Circular design is most efficient considering handling of load as load gets shared through out the structure,this is not possible with any other possible shape such as triangular rectangular as there are vertices present in them were load will get concentrated and will lead to breakage .

What is Procedure of inspection the eot crane?
1. check the hook without load like safety latch of the hook, Sheave for free of jam, Break& distortion of the hook. 2. Check the wire rope any defects like cuts, Distortion and Lubrication condition. 3. Check the structure of the crane like any cracks. 4. Check safety interlocks & limit switches. 5. Check leakages of the reducers & its abnormal noise. 6. check all the functions of the crane with and without load.

What prevents the hook block from contacting the jib pulley on a tower crane?
The hook block is prevented from contacting the jib pulley on a tower crane primarily by the crane's design, which includes a limit switch or safety mechanism that stops the block at a predetermined height. Additionally, the rigging configuration and the length of the hoist line are designed to ensure adequate clearance between the hook block and the jib pulley during operation. Proper operation practices and maintenance also play a crucial role in maintaining this clearance.

How does the load change on a crane hook?
The load on a crane hook changes based on several factors, including the weight of the lifted object, the angle of the load, and any dynamic forces during lifting or lowering. As the crane hoists or lowers the load, the tension in the hook will fluctuate due to these variables. Additionally, if the crane swings or experiences wind, the load's effective weight on the hook can vary, impacting overall stability. Proper calculations and monitoring are essential to ensure safe lifting operations.
