Abstract

<P>PROBLEM TO BE SOLVED: To provide a moving truck capable of properly traveling even when a traveling environment changes. <P>SOLUTION: Plural kinds of single trucks having traveling performance suitable for a specific traveling environment are prepared. The single truck suitable for the traveling environment travels while mounting a single truck not suitable for the traveling environment on its deck. Therefore, the single trucks can travel by changing traveling and mounting each other according to traveling environments. For example, in a traveling environment where wasteland or a step exists, a flat ground traveling truck 1 is mounted on a deck 6 of an all-terrain traveling truck 2. When the traveling environment is a flat ground, the all-terrain traveling truck 2 is mounted on a deck 4 of the flat ground traveling truck 1. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a mobile carriage for carrying a load.

  In general, a moving carriage adapted to the traveling environment is used for carrying a load. For example, a wheeled traveling cart is suitable for moving on flat ground, and a crawler traveling cart is suitable for traveling on stairs, steps, and wasteland. In this way, mobile trolleys having excellent running performance in a specific running environment are properly used according to the running environment to be used.

  However, since the conventional mobile carriage has only a single traveling system according to the traveling environment, for example, when the traveling environment is both flat and rough, a traveling vehicle with a wheel traveling system is used. When used, it cannot be applied to wasteland. Further, when a crawler traveling type moving carriage is used, there is a problem that the traveling speed on a flat ground becomes slow.

  An object of the present invention is to provide a movable carriage that can travel properly even when the traveling environment changes.

  According to a first aspect of the present invention, there is provided a mobile trolley having a plurality of types of single trolleys having a traveling performance suitable for a specific travel environment and having a loading platform, and the single trolley suitable for the travel environment is not suitable for the travel environment.
