摘要： PROBLEM TO BE SOLVED: To calculate the life of a wire rope in consideration of damage to the wire rope due to a shock load. SOLUTION: A cargo is lifted up and down via the wire rope and a sheave over which the wire rope is looped by paying out the wire rope from a drum and rewinding the wire rope to the drum. The presence or absence of an actual load of the cargo and a shock load exceeding the actual load by a predetermined amount is detected based on load data of the cargo outputted from a load cell provided in the sheave (step 33). When the presence of the shock load is detected, a value obtained by multiplying a life subtraction value obtained when the presence of the shock load is not detected by a correction coefficient having a value exceeding 1 is subtracted from an estimated life (step 34), and a new estimated life (the remaining usable number of times) of the wire rope is displayed (step 35).

摘要： PROBLEM TO BE SOLVED: To obtain a long-life roll by electrostatically sticking numberless resin particles which are negatively charged to the surface while rotating a rolling roll, making the parts to which the resin particles are not stuck into fine recessed parts by etching and, by removing the resin particles, forming a fine irregular pattern, the top end of the projecting parts of which is planar and excellent in wear resistance, on the surface of the roll. SOLUTION: The rolling roll 1 is made into a grounded voltage and rotated, the resin particles 11 which are charged into a negative polar and jetted with a powder coating device 10 are electrostatically stuck to the rolling roll 1. The surface of the rolling roll 1 to which the resin particles are stuck is inductively heated with an electromagnetic induction coil and the resin particles 11 are melt-welded and fixed. By etching the surface of the rolling roll 1, the recessed parts are formed in the parts to which the resin particles 11 are not stuck and, when the resin particles 11 are removed by washing with a solvent, the irregular pattern consisting of fine projecting parts and fine recessed parts is formed. Because lubricity is secured and frictional property is also secured by this irregular pattern, the generation of burning and flaws or the like are prevented.

摘要： PROBLEM TO BE SOLVED: To remove a defect of a roller table in a short time by interposing an elastic body between a steel plate and a polishing plate in such an interval as corresponding to the roller pitch of the roller table and closely sticking the polishing plate to a roller surface. SOLUTION: A polishing plate 2 of a defect removal device for a roller table mounted on a continuous roller table is pushed against a roller 5 by the weight of a steel plate 1 so that, when the roller 5 is rotated, the roller 5 surface is polished by the polishing plate 2 by the frictional force between the polishing plate 2 and the roller 5 so as to remove the defect. That is to say, the frictional force of the polishing plate 2 for polishing is generated by the rotation power of the roller 5 and the load of the steel plate 1. An elastic body 3 is arranged between the steel plate 1 and the polishing plate 2 in such an interval as corresponding to the pitch of the roller 5 so as to improve the adhesion between the polishing plate 2 and the roller 5. This constitution can broaden the adhesion area between the polishing plate 2 and the roller 5.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of respective work following of a plurality of conveyance vehicles on the whole by allocating the conveyance vehicle which can reach a cargo receiving point in a conveyance command the earliest for the execution of a conveyance command, from among the conveyance commands which are within an upper limit number set in each block and have the high priority in order. SOLUTION: In 'scheduling', an AGV calculator executes 'pretreatment' 39 first. Next, in 'allocation processing' 40, each conveyance command of conveyance command table to be allocated is assorted into blocks to which From skid belongs in each conveyance command (S1). An upper limit value of the conveyance command for block is set (S2). The conveyance commands are arranged and changed according to the priority order, only the conveyance command equivalent to command upper limit number for each block is left in each block table, from among the conveyance commands having the higher priority, and the other conveyance commands are erased (S3). AGV is allocated to each conveyance command of conveyance command table to be allocated (S4). The AGV calculator executes 'allocation outputting' (S5).

摘要： PROBLEM TO BE SOLVED: To enable highly accurate rolling hardly having the change of wear coefficient caused by the wear of rolling rolls by coating recessed parts with metal for preventing foreign matters from sticking after forming the recessed parts of a specified depth on the surface of a roll. SOLUTION: After forming a recessed and projection part having the depth of recessed parts of 5-100μm and the flat area ratio of projecting parts of 10-80% is formed on the surface of the rolling roll 1 by electrolytic etching, the recessed parts are coated with the metal 5 for preventing foreign matters from sticking such as metallic chromiunm and a nickel-phosphorus alloy. Thus, the fine ruggedness 4 in the bottom part of the recessed part 2 is flatened and, also, by coating the projecting part 3 with the metal 5 for preventing foreign matters from sticking of hard metal, wear resistance of the projecting part 3 is improved and the durability of the roll 1 is raised. Because high draft rolling is enabled in the early stage of rolling, the accuracy of rolling is raised. Furthermore, dents or the like of the rolled steel strip are reduced and the quality and yield are improved.

摘要： PROBLEM TO BE SOLVED: To surely prevent the adhesion of a foreign matter such as scum to a carrying roll by coating a recessed part on the carrying roll surface with a resin. SOLUTION: The recessed part 2 of a carrying roll 1 is coated with a resin 5 to cover and smooth fine irregularities 4 formed on the worked surface (low part or side wall) of the recessed part 2. To form protruding and recessed parts by chemical etching, for example, a resist is applied to the carrying roll surface (whole surface) to sensitize and harden the part corresponding to a protruding part, and the resist in the non-sensitized part (non-hardened part) corresponding to the recessed part 2 is washed and removed. The resist removed part is chemically etched by the contact with an etching solution to form the recessed part 2. Thereafter, the resin is sprayed thereon to cover the recessed part 2, and the resist of the protruding part 3 is then removed. Thus, a foreign matter such as scum is hardly captured by the fine irregularities 4 on the bottom part of the recessed part 2, and the side wall of the recessed part is also smoothed by the resin, so that the adhesion of the foreign matter such as scum thereto can be prevented.
