Orange Peel Grab
Hydraulic Grab & Mechanical Grab Bucket

Why an orange peel grab? An Orange Peel Grab (also known as a Cactus Grab or Polyp Grab) will be used for objects that cannot be handled with a Clamshell Grab. The handled materials are either too large or the penetration into the handled materials is better with an Orange Peel Grab. The Orange Peel Grab can be completed with open shells, half closed shells, or fully closed shells, depending on the size and type of materials handled. The weight and execution of the Orange Peel Grabs are also determined by the materials that will be handled with the grab.The orange peel grab can b customized to the specific application.

The Orange Peel Grabs For Overhead Crane & Gantry Crane is a one-of-a-kind tool for handling dry bulk cargo. The crane grab operation does not require strenuous physical labor, can achieve high loading and unloading efficiency, and improved crane operation safe. It is the port's primary dry bulk handling tool. Orange peel grabs can be classified into ore grab, coal grab, grain grab, wood grab, and so on based on the type of goods.

Orange peel grab has been widely used with tower cranes, ship cranes, ship unloaders, crane cranes, and other types of cranes in ports, steel mills, power plants, ships, and garbage treatment plants.

What are types of orange peel grabs ?

• Mechanical Two Rope Operated Orange Peel Grabs -For Cranes with one holding rope and one closure rope
• Mechanical Four Rope Operated Orange Peel Grabs -For Cranes with two holding ropes and two closing ropes
• Hydraulic Orange Peel Grabs - For Hydraulic Machines or Excavators. Electro Hydraulic Orange Peel Grabs - For Cranes with only one hook, such as Mobile Harbour Cranes, Ship Cranes, or Overhead Cranes. The cranes should be outfitted with the necessary gear to operate these captures.
• Diesel Hydraulic Orange Peel Grabs – For cranes with only one hook. There are no further accessories required for operating. These grabs are powered by a diesel hydraulic power unit and may be easily linked up and controlled remotely.

Classifications of crane grabs based on the loading materials

Comprehensive application of electro-hydraulic pressure machinery technology, high gripping force, and a high degree of full automation, primarily used to process power and fine bulk materials such as chemicals, fertilizers, grain, coal, coke, iron ore, sand, granular building materials, and crushed materials, as stone tools, etc.

The grab bucket is typically classified into four basic types based on the characteristics of the grabbing material: light, medium, heavy, and super heavy.

The medium grab weight is roughly equal to the material weight, the light weight is smaller, and the heavy weight is larger. The corresponding parameters and structural types should be chosen for each type of grab. When the grain-size of the grab is larger than 100mm or more solid material, a jaw plate with teeth should be used. When using a grabbing quasi-rail vehicle, the grab volume should not exceed 3 m. The number of bucket jaw plates in a multi-claw (also known as lotus) grab is usually six, and the jaw plate cut is at a sharp angle, making it suitable for grabbing hard ore, aluminum ingots, iron scraps, and scrap steel, which are difficult to insert in a double jaw plate grab.

How do I select an orange peel grab?

When selecting an orange peel grab, consider the size and weight of the material you will be handling, the capacity of the grab, and the type of crane or excavator it will be attached to. It is also important to choose a grab with durable and high-quality materials to ensure longevity.

How to choose a suitable crane orange peel grab ? Simply,

• The power form of the grab bucket needs to be selected according to the type or mold of bulk material handling cranes, and
• the structure design of the grab bucket needs to be selected for the type of loads or object to be loaded and unloaded.
• And the features of grabs needs to be customized based on the application conditions and lifting requirements, etc. In the following, the selection tips are presented for your reference:

Factors affect your grab selections

Before selecting the type of grab, it is necessary to confirm the following information；

• Environment: working environment of the grab crane
• Loads: the objects or loads to be grabbed, including the cubic number of the object to be grabbed at one time, and the specific gravity of the material,etc.
• Equipment:  the capacity or tonnages of the grab crane used with the grab. Based on the grab crane equipment's information, decide which type of grab bucket to use. After confirming the type of grab bucket, confirm the opening direction of the grab bucket, which should be perpendicular to the crane's main girder or parallel to the crane's main girder.

What is the maximum capacity of an orange peel grab?

The maximum capacity of an orange peel grab can vary depending on the specific model and manufacturer. However, in general, the capacity can range from a few hundred kilograms to several tons. It is important to select the appropriate capacity based on the job requirements to ensure safe and efficient operation. Factors to consider when selecting an orange peel grab include the type and density of the material being handled, the size and weight of the grab itself, and the lifting capacity of the crane or other equipment being used.

Can an orange peel grab be used for both light and heavy materials?

Yes, an orange peel grab can be used for both light and heavy materials. However, it is important to select the appropriate size and capacity of the grab based on the specific material being handled. The size and capacity of the grab will impact its efficiency and effectiveness in handling the materials. It is recommended to consult with a professional or the manufacturer to determine the best grab for your specific needs.

What is the difference between a mechanical and hydraulic orange peel grab?

A mechanical orange peel grab is operated manually and requires physical effort from the operator to open and close the grab. On the other hand, a hydraulic orange peel grab is powered by hydraulic cylinders, which makes it easier to operate and requires less physical effort. Additionally, hydraulic orange peel grabs can be operated remotely, which can increase efficiency and safety in certain applications. However, hydraulic grabs are generally more expensive and require more maintenance than mechanical grabs. Ultimately, the choice between a mechanical or hydraulic orange peel grab will depend on the specific needs and requirements of the application.

Hydraulic orange peel grab vs. Mechanical orange peel grab

There are two types of Orange Peel Grabs, also called Cactus Grabs, which can be grouped into hydraulic grab and mechanical bucket. For the hydraulic grab, a rotator is an optional feature that can be installed to ensure accurate and efficient placing of the loads over a truck or in a pile. They can be classified into peel grabs with four tines, five tines, six tines, etc., depending on the structure of the orange peal grab petal. These crane grabs come in open, semi-closed, and closed tine configurations. Both hydraulic and mechanical orange peel grabs are capable of handling any heavy-duty tasks, including handling waste, recycling, gravel, wood chips, scrap metal, etc.

Hydraulic Crane Orange Peel Grab
The hydraulic grab is equipped with an opening and closing mechanism, which is usually driven by a hydraulic cylinder. The term "hydraulic grab" also refers to the device with multiple jaw plates.
Main parameters of hydraulic orange peel grabs:
Rated grabbing weight: 3.2 tons to 30 tons;
Grab volume -0.10m3~60.0m3.

Mechanical Crane Orange Peel Grab
The mechanical bucket is not equipped with an opening and closing mechanism, which is typically powered by the external force of the rope or connecting rod.
Main parameters of mechanical grab buckets:
Rated grabbing weight: 3.2t~63.0t;
Grab volume -0.20m3~60.0m3.

Clamshell grab vs orange peel grab

What is the different of a clamshell grab and orange peel grab ? The main difference between a clamshell grab and an orange peel grab is in their design and the way they operate.

A clamshell grab typically has two hinged buckets that open and close to grip and release materials. It is used for handling loose materials such as sand, gravel, and soil. The grab can be operated by a single rope or two ropes, depending on the design.

An orange peel grab, on the other hand, features multiple tines that open and close in a scissor-like motion to grip and release materials. It is designed for handling bulk materials such as scrap metal, rocks, and coal. The grab is typically operated by two ropes, and its tines can be adjusted to accommodate different sizes and shapes of materials.

While both types of grabs are used in material handling applications, their specific design features make them better suited for different types of materials and applications.

Clam shell grab
It can be used to load a variety of bulk cargoes, including minerals, coal, sand, gravel, and earth and stone, into trucks and cargo yards, mines, etc. Additionally, it can be used in projects like laying railroad tracks, building roads, excavating foundations and trenches,etc.

Multi-petal grab
It is appropriate for scrap steel grabbing and sorting work in steel mills, bulk waste in waste treatment plants and construction sites, waste sorting, loading and unloading and handling work, and auto recycling yards for car disassembly, sorting, and recycling. Bucket teeth can be replaced and high-hardness steel can be used to ensure long service life. There are four types of valve shells that can be chosen depending on the working environment: fully closed, semi-closed, broad-sided, and narrow-sided.

How do I properly maintain and care for my orange peel grab?

To properly maintain and care for your orange peel grab, you should follow these steps:

• Clean the grab after each use to prevent rust and corrosion. Use a wire brush to remove any debris and then wipe it down with a clean cloth.
• Check the hydraulic hoses and connections regularly for leaks or damage. Replace any damaged parts immediately.
• Lubricate all moving parts of the grab regularly to ensure smooth operation. Use a high-quality lubricant and follow the manufacturer's recommendations.
• Inspect the grab for wear and tear, such as cracks or bent tines. Replace any damaged parts immediately to prevent further damage.
• Store the grab in a dry, protected area when not in use. Cover it with a tarp or other protective covering to prevent dust and debris from accumulating.
• By following these maintenance and care tips, you can extend the life of your orange peel grab and ensure it operates safely and efficiently.
