Design of a garbage compacting tractor trailer body design

Abstract

Sri Lanka local government authorities commonly use four wheel tractor trailers for collection and transportation of Municipal solid waste collected daily. There are many environmental issues in using open tractor such as bad smell, over spillage of garbage, risk of diseases etc. In addition tractor trailers are frequently damaged while unloading at uneven surfaces in dumping yards. The fully covered compactors are available at Colombo Municipal Council and several other local government authorities in Sri Lanka. Most of them have been received under foreign aid. They are sophisticated vehicles and convenient for garbage collection activities. It can transport higher load safely and without having environmental consequences stated above. There are several types of compactors available in the world such as front loading, rear loading and side loading compactors. In Sri Lanka, rear loading compactors are commonly used. This project aims to manufacture garbage compacting unit witch can be mounted on the tractor trailer. The compactor will be rear loading, closed type body with hydraulic compacting system. The available pump of the tractor is used for the hydraulic circuit. Several experiments were carried out to get loads and other measurements required for the design. The body made out of steel sheets and U-channels available in the local market and hydraulic components have to be obtained from its local suppliers. . Manual calculations and computer software packages of "SolidWorks" and "COSMOS Works" were used for the design of the compactor body. Total cost for this modification is estimated to Rs 1,000,000/=. It is rather low cost compared to the performance of the imported compactors.
