摘要： PURPOSE:To reduce the cost of carrying facility as well as make the transportation of long parts in narrow area easier by a method in which a hanger is set through a turnable (around vertical shaft) wire guide on the tip of crane boom, and a loading base provided on the outside of scaffold is vertically moved by crane winch. CONSTITUTION:A turnable (around vertical shaft) wire guide 5 is set through a turnable (around horizontal shaft) supporter 14 on the center of the horizontal boom 3b of a tilting boom 3. A hanging wire 7 from the winch is connected to a traverser 9 through the boom 3 and the guide 5. In carrying long parts in narrow area, the guide 5 is turned through 90 deg. and passed through the boom 3. A loading base 27 is also provided through a guide 26 for vertical movement for the scaffold 23 and moved vertically by a wire 7 to carry tools to each stair, thereby saving the cost of facilities. The tools and materials can thus be carried along at low cost easily.

摘要： PURPOSE:To improve efficiency of water absorption by providing a sleigh-like grounding material and a rotor for winding hose on a body frame furnished with a water absorption device, and by having the hose wound up and withdrawn by means of the progress of the body through a compressor linked to an elastic hose. CONSTITUTION:A sleigh-like grounding body 2 being attached on each side of a body frame 1 in its cross direction, a mat-like water absorption member 3 is formed on the grounding body 2. On the upper part of the frame 1, a water absorption device 7 that is composed of a catchment tank 5 and a vacuum pump 6 is formed, while a rotor for winding hose is attached to each post 14 on the right and left, and one edge of an elastic hose 16 is connected with the rotor 15 as well as the other with a compressor 17. The body 1 being held by the grounding body 2, as the gas is compressed from the compressor 17 to let the body progress, the hose 16 is wound up and is withdrawn, during which the water on the concrete surface is inhaled by the pump 6. In this way, water absorption can be made effective.

摘要： PURPOSE:To improve efficiency of water absorption by providing a net whose mesh is smaller than the particle size of a component of concrete on the lower surface of a mat member in which plural of water absorption passages extending along the side of the lower surface are formed, and by having water absorbed through a communicating passage communicating with the water absorption passage. CONSTITUTION:Plural water absorption passages 3 are formed in a mat member 1, being extended along the lower surface of the mat, and the water absorption passages 3 are connected with a communicating passage 4. On the lower surface of the member 1, a metallic net 2 whose mesh is smaller than the particle size of a component of concrete is provided. One edge of an inlet pipe 5 formed in the center of the member 1 is connected with the communicating passage 4, and the other edge with a catchment pipe 7. A water absorption device is composed of the member 1, the pipe 7, a catchment tank 6, and of a vacuum pump 8, which is driven to attract the water on the concrete surface. Effective water pumping can thus be executed.
