SGS - Certified Hydraulic Rotary Excavator Stone Grapple For Hard Stone

Description:

Stone grapple is one excavator working device, stone grapple is designed for a specific job requirements excavator independent design, development, manufacture, one excavator working device accessories; stone grapple is divided into: mechanical stone gapple, and rotary stone grapple; mechanical excavator grapple the stone without modification piping and hydraulic systems can be used (a low-cost type); require modification of rotary excavator grab stoneware pipes and hydraulic systems to meet the needs of a 360-degree rotation (convenience, practical, cost-based).

Advantages of Stone grab

1. grasper unit body with a special wear-resistant manganese steel production (high elasticity, resistance to abrasion)

2. using the built-in safety valve to prevent cylinder naturally out arm

3. large-capacity fuel tank design, increasing the strength of equipment grab

4. 360 degree rotating super adjustability, and can meet the needs of the special conditions of

5. different types of products in the lightest weight, the maximum width of open files

6. uses a rotating gear mode, to further improve the durability of the product

7. The key components used in all imported from Europe, will play better results in weight and poor working conditions, higher excellence, efficiency!

Type:

1. Mechanical stone grapple;

2. 360 ° rotary hydraulic stone grapple;

3. Non-rotating hydraulic stone grapple.

Stone grapple’s installation:

1. mechanical excavator grab stone: The excavator bucket cylinder push, do not add another hydraulic block and piping;

2. 360 ° rotating hydraulic excavator grab stone: you need to add two sets of hydraulic valve block and piping on the excavator to control;

3. Non-rotating hydraulic excavator grab stone: you need to add on a hydraulic excavator valve block and piping to control.

We have the excavator stone grapple used for follow types:
