Hydraulic grabs for excavators are the core equipment of the multifunctional attachments of excavators, especially the lotus claw (also known as multi-petal grab). The lotus claw launched by YG is designed for complex working conditions, combining the high-efficiency grabbing ability of the hydraulic grab bucket with the durability of the rock grabs for excavators. Its unique multi-petal structure can easily handle the grabbing and sorting of loose or bulk materials such as construction waste, ore, scrap steel, etc., and is suitable for a variety of scenarios such as mines, ports, and demolition sites. Through the precise control of the hydraulic system, the lotus claw improves operating efficiency while significantly reducing labor costs.

Applications Of Hydraulic Grab Bucket
- Mining: Quickly sorting large pieces of ore (rock grabs for excavators), replacing manual crushing;
- Building demolition: Efficiently grab concrete fragments to reduce secondary crushing costs;
- Port logistics: Loading and unloading scrap steel and bulk materials, single operation efficiency increased by 40%;
- Environmental recycling: Classify and grab recyclables such as metals and plastics to support resource reuse.
A mining company in Senegal reported: “After using YG’s hydraulic grabs for excavators, the ore processing speed increased by 3 times and the equipment wear rate decreased by 25%.”
Hydraulic grab bucket Working Principle
The lotus claw is precisely controlled by a hydraulic drive:
- Power transmission: The hydraulic oil pump of the excavator delivers high-pressure oil to the grab cylinder;
- Grabbing action: The cylinder pushes the connecting rod mechanism to drive the multi-petal claw teeth to close/open;
- Load adjustment: The built-in pressure sensor provides real-time feedback on the grab force to prevent overloading;
- Adaptive design: The claw angle of the hydraulic grab bucket can be automatically fine-tuned according to the shape of the material to ensure a stable grip.
- This principle enables rock grabs for excavators to crush hard materials and maintain a high grab rate in loose environments.
Features of rock grabs for excavators
- High strength and durability: The overall heat treatment process extends the service life to more than 15,000 hours;
- Intelligent control: Optional remote control operation module to achieve precise operation 20 meters away;
- Fast switching: Universal interface adapts to mainstream brand excavators, replacement time <30 minutes;
- Safe and reliable: Double hydraulic locking device prevents accidental loosening, ISO 9001 certified;
- Energy saving and environmental protection: Energy consumption is reduced by 15% compared with traditional grab buckets, and operating noise is <80 decibels.
