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 in detail, hoping to help the staff perform accurate operations.

(1) Tips for accurately stopping the hook: When lifting, the hook must stop accurately above the lifted object. It is necessary to use a cart or a trolley for "alignment". The big car is relatively easy, while the small car is more complicated. You need to test the hoisting to observe the stress of the sling wire rope. If the wire rope on one side of the hook is stressed first and becomes tighter, while the wire rope on the other side of the hook is later stressed, it means that the trolley deviates from the center of gravity of the weight. The trolley should be moved to the side where the wire rope is stressed first. When the stress on both sides of the wire rope is equal, the trolley is in the correct position.

(2) Tips for accurate lifting and lowering: When lifting and lowering heavy objects, be sure to prevent the heavy objects from swinging violently to avoid collision accidents 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 lift the hook slowly; when the weight of the heavy object is unknown, turn the controller handle to the stop to lift. If it cannot be lifted, it means it is overloaded or the crane is malfunctioning. When the heavy object is lifted to the designated position, you should pay attention to observe the smooth descent.

(3) Tips for smooth operation When the crane is lifting heavy objects, the heavy objects should be kept stable and not swing greatly; the number of starts of the crane should be appropriately controlled. Repeated starting and braking will cause impact and cause the heavy objects to swing, thus affecting the smooth operation of the operating mechanism. It will also lead to crane fatigue, which is detrimental to the life of electrical equipment and parts of the mechanism.
