Changyu’s shell grab works mainly through two buckets, one on the left and one on the right. The buckets open to take in material, close to carry it, and open again to unload. The design delivers a high grip rate, strong closing force, and a high material filling rate.
These three points matter in daily work:
• Grip rate: A better grip keeps more material in the bucket while the excavator swings.
• Closing force: Strong closing force holds mixed loads, such as soil with small stones, without letting them slip out.
• Filling rate: A fuller bucket moves more material in every cycle, so you need fewer cycles per shift.
In practice, this helps operators load faster and spill less. For distributors, it gives you a product that is easy to explain to end users.
A grab bucket also needs a correct connection to the excavator arm. Many contractors use a Hydraulic Quick Hitch Coupler to change attachments faster on site. If you plan to do this, tell our team which coupler or pin setup your machine uses. We will help you confirm the connection details before you order.
Excavator size is only the starting point. Arm length, lifting capacity, and material type also decide whether a model is the right match.
Typical loose materials for this type of clamshell grab include sand, gravel, soil, and crushed stone. Always tell your supplier what you plan to handle. Material size, moisture, and density affect both bucket choice and daily wear.https://docs.google.com/document/d/1O_EK2BH67YBspUPWKNXZVTl7AlPzMExlPJByUNmilH8/edit?tab=t.0
Durability depends on build quality. Changyu has invested in advanced equipment, including robotic automatic welding, to support product quality and production efficiency. When you compare suppliers, ask about these points:
• Steel grade used in the main structure
• Wear protection on cutting edges and contact areas
• Weld quality and the condition of pivot points
• Pins, bushings, and other moving parts
• Surface treatment and paint
Share your working conditions with our team. We will confirm which options are available for your project.

• ZD05 – For 5–8 ton excavators. Capacity 0.35 m³, weight 467 kg. A compact option for small-scale loading and light earthwork.
• ZD20 – For 20 ton excavators. Capacity 1 m³, weight 1,340 kg. A balanced choice for general loading and earthwork.
• ZD30 – For 30 ton excavators. Capacity 1.5 m³, weight 1,538 kg. Suits larger sites with higher material volume.
• ZD35 – For 35 ton excavators. Capacity 1.8 m³, weight 1,805 kg. The largest model in the range, with a 1,400 mm inner width.
If your excavator falls between two listed classes, such as 10 to 19 tons, send us your machine details. Our team will review them and advise on the next step.
Bucket capacity in this range runs from 0.35 m³ to 1.8 m³. Capacity shows the rated volume of the bucket. It does not show the real load weight.
Material density changes the load. One cubic meter of dry sand weighs roughly 1.5 tons, and wet soil can weigh more. A full bucket of heavy material can exceed your excavator’s lifting capacity at long reach. Always check the lifting chart for your machine at the working radius you need.
A simple rule helps here: choose capacity based on the heaviest material you will handle, not the lightest.
Specifications may be updated. Please confirm the final data with our sales team before you place an order.
• Loading loose material onto trucks
• Moving material from stockpiles to hoppers
• Earthwork projects that involve digging and moving soil
• Lifting material from deep or narrow spots
If your work involves bulky or irregular items instead of loose material, compare this product with our Hydraulic Peel Grapple. Choosing the right attachment early helps you avoid a wrong purchase.
Contractors on these projects often share three needs: steady output, easy maintenance, and fast access to spare parts. Raise these points early with your supplier. Ask how spare parts and technical support are handled after delivery.
A typical work cycle looks like this:
1. The operator lowers the open bucket onto the material.
2. The two buckets close and fill with material.
3. The operator lifts the load and swings it to the target point.
4. The buckets open, and the material drops out.
The cycle repeats with little change in machine position, which keeps loading smooth and predictable.
1. Excavator weight class: Compare your machine with the tonnage range of each model.
2. Lifting capacity: Check the lifting chart at your working radius.
3. Material density: Plan for the heaviest material you will handle.
4. Connection: Confirm the pin diameter, arm width, and hitch type.
5. Working conditions: Consider shift length, site type, and wear level.
When you send an inquiry, include your machine brand and model, tonnage, arm connection details, material type, and destination country. This helps us reply with a precise recommendation.
Many fleets use both. If you also need a standard bucket for digging, visit our Digging Bucket page to compare options.

Excavator Grab Bucket 5-35T | Clamshell Grab Manufacturer
Loading loose material with a standard bucket wastes time. Material spills during the swing, cycles run longer, and the operator works harder than necessary. An excavator grab bucket solves this problem. It closes around the load like a clamshell, holds it during the swing, and opens over the truck, hopper, or stockpile.
Jiangyin Changyu Machinery Co., Ltd. builds a clamshell grab bucket range for excavators from 5 to 35 tons. This guide explains how a grab bucket works, which model suits which machine, what to check before you order, and how to prepare an inquiry. It is written for importers, distributors, contractors, and purchasing teams who compare suppliers before they request a quote.
Excavator Grab Bucket with High Grip Rate and Strong Closing Force

Clamshell Grab Bucket for 5-35 Ton Excavators
The range covers four models, from the ZD05 for 5–8 ton excavators to the ZD35 for 35 ton machines. This gives buyers a practical choice for compact jobs, medium earthwork, and larger loading sites.A grab bucket also needs a correct connection to the excavator arm. Many contractors use a Hydraulic Quick Hitch Coupler to change attachments faster on site. If you plan to do this, tell our team which coupler or pin setup your machine uses. We will help you confirm the connection details before you order.
Excavator size is only the starting point. Arm length, lifting capacity, and material type also decide whether a model is the right match.
Shell Grab Bucket with High Material Filling Rate
Filling rate describes how fully the bucket fills in each cycle. A shell grab bucket with a high filling rate moves more material per pass. Over a long project, that adds up to real savings in fuel, time, and labor.Typical loose materials for this type of clamshell grab include sand, gravel, soil, and crushed stone. Always tell your supplier what you plan to handle. Material size, moisture, and density affect both bucket choice and daily wear.https://docs.google.com/document/d/1O_EK2BH67YBspUPWKNXZVTl7AlPzMExlPJByUNmilH8/edit?tab=t.0
Light and Durable Grab Bucket Structure for Heavy-Duty Work
The overall structure of the Changyu grab bucket is light and durable. Light weight matters because the attachment’s own weight reduces the load your excavator can lift. For example, the ZD20 weighs 1,340 kg and has a 1 m³ capacity. The ZD30 weighs 1,538 kg and has a 1.5 m³ capacity.Durability depends on build quality. Changyu has invested in advanced equipment, including robotic automatic welding, to support product quality and production efficiency. When you compare suppliers, ask about these points:

Grab Bucket for Material Loading and Earthwork Projects
The excavator grab bucket suits jobs where material must be picked up, carried, and released in a controlled way. Common uses include:• Loading loose material onto trucks
• Moving material from stockpiles to hoppers
• Earthwork projects that involve digging and moving soil
• Lifting material from deep or narrow spots
If your work involves bulky or irregular items instead of loose material, compare this product with our Hydraulic Peel Grapple. Choosing the right attachment early helps you avoid a wrong purchase.
Excavator Clamshell Bucket for Road and Railway Construction
Road and railway projects move large volumes of fill, aggregate, and soil. An excavator clamshell bucket helps crews load this material quickly and release it where it is needed. Because the grab lifts and drops material vertically, it can work well along narrow corridors and next to existing structures, where space is limited.Contractors on these projects often share three needs: steady output, easy maintenance, and fast access to spare parts. Raise these points early with your supplier. Ask how spare parts and technical support are handled after delivery.
What Is an Excavator Grab Bucket and How Does It Work?
An excavator grab bucket is an attachment that grips, lifts, and releases loose material using two opposing bucket halves. Many buyers also call it a clamshell grab, because its shape and action resemble a clamshell.A typical work cycle looks like this:
1. The operator lowers the open bucket onto the material.
2. The two buckets close and fill with material.
3. The operator lifts the load and swings it to the target point.
4. The buckets open, and the material drops out.
The cycle repeats with little change in machine position, which keeps loading smooth and predictable.
What Size Grab Bucket Fits My Excavator?
Match the grab bucket to your machine, not just to its tonnage. Check these five items:1. Excavator weight class: Compare your machine with the tonnage range of each model.
2. Lifting capacity: Check the lifting chart at your working radius.
3. Material density: Plan for the heaviest material you will handle.
4. Connection: Confirm the pin diameter, arm width, and hitch type.
5. Working conditions: Consider shift length, site type, and wear level.
When you send an inquiry, include your machine brand and model, tonnage, arm connection details, material type, and destination country. This helps us reply with a precise recommendation.
Grab Bucket vs Digging Bucket: Which One Do You Need?
Both attachments fit an excavator, but they do different jobs. The table shows the main differences.| Factor | Grab Bucket | Digging Bucket |
| Main job | Picks up, carries, and releases loose material | Cuts into ground and scoops material |
| Best for | Loading, vertical lifting, tight spaces | General digging, trenching, grading |
| Material control | Holds material while closed | Open front, so loose material can spill more easily |
| Typical use | Loading trucks, feeding hoppers | Excavation and general earthwork |
| Choose it if | You mainly move loose material | You mainly dig and shape ground |
