What Is an Excavator Grapple?

Excavator grabs refer to grabs that are used in conjunction with excavators, and are generally hydraulic grabs driven by hydraulic cylinders. Excavator grabs rely on the opening and closing of two left and right combined buckets or multiple jaws to lift and unload the spreader. The grab consisting of multiple jaws is also called a claw.

Excavator grabs can be divided into shell grabs and orange flap grabs by shape. The former consists of two complete bucket-shaped members and the latter consists of three or more jaw plates. The excavator grab is equipped with an opening and closing structure, which is generally driven by a hydraulic oil cylinder, so a grab consisting of multiple jaws is also called a hydraulic claw.

The excavator grab can be divided into two types: rotary and non-swivel according to the operating characteristics. The grab without bucket uses the oil circuit of the bucket cylinder of the excavator without adding additional hydraulic valve blocks and pipelines. To add a set of hydraulic valve block and pipeline to control.

Application of hydraulic grab for excavator:

1. Foundation pit excavation, deep pit excavation, and loading of mud, sand, coal, and gravel on the building foundation.

2. It is especially suitable for digging and loading on one side of trench or restricted space.

3. It is suitable for loading and unloading ships, trains and automobiles.

4. It is suitable for bulk materials such as coal, ore powder, sand and stone, scrap steel, round wood, straw, reed, moso bamboo.

Excavator grab is a kind of hydraulic structural products. It consists of hydraulic cylinder, bucket (jaw plate), connecting column, ear plate, ear cover, bucket teeth, tooth seat and other spare parts, so welding is the key to hydraulic grab. Manufacturing process, welding quality directly affects the structural strength and service life of the hydraulic grab. In addition, the hydraulic cylinder is also the most critical driving component.

Excavator grabs are special industry equipment accessories. Special equipment is required to perform operations efficiently and with high quality, such as: CNC plasma cutting machines, bevel milling machines, plate rolling machines, welding positioners, boring machines, hydraulic test benches Wait.
