[0044] Precision of lifting operation:

[0045] The extension hoist 6 of the device adopts a multi-lifting point design, which helps to balance and stabilize the goods, especially when lifting large or heavy goods. It can more accurately control the lifting and placement position of the goods. Compared with traditional equipment, this device can better maintain the stability of the goods when handling heavy goods, reducing damage caused by unstable lifting.

[0046] Labor cost saving:

[0047] The device is designed to be automated, making the lifting process more convenient and reducing dependence on manual labor. For example, the hoist support body 3 can automatically slide and adjust through the drive trolley 31 and the drive structure 34, reducing the complexity and labor intensity of manual operation, especially suitable for high-frequency and large-volume operations.

[0048] Diversified lifting tasks:

[0049] The device is not only suitable for traditional single-goods lifting, but also supports multi-point lifting when needed, especially for tasks that require lifting multiple large or heavy goods at the same time, providing higher flexibility and diversified operation capability.

[0050] Summary:

[0051] The advantages of the device are higher lifting efficiency, stronger stability, more flexible configuration, higher safety and adaptability. Compared with existing technology, it designs multi-head hoist and extension hoist, making heavy goods handling work faster, more accurate and safer, while reducing manual operation intensity and improving operation efficiency. These advantages make the device have obvious competitiveness in modern heavy goods handling.
