Two-Rope Mechanical Grab Buckets: (Holding & Closing)
APR Bright Industries designs the two-rope mechanical grabs for cranes equipped with dual-drum winches-one for holding and one for closing.
Designed with high-tensile , wear-resistant steel (Hardox®), optimized to minimize dead weight while maximize the payload of crane. Our grabs are manufactured for heavy-duty cycle in the most demanding industrial environments, and reduce the cycle times and operational costs up to 25%.
Core Product Configurations
Specialized Grabs Designs for Diverse Material Handling
Two-Rope Mechanical Clamshell Grabs
Ideal for handling bulk material includes sand, coal, fertilizer, and grains. Our grabs are featured a precision-fit design to avoid material spillage and confims a 95-100% fullness degree.
Two-Rope Orange Peel (Cactus) Grabs
Follow the ISO, CE marking, reinforced with Hardox 500, and optimized multi-tine(polyp) designed for deep penetration’s to handle irregular material such as metal, rocks, pig iron etc.
Designed for High-Abrasion Performance
Material: Designed with high-quality material including high-tensile, wear-resistant(HARDOX) to increase the durabiluty and decrease the dead weight.
Mechanism: Secure material handling operation while one rope hold the grabs in position and other rope operate the opening and closing cycles.
Capacity: Customized design solution as per demands of industries from 0.5m3 to 20m3 to suit your specific crane’s safe working load (SWL).

Technical FAQs
Q: What is the main purpose of a Two-Line (Two-Rope) Grab?
Ans: Two-rope mechanical grabs bucket designed for shipyards, docks, steel plant and other industries to dig, load, and unload bulk material efficiently. Our grabs offers robust and noise-free operation compared to hydraulic grabs.
Q: Can these grabs be customized for high-density materials?
Ans: Yes, APR Bright Industries offers customized grab bucket geometry and closing forces to handle the density material like rocks, sand, iron ore, clinker etc.
Q: Can I use these grabs for abrasive materials like iron ore?
Ans: Yes, our grabs is equipped the wear-resistant steel and hardened pins (220–260 BHN) to ensure the grab withstands the friction of iron ore, debris and crap material.
Clamshell vs. Orange Peel Grab: Comparative Technical Analysis
| Feature | Two-Rope Clamshell Grab | Two-Rope Orange Peel Grab |
|---|---|---|
| Design | 2-shell bucket closing vertically | 4–8 curved tines closing inward |
| Best For | Free-flowing bulk materials | Irregular, bulky, scrap materials |
| Typical Materials | Coal, sand, grain, ores | Scrap metal, rocks, debris |
| Grip Type | Traps material between shells | Encircles material from all sides |
| Penetration | Good in loose materials | Excellent in compact/heavy piles |
| Spillage Control | Moderate | High |
| Cycle Speed | Faster | Slightly slower |
| Maintenance | Lower (simple structure) | Higher (more moving parts) |
| Cost | Economical | Higher investment |
| Ideal Industries | Ports, mining, bulk terminals | Scrap yards, recycling, demolition |
Clamshell = Speed & Efficiency for Bulk Materials
Orange Peel = Power & Control for Irregular Loads
