Trial Production of Line Braking Device for Line Hauler.

A line braking device applying a load to a line hauler was built in the laboratoly. Experiments were conducted to evaluate the mechanical characteristics of a line braking device. The results showed that the line braking device applied a load to the line hauler firmly, safely, and continuously. It was possible to reproduce the actual loading situation, approximately except for the rapid fluctuation in the tension. Thus the initial objective was satisfied. A testing set for line haulers including the line braking device could be widely introduced to study and training using fishery machine for lines.
