360 Degree Rotating Hydraulic Clamshell Bucket for 20-30 Ton Excavator fits CAT 320 Komatsu PC200 Deep Well Digging Grab

Maximize Your Productivity with HWX Jinan Changhao Hydraulic Rotating Clamshell Buckets
In the demanding worlds of deep excavation, river dredging, and bulk material handling, efficiency isn’t just a goal—it’s a necessity. The HWX Jinan Changhao Hydraulic Clamshell Bucket is engineered to transform your excavator into a precision-driven material handling powerhouse.

1. Precision Engineering for Challenging Environments
Our clamshell buckets are designed with a focus on durability and performance. Constructed from high-strength Q355B steel with critical wear zones reinforced by NM400 wear plates, these attachments are built to withstand the abrasive nature of sand, silt, and rocky debris. Whether you are operating at a busy logistics port or cleaning a sediment-filled urban canal, the HWX grab ensures zero downtime.

All the clamshell buckets shown in the images were manufactured by us.

2. 360° Rotating Advantage: The Ultimate “Wrist” for Your Machine
Why limit your machine’s reach? Our 360-degree infinite rotation model features a high-torque hydraulic motor that allows for precise positioning of the bucket. This is a game-changer for:

Narrow Shaft Excavation: Perfect for digging foundation pits in crowded city centers where space is limited.
Port & Logistics: Speed up the loading and unloading of coal, grain, and gravel from trucks and ships.
River Dredging: Navigate around bridge pylons and underwater obstacles with surgical precision.
3. High Closing Force & Leak-Proof Design
Equipped with dual reinforced hydraulic cylinders, the HWX clamshell bucket provides massive closing force to ensure a full bucket every cycle. We prioritize reliability, which is why we standardize with high quality seal kits. This ensures leak-proof performance and stable pressure, even during deep underwater dredging projects.

4. Versatile Solutions for Every Fleet
At HWX Jinan Changhao, we understand that no two projects are the same. We offer a full range of capacities from 0.2m³ to 3.0m³, compatible with excavators from 5 tons to 50 tons (including CAT, Komatsu, Sany, and Volvo). Our buckets feature customizable opening widths and optional bolt-on cutting edges for easy field maintenance.

Unlocking Efficiency in Deep Foundations – HWX 360° Rotating Clamshell Bucket for Komatsu PC400
Location: Manila, Philippines
Project: Metro Station Deep Shaft Excavation
Equipment: Komatsu PC400-8 (40-Ton Class)
Attachment: 2.0m³ Heavy-Duty Rotating Clamshell Bucket

The Challenge: Precision Digging in Tight Spaces
A major infrastructure contractor in Manila faced a significant challenge during the construction of a new underground metro station. The project required excavating vertical shafts to a depth of 25 meters through a mix of heavy coastal silt and compacted clay.

The workspace was extremely congested, surrounded by pre-installed structural piles. A standard bucket was impossible to use due to the depth, and a non-rotating grab caused constant machine repositioning, wasting time and fuel.

The Solution: The HWX “Hydraulic Wrist”
To meet the project’s tight deadline, the client equipped their Komatsu PC400 with a 360° Rotating Clamshell Bucket.

Massive Capacity: The 2.0m³ bucket ensured each cycle moved maximum material.
Precision Control: The 360-degree infinite rotation allowed the operator to position the bucket perfectly between piles with surgical precision.
Mining-Grade Durability: Built with high-strength NM400 shells, the bucket was engineered to withstand the massive hydraulic pressure of the 40-ton machine.
The Outcome: 40% Increase in Productivity
The results were immediate. By eliminating the need to constantly move the excavator, the operator reduced cycle times significantly.

Efficiency: The cleanup and excavation speed increased by 40% compared to traditional methods.
Reliability: Despite working 24/7 in a high-humidity, saltwater-affected environment, the original NOK seal kits and reinforced cylinders showed zero leakage.
Cost Savings: The contractor saved an estimated 15% in fuel costs and met their excavation milestone two weeks ahead of schedule.
Client Feedback:
“Your clamshell bucket turned our PC400 into a specialized precision tool. For deep shaft work in urban areas, the 360-degree rotation is a game-changer. It’s the most reliable attachment in our fleet.” — Senior Project Manager, Manila.
