How many types of electric hydraulic grabs are there?

March 22, 2022

It is a kind of grab with its own motor, hydraulic pump and other hydraulic systems, can be connected to external power supply through the wire and cable to achieve electric operation, has high efficiency.


There are many common types of electric hydraulic grabs, Such as Electric hydraulic clamshell grab, Electric hydraulic orange peel grab, Electric hydraulic timber grabs, Electric hydraulic rectangular grabs and so on. Next, OUCO will introduce you to these types of electric hydraulic grabs!

5. Electro-hydraulic straw grab

Straw grab is a kind of material handling equipment specially developed for straw power plants, mainly for unloading, stacking storage and feeding of straw bales. This kind of grab works at a high level, and it is adapted to the needs of the power plant straw silo working environment which is wet, dusty, frequently used and uninterrupted.


6. Electro-hydraulic excavator grab

The hydraulic system of excavator grab comes from excavators and cranes. According to the shape, it can be divided into clamshell type and orange peel type, the clamshell excavator grab consists of two buckets, and the orange peel excavator grab consists of three or more buckets. The excavator grab itself is equipped with an opening and closing structure and is generally driven by hydraulic cylinders, so the grab consisting of multiple bucket is also called a hydraulic bucket.

The hydraulic excavator grab has a simple structure, Safe and reliable operation. It is suitable for construction foundation pit excavation, Used for deep pit excavation on construction sites, excavator grabs can be loaded with mud, sand, broken coal blocks, irregular gravel, etc. In addition, it is more flexible and can be used in uneven or restricted spaces.


The above are several common electric hydraulic grabs introduction, there are some small categories will not be introduced here, the next article, we will introduce you a more special, affordable hydraulic grab - remote control grabs. If you are interested, stay tuned with us!
