In a low-temperature environment, the operating state of a lithium-ion forklift truck can be affected by a variety of factors, and there are many limitations to its use. Understanding these limitations can help to operate more safely and efficiently.
Limited performance of battery performance
The low temperature environment will inhibit the chemical reaction activity inside the battery, resulting in a decrease in the discharge capacity of the battery and a reduction in the range to varying degrees. At the same time, the charging efficiency will also be significantly reduced. In some cases, the battery even needs to be preheated before it can be charged normally. If it is directly charged at low temperature, it may cause damage to the internal structure of the battery and shorten the overall service life of the battery. In addition, the low temperature environment may also cause the output voltage of the battery to be unstable, affecting the power output continuity of the forklift.
Risk of operational performance degradation
The hydraulic system is slow to respond
The viscosity of hydraulic oil at low temperatures will increase significantly, which will reduce the power transmission efficiency of the hydraulic system, and slow down the response speed of operations such as fork lifting and steering. This will not only reduce the operation efficiency, but also may cause errors in scenarios that require precise operation, increasing safety hazards such as collisions and cargo drops.
Braking and steering stability are affected
In low-temperature environments, the components of the braking system may experience performance fluctuations due to temperature reduction, and the braking distance may be extended; at the same time, the resistance of the steering system increases, and the operator needs to apply more force to complete the steering operation. In slippery or icy workplaces, the risk of this stability decline will be further increased.
Acceleration of component losses
Low temperature will make the rubber seals, plastic parts and other materials of the forklift hard and brittle, the sealing performance will decline, and it is prone to problems such as hydraulic oil leakage and reduced electrical circuit insulation. In addition, the elasticity of the tire is weakened in the low temperature environment, and the change of friction with the ground will not only accelerate the tire wear, but also may affect the driving stability. Operating in a low temperature environment for a long time will significantly accelerate the aging rate of each component of the forklift, requiring more frequent inspection and maintenance.
Additional restrictions on job scenarios
In an extremely low temperature environment, the forklift may have difficulty starting, and the whole machine needs to be preheated in advance to start normally. At the same time, low temperature will affect the operator's limb flexibility and indirectly reduce the operation efficiency. Therefore, it is necessary to arrange the operation time reasonably, avoid long-term continuous operation, and equip the operator with appropriate cold protection equipment to ensure the safety of the operation.
Overall, the use of lithium-ion forklifts in low-temperature environments is limited in many ways. Before operation, it is necessary to fully understand these influencing factors, prepare for preheating and maintenance, and plan the operation process rationally in order to ensure the stable operation of forklifts in low-temperature scenarios and prolong the service life of equipment.
