本発明は農作業等に用いられるトレーラ装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a trailer device used for agricultural work and the like.
従来、この種のトレーラ装置として実開昭55−
22251号公報のものが知られている。
Conventionally, this type of trailer device was developed in 1983.
The one disclosed in Publication No. 22251 is known.

倒の危険性があるという不都合を有している。[Problems to be Solved by the Invention] However, the trailer frame has a considerable frame length, and since the trailer frame is connected to the traveling aircraft so that it can horizontally turn and bend, it is connected at one point.
When the loading platform is tilted upward, the center of gravity of the cargo on the loading platform moves backwards, making the horizontal state of the trailer frame unstable, causing the front side of the trailer frame to not only lift up but also cause damage if the loaded weight is larger. This has the disadvantage that there is a risk of falling.
