How to judge whether the gantry performance of electric stacker truck is good?

Whether it is a new electric stacker truck just purchased or an old electric stacker truck just maintained or repaired, we should check whether its devices and parts can work properly. No matter what the forklift price is, the working device is an important part of the electric stacker truck, and it should be checked frequently to see whether its performance is good. Among them, the gantry is the main component of the working device. How can we judge whether the gantry performance of the electric stacker truck is good? Next, the electric forklift manufacturer will tell you about its judgment method.

The gantry is the main load-bearing structure of the electric stacker truck pickup device, and the overlapping structure is generally adopted. According to the requirements of cargo lifting height, it can be divided into two-stage gantry and multi-stage gantry. Generally, the electric stacker truck will use two-stage gantry. The two-stage gantry can also be divided into three sections of fully free gantry, two sections of fully free gantry, two sections of standard gantry, etc. The gantry with good performance has the following standards: the internal and external gantry can be well matched, slide flexibly, and there is no problem of jamming. The portal frame shall be free of cracks, defects affecting the strength and rigidity, and the deformation shall not exceed the design allowable value. No matter what the forklift price is, the portal frame shall not have deformation and weld seam desoldering.

The relative lifting of the inner and outer gantries of the electric stacker truck, the accessory frame and the inner gantry should be smooth, the fit clearance between the gantry and the roller should not be greater than 1.5mm, and the sliding should be good without jamming. The roller shall rotate flexibly. The roller and shaft shall be free from cracks and damages. The wear of the groove shall not be greater than 10% of the original size. The tightness of the two lifting chains shall be uniform without distortion and deformation, and the ends shall be firmly connected. The fit clearance between the chain link pin shaft and the bearing hole shall not be too large, the sprocket shall rotate flexibly, and the groove depth shall not exceed 0.05mm of the original size. No matter what the forklift price is, the accessory frame should not have serious deformation or weld seam cracking.

The above is the method to judge whether the gantry of the electric stacker truck has good performance. The electric forklift manufacturer reminds that after purchasing a new forklift or maintaining a forklift, systematic inspection should be carried out according to this standard. We all know the importance of the gantry. No matter what the forklift price is, the gantry is a very important part of the electric stacker truck. Therefore, it is very important to have a portal with good performance.
