Dismantling a tower crane is a complex and carefully orchestrated process that requires skilled personnel and adherence to safety protocols. Tower cranes are commonly used in construction projects to lift heavy materials and equipment to great heights. Here's an overview of the steps involved in dismantling a tower crane: **Planning and Preparation**: Before dismantling begins, a detailed plan is developed. This plan considers factors such as crane type, height, load capacity, site conditions, and weather. The crane operator and a team of skilled workers, including riggers and technicians, are involved in the dismantling process. **Removing Loads**: The crane's hook or hoist is used to lower any remaining loads or equipment from the crane's hook block. **Dismantling the Boom**: The boom (the horizontal arm of the crane) is disassembled section by section. This is done by attaching a tagline to each section and guiding it down as it's detached. A smaller auxiliary crane, such as a mobile crane, might be used to assist in removing boom sections safely. **Removing the Counterweights**: The counterweights, which provide stability to the crane, are removed one by one using the crane's hoist or an auxiliary crane. **Dismantling the Mast Sections**: The mast sections, which are the vertical components of the crane, are disassembled from the top down. This is typically done by removing bolts and pins that connect each section. A climbing frame might be used to facilitate safe access for workers as they dismantle the mast sections. **Lowering the Slewing Unit**: The slewing unit, which allows the crane to rotate, is carefully disconnected and lowered to the ground using a separate lifting device. **Dismantling the Jib**: If the crane has a jib (an additional arm that extends from the boom), it's disassembled using a similar process to that of the boom. **Dismantling the Base and Supporting Structure**: Once the upper components are removed, the crane's base and supporting structure are dismantled. Mobile cranes or other lifting equipment might be used to help with the removal of larger sections. **Transport and Storage**: The dismantled components are carefully loaded onto trucks for transport to a storage facility or the next construction site where the crane will be needed. **Site Cleanup and Restoration**: After the crane and its components are removed, the site is cleaned up, and any traces of the crane's presence are restored. Throughout the dismantling process, safety is of paramount importance. Procedures are followed to ensure the stability of the crane during disassembly, prevent accidents, and protect both the workers and the surrounding environment. Additionally, local regulations and industry standards play a crucial role in guiding the dismantling process. It's important to note that the specific steps and equipment used for dismantling a tower crane can vary based on the crane's model, design, and the conditions of the construction site. Therefore, only trained and experienced personnel should perform crane dismantling operations.
If SLI is in operating condition then sLI itself will indicates that whether load is in safe mode. But if SLI is not working then one must be considered 40 % factor of safety of crane SWL and in SLI working condition it will be considered 20 % of its SWL.

WRONG ANSWER below. Ships by tradition are not given male names and are always referred to with female names and pronouns. It was considered bad luck to give a male name to a ship, but on the other hand women were also not allowed to board a ship.
The gantry is a platform with support towers. This extra support is normally used for a travelling crane. The gantry also allows the crane to carry a very heavy load.
