What to do if the gantry of the electric forklift has problems?

Electric forklift is now widely used for cargo handling, lifting and stacking. As we all know, the lifting of the electric forklift mainly depends on the gantry. If the gantry has problems, it will bring a lot of inconvenience to the work of the electric forklift and affect the work efficiency. So, what are the common problems of the gantry? How should drivers deal with these problems? No matter what the forklift price is, the problem can be solved by checking and repairing according to the instructions of the electric forklift manufacturer.

First of all, if the portal frame or fork frame of the fully electric forklift is stuck, the lifting speed becomes significantly slower, and even when it descends with no load, it cannot slide down by its own weight. The main reason may be that the clearance between the main roller, side roller and the portal frame is too small, or the inner and outer portal frames are deformed. In this case, it is necessary to remove the mast and check the fit clearance between the roller and the mast. If the clearance is too large or too small, it can be adjusted by adding or removing shims. Then check the deformation of the inner and outer gantries and correct them in time. If the plane of the fork inclines to the side of the forklift when the mast is lifted and lowered, it may be because the side roller clearance is too large, the tension of the two chains is too uneven, and the driving tire pressure is not equal. What the driver should do is to check the pressure of the driving tire first, and replenish the air in time if necessary. Then check whether the tension of the two chains is consistent, and timely adjust if not. Finally, check the side rollers and the mast. The electric forklift manufacturer reminded that no matter what the forklift price is, it should be checked in this order.

If the portal frame and fork frame of an electric forklift vibrate violently and generate noise during operation, it may be caused by excessive fitting clearance between the rollers and the portal frame or loosening of fasteners. At this time, it is necessary to remove the portal frame and fork frame, check the fit clearance between the portal frame, fork frame roller and the portal frame, adjust them in time, and then check the fasteners. If the gantry jumps during lifting, there are several reasons as follows: first, there is air in the lifting cylinder; Second, the gear pump has poor performance; Third, the reversing valve is not flexible; Fourth, the oil is not clean. In case of such a problem, you can first loosen the vent plug on the lifting cylinder, discharge the air in the lifting cylinder, and then check whether the oil is clean. Next, no matter what the forklift price is, if the problem of the electric forklift has not been solved, it is necessary to check the operation of the reversing valve and the gear pump, and repair or replace the problem in time.

The above are the problems that may occur to the mast of an electric forklift. The electric forklift manufacturer told everyone not to panic when encountering problems. No matter what the forklift price is, you can do as we say. If you have other questions, you can consult the electric forklift manufacturer.
