DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tropical rain forest and the like, which is erected between a crown portion and the ground so that it can easily ascend and descend, and observes and measures the environment and the ecosystem of animals and plants in the crown portion. The present invention relates to a canopy elevating device suitable for carrying out the method.

[0002]

2. Description of the Related Art In tropical rainforests, the distribution of animals and plants that make up the ecosystem is concentrated in the canopy because of the extremely high height of trees, high density and high air humidity. In forest research, it is necessary to focus on the crown, and it is necessary to attach various types of observation and measurement equipment to the crown and observe and measure the crown by shooting aerial images with a balloon. Have been. But,
With these methods, there is a natural limitation in observing the biological activities and ecosystems of animals and plants in the crown, and long ladders and iron pipes are erected on the tall trees, and the climbers climb the crown regularly and observe directly. Although it is necessary, erection of long ladders and iron pipes as described above has many difficulties,
In practice, it is difficult to observe the crown directly for a long time on a regular basis, and observation research on the crown of a tropical rain forest has been delayed and has become an unknown area.

[0003]

In order to directly and periodically observe the crown of a tropical rain forest or the like, it is necessary to easily carry out ascent / descent and observation / measurement on trees as described above in a safe operation. However, the conventional elevating means using a long ladder or an iron pipe has many difficulties in erection, and there is a problem that the elevating and observing the work is dangerous. In order to promote such canopy observation research, it is desired to develop a canopy elevating system that can safely elevate and regularly observe and measure regularly for a long time.

[0004] The present invention has been developed in view of the above-mentioned situation, and its object is to enable easy installation between the crown of the tree and the ground, thereby improving the workability as well as the elevating and lowering performance and workability.
