scrap grabber/petal-shaped

Grab bucket is to grab sand and all kinds of bulk goods can open and close the bucket. It is a kind of spreader which mainly relies on the opening and closing of the left and right two combined buckets or multiple jaw plates to grab and unload bulk materials.

Grab bucket by the left and right combination of two buckets or a number of jaws of the opening and closing of the grab and unloading of bulk materials spreader, by a number of jaws composed of the grab is also known as the grabbing claw.

Classification by shape

According to the shape can be divided into shell-shaped grapple and orange flap grapple, the former consists of two complete buckets, the latter consists of three or more than three jaws.

Classification according to driving mode

According to the driving mode can be divided into two categories: hydraulic grab and mechanical grab.

Hydraulic grapple itself is equipped with an opening and closing structure, generally driven by a hydraulic cylinder, composed of multiple jaws hydraulic grapple is also called hydraulic claw. Hydraulic grapple in the hydraulic class of specialized equipment is widely used, such as hydraulic excavators, hydraulic lifting tower.

Hydraulic grapple is a hydraulic structural components products, by the hydraulic cylinder, bucket (jaw), connecting column, bucket ear plate, bucket ear sets, bucket teeth, teeth seat and other spare parts, so the welding is the most critical production process of the hydraulic grapple, welding quality directly affects the structural strength and service life of the hydraulic grapple. In addition, the hydraulic cylinder is also the most critical driving parts.

Hydraulic grab belongs to the special industry equipment parts, need special equipment to high efficiency, high quality operation, such as: CNC plasma cutting machine, beveling and milling machine, plate rolling machine, welding displacement machine, boring machine, hydraulic test bench.

Excavator hydraulic grapple for rotary and non-rotary two kinds of grabs, without rotary grabs using excavator bucket cylinder oil circuit, without adding another hydraulic valve block and piping; with rotary grabs to add a set of hydraulic valves and piping to control.

Excavator special hydraulic grab applicable occasions:
1, the building foundation of the pit excavation, deep pit excavation and mud, sand, coal, gravel loading.
2、Specially suitable for digging and loading on the side of ditch or restricted space.
3、It is suitable for loading and unloading of ships, trains and automobiles.
