Forklift
Overview
A forklift is an industrial vehicle that lifts and transports cargo using forks. It handles loading, unloading, and transport in warehouses, ports, factories, and construction sites, establishing itself as key equipment that determines logistics efficiency and productivity. Recently, eco-friendly and advanced technologies such as electrification, automation, and hydrogen fuel cells have been incorporated, rapidly changing the paradigm of industrial vehicles.
Main Content
Definition and Structure
A forklift consists of the body, mast, forks, counterweight, drive unit, steering unit, and hydraulic system. The mast is a structure that lifts cargo vertically, and the forks support pallets and cargo. The counterweight supports the load and prevents overturning. The operator performs precise loading and unloading work even in narrow spaces through forward/reverse movement and hydraulic operation.
Types
- Counterbalance type: The most common form, it lifts cargo at the front and maintains balance with weight at the rear.
- Reach type: The mast moves forward and backward, enabling work in narrow aisles, and it is widely used for warehouses.
- Electric forklift: Powered by a battery, it is suitable for environments where exhaust gas is a concern, such as indoors and in frozen warehouses.
- VNA very narrow aisle type: Enables high stacking in very narrow aisles.
- Side loader: Special equipment that lifts and transports long materials from the side.
Power Sources
Traditionally, diesel, LPG, and gasoline engines were used, but recently electric forklifts equipped with lithium-ion batteries are rapidly spreading. Electric forklifts have no exhaust gas and low noise, making them advantageous for indoor logistics. Hydrogen fuel cell forklifts have short charging times and can operate for long periods, and pilot adoption is expanding in large logistics centers.
Safety and Regulations
As forklifts are equipment that handles heavy objects, safety regulations are strict. In Korea, qualification requirements such as the Forklift Operator Certification (지게차운전기능사) and safety training are required, and at workplaces, safety devices and aisle management are important to prevent overturning, collision, and pinching accidents. Major safety devices include seat belts, rear cameras, warning sounds, speed limits, and tilt angle limits. Internationally, ISO 3691, the EU Machinery Directive, and others apply.
Industrial Role
Forklifts are used in a wide range of industries, including material supply in manufacturing, warehouse management in distribution, container unloading at ports, and material transport at construction sites. As logistics automation progresses, unmanned forklifts linked with AGVs and AMRs have also appeared, contributing to 24-hour operation and labor cost reduction.
Latest Trends
The key keywords in the forklift market for 2024-2025 are electrification, automation, and strengthened safety. The transition to electric forklifts is accelerating due to falling lithium-ion battery prices and the expansion of charging infrastructure, and major manufacturers are competitively introducing high-voltage, high-efficiency batteries and rapid charging technology. In addition, as the integrated operation of autonomous forklifts and logistics robots spreads, the construction of smart logistics centers is in full swing. Hydrogen fuel cell forklifts are being demonstrated mainly at ports and large warehouses. On the safety side, the introduction of AI-based collision prevention, driver monitoring, and remote control systems is increasing, and regulatory authorities in each country are strengthening emission reduction and workplace safety standards.
