Analysis and Solution for Resolving Hydraulic Hose Failures in Backhoe Loaders

This project describes about the case study of hoses in field issues and means to reduce the warranty claims of hose failures. The study was done by analysing how and why the hose fails in the Backhoe loaders and explores solution for rectification. In backhoe loaders, hoses plays a vital role, as only with the help of hoses, the backhoe loaders will be able to move the cylinders to operate the bucket and the hoe. To ensure optimum hose performance, we should have pressure or vacuum characteristics of the system, operating temperature, flexibility required in the application, types of medium being transmitted and environmental condition with which the hose exterior must withstand. This project covers a major area to exhibit the exact application of root cause analysis to diminish product defects. This project work also discusses implementation and solution aspects in product area by instructing the suppliers to rectify regarding the field failure hose. The hoses will be constructed with different number of braids. Based on flow requirement, hose size will be selected.
