Comparison of three-wheeled and four-wheeled lithium-ion forklifts in narrow alleys, suggestions for the use of narrow alleys
Narrow lanes are typical spatial characteristics of storage-intensive scenarios. Reasonable selection of suitable lithium-ion forklifts is the key to improving operation efficiency. Next, compare the two types of vehicles from several dimensions, and give practical selection suggestions.
First look at the turning radius, which is the core indicator of narrow roadway suitability. Three-wheeled lithium-ion forklifts usually use a drive wheel steering design, with front-wheel load-bearing auxiliary steering or a drive wheel independent steering structure. The overall turning radius is relatively small. Some models can even complete in-situ steering or a very small radius U-turn in a space of about twice the body width, which has obvious advantages in ultra-narrow roadway scenarios with a channel width of less than 2 meters. Four-wheeled lithium-ion forklifts generally use front or rear wheel steering. Due to the distribution of four wheels, the turning track is more stable, but the minimum turning radius is usually larger than that of three-wheeled models with the same load, which is more suitable for conventional narrow roadways with a channel width of more than 2 meters.
Secondly, the load-bearing and stability are analyzed, and the load-bearing and stability of the two are also different. The structural characteristics of the three-wheeled lithium-ion forklift make it perform well when driving in a straight line and steering with light loads, but when the heavy load is quickly turning and passing through uneven ground, the stability will be slightly weaker, and the load range is usually concentrated in about 1 ton to 2 tons. The four-wheeled lithium-ion forklift has four wheels to support, a larger ground area, and a more uniform distribution of the center of gravity. Whether it is driving in a straight line or steering, the stability is higher, and it can cope with some slightly uneven ground. The load range generally ranges from 1 ton to 3 tons, and even a larger load range is available. It is more suitable for scenarios with heavy loads or high stability requirements.
Looking at the operation experience and maintenance costs, the driving wheel structure of the three-wheeled lithium-electric forklift is relatively simple, the maintenance involves fewer parts, the cost is usually low, and the steering operation feels lighter, which is suitable for beginners to get started quickly. The steering and suspension system of the four-wheeled lithium-electric forklift may be more complex, and the maintenance cost is relatively higher, but some models are equipped with auxiliary steering functions, and the operation experience is constantly being optimized.
Finally, recommendations for the use of narrow roadways are given. If the width of the storage channel is less than 2 meters, and light-load fast handling is the main one, a three-wheeled lithium-electric forklift can be given priority. If the channel width is more than 2 meters, there is a need for heavy-load handling or high requirements for ground adaptability, it is recommended to choose a four-wheeled lithium-electric forklift.
