We also proposed energy management strategy development of a forklift with electric lifting device to achieve a system that can be controlled easily with different speeds up and down, and at the same time, recover as much energy as possible in the downward movement and braking, which used supercapacitor as the energy storage system.
Not only lifting and lowering of goods, but also speeding up and braking are typical running characteristics of forklift, which waste a great deal of energy. In addition, the transmission efficiency of hydraulic system is very low , which is a great waste of energy in the course of the fork up or down.
We use the supercapacitor as the energy storage system, and maximum recovery efficiency of the electric system is 46.72%. In recent years, the forklift is facing two challenges energy saving and environmental. However, the hydraulic forklift has low transmission efficiency and energy efficiency.
This study proposed and implemented telescopic fork transmission mechanisms for automated storage and retrieval system (AS/RS) stacker cranes in the smart warehouse model. The strict initial requirements of the system comprise high payload, high positioning accuracy, low taping deformation, high acceleration transmission, and low noise.
The lifting system is controlled directly with an electric motor drive instead of pump. First, we analyzed the working condition and energy flows of the forklift and proposed an energy recovery system for forklift. Second, we built the system model including supercapacitor model, vehicle model and the simulation model in AMESim.
