Evaluating the energy storage capabilities of forklift actuator

Abstract

Energy saving in construction and logistics is a topical and open issue today. Forklifts are one of the main self-propelled means of mechanization of warehouses, in which the effect of energy recovery can be applied. This is due to the peculiarity of such systems that operate in overclocking and braking modes. The purpose of this work is to study the energy consumption in the drive system of the loader based on the analysis of the sequence diagram of its operation for given sections of movement. Methodology. The equation of traction balance of a wheeled machine is used to estimate energy consumption at given sections of the load movement. Determination of the kinematic parameters of the loader system with the load is determined from the condition of maximum traction. Results. The mass characteristics of the system, speed of movement, characteristics of the road surface contribute to the formation of the energy return by the system of the loader in the process of its braking. Increasing operating speeds will have a positive effect on energy savings in energy storage systems. Analysis of energy consumption during the operation of the loader shows that in the process of its operation you can effectively store from 30 to 70% of energy. Originality. This study uses an engineering assessment approach that will be useful for practical applications in the design of such systems. Practical value. In this study, the sequence diagram of the energy consumption of a forklift when working with loads of 2000 kg, 1000 kg and 500 kg is essential. The sequence diagram method is simple and can therefore be easily implemented in forklift control systems to enable energy recovery systems.
