In the field of warehousing and logistics, forklifts are indispensable handling equipment, and the requirements for forklifts vary significantly under different working conditions. As a low-temperature operation scenario, cold storage has special requirements for the performance of forklifts. There are many differences between cold storage lithium-electric forklifts and ordinary electric forklifts in actual use.
Differences in environmental adaptability
Ordinary electric forklifts are mainly designed for normal temperature environments. When entering low temperature scenarios such as cold storage, they will face many adaptation problems. The conventional batteries they use are greatly reduced in activity at low temperatures, and the electrolyte fluidity inside the battery becomes poor. Not only does the charging and discharging efficiency decrease, but it may also fail to start normally. At the same time, the seals, hydraulic oil and other components of ordinary forklifts are not made of cold-resistant materials. In low temperature environments, problems such as hardening cracking of seals and sticky cards of hydraulic oil are prone to occur, which affects the normal operation of the equipment. The cold storage lithium-electric forklifts are designed for low temperature working conditions. The batteries are made of low temperature resistant batteries, and with a special low temperature battery management system, they can work stably in an environment of -20 ° C to 0 ° C. The body seals are made of cold-resistant rubber, and the hydraulic system uses low-temperature hydraulic oil, which can effectively avoid component failures caused by low temperature and adapt to the low temperature environment of the cold storage.
performance differential
The low temperature environment has a great impact on the performance of ordinary electric forklifts, and the power output will fluctuate significantly. The battery life can be reduced by up to 30%, which cannot meet the long-term continuous operation requirements in the cold storage. In addition, the starting speed of ordinary forklifts is slow, and they need to be preheated at low temperatures to operate normally, which delays the operation time. Cold storage lithium-electric forklifts have more advantages in performance. Their battery management system can adjust the battery working status in real time to maintain battery activity. The battery life decay rate can be controlled within 10%, and the power output is smooth and continuous. At the same time, the cold storage lithium-electric forklift does not need to be preheated, and can be quickly started and put into operation. The hydraulic system can still maintain a smooth operation feel at low temperatures, improving the operation efficiency in the cold storage.
Maintenance differences
When an ordinary electric forklift is used alternately between a cold storage and a room temperature environment, the surface of the equipment is prone to condensation due to temperature difference. Moisture entering the circuit system may cause a short circuit, and metal parts will also accelerate corrosion. It requires frequent maintenance operations such as water removal and rust prevention, and the maintenance cost and workload are high. The cold storage lithium-electric forklift adopts a higher level of sealing design, which can effectively reduce the impact of condensation on the internal components and has a longer maintenance cycle. In terms of battery maintenance, the battery of an ordinary electric forklift needs to be regularly checked for electrolyte and charging parameters, while the battery of a cold storage lithium-electric forklift does not need cumbersome operations such as liquid replenishment. Daily maintenance only needs to clean the surface and check the connecting lines, which is easier to maintain.
Differences in cost and lifespan
From the perspective of initial procurement costs, the price of cold storage lithium forklifts is slightly higher than that of ordinary electric forklifts, but from the perspective of long-term use, the cost difference between the two will gradually reverse. Ordinary electric forklifts are used under low temperature conditions, the speed of component loss is accelerated, and the overall service life will be shortened by about 30%. Coupled with frequent maintenance costs, the long-term use cost is higher. The low temperature resistance design of cold storage lithium forklifts allows them to maintain a normal service life in a cold storage environment, with lower maintenance costs and higher overall cost performance, making them suitable for long-term operation in cold storage scenarios.
In summary, when selecting a forklift, enterprises need to consider factors such as the temperature conditions and operating requirements of the operation scene, and choose the appropriate forklift type to ensure operation efficiency and equipment stability.
