Sampling shoots from tall canopies with a balloon-hoisted cutting device
Australian Forestry, 1991Summary A cutting device hoisted by a helium-filled balloon was developed for sampling leaves or other material in tall tree canopies. The apparatus was found to perform well when used to obtain leaves at a height of 30 m in a Eucalyptus grandis canopy. Full details of the design and construction of the balloon and cutter are given.

Application and performance evaluation of a lifting device with alternating rotation hoist
2016 IEEE/SICE International Symposium on System Integration (SII), 2016There exist vertical long ropes that need periodical inspection for infrastructure maintenance. Development of lifting devices along with the ropes is demanded for steady observation at human-unreachable positions. The lifting device based on alternating rotation hoist has been proposed for carrying inspection devices to the target level. This research
