The structural, kinematics and kinetostatics analysis of the lifting and empting mechanism from the small containers in the loading area of the machines used to collect and transport the domestic waste is studied in this paper. Special calculus procedures, created by the authors, were used for the study of the mechanism, from the kinematic and kinetostatic point of view. These calculus procedures are specific to each structural group and the mechanism realization is based on those structural groups. The obtain data were graphically represented in diagrams to give an objective image over the kinematic and kinetostatic parameters of the mechanism. Keywords: refuse machines, bin, mechanism, kinematics analysis, kinetostatics analysis INTRODUCTION Refuse machines for collect and transport of the waste materials, from the production point to the ecologic waste deposits, have as main working parts the following: proper collecting bin, waste feed hopper, lifting and empting equipment of the pre-collecting recipients (bins, small containers), compaction mechanism, hydraulic drive equipment for charging and discharging [12]. The mechanisms for lift and discharge the small pre-collecting containers on the receiving hoppers of the refuse machines are, usually, articulated bar mechanisms. The role of those mechanisms is to lift the pre-collecting container in vertical position, up to the feeding hopper of the refuse machine, thus the wastes stay in the container, and then to fold it thus the waste fell in the machine feed hopper. They are, generally, planar mechanisms with articulated bars drive by hydraulic cylinders. Kinematics and kinetostatics study of these mechanisms can be easily done if these mechanisms are decomposed in simple modules which can be study independently, from kinematic and kinetostatic point of view. The authors have realized calculus procedures which were reunited in a main program in order to study those mechanisms. The dimensions of mechanism elements are based on the results of the study, thus those elements can be produced with minimum quantity of material and can withstand the loads imposed by design.
