2. Description of the Related Art In a tropical rain forest, the distribution of the plants and animals that make up the ecosystem is concentrated in the canopy due to the extremely high tree height and dense aerial humidity, and other factors. In the forest research, it is necessary to focus on the crown of the tree, and it is considered to attach various observation and measurement equipment to the crown, and to observe and measure the crown by shooting an aerial image with a balloon. Has been done. But,
With these methods, there is a limit to the observation of animal and plant bioactivity and ecosystems in the crown.Therefore, long ladders and iron pipes are erected on such tall trees, and climbs to the crown regularly for direct observation. Although it is necessary, there are many difficulties in erection of long ladders and iron pipes as described above, which is dangerous work,
In fact, it is difficult to observe the canopy directly for a long time on a regular basis, and the observational study of the canopy of the tropical rainforest has been delayed and has become an unknown area.

[0003]

In order to directly and regularly observe the canopy of a tropical rainforest, it is necessary to easily carry out the elevation, observation and measurement on the tree in a safe operation as described above. However, the conventional elevating means such as a long ladder or an iron pipe has many problems in erection, and there is a problem in that elevating and observing it is a dangerous work. In order to promote such observation and research of the canopy, it is desired to develop a canopy raising / lowering system that can safely ascend / descend and periodically observe and measure directly for a long time.

The present invention has been developed in view of the above situation, and its object is to make it possible to easily erect between the tree crown and the ground, and to improve workability as well as lifting performance and workability. It is intended to be provided as an environment-friendly canopy lifting device that does not hurt trees, etc.
