A hydraulic excavator grapple is a powerful attachment used to pick, sort, load, and move materials such as rocks, logs, scrap metal, and demolition waste. It uses the excavator’s hydraulic system to control the jaws, giving operators better grip and positioning than many mechanical attachments. For contractors and equipment buyers, the right grapple can improve handling efficiency while reducing manual work. If you are looking for a reliable grapple for your excavator, YG can provide suitable configurations based on your machine and application.

Key Parameters to Check Before Buying an Excavator Grapple
Before ordering an excavator grapple, check the following specifications with your equipment supplier:
| Item/Model | Unit | YGO04A | YGO06A | YGO08A | YGO06B | YGO08B |
| No. of Jaw | piece | 4/5 | 4/5 | 4/5 | 4/5 | 4/5 |
| Suitable Excavator | ton | 6-9 | 10-17 | 18-25 | 10-17 | 18-25 |
| Weight | kg | 355/420 | 900/1000 | 1650/1900 | 850/1000 | 1700/1950 |
| Max Open Jaw | mm | 1200 | 1600 | 2050 | 1900 | 2500 |
| Height of Opened Grapple | mm | 1000 | 1500 | 1700 | 1550 | 2000 |
| Working Pressure | bar | 200 | 260 | 320 | 260 | 320 |
| Working Flow | lpm | 50-100 | 60-120 | 200-250 | 60-120 | 200-250 |
| Capacity | m3 | 0.3 | 0.4 | 0.8 | 0.5 | 1 |
One common purchasing mistake is selecting a grapple only according to excavator tonnage.
Two excavators with similar operating weights can have different hydraulic flow and pressure. Always provide the excavator model, hydraulic pressure, oil flow, pin dimensions, and application before confirming the order.

How Does a Hydraulic Excavator Grapple Work?
The working process is straightforward. Hydraulic oil from the excavator enters the grapple cylinder and creates pressure. The cylinder then moves the jaw mechanism, causing the tines to open or close around the material.
If the grapple has a hydraulic rotation system, the operator can also rotate the attachment to adjust the load position.
How does a hydraulic excavator grapple work?
A hydraulic excavator grapple uses hydraulic oil from the excavator to operate its cylinder. The cylinder opens and closes the tines around the material. A hydraulic rotation system can further improve positioning, allowing the operator to pick, move, sort, and place materials with greater control.
The important point is that grapple performance depends on the complete hydraulic system. Incorrect oil flow or pressure can reduce performance or increase component wear.
Orange Peel Grapple vs Standard Excavator Grapple
An orange peel grapple has several curved sections that open around bulk or irregular materials. Its design is different from a conventional grapple with two or more opposing jaws.
| Feature | Standard Grapple | Orange Peel Grapple |
| Main use | General material handling | Scrap and bulk material |
| Jaw design | Opposing tines | Multiple curved sections |
| Grip style | Direct gripping | Enveloping grip |
| Common materials | Logs, rocks, waste | Scrap metal and bulk waste |
| Typical users | Construction contractors | Recycling and scrap facilities |
An orange peel design can be useful when the material is loose and irregular. However, it is not automatically the best choice for every excavator.
Consider the material density, loading method, required capacity, working environment, and operating cycle before choosing the design.
How to Match a Grapple to Your Excavator
Correct matching is one of the most important steps in the purchasing process.
Start with your excavator operating weight, but do not stop there. Then check the hydraulic and mechanical connection requirements.
A practical selection process is:
- Confirm the excavator model and operating weight.
- Check auxiliary hydraulic pressure.
- Check available hydraulic oil flow.
- Measure pin diameter and mounting dimensions.
- Define the main material to be handled.
- Select the required opening width and capacity.
- Decide whether hydraulic rotation is necessary.
- Confirm quick coupler compatibility if required.
For example, a contractor handling demolition concrete may need a heavier structure and reinforced tines. A recycling company handling lighter scrap may benefit more from a wider opening and rotating configuration.
Do not select a grapple based on excavator tonnage alone.

Applications of Hydraulic Excavator Grapples
Hydraulic grapples are used across several industries because they can handle materials that are difficult to pick with conventional buckets.
Common applications include:
- Scrap metal handling in recycling yards
- Log and timber handling in forestry
- Rock and stone handling in construction
- Demolition and building-site cleanup
- Waste sorting and recycling
- Quarry operations
- Material loading and unloading
- Land clearing and site preparation
The same excavator can also use different attachments for different jobs. Buyers looking for a complete attachment package can explore YG’s wider range of excavator attachments.
YG Hydraulic Excavator Grapple Manufacturing and Customization
As a manufacturer, YG focuses on matching grapple configurations to different excavators and working conditions.
Depending on the project, buyers can discuss options such as:
- Different grapple sizes
- Different jaw and tine configurations
- Fixed or hydraulic rotation
- Customized mounting dimensions
- Hydraulic connection options
- OEM and ODM requirements
- Excavator-specific compatibility
For an accurate recommendation, send YG your excavator model, operating weight, hydraulic pressure, oil flow, material type, required opening width, and order quantity.
This information allows the grapple configuration to be selected based on actual working conditions rather than a general size chart.

Frequently Asked Questions About Hydraulic Excavator Grapples
What size excavator can use a hydraulic grapple?
The correct grapple size depends on more than excavator tonnage. Hydraulic pressure, oil flow, attachment weight, mounting dimensions, and the intended material should all be checked before purchase.
How much does a hydraulic excavator grapple cost?
The price depends on grapple size, steel specification, hydraulic rotation, cylinder configuration, mounting system, customization, and order quantity. For an accurate quotation, provide your excavator and application details.
Can YG customize a grapple for my excavator?
Yes. YG can discuss customized mounting dimensions, jaw configurations, hydraulic connections, and other requirements according to the excavator and application.
What is the difference between a rock grab and a standard grapple?
A rock grab is generally designed for heavier and more impact-intensive materials. It typically uses a stronger structure and reinforced components, while a standard grapple may be optimized for general handling such as logs, waste, or light construction materials.
Should I choose a rotating or fixed grapple?
Choose a rotating grapple when accurate load positioning and sorting are important. A fixed grapple can be a practical choice when the work mainly involves straightforward picking and loading and a simpler configuration is preferred.
