Equip a Clamshell Grab, and Instantly Transform Your Excavator into a Bulk Cargo Handling Expert.

The Pain Point: Are Excavators Only for Digging? You’re Wasting 90% of Their Potential.
Many construction business owners and equipment rental providers harbor a common misconception: that an excavator is capable of doing nothing else beyond using a digging bucket or a hydraulic breaker.

In reality, simply by equipping your excavator with a Hydraulic Clamshell Grab, you can instantly transform it from a "digger" into a "handler." Whether it’s silt dredged from a riverbed, scrap steel at a recycling yard, or sand and coal unloaded at a port, this grab attachment can "bite down" with the precision of a clamshell, efficiently scooping up and handling materials.

The key advantage? No modifications to the excavator itself are required—it’s truly "plug-and-play."

 Connection Solutions: Two Hydraulic Circuits, Two Choices
From the very outset of its design, our clamshell grab was engineered with on-site operational convenience in mind. Specifically designed as a front-end attachment for excavators, it offers highly flexible connection options:

Solution 1: Connect to the Bucket Cylinder Lines (Install-and-Use)
Suitable Models: Any standard excavator.

Connection Method: Directly connect the grab’s hydraulic hoses in series or in parallel with the excavator’s existing bucket cylinder lines.

Advantages: Requires no additional hydraulic kits, offering the lowest cost option; utilizes the excavator’s original "curling" motion to control the opening and closing of the grab.

Ideal Scenarios: Temporary projects or operations with limited budgets.

Solution 2: Connect to the Breaker Lines (Professional & Efficient)
Suitable Models: Excavators that already have dedicated hydraulic lines for a breaker (also known as auxiliary valves or bi-directional circuits)—either pre-installed or retrofitted.

Connection Method: Utilizes the excavator’s existing breaker circuit—controlled via a foot pedal or joystick button—to independently drive the grab.

Advantages: Offers more independent and precise control without interfering with the movements of the boom and arm; features rapid response times, making it ideal for high-intensity, continuous operations.

Ideal Scenarios: Long-term, high-volume handling operations, such as at scrap metal yards or for unloading bulk cargo at docks.

Regardless of which solution you choose, we provide the necessary quick couplers and adapters to ensure that the attachment can be switched out in under 5 minutes.

Two Main Types: Non-Rotating vs. Rotating—Which One Should You Choose? Based on operational requirements, we offer two structural configurations for our hydraulic clamshell grabs:

Type 1: Non-Rotating Clamshell Grab (Economical and Durable)
Structure: The grab body is fixed rigidly to the mounting bracket and cannot rotate 360°.

Advantages: Simple structure, lightweight design, affordable price point, and an extremely low failure rate.

Ideal Applications: Scenarios where the excavator remains stationary and the material source is located in a single direction—for example, directly unloading sand from trucks, feeding hoppers, or clearing ditches.

In a Nutshell: If you prioritize cost-effectiveness and pure grabbing functionality, this is the choice for you.

Type 2: 360° Hydraulic Rotating Clamshell Grab (The Versatile Champion)
Structure: A hydraulic rotation motor assembly is integrated between the grab body and the mounting bracket.

Advantages:

Precise Positioning: No matter the angle at which the material is piled, the grab can be rotated to face it directly for efficient scooping.

Flexible Placement: During unloading, the grab's orientation can be adjusted to stack materials neatly or to precisely load them into narrow truck beds.

The Ultimate Tool for Tight Spaces: Enables efficient operation within narrow construction gaps, deep wells, and foundation pits without the need to frequently reposition the excavator.

Ideal Applications: Scrap metal recycling, waste sorting, pile foundation construction, deep foundation pit cleaning, and clearing the bottoms of ship holds at docks.

In a Nutshell: If you prioritize maximum flexibility and operational efficiency, the rotating model is your best choice.

Why Choose Our Clamshell Grabs?
1. A Truly "Native Excavator Attachment"
Our grabs serve as a direct replacement for the standard excavator bucket, utilizing the machine's existing hydraulic lines—either the breaker hammer circuit or the standard bucket circuit—eliminating the need for an external power pack.

Equipped with standard check valves to prevent the grab from suddenly opening in the event of a hydraulic hose rupture, thereby ensuring operational safety.

2. Wear-Resistant Materials, Engineered for Harsh Conditions
The grab jaws are constructed from high-strength, wear-resistant steel (such as Hardox or an equivalent grade), and the edges can be fitted with replaceable bucket teeth or wear plates.

All critical pins and shafts undergo heat treatment and are fitted with self-lubricating bushings to minimize daily maintenance requirements. 3. Exceptional Material Versatility
Two-Claw Type: Ideal for handling ore, scrap steel, and large concrete blocks.

Multi-Claw Type (Orange-Peel Style): Suitable for handling municipal waste, wood chips, sludge, and cobblestones.

Sealed Type: Designed for handling grain, chemical fertilizers, and fine sand, ensuring zero spillage.
If an excavator is limited to merely digging earth, it remains just an excavator. However, when equipped with a hydraulic clamshell grab, it transforms into a mobile bulk material handling station.

Our product range covers a full spectrum of clamshell grabs, suitable for excavators ranging from 2-ton micro-models to 50-ton heavy-duty machines. We offer two configuration options—non-rotating and 360° rotating—and provide a choice between two hydraulic connection schemes: utilizing the existing bucket circuit or a dedicated breaker/hammer circuit.
