<p>PROBLEM TO BE SOLVED: To provide a piping installation carriage device with which it is not necessary to lay rails in a sheath pipe, the inclination of a carriage including pipes can be avoided, savings of a material cost and an installation cost and the reduction in the installation lead time can be realized and the installation work is facilitated, when pipes for wiring cables are pulled into the sheath pipe embedded in the ground for the installation. SOLUTION: A carriage 11 which is loaded with pipes 6 for wiring cables and transferred, when the pipes 6 are pulled into a sheath pipe 1 embedded in the ground, has ball wheels 24 which enable the free rotation of the carriage 11. A pendulum function which makes the carriage 11 horizontal in a direction perpendicular to a progressing direction is added to the carrier 11. The pendulum function suppresses the rotating moment in a direction perpendicular to the advancing direction of the carriage 11. With this constitution, the inclination of the carriage 11 including the pipes 6 can be avoided, when the pipes 6 are pulled into the sheath pipe 1, so that a group of pipes 6 can be installed horizontally in the longitudinal direction in the sheath pipe 1.</p> |
