In the manufacturing industry, logistics transit and other links, the workshop often requires vehicles to undertake material handling tasks for a long time, especially for the handling demand of 3.5 tons. Recently, in a conventional production food processing workshop, we conducted a three-day real-life test of a long-endurance 3.5-ton lithium-ion forklift that focuses on long-term continuous operation.
The measured workshop area is about 6,000 square meters, the working environment is mainly flat cement floor, the local area has a slight slope, the slope does not exceed 3 degrees, the daily handling of goods is mainly food raw material packaging and work in progress turnover box, single pallet cargo weight is usually between 2 tons and 3.2 tons, close to the rated load limit of 3.5 tons, the daily operation time is stable at about ten hours, the middle is arranged with two short breaks of about ten minutes for the driver, and the vehicle is not arranged for centralized charging.
On the first day of the actual test, we fully charged the battery of this long-range 3.5-ton lithium-ion forklift to the displayed full grid state, and then started the vehicle according to the normal operation process of the workshop. The whole process was operated by two drivers with more than three years of electric forklift driving experience in the workshop. After the first day of operation, the vehicle power showed that there was about a quarter of the remaining power, and there was no power attenuation. Whether it was loading goods uphill on a slightly sloping section, or turning in a narrow passage and stacking up to a three-meter-high shelf, the operation was kept smooth, and the steering flexibility did not change much compared to when it was empty.
The measured scenes and cargo weight on the second and third days were basically the same as on the first day. After the operation on the third day, the vehicle power showed that the remaining power was close to the zero limit. The cumulative operation time was about 29 hours, and the cumulative number of cargo pallets was about 780. During the actual measurement period, all the basic functions of the vehicle were running normally without any trouble prompts. According to the driver's feedback, the seat back height of this long-endurance 3.5-ton lithium forklift is adjustable, and the fatigue of long-term driving is relatively low. The braking response of the vehicle is also relatively timely, and the overall operation experience is good.
