The excavator orange peel grapple—commonly referred to as an orange peel grab, within the industry, as a multi-tine grapple—is a hydraulically driven attachment mounted to the front end of an excavator. Its unique multi-tine structure (typically comprising 3, 4, or 5 tines) allows it to open and close much like an “orange peel,” thereby enabling the efficient grasping of materials with irregular shapes. Because it resembles a blooming lotus flower when fully extended, it has also acquired the vivid nickname: the “excavator lotus claw.” This attachment is primarily utilised for the loading, stacking, sorting, and handling of bulk or irregularly shaped materials—including scrap steel, scrap iron, waste paper, waste plastics, stones, timber, and construction debris. When equipped with such a grapple, an excavator demonstrates unparalleled flexibility and efficiency in performing these operations.

Working Principle of the YG Excavator Orange Peel Grapple
The core working principle of the excavator orange peel grapple is “hydraulic-driven opening and closing + multi-lobe coordinated clamping.” The entire process requires no complex operation and works in conjunction with the excavator.
- Equipment Installation: Connect the excavator orange peel grapple to the excavator’s boom via the connecting bracket, securing it firmly. Simultaneously connect it to the excavator’s hydraulic system, adjusting the opening and closing flexibility of the grab to ensure normal operation. It is compatible with existing hydraulic interfaces of the excavator with a claw, requiring no additional modifications.
- Material Clamping: Operate the excavator to move the grab above the material. Through the excavator’s hydraulic control system, drive the hydraulic cylinder to extend, opening the grab. Once aligned with the material, control the hydraulic cylinder to retract, closing the grab. Utilising the friction between the teeth and the material, the material is firmly clamped, suitable for clamping blocky and loose materials.
- Material Handling: After clamping the material, operate the excavator to move it to the designated position, adjust the height and angle of the gripper to ensure material stability and prevent it from falling off. During handling, the hydraulic two-way lock can fix the gripper position to prevent accidental opening and closing.
- Material Unloading: After reaching the designated position, control the hydraulic cylinder to extend, causing the gripper to open and smoothly unload the material. After unloading, adjust the gripper position to prepare for the next clamping operation. The operating mode can be quickly switched to adapt to different materials.

7 Main Features and Functions of the YG Excavator Orange Peel Grab Bucket
- Multi-Jaw Powerful Clamping; Secure Material Handling: Featuring a symmetrical 4-to-6-jaw “orange-peel” design, this grab offers a wide clamping range. The serrated tips on the jaw heads enhance friction, and when combined with a high-pressure hydraulic drive, the maximum clamping force reaches up to 80 kN. This ensures a firm grip on lumpy and bulk materials—such as ore, scrap steel, and slag—preventing slippage and ensuring high operational safety.
- Broad Compatibility and High Versatility: Adaptable to a wide range of excavators weighing between 6 and 30 tons—whether small or large—the unit allows for rapid installation and commissioning without the need for additional equipment modifications. It is fully compatible with standard excavators (including those already equipped with claw attachments) and is suitable for a diverse array of engineering applications.
- Convenient Hydraulic Control; High Operational Efficiency: Utilising a high-pressure hydraulic control system, the opening and closing speed of the jaws can be steplessly adjusted for flexible operation. This enables rapid material clamping, handling, and unloading, with a single-lift capacity ranging from 1 to 5 tons. Operational efficiency is boosted by over 80% compared to traditional manual handling methods.
- Wear-Resistant and Durable; Long Service Life: The jaws feature a dual-protection structure comprising high-strength structural steel and wear-resistant liners. This design offers exceptional resistance to abrasion and impact, allowing for long-term operation in dusty, heavy-load environments. Furthermore, the hydraulic system boasts superior sealing performance—being both water- and dust-proof—which minimises malfunctions and extends the overall service life of the equipment.
- Comprehensive Safety Protection; Secure Operations: Equipped with advanced safety devices—such as hydraulic overload protection and bi-directional hydraulic locks—the unit prevents damage to the hydraulic system caused by overloading and safeguards against accidental jaw opening or closing that could result in material spillage. The jaw design strictly adheres to safety standards, featuring smooth, burr-free edges to prevent injury to operating personnel.
- Lightweight Design; Energy-Efficient Operation: Employing a lightweight structural design, the unit weighs 15% less than comparable products in its class. This reduces the load on the excavator, lowers fuel consumption, and simultaneously enhances the excavator’s operational agility, making it ideally suited for work in confined or narrow spaces.
- Customizable to Meet Specific Requirements: The grab can be customised—including the number of tines, gripping range, and wear resistance level—to align with specific client operational needs. This allows it to accommodate the gripping requirements of various materials—such as ore, scrap steel, and timber—while also adapting to specialised operational scenarios for excavator-mounted “lotus claw” attachments.

Frequently Asked Questions About YG Excavator Orange Grab Buckets
A1: YG excavator orange grab buckets are available in various models and connection methods, compatible with excavators of all brands and tonnages—from small to large. Before purchasing, please provide the specific model and tonnage of your excavator so we can recommend the most suitable grab bucket for your equipment.
A2: The number of claws (e.g., 3-claw, 4-claw, 5-claw configurations) affects the grab bucket’s adaptability and gripping force when handling materials. Generally, the more claws, the better it can wrap around irregularly shaped materials and provide a more stable gripping force. For example, a five-claw grab bucket performs excellently when handling loose materials (such as scrap metal).
A3: The key to extending the service life of an orange grab bucket lies in proper operation and routine maintenance. This includes regularly inspecting pins and hydraulic cylinders to ensure timely lubrication, avoiding overloading, using genuine parts, and regularly inspecting and replacing worn parts promptly.
