Types and Internal Structure of Forklifts

First of all, the power system is the heart of a forklift, which can be classified into two main types: internal combustion power and electric power. Internal combustion forklifts are equipped with fuel engines, featuring strong power and durable performance, suitable for outdoor and heavy-duty working environments. Electric forklifts adopt battery and motor drive systems, including AC and DC motor structures. They are low-noise, zero-emission and energy-saving, making them ideal for indoor and closed warehouse operations.

In recent years, lithium-ion battery structures have gradually replaced traditional lead-acid batteries, greatly improving the working efficiency and service life of electric forklifts. Thirdly, the transmission and chassis structure supports the overall operation of the forklift. There are three mainstream transmission structures: mechanical transmission, hydrodynamic transmission and hydrostatic transmission. Mechanical transmission has a simple structure and low maintenance cost. Hydrodynamic transmission runs smoothly with strong overload resistance. Hydrostatic transmission features stepless speed regulation and flexible operation, which is common on high-end automatic stackers. The chassis system includes the frame, drive axle and steering axle. The counterweight structure at the rear of the body balances the front load to ensure driving stability, which is the core structural feature of counterbalance forklifts and stackers.

In conclusion, every internal structural type of a forklift has its unique advantages and applicable scenarios. The perfect coordination of power, lifting, transmission and control systems enables forklifts to adapt to diverse logistics handling needs. Understanding forklift internal structures is essential for improving operation efficiency, ensuring safety and conducting daily equipment maintenance.
