Grab Bucket
Grab Bucket
Grab Bucket
The crane grab is a type of lifting equipment accessory specifically designed for grasping bulk materials (such as coal, ores, sand and gravel, scrap steel, wood, etc.). It achieves the grasping, lifting and discharging of materials through mechanical or hydraulic drive.The grab operation does not require strenuous physical labor, has high loading and unloading efficiency, and is safe and reliable. It is the main dry bulk cargo handling tool in ports.
Kinocranes grab robust construction, hydraulic control system, and high gripping strength, the Hydraulic Grab Bucket offers exceptional performance and productivity in construction sites, ports, and industrial operations.
Port and Logistics
Handling bulk cargo (coal, minerals, grains) with high efficiency, replacing manual labor.
Metallurgy And Mining
Heavy-duty grab buckets for handling iron ore and scrap steel; multi-flanged grab buckets for sorting scrap metals.
Waste Disposal
Garbage grabbers are used in incineration plants; straw grabbers are specially designed for biomass power plants.
Construction
Excavation of earth and rock, construction of ditches (using bucket grab equipment).
Kinocranes Grab Bucket
Kinocranes grab is mainly composed of jaw plates (2 or more pieces), upper crossbeam, lower crossbeam, pulley system and steel wire rope (or hydraulic cylinder). The jaw plates open and close to form the storage space, and the material is picked up and released by external force driving.
Kinocranes is a professional manufacturer of grabs.At Kinocranes, we are committed to delivering high-quality and innovative solutions for material handling challenges. Our Grab Bucket is designed with reliability and customer satisfaction in mind. Choose Kinocranes for superior performance, durability, and exceptional service.
Grab Types
Orange Peel Grab
The teeth of the orange peel grab bucket are made of high-strength wear-resistant steel structure. They operate smoothly and have high efficiency. However, the price is higher than that of mechanical grab buckets, and the maintenance cost in the later stage is relatively higher. This type of grab bucket is mainly used for loading and unloading large granular or block materials, such as ores, iron blocks, coal blocks, etc. The orange peel grab bucket can be divided into four-petal, five-petal and six-petal types according to the number of jaw blades.
The shell grab is suspended on the bucket arm of a crane or excavator for use. When opened, the grab presses or embeds the materials, and then the hydraulic cylinder pushes the jaw plates to close and grasp the materials. It is widely used in the excavation of building foundations, deep pit digging, loading of mud, coal, and gravel, and is particularly suitable for operations in ditches or restricted spaces. It is also applicable for loading and unloading bulk materials, minerals, and coal at ports, docks, station freight yards, mines, etc.
Products suitable for Grab Bucket
The grab is applicable to bridge cranes, gantry cranes and excavators.

Grab Bucket FAQ Content
CATEGORY 1：Selection & Technology
Q: What main types of grab buckets do you supply, and how to select the right model?
A: We provide full series grab buckets including single rope, double rope, four rope mechanical grab, hydraulic clamshell grab, orange peel grab, cactus grab and radio remote control grab. They match overhead cranes, gantry cranes and excavators.
Key selection factors: bulk material type (coal, ore, scrap steel, garbage, grain), supporting equipment (crane/excavator), working environment (port, metallurgy, waste disposal, construction), required grabbing capacity and budget.
- Hydraulic clamshell grab: Suitable for mud, gravel, foundation excavation and general bulk cargo; compact for narrow spaces.
- Orange peel grab (4/5/6 petals): For large block ores, iron scraps, high wear-resistance but higher cost and maintenance cost.
Q: What is the difference between hydraulic clamshell grab and orange peel grab bucket?
A: Hydraulic clamshell grab adopts two-piece jaw plates driven by hydraulic cylinder:
- Low cost, simple maintenance, compact structure
- Ideal for sand, coal, mud, grain, ditch excavation and port bulk cargo handling
Orange peel grab is multi-petal wear-resistant steel grab:
- Strong gripping force for irregular block materials like ore, scrap steel, metal waste sorting
- Higher purchase price and later maintenance expense Widely used in metallurgy, mining and scrap recycling yards
Q: Which lifting equipment can your grab buckets be matched with?
A: Our grab buckets are compatible with three mainstream devices:
1.Overhead bridge cranes: Four rope / double rope mechanical grab bucket for port, factory bulk material storage
2.Gantry cranes: Heavy-duty grab for dock freight yard and outdoor stockyard
3.Excavators: Hydraulic clamshell grab for construction digging, dredging and waste handling
We support customized connection structures to fit your existing crane or excavator brand.
Q: What’s the difference between single rope, double rope and four rope mechanical grab bucket?
A: Single rope grab bucket adopts one set of wire rope, easy to install, low cost, suitable for light load and low-frequency warehouse handling.
Double rope grab bucket uses two groups of steel wire ropes, stable operation, medium grabbing capacity, widely used for general factory bulk cargo.
Four rope grab bucket with four groups of wire ropes owns stronger bearing capacity, stable opening and closing performance, perfect for heavy-duty port continuous loading and unloading of coal, mineral grain.
Q: What materials are your grab bucket jaw plates made of, and how long is the service life?
A: Standard grab jaw plates adopt high-strength manganese wear-resistant steel, which resists abrasion from ore, gravel and scrap steel impact. For heavy wear scenarios, we can upgrade to NM450/NM500 wear-resistant steel plates.
Under normal medium-duty daily operation, standard grab jaw plates can work for 1–3 years; heavy-duty port and scrap steel yards can extend service life by 30% after wear plate thickening customization.
Q: Can grab buckets be retrofitted onto existing overhead cranes without large modification?
A: Most mechanical rope grab buckets can be matched with existing overhead cranes with simple pulley and rope adjustment, no large-scale beam modification required.
If you plan to install hydraulic grab buckets on overhead cranes, we will design matched hydraulic power units and connecting brackets according to your crane structure to minimize factory reconstruction work.
Q: What bulk materials can your grab buckets handle normally?
A: Our grab bucket series covers nearly all mainstream bulk cargo:
- Mineral & energy materials: coal, iron ore, limestone, grain, sand and gravel
- Metal recycling: scrap steel, metal blocks, metal slag
- Environmental waste: municipal garbage, straw, incineration slag
- Construction materials: mud, earth, rock, foundation excavation muck
Different grab types are recommended for different material shapes and density.
CATEGORY 2：Customization, Standards & Safety
Q: Can you customize grab buckets for special harsh working conditions?
A: Yes, we offer tailor-made grab solutions for different tough scenarios:
- High temperature metallurgy: Heat-resistant steel grab buckets for hot scrap steel and high-temperature mineral materials
- Dust & corrosive port environment: Fully sealed hydraulic components, anti-corrosion paint and thickened wear plates
- Waste incineration plant: Special garbage grab with anti-sticking jaw plates
- Explosion-proof sites: Explosion-proof hydraulic & electrical parts for chemical bulk cargo handling
Q: What international certifications do your grab buckets have?
A: All Kinocranes grab buckets pass global mainstream certification standards: CE, ISO, SGS. They comply with FEM crane design norms and meet import inspection requirements for Southeast Asia, Middle East, Europe, Africa and North America.
We have 18+ years export experience, supporting complete certification documents for customs clearance in over 100 countries.
