Clamshell grab bucket overhead crane & Orange peal grab bucket overhead crane

According to the driving method of crane grab, grab overhead cranes can be can be divided into two types: hydraulic grab and mechanical grab. And also according the types of crane grab buckts, the grab overhead cranes can be grouped into clamshell grab crane & orange peal grab crane, etc.

Overhead c rane grabs are classified into two types: orange grabs and clamshell grabs. Yuantai Crane 's clashell buckets offerings are as follows:

Clamshell Buckets are used to load and unload materials such as sands, coal, mineral powder, and bulk chemical fertilizer. The Clamshell Bucket is designed to allow the overhead crane to grab bulk materials efficiently .

Crane peel grab for sale. Crane peel grabs are available in a variety of tine configurations, including 4 tine peel grabs, 5 tine peel grabs, 6 tine peel grabs, and so on. Yuantai Crane peel grab can handle scrap metal, waste and demolition products, coal, and other materials,etc.

Hydraulic grab crane - The hydraulic grab has an opening and closing structure that is typically powered by a hydraulic cylinder. A hydraulic claw is another name for a hydraulic grab with multiple jaws. Hydraulic grabs are a common component of hydraulic special equipment.
Mechanical grab crane -The mechanical grab has no opening and closing structure and is usually powered by a rope or a connecting rod. It is classified as a double rope grab or a single rope grab based on its operation characteristics. A double rope grab is the most frequently used grab bucket.

A support rope and an opening and closing rope are wound around the support mechanism and the reel of the opening and closing mechanism, respectively, in the double rope grab. The double rope grab is dependable, simple to use, productive, and widely used. When two sets of double ropes are used, it becomes a four-rope grab, with the same working process as the double rope grab. The single rope grab uses the same rope for the support rope, as well as the opening and closing rope.

The wire rope rotates to provide support and is opened and closed by a special locking device. The single rope grab's winding mechanism is simple, but its productivity is low, and it is rarely used in a large number of loading and unloading operations.

A grab double‑girder overhead crane is a type of heavy-duty crane designed specifically to handle bulk materials with speed and precision. Unlike single-girder cranes, the double-girder design allows it to carry heavier loads, cover longer spans, and operate reliably in demanding industrial environments. The “grab” mechanism – typically a clamshell or orange peel grab – makes it easy to lift and transport loose materials such as coal, scrap metal, grain, or biomass efficiently and safely.

These cranes are widely used in ports, power plants, steel mills, and other industrial facilities where large volumes of materials need to be moved regularly. The design emphasizes stability, long-term durability, and smooth operation under continuous or heavy-duty cycles.

Key advantages of grab double-girder overhead cranes include:

High capacity and heavy-duty performance: Can handle loads from 5 tons up to 80 tons or more, depending on design.
Efficient bulk material handling: Ideal for irregular, heavy, or loose materials like coal, scrap, sand, grain, and biomass.
Reliable operation in tough environments: Engineered for ports, industrial warehouses, power plants, and steel or mining facilities.
Customizable spans and heights: Can be designed for long spans up to 35 meters and lifting heights up to 20 meters to match your workshop or facility layout.

In short, these cranes are built for work. They focus on moving large volumes of material safely and efficiently, without unnecessary frills. If your operation involves frequent bulk handling or heavy-duty lifting, a grab double-girder crane is the practical choice to keep your workflow steady and productive.

Grab Device Types & Selection Guide

Choosing the right grab is just as important as selecting the crane itself. The grab type determines how efficiently materials are lifted, how fast operations run, and how safe the process is. Below is a practical guide to the main grab types used with double-girder overhead cranes:

Clamshell grabs are ideal for lifting loose, bulk materials. They move large volumes quickly and reliably, with minimal spillage or damage to the grab.

Best for: Bulk materials like coal, sand, grains, or similar loose materials.
Advantages: Simple and reliable design, efficiently lifts large volumes, easy to operate and maintain.
Typical applications: Power plants for coal handling, grain storage facilities or silos, sand or aggregate loading/unloading.

Orange peel grabs are designed for irregular, bulky, or messy materials. They are perfect for unevenly shaped materials that are difficult to contain.

Best for: Irregular scrap, demolition debris, or waste materials.
Advantages: Can grip uneven shapes securely, reduces spillage compared to clamshell grabs, faster cycles for irregular loads.
Typical applications: Scrap yards and recycling facilities, metal processing plants, demolition or waste management sites.

The grab mechanism itself can be hydraulic or mechanical. Your choice affects control, speed, and maintenance requirements.

Hydraulic grabs: Offer smoother and more precise operation, adjustable closing force to match different materials, slightly higher maintenance due to hydraulic systems.
Mechanical grabs: Simple, durable, and lower cost, faster cycles for uniform materials, less precise with irregular or delicate loads.

Always ensure the crane's lifting capacity matches the grab's full load, including a safety margin of 20–30%.

Example: If a clamshell grab holds 10 tons of coal, the crane should be rated for at least 12–13 tons.
This keeps operations safe and prolongs the life of both the crane and grab.
