The roller belt conveyor system is the process used in different industries to carry heavy loads from one place to another place with ease. Now-a-days, most of the companies are using heavy conveyor systems which tend to consume more power. Heavy assembly system also causes problems due to maintenance of critical components and results in increased man power and time consumption, which is not helping industries in attaining profitable growth. Material processing is an integral part of the industry and contributes a significant proportion of the total power supply. Material processing includes different types such as lifts, conveyors, etc. out of which conveyors are most useful and less time-consuming systems for the continuous movement of materials in industries. Belt conveyor is widely used for the continuous transportation of different equipments with better efficiency and strength. It is important to reduce the energy and energy costs of material handling. Therefore, this process is based on improving the efficiency of energy of belt conveyors, because these are the main reasons of this system that consume energy. This detailed study focuses on the optimization of critical parts like belt, rollers, roller shafts, frame, c- channels, brackets and by using different materials such as belt, roller and analyze it to minimize the assembly’s weight without changing its structural strength with the help of proper finite element model using software like CATIA. This paper also provides brief information on redesigning of critical parts of roller belt conveyors used in the industries for reducing the weight and power consumption. This paper also provides information about Roller belt conveyor system and different materials used in the system.

The main objective of this study is to assess the application of Lean Manufacturing in the companies adopting Lean management in order to improve its effectiveness, in addition to develop a track for other companies planning to adopt Lean management. This study explored key literature resulting in the development of a new model of application. Moreover, a special questionnaire developed as tool for gathering information gapping the bridges toward the effective application and problem solving. Additionally, the newly designed model and tool were used in a case study to assess the application in one of the leading Jordanian manufacturing companies. Descriptive statistics were used in this study, the study sample included (125) participant. Moreover, SPSS software was used in the data analysis. The results showed that the general arithmetic mean of sample answers on the statements which evaluates the effective application of Lean Manufacturing, has reached (3.203) of (4) with standard deviation of 0.725 representing high degree of estimation. This success is justified by satisfying the critical requirement of application.
