摘要： PROBLEM TO BE SOLVED: To prevent the damage to a new trolley wire in the replacement work of a trolley wire. SOLUTION: A road/track working vehicle 1 has a vertically lifting type first lifting device 21 on a vehicle body 3. A placing base 25 is mounted to the upper part of the first lifting device 21, and a vertically lifting type second lifting device 30 and third lifting device 40 are provided on both sides in the vehicle body lateral direction of the upper part of the placing base. A first workbench 31 and a second workbench 41 arranged with a specified clearance 81 in the lateral direction of the vehicle body are provided at the respective upper parts of the second lifting device 30 and third lifting device 40. A first connecting plate 33 and a second connecting plate 46 swingable in the vertical direction are pivotally connected to the inner peripheral edge parts of work floors 32, 42 on the facing side of the first workbench 31 and second workbench 41. When the first connecting plate 33 and second connecting plate 46 are swung into a horizontal state in the state of the respective upper faces of the work floors 32, 42 being positioned flush with each other, the clearance 81 is covered in a plane state with the first connecting plate 33 and second connecting plate 46, and the first workbench 31 and second workbench 41 form one workbench.

摘要： PROBLEM TO BE SOLVED: To try to offer much weight saving, keep a sliding contact surface at the lower surface of each slider completely in an identical plane, reduce local abrasion over each slider by weakening impact against a pantagraph, and furthermore enhance insulating characteristics. SOLUTION: A suspended wire is connected with the ends of both the reams of insulators in a space between adjacently connected movable brackets B and B, and each trolley wire T is connected with both the ends of an insulating rod 1 which is made of resin while being located down-below the reams of insulators. Two sets of sliders where the ends of each long and each short slider are connected with each separator 8, are faced to each other alternately in relative length so as to be fixed to the insulating rod 1 with bolts 7 at bent base parts, and the sliders are suspended from the suspended wire by means of two suspending rods 9 in the vicinity of the bolts. The free ends at four places of the respective sliders are hanged down from the tip end parts of the horizontal main pipes of movable brackets by means of the other four suspended rods 10. Besides, a groove is provided for the lower surface in the longer direction of the insulating rod 1, and the side walls of the groove are to be split by a plurality of deep cuts alternately provided to the right and left.

摘要： PROBLEM TO BE SOLVED: To provide a connecting structure between a stanchion and a horizontal pipe in a structure facilitating prefabrication and work execution at a construction site and improving external design. SOLUTION: This connecting structure 6 between a stanchion 2 and a horizontal pipe 4 in a structure 1 comprises the stanchion 2 of circular cross section; a pair of holding pieces 7, 10 formed of aluminum alloy extruded shapes to hold the stanchion 2 from the right and left sides in a specified position; bolts 16 and nuts 18 for connecting end flanges 9, 12, coming in face contact with each other, of a pair of holding pieces 7, 10 and clamping the respective holding pieces 7, 10 to the stanchion 2, a vertical flat face 14 previously provided on the outside of the holding piece 10, and a horizontal pipe 4 jointed at one end to the flat face 14 by welding W. One end of the horizontal pipe 4 is previously jointed to the flat face 14 of one holding piece 10 by welding W, and the other holding piece 7 is fixed to the holding piece 10 by the bolts 16 and nuts 18, holding the stanchion 2 in between at a construction site. The connecting structure 6 can thereby be obtained rapidly, in few man-hour.
