Hand pulled haws are driven by pulling the zipper tape, and when pulling the zipper tape, it is required to pull vertically, as this can minimize resistance to the greatest extent possible, while diagonal and horizontal pulling can cause a certain degree of wear and tear on the hand pulled haws. However, there is a problem with vertical pulling, which is that the operator must stand below the hand hoist.

Please note that the area below the chain hoist is not a safe zone. Once the brake system of the chain hoist fails, the operator is highly likely to be injured by a sudden falling heavy object. To avoid such situations, 360 ton rotary chain hoists have emerged. The biggest feature of this type of chain hoist is that the cover of the zipper strip can rotate 360 degrees, allowing the zipper strip to be pulled in any direction.

Before operation, the operator only needs to twist the cover, align the hole of the hand zipper with a specific direction according to actual needs, and then pull the chain. In this way, the operator does not need to stand under the hoist and can perform diagonal or horizontal pulling operations on one side, greatly improving the safety of the hand pulled hoist lifting operation.

Before pulling the chain block vertically, it is necessary to perform a self-locking sensitivity test on the chain block to ensure its safe operation.
