Time study analyses of skidding with cable-grapple skidder Equus 175N

Abstract

This time study assesses time consumption and productivity of EQUUS 175N cable-grapple skidder. Within the time study 34 work cycles were measured, and 9 snapshots of work day were taken. In the study was used methods of continuous time study. The result show that the overall time consumption of the work cycle of the monitored cable-grapple skidder is influenced by skidding diatance and number of logs in a load. Non-operation times of the skidder operator shift represent 27 % with the highest pert taken by the machine defaults repair. The mean gross production rate of the monitored skidder was 5,85 m3.h-1. The aim of the present study was to: (i) assess the impact of production factors on the time consumption of individual partial work operations of EQUUS 175N cable-grapple skidder; (ii) find out and compare the productivity of monitored skidder.
