摘要： PROBLEM TO BE SOLVED: To form a construction device compact and light in a lifting device for constructing a bridge beam while moving on the bridge beam, set length of a wire rope between the bridge beam and the lifting device to the shortest possible, and adjust the bridge beam in a horizontal direction by micro-move of the lifting device in positioning the bridge beam to a tip part of an already constructed bridge beam. SOLUTION: A device comprises a main body 1 to move on an already constructed bridge beam 20 formed on a base 2 to be freely fixed on the already constructed bridge beam 20, and a frame 3 engaged to be relatively movable forward and back the base 2, and provided with legs 6, a hoist means 4 to suspend a bridge beam 21 to be connected to a tip of the already constructed bridge beam 20, and a moving means 5 to relatively move the base 2 and the frame 3 to each other, so by repeating relative motion of the frame 3 to the base 2, and relative motion of the base 2 to the frame 3 by lifting the base 3 from the already constructed bridge beam 20 by the legs 6, the main body is moved on the already constructed bridge beam 20, and after the base 2 is fixed to the already constructed bridge beam 20, the bridge beam 21 is positioned by micro-move of the frame 3 as relative move to the base 2.

摘要： PROBLEM TO BE SOLVED: To immediately stop turning, derricking, and extension/contraction of a boom simultaneously with operation of a high lift working base in emergency so as to improve safety, by providing an emergent stop device immediately stopping operation of the high lift working base and operation of a crane, in a crane provided with the high lift working base on the extreme end part of the boom. SOLUTION: In a crane in which an engine key 20 is inserted in a key hole provided on a console panel 30 in a driver's seat 2, an emergent stop device 19 is fitted to the part to be turned with a hand by a driver so as to be fitted form the outside spacedly from the part by a narrow gap. When and emergent stop button provided on a machine side operation board or a remote-operation board provided on a high lift working base is pushed, or the safety device of a load detecting means so as to generate an emergent stop signal, simultaneously with stopping motor-driven jacks as a balancing device of the high lift working base and a turning device, the driving means 21 of the emergent stop device 19 is actuated, and engine is stopped by rotationally moving the engine key 20. and hence operation of the crane is stopped.

摘要： PROBLEM TO BE SOLVED: To provide an elevator used for construction which is easily assembled, dissembled, and carried, by providing each floor door which is arranged on a stop floor of a building or others, and a fixing means which installs each floor door on the each stop floor, height of the building on a hoistway tower, and forming the hoistway tower so that it horizontally surrounds a carrier. SOLUTION: Each floor door 6 and a truss construction panel 16 which complements parts without the each floor door 6, are installed on U-shaped openings of a hoistway tower 4. Therefore, the each floor door 6 and a mounting hole in which a panel is installed are arranged on the both sides of the opening. As a result, the hoistway tower 4 is formed in the square pole shape with a hollow part, and a carrier 5 can rise and fall in the hollow part. By integrally forming the carrier 5, the hoistway tower 4, and the each floor door 6, a man-hour of assembling and dissembling work in a construction field is reduced, and by reducing facilities of the construction field and actual working hours of workers which are needed for assembling and dissembling work of the construction work elevator, working efficiency is improved.
