What is the hook?

hook block is an assembly to which a jack or crane hook is connected; It usually consists of a steel case that would mention a number of pulleys or pulleys that carry ropes or chains that facilitate lifting the load. Although it sounds unnecessarily more complicated, it would be impossible for a crane or jack to function efficiently and safely if the hook was simply connected directly to the rope and then lifted or triggered the system of crane boom and reel. The block of the hook allows a considerable amount of flexibility and safety when lifting operations as opposed to direct connection.

One of the most important functions of any block of the hook is to facilitate the free arrangement of rotation or rotating hook. When the loads are raised, it is often necessary to turn the load to place in a new place or avoid the hit of obstacles. A crane hook attached directly to the lifting ropes would cause the ropes to turn if the load was rotated from the original orientation. These had a number of side effects such as excessA stressful ropes and boom pulleys, creating unbalanced loads and causing the load to turn uncontrolled in an uncontrolled way when released. The block of hooks allows you to freely rotate the load without changing the orientation of the rope of the jacks.

This load rotation can be facilitated manually in the case of low, manageable loads or can be achieved by means of a power hook that can be remotely rotated by a crane or ground. This allows for a very controlled and accurate rotation and location of very large and cumbersome loads. Powered hooks also mean that into the rotation of the load that significantly increases the safety of such operations

The second main advantage of using the hook block is the use of multiple hoists. The rope used to lift the load is evaluated according to the overall evaluation of the crane. If one rope should be used, it would have to be extremely strong, which would cause a series of problemThey related to the design, construction and operation of crane. This would also create security problems because there would be no redundancy or security margins if the ropes were bound. The use of multiple ropes means that each length or autumn rope is much thinner than a single rope, the load is better distributed at the top of the boom or boom, and there is a redundancy system if the rope breaks.

The number of shores used in the crane hook block varies according to the intended use and evaluation of the crane and can range from two to eight or more positives. Hook blocks can also include peripheral devices such as load and scores that show load weight, adjustable clutch assembly for impact protection and extended hooks for specialized applications. All meet the basic function of allowing safe and easy loading of load and using thinner multiple lifting ropes for efficient and safe operation.
