门架作为一个重要的合力叉车配件，是合力叉车取物装置的一个主要的承重结构。一般根据叉取货物起升的高度要求，合力叉车配件的门架可以做成两级或者是多级，常见的普通合力叉车多采用两级门架。那么济南合力叉车的门架应该怎么进行修理呢？

As an important part of the resultant forklift, the gantry is a main load-bearing structure of the pickup device of the resultant forklift. Generally, according to the lifting height requirements of the forked goods, the portal frame of the parts of the resultant forklift can be made into two levels or multiple levels. The common common resultant forklift mostly uses two levels of portal frame. So how should the gantry of Jinan Heli forklift be repaired?

1、修理前应进行合力叉车门架的校正，保持门架的固有直度。

1. Before repair, the gantry of the resultant forklift shall be calibrated to maintain the inherent straightness of the gantry.

2、打磨裂缝处，直露出金属光泽，然后仔细检查，确定裂纹界线，在界限延伸10mm处钻￠5-￠8mm的限止孔。

2. Grind the crack until the metal luster is exposed, and then carefully check to determine the crack boundary. Drill ￠ 5 - ￠ 8mm limit hole at the extension of 10mm.

3、在裂口处用砂轮等修磨出焊道坡口。

3. Grind the weld bead groove at the crack with grinding wheel.

4、进行填焊时，用直流反极性电弧焊。电弧应尽可能短，焊条直径为4mm，电流约为210-240a。焊接时焊条应倾向运动方向20°-30°。填焊工作自钻透孔开始直裂纹另一端，并在反面也进行焊补，焊缝高度应不超过基体平面1-2mm。焊接时环境温度应在0℃以上。

4. DC reverse polarity arc welding shall be used for filling welding. The arc should be as short as possible, the electrode diameter is 4mm, and the current is about 210-240a. During welding, the electrode shall incline to the movement direction of 20 ° - 30 °. The filling and welding work starts from drilling through the hole to the other end of the crack, and the welding repair is also carried out on the reverse side. The weld height should not exceed 1-2mm of the base plane. The ambient temperature during welding shall be above 0 ℃.

此外合力叉车搬运不仅能减少劳动力，而且还能提高搬运效率，也在更大程度上降低货物在搬运中的破损。当然在合力叉车中合力叉车配件对合力叉车来说是十分重要的。要重视合力叉车的几个重要的配件，做好对合力叉车的保养工作不能忽视合力叉车在底盘上、变速箱上的配件。这样你的合力叉车才能够高能效率、高能效果地工作，降低使用成本，减少维修次数。

In addition, the combined force forklift can not only reduce the labor force, but also improve the handling efficiency, and also reduce the damage of goods in the handling to a greater extent. Of course, in Heli Forklift, Heli Forklift accessories are very important for Heli Forklift. We should pay attention to several important parts of Heli Forklift, and do a good job in the maintenance of Heli Forklift. We cannot ignore the parts of Heli Forklift on the chassis and gearbox. In this way, your resultant forklift can work with high energy efficiency and efficiency, reduce the use cost and reduce the number of maintenance.
