Single Rope Hydraulic Radio Remote Controlled Clamshell Grab Bucket

Product introduction:

I. Definition and Key Features

The remote-controlled grab is an innovative tool designed to integrate seamlessly with single-rope cranes, leveraging wireless remote control transmitters for its operation. Eliminating the need for external power sources, it incorporates an internal rechargeable battery that manages the opening and closing of the grab through the manipulation of solenoid valves. This advanced grab automatically closes upon the ascension of the hook over a material pile and, uniquely, can open at any point in mid-air with instant halt capabilities, vastly enhancing operational efficiency.

II. Structure and Operating Principle

The remote-controlled grab typically comprises several core components: an upper beam assembly, a sliding seat assembly, a lower beam assembly, the bucket body, brace rods, and hydraulic cylinders. Among these, the cylinder's barrel and piston rod are connected respectively to the lower beam assembly and sliding seat assembly. When cargo capture is initiated, the grab wire is released, allowing the weight of the sliding block to depress the piston rod into the cylinder. Here, the remote control activates the solenoid valve, closing the hydraulic system's fluid path, locking the sliding seat in place. The hoisting wire then lifts, enabling the grab to secure the cargo. Conversely, for cargo release, the remote control again triggers the solenoid valve, opening the hydraulic fluid path. This action permits the sliding block to withdraw the piston rod, pushing against the upper beam and thereby opening the grab to release the cargo.

III. Advantages and Applications

Energy Efficiency and Productivity: The remote-controlled grab boasts remarkable energy savings, requiring only minimal pulse electricity to operate its solenoid valves, far outperforming traditional grabs in terms of energy consumption. Moreover, its ability to open at any height shortens operational cycles, thereby elevating overall work efficiency.

Safety and Reliability: Attached directly to the crane without additional accessories, the remote-controlled grab minimizes potential failure points. Additionally, its multi-stage buffered opening mechanism significantly reduces the impact on both the grab and crane during unloading, ensuring heightened safety standards.

Ease of Operation: Equipped with a wireless remote control, operators can effortlessly manage the grab's opening and closing, significantly diminishing physical labor and enhancing operator comfort.

Versatility in Applications: Widely adopted across industries such as shipping, port operations, railway stations, factories, and mining, the remote-controlled grab serves as an ideal solution for handling bulk materials like coal, mineral powders, bulk fertilizers, and yellow sand, showcasing its immense versatility and value.
