Study On The Cab Layout Design And Operating Efficiency Of Log Harvester

Log harvester is a set of construction machinery, it gathers fellling, lopping and bucking in one. This machinery can improve the cutting efficiency dramatically relative to the conventional human cutting. Cab is an important part of log harvester. Drivers contact cab directly, so, a well designed cab can not only make drivers working comfortably, but it also can improve the cutting efficiency significantly. Consequently, it's essential to study on cab designing for forestry harvesting and on the influnce on cutting efficiency.This paper is divided into two parts. One part is to study the layout of log harvester(the layout mentioned in this paper involves both arrangement and design); the other part is study on the efficiency of log harvester. There must be exist some connections between the two parts, because a well designed cab could improve the efficiency of log harvester. The technical basis of cab layout is Human Factor Engineering, scientific application of Human Factor Engineering would create a good relation among human, machine and environment. The layout of log harvester cab is different from normal automotive cab, which depends on their different functions. The working process of log harvester is primarily through the command of manipulator motion, the working range of manipulator is relatively wide so that the motion of body is not so wide. The design of cab should concern about the control equipment of manipulator motion, so, this paper primarily studies on the arrangement of seat and control equipment. The technical basis of efficiency of log harvester is fundamental industrial engineering. Fundamental industrial engineering is a subject which is concern about technique and efficiency. This article includes program analysis, operation analysis, motion analysis and work measurement in order to reform unreasonable working process and improve working efficiency. The working efficiency is the key point of this paper.The seat and control equipment of log harvester cab are the main object discussed in this paper. Using the theory of Human Factor Engineering to design, make use of solidworks software drawing three-dimensional layout design of cab, then based on the theory of fundamental industrial engineering to study on the working instance of log harvester, analyz the working efficiency of log harvester precisely in theory and lay a foundation for the manufactering and debugging of prototype. At the same time, shorten the development cycle efficiently and reduce the development cost.
