Adjust the electric forklift speed from inside the controller

Nowadays, the logistics of enterprises is becoming more and more important in the trade process. How to reduce labor costs in handling materials has become the primary issue for enterprises to consider, so electric forklifts have become the main force in material handling equipment, and the wide application of electric forklifts has replaced the The problem of manual handling reduces the cost of manual handling and also solves the difficult problem of manual handling of large materials. However, after the wide application of electric forklifts, electric lithium pallet truck manufacturers face another difficult problem to solve, that is, some users require to adjust the speed of electric forklifts.

After purchasing an electric forklift, companies that use an electric forklift may choose to let the electric forklift manufacturer adjust the speed because of the feeling of use, but this is not advisable. According to the manufacturer, the speed of each vehicle is adjusted according to national safety regulations, and the speed of the forklift will not be changed at will because of personal experience. If the company forcibly adjusts the speed and a series of safety problems occur, the manufacturer is not responsible at all. .

The speed of the semi-electric forklift is adjusted from the internal parameters of the controller, which cannot be changed externally. Therefore, adjusting the speed of the semi-electric forklift depends on the configuration of the model to see what controller. There must be professional operators or manufacturers to assist the operation to avoid unnecessary failures.

The lifting speed of the semi-electric forklift is the lifting performance requirement of the lifting system: the peak value of the lifting speed with full load is 24m/s, if the speed is greater than this range, then Indicates that a fault has occurred. If the electric pallet lift truck is too slow or the speed is too fast, the speed limiting valve installed on the base of the electric pallet lift truck cylinder can be checked. When the return spring stiffness value in the slide valve is lower than the design requirements, the slide valve and the valve hole are too tight. In this case, the spool valve will not be fully open, resulting in slow acceleration. If the throttle orifice of the spool valve is too large, the descending speed will increase. If the throttle hole is blocked by dirt, it may also cause the descending speed to be much lower than the standard value, affecting the working efficiency of the forklift. This is also not allowed, and the fault caused by the blockage needs to be eliminated immediately. If the clearance between the gantry side roller, the main roller and the gantry is too small, the lifting speed will be affected due to the increase of friction, and even the fork frame will be stuck and cannot slide down by its own weight when the load is light. The side roller shim set needs to be readjusted for greater backlash. If it is because the main roller is stuck in the channel steel of the gantry and cannot slide down, you can do several full-load lifting actions, and the fault of the semi-electric pallet truck can basically be eliminated.

There is a specialization in the technical industry. Since electric forklift manufacturers do not recommend adjusting the speed of electric forklifts at will, it is better for purchasers and users to follow the manufacturer's recommendations, and do not forcefully require adjustment of electric forklifts because of personal use. speed. In production and work, whether it is an enterprise or a manufacturer, everything must be safety-oriented. Manufacturers should also regularly check the electric forklifts they produce to ensure the safety of the electric pallet stacker they sell when they leave the factory.
