Double Cable Double Flap Mechanical Grab

The Double Cable Double Flap Mechanical Grab is a bulk cargo handling system widely used in ports, docks, and mining facilities. Primarily designed for handling loose materials such as coal, ores, grains, and sand, this equipment features dual-rope (steel wire rope) drive technology and a double-flap structure with two jaw plates. Its core advantages include high efficiency, durability, and strong adaptability to various working conditions.

Jaw plate (claw valve): Usually made of high-strength welded steel plate, it is divided into two parts. The shape is designed according to the characteristics of the materials (e.g., flat mouth, shell shape, toothed shape, etc.) to ensure grabbing efficiency and sealing.

Supporting rod mechanism: Connects the jaw plate and the upper bearing beam, transmitting the opening and closing force through the connecting rod to control the jaw plate's movement.

Upper beam and lower beam: The upper beam connects to the lifting wire rope, while the lower beam connects to the opening and closing wire rope. The coordinated movement of the two beams controls the grab's opening and closing.

Pulley set: Installed on the head of the grab, it guides the wire rope and transmits power.

Steel wire rope (double cable):
Hoisting rope: Responsible for lifting the entire grab.
Closing rope: Controls the opening and closing of the jaw plate, working in coordination with the lifting rope to complete material pickup and unloading.

• Open state: The closing wire rope is relaxed, the lifting wire rope is under tension, and the jaw plate remains open due to its own weight and the action of the support rod.
• Material grabbing: The grab descends onto the material pile. The closing wire rope tightens, pulling the lower bearing beam upward, which drives the jaw plate to close and cut into the material.
• Lifting and transportation: Both cables are tightened synchronously to keep the jaw plate closed, transporting the material to the target position.
• Unloading: The closing wire rope is relaxed, and the jaw plate opens under the force of material gravity or its own weight to complete unloading.

Efficient operation: Independent control of the dual cables enables fast action, making it suitable for frequent loading and unloading.

Strong adaptability: Jaw plates can be replaced (e.g., toothed, thickened) to handle different materials (e.g., clay, large ores).

Durability: The sturdy steel structure and wear-resistant design ensure a long service life.

Easy maintenance: Wear-prone parts such as pulleys and wire ropes are standardized for easy replacement.

Technical parameters are fully customizable to meet customer needs.

Note: It can be customized according to customer needs.
