Introduction
Scrap steel handling requires grabbing equipment that can deal with irregular shapes, uneven weight distribution, and heavy loads. A hydraulic orange peel grab bucket for scrap steel handling uses hydraulic cylinders and multiple tines to provide stable gripping force for lifting and transferring scrap steel, metal blocks, slag, and other irregular materials. It is widely used in steel plants, scrap yards, ports, and recycling facilities.
In this article, I will introduce how hydraulic orange peel grab buckets work, their main structures, suitable applications, key specifications, and the factors to consider when selecting a suitable model. I will also compare orange peel grabs with other grab types and explain how WEIHUA provides customized solutions for different cranes and scrap handling conditions.
What Is a Hydraulic Orange Peel Grab Bucket?
A hydraulic orange peel grab bucket is a crane attachment that uses hydraulic cylinders to drive multiple curved tine shells for opening and closing. It is used for grabbing, lifting, and unloading irregular bulk materials. It is also known as an orange peel grab or multi-tine grab, named after the tine sections that resemble orange peel shapes.
Different from two-shell clamshell grabs, hydraulic orange peel grabs usually use 3, 6, or 8 tines, with each tine driven by a hydraulic cylinder. The structure includes hydraulic cylinders, tine shells, a hydraulic power unit, a control system, and wear-resistant parts. The pointed tine tips improve penetration into material piles, while Q345B steel and Hardox 450 wear plates are commonly used for heavy-duty operation.
The grab bucket integrates a hydraulic system and can operate after being connected to the crane power and control system. It can be installed on tower cranes, ship cranes, unloading machines, and overhead cranes. Orange peel grabs are designed for scrap steel, pig iron, ore, slag, stones, and waste handling, while clamshell grabs are mainly used for loose bulk materials. A 360° hydraulic rotation function is also available for operations in narrow areas such as ship holds and storage yards.

How Does a Hydraulic Orange Peel Grab Bucket Work?
A hydraulic orange peel grab bucket works by distributing hydraulic power to each tine cylinder to control synchronous opening and closing. The grab bucket has an integrated hydraulic system and can operate after connecting to the crane power supply, without additional pipelines.
Power supply and pressure building:
The external power supply drives the motor and hydraulic pump to generate pressurized oil. The hydraulic system adjusts pump flow according to working pressure.
Synchronous opening and closing:
Pressurized oil enters each tine cylinder through the valve block, driving multiple tines to open and close at the same time. Each tine is controlled by an independent cylinder, reducing material leakage during operation.
Penetration and grabbing:
The pointed tine tips penetrate material piles with lower resistance and stronger digging force. The grab bucket is suitable for scrap steel, pig iron, ore, slag, waste, and other irregular materials.
Rotation and unloading:
After lifting to the unloading position, the cylinders reverse to open the tines and release the materials. A 360° hydraulic rotation function can be added for adjusting the grabbing direction in narrow working areas.
The hydraulic drive system provides direct control of tine movement. The grabbing process is not affected by wire rope winding, providing stable cycles and reliable operation in dusty and impact environments.
Why Use Hydraulic Orange Peel Grab Bucket for Scrap Steel Handling?
Scrap steel has irregular shapes, uneven weight distribution, and heavy pieces, which require strong gripping performance. Hydraulic orange peel grab buckets are designed for these conditions and are widely used in steel plants, scrap yards, ports, and recycling facilities.
Strong gripping force for irregular scrap
Multiple tines surround the material and penetrate the scrap pile with low resistance. The closed tine structure provides stable holding force and reduces material leakage during lifting.
Suitable for heavy-duty scrap handling
The grab bucket is used for scrap steel, steel blocks, pig iron, slag, waste, and stones. It is suitable for handling large and irregular materials in harsh working conditions.
Flexible hydraulic control
The hydraulic system controls tine opening and closing for accurate grabbing and unloading. A 360° hydraulic rotation function is available for operations requiring position adjustment.
Wear-resistant structure
The grab body uses Q345B steel, and tine tips use Hardox 400 or Hardox 450 wear-resistant steel. Protective structures reduce damage from dust, impact, and continuous operation.
Hydraulic orange peel grab buckets provide stable gripping, wear resistance, and flexible control for scrap steel handling applications with high working intensity.
