I believe that many operators are worried about how to operate the hook accurately. Today, the hook manufacturer will introduce some tips for hook operation to you in detail, hoping to help the staff perform accurate operations.

 (1) Tips for accurate hook parking: When lifting, the hook should be accurately parked above the heavy object to be lifted. It is necessary to use a large cart or a small cart to "correct". Large trucks are relatively easy, while small trucks are more complicated. You need to try to lift to observe the stress of the sling wire rope. If the wire rope on one side of the hook is tighter first, while the wire rope on the other side of the hook is looser afterwards; it means that the car deviates from the center of gravity of the heavy object, and the car should run to the side where the wire rope is first subjected to force. When the wire ropes on both sides are equally stressed, the car is in the correct position.

 (2) Tips for accurate lifting and falling: When lifting and falling heavy objects, they must prevent heavy objects from swinging violently to avoid collisions and impact on the crane. When lifting a heavy object, keep the hook and the center of gravity of the heavy object on the same vertical line and slowly lift the hook; when the weight of the heavy object is unknown, pull the controller handle to the stop for lifting. If it cannot be lifted, it means that the overload or the crane has failed. When the heavy object is lifted to the designated position, pay attention to the steady decline.

(3) Skills of smooth operation When cranes lift heavy objects, the heavy objects should be kept stable and not swing significantly; appropriately control the number of starts of the crane, repeated starts and braking will produce impacts, causing heavy objects to swing, thereby affecting the smooth operation of the operating mechanism, and also causing crane fatigue, which is not conducive to the life of electrical equipment and components of the mechanism.
