This guide explains how a Hydraulic Peel Grapple works, what specifications matter before placing an order, and how Changyu Machinery supports importers, distributors, and OEM buyers with reliable supply and technical backup. If you are comparing suppliers or preparing a purchase order, the sections below cover the practical details procurement teams usually ask for.
A Hydraulic Peel Grapple — sometimes called an orange peel grapple — is an excavator attachment made of several curved jaws (tines) that open and close around bulk or irregular material. The jaws are driven by a hydraulic cylinder, letting the operator grip, lift, rotate, and release material with precision.
The name comes from the shape of the open jaws, which resemble an orange peel when fully extended. This design lets the attachment penetrate deep into a pile of loose material and close firmly around it, rather than pushing material aside the way a standard bucket does.
Buyers typically look for this attachment when a bucket or clamshell grab isn't precise enough for handling scrap metal, demolition waste, or mixed loose material on a jobsite or in a recycling yard.
Most models also include a rotation function, powered by a separate hydraulic motor, so the operator can rotate the grapple 360 degrees without repositioning the excavator boom. This is especially useful when loading trucks or sorting material by type, since the operator can pick up material in one orientation and release it in another without extra machine movement.
Because the entire grip-and-release cycle is hydraulic, the attachment responds quickly and gives the operator fine control over closing force — important when handling fragile or mixed-size material.
• Jaws (tines): Curved steel claws — usually 4 or 5 per unit — that close around the material.
• Hydraulic cylinder: Drives the opening and closing motion of the jaws.
• Rotation motor: Allows 360-degree rotation for flexible loading and unloading.
• Mounting bracket: Connects the grapple to the excavator's boom or quick hitch coupler.
• Pin and bushing connections: Allow the jaw linkage to move smoothly under repeated load cycles.
Each part is exposed to constant friction, impact, and pressure, so the steel grade and welding quality directly affect service life. Buyers sourcing from a manufacturer should ask for details on the steel used for the jaws and the wear protection at high-friction points before finalizing an order.
When comparing specifications across suppliers, pay attention to three numbers in particular: the applicable excavator weight range, the maximum opening (which determines how much material it can grip in one cycle), and the total attachment weight (which must stay within your excavator's rated lifting capacity).
• 3-tine grapples are lighter and suited to bulky, low-density material where speed matters more than a tight grip.
• 4-tine grapples are the most common configuration, balancing grip strength and material penetration — a good default for mixed scrap and demolition debris.
• 5-tine grapples close more tightly around smaller or irregular pieces, reducing material loss during lifting, useful in recycling operations where every kilogram counts.
Changyu's ZJM4 series is available in both 4-jaw and 5-jaw configurations across all three model sizes, so buyers can match the tine count to the material type without switching to a different frame size.
Before ordering, buyers should confirm two things with their excavator specifications:
• The auxiliary hydraulic flow rate (liters per minute) must match the grapple's rated flow.
• The system pressure must fall within the grapple's operating range to avoid under-powered clamping or premature seal wear.
This is one of the most common technical questions Changyu receives from procurement teams, and it's worth confirming before placing a purchase order — mismatched flow or pressure is the most frequent cause of poor field performance.
For scrap yards handling high daily tonnage, the rotation function also speeds up truck loading, since operators can rotate the load into position instead of repositioning the excavator each time.
Contractors working on teardown projects often pair a Hydraulic Peel Grapple with a Hydraulic Quick Hitch Coupler so the crew can switch between the grapple, a bucket, or a breaker without leaving the cab — useful on mixed-scope demolition jobs where the material type changes throughout the day.
• 15–18 ton excavators — ZJM4-180, suited to smaller demolition and yard-loading work.
• 20–30 ton excavators — ZJM4-280, the most common size for mid-scale scrap and demolition operations.
• 31–41 ton excavators — ZJM4-380, built for high-volume scrap yards and large demolition projects.
If your excavator falls outside these ranges, or you run mixed brands across a fleet, Changyu's engineering team can review your machine specifications and confirm the correct mounting configuration before shipment.
Changyu Machinery has manufactured hydraulic attachments — including breakers, grapples, and crushing equipment — for over 13 years, with products exported to more than a dozen countries across the Middle East, Africa, and Asia. For international buyers, working directly with a manufacturer rather than a trading company typically means:
• Direct factory pricing without a middleman markup
• Faster response on technical questions, since the team building the product answers directly
• More flexibility for OEM/ODM requests and custom specifications
• Consistent supply for repeat orders, which matters for distributors managing regional stock
Buyers evaluating suppliers are welcome to review Changyu's Hydraulic breaker range alongside the grapple lineup, since many customers order both product lines together for a single project. You can also learn more About Us and Changyu's manufacturing background.
Because this attachment operates in an abrasive, high-cycle environment, buyers should treat wear resistance as a core spec — not a marketing detail — and ask suppliers directly about the steel grade and heat treatment process used on the jaws before confirming an order.
• Custom mounting brackets to match specific excavator brands and models
• Adjustable jaw opening width based on the target material
• Tine count selection (4 or 5) per customer requirement
• OEM branding and packaging for distributors and resellers
For buyers preparing an inquiry, sending the excavator brand, model, and boom pin dimensions upfront speeds up the quotation and avoids compatibility issues after shipment.
For buyers, this means search results and supplier catalogs under either name typically refer to the same product category. When requesting quotes, it's worth using both terms with your supplier to confirm you are comparing equivalent specifications, since minor differences in jaw shape or cylinder placement can exist between manufacturers even within the same general category.
Routine maintenance is limited to a few recurring tasks:
• Greasing pivot points on a regular schedule
• Inspecting jaw edges and cylinder seals for wear
• Checking hydraulic hose connections for leaks after the first weeks of operation
For buyers placing their first order, Changyu also offers guidance on spare parts stocking, so distributors can support end customers locally without waiting on international shipping for common wear items.
It depends on the model. Changyu's range covers 15–18 ton, 20–30 ton, and 31–41 ton excavator classes. Sending your excavator model to the sales team confirms the correct match.
Is a Hydraulic Peel Grapple the same as an orange peel grapple?
Yes. Both terms refer to the same attachment type — the naming difference comes from region and supplier preference rather than a difference in function.
Can the grapple be customized for my excavator brand?
Yes. Mounting brackets, jaw opening width, and tine count can be adjusted based on your excavator brand and the material you are handling.
How many tines should I choose — 4 or 5?
4-tine grapples suit general scrap and demolition work. 5-tine grapples grip smaller or irregular material more tightly, which reduces material loss in recycling applications.
Does Changyu support OEM and private-label orders?
Yes. Changyu works with distributors and brand owners on OEM branding, custom packaging, and private-label supply arrangements.
What information should I send to get an accurate quote?
Your excavator brand, model, weight class, boom pin dimensions, and intended application (scrap, demolition, or general material handling) are enough for the sales team to prepare an accurate quotation.
Changyu Machinery manufactures the ZJM4 series directly, supporting international buyers with factory pricing, customization, and technical guidance from order through installation.

Hydraulic Peel Grapple – Scrap & Demolition Attachment | Changyu
Introduction
International buyers sourcing scrap-handling and demolition equipment usually ask the same question: which excavator attachment actually holds up under daily loading and unloading cycles? A Hydraulic Peel Grapple answers that directly. Built to grip irregular, bulky, and loose materials — from twisted scrap steel to construction rubble — it is one of the most requested attachments among recycling yards, demolition contractors, and waste management companies worldwide.This guide explains how a Hydraulic Peel Grapple works, what specifications matter before placing an order, and how Changyu Machinery supports importers, distributors, and OEM buyers with reliable supply and technical backup. If you are comparing suppliers or preparing a purchase order, the sections below cover the practical details procurement teams usually ask for.
What Is a Hydraulic Peel Grapple?
A Hydraulic Peel Grapple — sometimes called an orange peel grapple — is an excavator attachment made of several curved jaws (tines) that open and close around bulk or irregular material. The jaws are driven by a hydraulic cylinder, letting the operator grip, lift, rotate, and release material with precision.
The name comes from the shape of the open jaws, which resemble an orange peel when fully extended. This design lets the attachment penetrate deep into a pile of loose material and close firmly around it, rather than pushing material aside the way a standard bucket does.
Buyers typically look for this attachment when a bucket or clamshell grab isn't precise enough for handling scrap metal, demolition waste, or mixed loose material on a jobsite or in a recycling yard.
How a Hydraulic Peel Grapple (Orange Peel Grapple) Works
The working principle is straightforward. A hydraulic cylinder connects to the jaw linkage system. When the operator activates the circuit, hydraulic oil pushes the piston, forcing the jaws to close around the material. Reversing the flow opens the jaws again.Most models also include a rotation function, powered by a separate hydraulic motor, so the operator can rotate the grapple 360 degrees without repositioning the excavator boom. This is especially useful when loading trucks or sorting material by type, since the operator can pick up material in one orientation and release it in another without extra machine movement.
Because the entire grip-and-release cycle is hydraulic, the attachment responds quickly and gives the operator fine control over closing force — important when handling fragile or mixed-size material.
Hydraulic Peel Grapple Structure & Key Components
A typical Hydraulic Peel Grapple is built from these core parts:• Jaws (tines): Curved steel claws — usually 4 or 5 per unit — that close around the material.
• Hydraulic cylinder: Drives the opening and closing motion of the jaws.
• Rotation motor: Allows 360-degree rotation for flexible loading and unloading.
• Mounting bracket: Connects the grapple to the excavator's boom or quick hitch coupler.
• Pin and bushing connections: Allow the jaw linkage to move smoothly under repeated load cycles.
Each part is exposed to constant friction, impact, and pressure, so the steel grade and welding quality directly affect service life. Buyers sourcing from a manufacturer should ask for details on the steel used for the jaws and the wear protection at high-friction points before finalizing an order.
Hydraulic Peel Grapple Specifications & Technical Parameters
Specifications vary depending on the excavator class the grapple is designed for. Below is the technical parameter range for Changyu's current Hydraulic Peel Grapple lineup:| Model | Applicable Excavator Weight (Ton) | Boom Installation | No. of Jaws | Max Opening (mm) | Weight (kg) |
| ZJM4-180 | 15–18 | Forearm installation | 4–5 | 1600 | 900 |
| ZJM4-280 | 20–30 | Forearm installation | 4–5 | 2500 | 1900 |
| ZJM4-380 | 31–41 | Forearm installation | 4–5 | 2900 | 2200 |
Tine Configuration: 3, 4 & 5-Tine Hydraulic Peel Grapples
The number of tines affects how the grapple performs with different materials:• 3-tine grapples are lighter and suited to bulky, low-density material where speed matters more than a tight grip.
• 4-tine grapples are the most common configuration, balancing grip strength and material penetration — a good default for mixed scrap and demolition debris.
• 5-tine grapples close more tightly around smaller or irregular pieces, reducing material loss during lifting, useful in recycling operations where every kilogram counts.
Changyu's ZJM4 series is available in both 4-jaw and 5-jaw configurations across all three model sizes, so buyers can match the tine count to the material type without switching to a different frame size.
Rotation System & Hydraulic Pressure Explained
The rotation motor and the hydraulic pressure rating of the excavator's auxiliary circuit determine how smoothly the grapple performs on site. A grapple that rotates freely reduces the number of boom repositions per cycle, which speeds up loading and lowers fuel consumption over a full shift.Before ordering, buyers should confirm two things with their excavator specifications:
• The auxiliary hydraulic flow rate (liters per minute) must match the grapple's rated flow.
• The system pressure must fall within the grapple's operating range to avoid under-powered clamping or premature seal wear.
This is one of the most common technical questions Changyu receives from procurement teams, and it's worth confirming before placing a purchase order — mismatched flow or pressure is the most frequent cause of poor field performance.
Applications: Scrap Metal Handling & Recycling
Recycling yards use Hydraulic Peel Grapples to load and sort scrap steel, aluminum, and mixed metal from stockpiles into trucks, shredders, or sorting bins. The jaw curve grips irregular pieces — twisted rebar, sheet offcuts, cable, and machine parts — more securely than a standard bucket, reducing material spillage during transfer.For scrap yards handling high daily tonnage, the rotation function also speeds up truck loading, since operators can rotate the load into position instead of repositioning the excavator each time.
Applications: Demolition & Construction Waste Sorting
On demolition sites, the same grapple handles concrete rubble, broken masonry, wood, and mixed construction waste. Because the jaws penetrate into a pile rather than scraping across the surface, they are effective for clearing collapsed structures and sorting recoverable material from waste destined for disposal.Contractors working on teardown projects often pair a Hydraulic Peel Grapple with a Hydraulic Quick Hitch Coupler so the crew can switch between the grapple, a bucket, or a breaker without leaving the cab — useful on mixed-scope demolition jobs where the material type changes throughout the day.
Compatible Excavator Models & Weight Classes
Since the grapple mounts directly onto the excavator boom, matching the correct weight class is essential:• 15–18 ton excavators — ZJM4-180, suited to smaller demolition and yard-loading work.
• 20–30 ton excavators — ZJM4-280, the most common size for mid-scale scrap and demolition operations.
• 31–41 ton excavators — ZJM4-380, built for high-volume scrap yards and large demolition projects.
If your excavator falls outside these ranges, or you run mixed brands across a fleet, Changyu's engineering team can review your machine specifications and confirm the correct mounting configuration before shipment.

Build Quality: High-Strength Wear-Resistant Steel & Durability
The jaws and structural frame of Changyu's Hydraulic Peel Grapple are built from high-strength, wear-resistant steel to withstand repeated impact against scrap and rubble. Pivot points are designed for greaseable maintenance access, which extends service life between overhauls and reduces unplanned downtime.Because this attachment operates in an abrasive, high-cycle environment, buyers should treat wear resistance as a core spec — not a marketing detail — and ask suppliers directly about the steel grade and heat treatment process used on the jaws before confirming an order.
Customization Options for Different Machine Brands
Excavator brands use different boom and quick-hitch dimensions, so most Hydraulic Peel Grapple orders require some level of customization. Changyu supports:• Custom mounting brackets to match specific excavator brands and models
• Adjustable jaw opening width based on the target material
• Tine count selection (4 or 5) per customer requirement
• OEM branding and packaging for distributors and resellers
For buyers preparing an inquiry, sending the excavator brand, model, and boom pin dimensions upfront speeds up the quotation and avoids compatibility issues after shipment.
Hydraulic Peel Grapple vs Orange Peel Grapple: What's the Difference?
In practice, these two terms describe the same attachment. "Orange peel grapple" is the more widely used name internationally, referencing the shape of the open jaws, while "Hydraulic Peel Grapple" describes the hydraulic drive mechanism behind the same design. Some suppliers also use "peel grab" or "scrap grapple" interchangeably.For buyers, this means search results and supplier catalogs under either name typically refer to the same product category. When requesting quotes, it's worth using both terms with your supplier to confirm you are comparing equivalent specifications, since minor differences in jaw shape or cylinder placement can exist between manufacturers even within the same general category.
Installation, Maintenance & After-Sales Support
Installing a Hydraulic Peel Grapple involves connecting it to the excavator's hydraulic auxiliary lines and mounting bracket, then testing the open/close and rotation cycles at low pressure before full operation. Changyu provides installation documentation with every order, and the technical team is available to support buyers remotely during commissioning.Routine maintenance is limited to a few recurring tasks:
• Greasing pivot points on a regular schedule
• Inspecting jaw edges and cylinder seals for wear
• Checking hydraulic hose connections for leaks after the first weeks of operation
For buyers placing their first order, Changyu also offers guidance on spare parts stocking, so distributors can support end customers locally without waiting on international shipping for common wear items.
