Product Overview

A Hydraulic Orange Peel Grab Bucket, also called a hydraulic cactus grab or electro-hydraulic orange peel grab, is a multi-tine attachment for handling scrap steel, metal scrap, rock, and other irregular materials. Hydraulic cylinders control the tines from multiple directions, reducing material slippage during loading and discharge.

It is used with overhead cranes, gantry cranes, port cranes, and excavators in recycling yards, steel mills, ports, and mines. Common crane-mounted models use 6 tines with capacities of 0.5–5.0 m³. Larger configurations can reach 20 m³.

Capacity, tine number, opening size, hydraulic pressure, and mounting connection can be customized. Working pressure is typically 180–260 bar for different crane and excavator systems.

Orange Peel Grab Configurations

Hydraulic Working Principle

مواصفات

Orange Peel Grab Buckets are available with different tine numbers to handle various scrap sizes, material shapes and loading conditions. Tine quantity affects the grab opening, contact area and material holding performance.

4-Tine Orange Peel Grab

The 4-tine design has a larger opening and wider tine spacing. It is used for oversized scrap steel, heavy steel pieces, rocks and demolition materials. The structure allows the grab to enter large material piles and handle bulky loads.

5-Tine Orange Peel Grab

The 5-tine configuration offers a balanced structure for general scrap handling. It is commonly used for mixed metal scrap, irregular steel pieces and bulk materials with different sizes.

6-Tine Orange Peel Grab

The 6-tine design increases the contact points between the grab and material. It is used for scrap steel, mixed scrap and irregular metal pieces that require stable gripping during lifting.

7–8 Tine Orange Peel Grab

The 7–8 tine configuration features narrower gaps between tines and a compact grabbing structure. It is used for small scrap pieces, metal fragments and mixed materials with loose or irregular shapes.

Hydraulic Working Principle

The grab tines are driven by hydraulic cylinders mounted between the upper frame and each tine. Extending the cylinders closes the tines around the load, while retracting them opens the tines for discharge. Each tine is driven by its own cylinder or cylinder pair, distributing the closing force around the load. This allows the grab to hold irregular scrap, rock, and other uneven materials without relying on a single closing point.

Working Cycle: Lower → Close → Lift → Open

1. Lowering: The open grab is lowered onto the scrap or bulk material. The retracted tines provide the maximum opening and allow the grab to penetrate the pile under its own weight.

2. Grabbing: The hydraulic cylinders extend and close the tines around the material. The closing force increases as the tines meet resistance. Hydraulic pressure holds the load during lifting.

3. Lifting: The crane or excavator lifts the closed grab and its load. The load is supported by the tines and hydraulic circuit, without rope tension to keep the grab closed.

4. Discharging: The hydraulic cylinders retract to open the tines at the discharge point. The operator can control the opening, including partial opening, when discharging into a hopper, truck bed, or stockpile.

The hydraulic cylinders control the tines directly, without a mechanical closing rope.

Why Use an Orange Peel Grab Bucket?

An orange peel grab uses multiple tines to grip irregular loads from several directions. This structure suits materials that are difficult to contain with a conventional two-shell grab.

• Better Grip on Irregular Loads: Multiple tines close around scrap steel, metal pieces, rock, and other uneven materials.
• Less Material Spillage: The tines surround the load during lifting and help keep loose or irregular pieces inside the grab.
• Deep Penetration: Tine tips can enter gaps in scrap piles and loose materials for better material capture.
• Hydraulic Control: Hydraulic cylinders provide direct control of tine opening and closing during loading and discharge.
• Heavy-Duty Construction: Wear-resistant steel can be used for tines and other high-wear parts in demanding handling conditions.
• Flexible Equipment Matching: The grab can be configured for overhead cranes, gantry cranes, port cranes, and excavators.

An orange peel grab is a practical choice for scrap yards, steel plants, ports, mines, and other sites handling irregular bulk materials.

Regular inspection and maintenance of crane grab buckets can extend their service life. For details, please refer to: Crane Grab Bucket Maintenance Tips to Extend Service Life.

How to Select a Hydraulic Orange Peel Grab Bucket

The right grab depends on the material, required capacity, tine configuration, and lifting equipment. Check the hydraulic system and working conditions before finalizing the grab size.

1. Material Type and Size

Consider the material type, piece size, shape, and density. Scrap steel, mixed metal, rock, and other irregular materials may require different tine designs.

2. Grab Capacity

Select the grab capacity according to material density and the required load per cycle. The grab weight must also fit within the crane or excavator lifting capacity.

3. Tine Configuration

Choose the number of tines according to material size and the required grip. Fewer tines provide a wider opening, while more tines give closer load coverage.

4. Lifting Equipment

Check the crane or excavator capacity, hook or mounting connection, available lifting height, and working reach before selecting the grab.

5. Hydraulic System

Match the working pressure, flow rate, and power supply with the available hydraulic system. Crane-mounted and excavator-mounted grabs use different hydraulic arrangements.

Select the grab configuration based on the material, equipment, and site conditions rather than capacity alone.

If you are considering using an overhead crane or gantry crane and are unsure how to select the appropriate grab bucket, see the article: How to Choose a Grab Bucket for Overhead Cranes and Gantry Cranes?

Hydraulic Orange Peel Grab Bucket vs. Hydraulic Clamshell Grab Bucket

Hydraulic Orange Peel Grab Buckets and Hydraulic Clamshell Grab Buckets both use hydraulic cylinders to open and close the grab. The main difference is the shell design. Orange peel grabs use multiple tines for irregular materials, while clamshell grabs use two shells for bulk materials.

Hydraulic Orange Peel Grab Buckets are mainly used for irregular and bulky materials such as scrap steel. Hydraulic Clamshell Grab Buckets are commonly used for loose bulk materials such as coal, sand, and ore. The material type and load shape are the main factors when selecting between the two.
