摘要： PURPOSE:To prevent the generation of malfunction part by a crane and to enlarge the working range of the crane by placing a revolving superstructure at the top floor after constructing the body top floor, lifting and removing a mast and the base using the revolving superstructure, and then overhauling and removing the revolving superstructure in a tower crane installed in the inside of a building site. CONSTITUTION:After constructing the body top floor, a crane bearing beam 6 is installed on the body top floor and reverse climbing is conducted by a climbing device 3 to put a revolving superstructure in the crane bearing beam 6. Secondly, the top floor mast 1a is removed by the revolving superstructure. Subsequently, the crane revolving superstructure 4 is moved laterally, and the remaining mast 1 is lifted up with the climbing device 3 and the base 2 and removed using the revolving superstructure. After that, the revolving superstructure 4 is overhauled and removed. By this arrangement, even if the crane is placed during a long period of time, the generation of malfunction part is avoided and the working range of the crane can be enlarged.

摘要： PURPOSE:To facilitate the shifting and removing operations by installing the body part of a slide base frame on the lower side of the turning wheel receiving board of a crane body and installing a plurality of supporting legs onto the basic part in demountable manners by a basic part and connecting a crane body shifting mechanism onto one side of the frame. CONSTITUTION:After a frame assembly A of a building is assembled ud to a rooftop floor, a crane body 2 is shifted to remove a mast 1, and at this time two shift receiving supporting beams 30 are laid in parallel in the horizontal state, keeping a prescribed interval, setting the mast 1 interposed in the direction for shifting the body 2. Then, a crane body shifting mechanism 4 is operated. In other words, a shift reaction force receiving supporting girder 42 is fixed by a catch-holding fixing mechanism 43 by using a hydraulic unit 14 mounted onto the turning board 3 of the body 2, and a hydraulic cylinder 45 is operated in a prescribed stroke, and then a slide base frame 20 slides on the upper surface of the beam 30 by the supporting leg 23 part, and the body 2 shifts. Therefore, a climbing mechanism 10, mast 1 etc. at the original positions are disassembled successively and removed by the crane.

摘要： PURPOSE:To effect an efficient oxidation of the iron (II) compound in underground water for removal as iron (III) hydroxide and make the aeration treating facility compact, by providing such a structure as to bring the underground water pumped up under pressure into contact or reaction with oxidizing material in a mixed and diffused state in an aeration treating zone. CONSTITUTION:The underground water pumped up by a pressure water pump 2 and the oxidizing material fed from a piping 12 are caused to flow in a mixed and diffused state into contact or reaction with each other while maintaining the water pressure in an aeration treating zone 4. This method converts the iron (II) compound dissolved in the underground water into an insoluble iron (III) hydroxide which is then separated and removed from the water to be treated by a solid-liquid separation method in a settling tank 10.
