South america forklift energy storage module

How can a forklift with electric lifting device improve energy management?

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.

How efficient is a hydraulic forklift?

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.

What are the energy flows in a forklift?

Analysis of the energy flows in Forklift There are many energy flows in the forklift, Fig. 2 depicts the energy flows from the power forklift toward the walking motor and the wheels through transmission system, which is one of the main flow of energy. The other is from power forklift toward lifting motor and ball screw device.

How does a forklift lift system work?

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.

What is the system structure of forklift with ball screw device?

Fig. 3. System structure of forklift with ball screw device. In this system, vehicle controller is used to detect the signal of the operation device and the state of supercapacitor. Then, it sends a control signal to the first clutch and the second clutch.

Why is a forklift a waste of energy?

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.
