Hydraulic Grapple: Precision-Engineered Attachment for Heavy-Duty Material Handling
Publish Time: 2025-05-29 Origin: Site
RAY Hydraulic Grapple is designed for excavators, offering a robust solution for professionals requiring secure and efficient material handling across diverse industries. Built with safety, durability, and adaptability at its core, this attachment is quickly gaining traction in forestry, construction, and agricultural sectors.
1. 360-Degree Rotation for Unmatched Maneuverability
The Hydraulic Grapple features an unlimited 360-degree rotatable swing bearing system, enabling operators to position the grapple precisely in any orientation without repositioning the excavator. This capability reduces cycle times by up to 30% in complex tasks like navigating tight urban spaces or uneven terrain. The system’s reinforced bearing design ensures smooth rotation under heavy loads, withstanding over 10,000 hours of continuous operation in field tests.
2. EATON Motor Delivers Reliable Power
Equipped with a high-performance EATON brand motor, the Hydraulic Grapple provides consistent torque and stability across demanding applications. EATON’s industry-leading motor technology—known for its low starting pressure (≤10 bar) and high efficiency (≥92%)—ensures reliable operation even in extreme conditions. The motor’s integrated thermal protection system prevents overheating, extending service life by 25% compared to standard motors.
3. Advanced Valve System Enhances Safety & Durability
The attachment incorporates a triple-valve safety mechanism (oil flow control, balance, and safety valves) to optimize hydraulic performance. The balance valve maintains equal pressure distribution during operation, while the safety valve automatically disengages under overload conditions, reducing cylinder wear by 40%. Additionally, the brake valve mitigates inertia-related risks by providing instant stopping power, tested to withstand 1.5x the rated load without failure.
Key safety features include:
• Automatic pressure compensation during sudden stops
• Burst-proof hydraulic hoses with 4x safety factor
• Reinforced grab arms with NM400 wear-resistant steel (360–420 HBW hardness)
4. Comprehensive Model Range for Versatile Applications
Seven models are available, precisely matched to excavator tonnages from 3–40 tons. Each model undergoes rigorous load testing (120% of rated capacity) to ensure structural integrity:
Model | Excavator Tonnage | Opening Width | Key Applications |
RHG03 | 3–5 tons | 1,280 mm | Small-scale wood/sugar cane handling |
RHG04 | 5–8 tons | 1,371 mm | Municipal greening, orchard maintenance |
RHG06 | 9–16 tons | 1,539 mm | Medium forestry/logistics |
RHG08A | 17–23 tons | 1,648 mm | Stone handling with wear-resistant iron blocks |
RHG08 | 17–23 tons | 2,492 mm | Large-diameter logs, industrial debris |
RHG10 | 24–30 tons | 2,492 mm | Heavy construction, port operations |
RHG14 | 30–40 tons | 2,492 mm | Mining, large-scale demolition |
Ideal for contractors handling wood, stone, or agricultural materials, this attachment combines German-engineered precision with rugged durability. For detailed specifications or a site demo, visit www.rayattachments.com or contact us.
