Tension Detection Device for Circular Chain Cargo Transportation Ropeway in Mountain Orchard

Abstract:

For studying effects of different combinations of influential factors including payload variations, tension locations, loading approaches and motoring frequencies the circular chain cargo transportation ropeway imposes on the driving-chain in mountain orchards, a related device added to the ropeway system was designed to detect real-time dynamic variations for driving-chain tensions. The experimental results indicated that effects from the other three factors on the hoisting chain tension were obvious except for that from the motoring frequency. While the mechanical operator was adjusted to various locations, exclusively at the start and at the terminal, differences of mean tension variations were obtained ranging from 105.929N to 164.641N under different payloads. In addition, when the mechanical operator was adjusted to the commencing point, through either balanced loading or unbalanced loading approaches, mean tension variations were obtained ranging from 1165.351N to 1425.864N and 1140.500N to 1435.353N with related variation coefficients from 0.115 to 0.139 and 0.155 to 0.227, respectively.
