Megatron VS Steel Rope
Megatron was the ruthless leader of the Decepticons, while Steel Grimace was the leader of the Dinosaur Faction. In the early days, Dino-Robots, including Grimlock, had been duped by Megatron to join the Decepticon camp, but later, because of the fact that they were saved by the Prime, Grimlock led the Dino-Robots back to the autobots camp. In terms of combat power, in the early stages of the Dinosaur Army, when they did not have the fusion function, they were slightly inferior to Hercules and the other hybrid Vajras. However, Wei Zhentian could send Hercules and the other hybrid Vajras to deal with the Dinosaur Army, causing the Dinosaur Army to be beaten up. However, the Fusion King Kong was helpless against the thick-skinned Dinosaur Army. As the plot developed, Steel Cudgel and the others created a powerful combination of King Kong and King of Calculation in the head of the Cosmic Monarch. In the Legend of the Shura King comic, the Dinosaur Army completed the combination and crushed Flying Tiger, Chong Yunxiao, and Chaos Panther in the battle (although the original creator did not acknowledge this comic). In the 2017 Power of Heaven Origin comic, the Dinosaur Army combined into Long Yanwang, posing a powerful threat to the Decepticons. However, there was no data to show that Megatron and Steel Grimace had a direct one-on-one battle, but Megatron was good at using strategies, such as he once bewitched the robot dinosaur to attack Optius Prime.

A novel like Ballet on a Steel Rope
National Code for Lifeline Steel Rope
Lifeline wire ropes have different national specifications for different application scenarios: 1. ** Selection criteria **: - For the lifeline with a bearing capacity of not less than 1 ton, the material shall be a metal steel core wire rope. The plating grade shall refer to the standard of the national standard (GB8918 - 2006), and the grade shall not be lower than Grade A. If the diameter of the wire rope obtained by calculating the bearing capacity of the combination of the clamp and the wire rope is less than 8mm, the diameter of the wire rope selected shall not be less than 8 mm. - In the installation of the lifeline for aerial operations, it is required to use a Galvanized Steel Rope with a diameter of no less than 12mm. It should be free of defects such as broken wires, broken strands, burns, corrosion, and serious distortion. 2. ** Scrap standard **: - The number of broken wires of the wire rope of the lifting machinery within a lay pitch should reach 10% of the total number of wires of the wire rope (such as the rope 6×19 = 114 wires, when the number of broken wires reaches 12 wires, it should be scrapped and replaced; such as the rope 6×37 = 222 wires, when the number of broken wires reaches 22 wires, it should be scrapped and replaced; for the wire rope composed of thick and thin wires, the number of broken wires is calculated as one for each fine wire, and 1.7 for each thick wire). - The steel wire shall be scrapped if the amount of wear or corrosion exceeds 40% of the original diameter. When it is less than 40%, the number of broken wires can be reduced and scrapped according to the regulations. The number of scrapped wires of the steel wire rope used for lifting hot metal or dangerous goods shall be half of the standard for the scrap of the steel wire rope used for general cranes. - In addition, when the diameter of the wire rope is reduced by 7%; when the whole wire is broken; when the wire rope has obvious internal corrosion; when the partial outer layer of the wire rope shows "cage" shape distortion; when the fiber core of the wire rope is twisted, bent, plastically deformed, the hemp core comes out, and the performance of the wire rope is affected by the high temperature of the arc, the wire rope should also be scrapped; when the whole wire strand is broken, the wire rope should be scrapped; When the diameter of the wire rope is reduced by 7% or more compared to the nominal diameter, even if no broken wire is found, the wire rope should be scrapped; the hemp core should be scrapped; the wire rope should be scrapped if there is obvious corrosion; the partial outer steel wire is elongated into a cage-shaped state; Mechanical damage due to the operation on the sharp projections, local wear due to the friction of the supporting structure, vibration of the wire rope between the head wheel and the drum, and fatigue fracture due to narrow wear (Working in too large a rope groove or working in too small a support groove will cause this problem), the wire rope is seriously worn, the fiber core is protruding, and the wire rope twisted in the same direction is seriously worn.(caused by friction between the intersecting points of the multi-layer wound wire rope), severe corrosion caused by the wire rope soaked in the water that has been treated by the clamp, almost no signs of damage on the surface but internal corrosion, complete disappearance of the gap between the strands, and typical broken wires caused by bending fatigue of the wire rope.(This kind of situation occurs mostly in the type of point-contact wire rope), broken wires between strands or rope cores (caused by the lack of rope core support, which is obviously different from the broken wires at the "top" of the strands), etc. should also be scrapped. 3. ** Rope clamp related specifications **: - In the section steel suspension, the nominal diameter of the wire rope shall not be less than 14, and the number of rope clips shall not be less than 3.(In case of special circumstances, when the load of the frame is large and the wire rope is required to participate in the force calculation, the nominal diameter of the wire rope and the number of rope clips shall be determined according to the calculation and the table). - In the overhanging operating platform, the nominal diameter of the wire rope should be determined according to the calculation. The diameter of the rope clamp should match the wire rope, and the number of rope clips should not be less than 4. - The distance between the rope clips is generally 6 - 7 times the nominal diameter of the wire rope; the direction of the rope clip is that the U-shaped bolt of the rope clip is buckled at the end of the wire rope (i.e. the end of the rope), and the clip seat is at the working section. All the rope clips are in the same direction and cannot be staggered. 4. ** Other requirements **: - During the installation of the lifeline for aerial work, the personnel engaged in the installation and removal of the lifeline must hold the valid certificate issued by the local government or the specialized agency. For the installation of the cross brace, one inclined rod should be buckled on the main column, and the other one should be buckled on the extended part of the small horizontal rod. The distance between the buckle at both ends of the inclined rod and the vertical rod node should not be less than 20cm. During the installation and removal, the lifeline must be hung with a red card and prohibited from being used. For all lifelines longer than 100m, in harsh environments or when multiple lifelines are needed in small areas, cushions shall be placed at the parts where the lifelines are in contact with the sharp edges of the steel beams to prevent damage to the lifelines; the lifelines shall be pulled inside the columns on the free surface and shall not be pulled outside. - In terms of lifeline-related tests, such as static load test: hang a 200kg heavy sandbag at the middle wire rope position and let it stand for 24 hours. It is required that the wire rope and the clamp are not bent or deformed, the wire rope is not broken, and the roof panel is not damaged; For impact test, hang an 80kg heavy sandbag at the middle wire rope position, and the free fall height is 2 meters. - In terms of wire rope slings commonly used in construction sites, the safety factor shall not be less than 6 times; when the end of the wire rope is braided and fixed, the length of the braided part shall not be less than 20 times the diameter of the wire rope and shall not be less than 300mm; the wire rope clamp shall be on the side of the wire rope, and the distance between the rope clips shall not be less than 6 times the diameter of the wire rope.
