林用架空索道导向滑车“h_2”值的确定

DETERMINATION OF“h_2”VALUE FOR LEAD-BLOCKS USED IN CABLEWAYS IN FOREST OPERATION

本文从理论上和实践上第一次论证了林用架空索道导向滑车的滑轮选择系数“h_2”为14,从而为导向滑车的设计和制造提供了新的可靠依据。

'h2' is a coefficient for calculating the minimum pitch diameter of rope blocks in the selection of suitable lead-block. Through theoretical and practical means, the 'h2' value was found as 14 for the leadblock used in cableways in forest operation.As a result,a new reliable 'h2'for designing and manufacturing of a lead-block might be based upon.
