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.
For more information, read the article: What Is a Crane Grab Bucket?
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.
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.
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.
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.
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.
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.
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.

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.
Consider the material type, piece size, shape, and density. Scrap steel, mixed metal, rock, and other irregular materials may require different tine designs.
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.
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.
Check the crane or excavator capacity, hook or mounting connection, available lifting height, and working reach before selecting the grab.
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.

The gantry crane is a lifting equipment widely used across various industries, construction sites, ports, warehouses, and other fields. Its unique structure and powerful load-bearing capacity make it ideal for modern heavy-duty material handling. The “gantry” structure design allows the crane to move freely within a space, covering a large working area. So, what makes gantry cranes special? What are their types, parameters, control methods, applications, and working principles? How do they differ from bridge cranes? Let’s explore together. Types of Gantry Cranes Based on design, application, and operating environment, gantry cranes are typically categorized into the following types: Single-Girder Gantry Crane Single-girder gantry cranes are widely used across industrial sectors, warehouses, ports, and workshops. Featuring a single-girder support lifting mechanism, they traverse via side columns and bottom rails. With their simple structure, user-friendly operation, and moderate lifting capacity, they are ideal for handling light to medium loads. Capable of spanning large distances freely, single-girder gantry cranes are suitable for heavy material handling and lifting operations. Double Girder Gantry Crane Compared to single-girder gantry cranes, double-girder gantry cranes offer greater…
In ports, logistics parks, and industrial material handling, Portal Cranes and Gantry Cranes are two common and core loading/unloading equipment types. They differ in structural design, performance characteristics, operating methods, application scenarios, and investment costs. This article provides a comprehensive analysis of Portal Crane vs Gantry Crane and guides you in making the right selection. Structural Design Comparison The structural differences between Portal Cranes and Gantry Cranes primarily manifest in load-bearing methods, movement trajectories, and coverage ranges. The former centers on a fixed tower and rotating boom, emphasizing “point coverage” and flexible horizontal rotation. The latter features a portal frame structure and longitudinal rail travel, prioritizing “extensive horizontal movement” and efficient on-site logistics handling. Consequently, their distinct structural designs directly dictate their differing application scenarios. Portal Crane Structural Characteristics Portal slewing cranes employ single/double cantilever boom structures with the tower fixed to foundations or rails, enabling 360° or partial rotation. This configuration enables flexible operation in narrow, elongated spaces such as shorelines, dock fronts, and ship berths, making it particularly suitable for ship-to-shore material handling. Its core functionality combines vertical…
In modern industrial operations, efficient material handling is crucial for maximizing productivity and optimizing workflow. Bridge cranes, also known as overhead cranes or EOT cranes, are fixed material handling systems widely used in manufacturing, metal processing, warehousing, and loading/unloading operations. In this article, we will explore the working principle, main components, applications, and operational benefits of bridge cranes, providing a comprehensive guide for industrial planners and logistics professionals. Bridge Crane Working Principle A bridge crane operates on a bridge-like structure spanning the workspace, with a trolley and hoist system that moves horizontally along the bridge and vertically lifts or lowers loads. The crane’s movement across the runway, combined with precise hoist control, enables efficient and safe handling of heavy materials in factories, warehouses, and industrial facilities. For information on how overhead cranes work, please see this article: Overhead Crane Working Principle: Components, Motion & Operating Process Bridge Crane Terminology The following is an introduction to terminology related to bridge crane parts. Crane Capacity: Crane capacity refers to the maximum weight a bridge crane can safely lift. Typically measured in tons…
An EOT Crane (Electric Overhead Traveling Crane) is an efficient and reliable overhead lifting system used to handle heavy materials in factories, warehouses, workshops, and industrial plants. Running on overhead rails, EOT cranes enable safe and precise three-dimensional movement of loads through coordinated lifting, cross travel, and long travel motions. This article will guide you through EOT crane definitions, types, structure, working principles, applications, and cost factors to help you select the most suitable solution for your lifting needs. How EOT Crane Works? The working principle of an EOT crane involves a combination of vertical lifting, horizontal trolley movement, and longitudinal bridge travel, enabling efficient handling of heavy loads across industrial facilities. The crane operates on elevated runway rails installed along the building structure, with the bridge girder spanning the workspace. The hoist mechanism raises or lowers the load using steel wire ropes or chains, while the trolley moves the load horizontally along the bridge. The entire crane travels longitudinally along the runway rails, enabling three-dimensional positioning of materials. Modern EOT cranes are powered by electric motors with precise speed…
