When using electric gourds to transport slender components (such as square wood, steel pipes, steel grilles, etc.), the constitution is firmly tied and the balance of the component is very important. 1. When hanging the grille steel frame, hang the electric gourd near the side of the horizontal channel. Coscomb the main tendons and tied to 1/3 of the grille length. 2. When the transportation is over -limited, it cannot be transported more than one bundle. It can only be transported one at a time and bundle the cable to 1/3 of the length of the item. Increase friction to prevent items from falling off. The above two items must ensure that the items are vertical. 3. When the transportation limit allows materials, the following safety solutions are taken. (1) Multiple bundles should be bundled by a special person, and the hanging point must be centered to ensure that during the transportation process, the bundled items are at the level until the operation is completed. (2) You can put the items in the bucket, but you must be connected to the side of the bucket with the side of the bucket, and you cannot place it in the earthen bucket in the well entrance. (3) When transporting soft and long materials, the items must be tied into a plate.
