, please do not hesitate to contact our sales staff!
As a professional grab bucket manufacturer, we know that the grab will inevitably collide during the operation, resulting in deformation and cracks of the grab.
Therefore, in order to ensure that the grab is not easily deformed, we have simplified the structure of the grab, and the weight saved is used to strengthen the bucket body and struts.
Through this design, we have not only improved the grabbing and digging capacity of grabs but also the strength and rigidity of the grabs.
Grab head and through beam: Based on strength and durability, we carry out a compact design, so that this part is lighter.
Press rods and scoops: On the basis of sufficient strength, we have increased its collision resistance.
Scoops cutting edge: As a key part of the grab bucket body, damage to the cutting edge plate will leak materials and increase costs. Therefore, we use wear-resistant and thickened materials.
The above is our design philosophy, and we can also meet all your custom requirements.
Clamshell Grab is more suitable for materials with regular shape and small volume, such as grain, gravel, sawdust, fertilizers, etc.
Orange Peel Grab is more suitable for materials with slightly larger and irregular shapes, such as scraps, stones and rocks, garbage, aggregates, etc.
In addition, there are some special shape grab buckets, which are used for grabbing wood and straw or dredging, etc.
