Product Description

Dredging grab is mainly composed of bucket, sling, opening and closing mechanism and other components, is a kind of mechanical grab, often with two-rope or four-rope cranes, lifting ship supporting underwater dredging and salvage operations. Due to the high viscous resistance of underwater debris, the material requirements are high.

1. Improve work efficiency and reduce cost;
2. Rigid structure, sturdy and durable;
3. Strong gripping ability: capable of gripping sediments of various hardnesses and particle sizes;
4. Wide adaptability: can work under different water depth and underwater terrain conditions;
5. Flexible operation: the gripping depth and position can be adjusted according to the needs;
6. Can design and produce eligible grabs according to different scene requirements;
7. OEM & ODM accept.

1. Dredging of harbours and waterways: to clean up silt deposits, such as silt, slate sand and stone materials, to ensure the safety of navigation for ships.
2. Water conservancy engineering: used for dredging of rivers, reservoirs, etc., to improve the flood control, irrigation and power generation capacity of water conservancy facilities.
3. Marine engineering: on the construction of offshore oil platforms, submarine pipeline laying and other projects, the cleaning of submarine sediments.




According to the number of flaps are divided into double-flap grabs and multi-flap grabs.
1. Double-flap grab grabs general bulk materials, such as coke, coal, grain, yellow sand, bulk fertilizer, mineral powder, etc.:
2. Multi-valve grab grabs large materials or irregularly shaped bulk materials, such as grabbing garbage, stones, pig iron blocks, slag, waste steel and wood.
The lifting and opening/closing of the grapple is controlled by four wire ropes, the grapple is smooth and can be adapted to different working environments and working characteristics, and the bucket flap has a solid structure, good abrasion resistance, high strength, and strong gripping ability.
