The rental of long arm excavators is needed in many engineering construction. I'd like to introduce the points that need to be paid attention to in the reinforcement of the bucket of long arm excavators.

1.齿根处的加强保护

1. Strengthen the protection at the tooth root

长臂挖掘机齿根安装板的加强非常有必要，如果在此处的加强不好，会导致磨损将剧烈，牙齿怎么也装不上去了。对于此处的加固可以采取两种方案，一种是贴加强筋，一种是包耐磨块。需要注意的是，贴加强筋的做法简便，经济，但是焊接时要注意不能与齿根的焊缝产生叠焊，这样会影响齿根焊接强度。

It is very necessary to strengthen the tooth root mounting plate of long arm excavator. If the reinforcement here is not good, it will cause severe wear and tear, and the teeth can't be installed. For the reinforcement here, two schemes can be adopted, one is to stick stiffeners and the other is to wrap wear-resistant blocks. It should be noted that the method of attaching stiffeners is simple and economical, but during welding, it should be noted that overlapping welding with the weld of the tooth root will not occur, which will affect the welding strength of the tooth root.

2.边板及侧边加强

2. Side plate and side reinforcement

边板的剧烈磨损会使挖斗的斗容减小，影响生产力。同时，边刀也起到利于切入物料，保护边板的效果，所以挖斗需安装边刀。长臂挖掘机由于侧边并不是高磨损区，故侧边的加强不用太坚固，以免影响挖斗的整体重量。

The severe wear of the side plate will reduce the bucket capacity of the bucket and affect the productivity. At the same time, the edge knife also has the effect of cutting in materials and protecting the edge plate, so the edge knife needs to be installed in the bucket. Since the side of the long arm excavator is not a high wear area, the reinforcement of the side need not be too strong to avoid affecting the overall weight of the bucket.

3.底板加强

3. Base plate reinforcement

底板加强是非常有必要的。底板的加强筋要选择坚硬、耐磨的长型板材做原料，要保护挖斗的整体形状，以免影响切入角度，影响产能。加强筋的焊接要顺着原机筋板焊接的方向，在两块板上叠焊。

It is very necessary to strengthen the bottom plate. The stiffener of the bottom plate shall be hard and wear-resistant long plate as raw material, and the overall shape of the bucket shall be protected to avoid affecting the cutting angle and production capacity. The welding of stiffeners shall be overlapped on the two plates along the welding direction of the original stiffener plate.

4.挖斗内面的加强

4. Strengthening of inner surface of bucket

长臂挖掘机厂家的小编建议内面加强使用硬面堆焊，虽然价钱高，耗时长。但是它的耐磨性跟实效性是非常强的，或者也可以选择贴部分加强筋，不宜过多。

The small editor of the long arm excavator manufacturer suggests to strengthen the use of hard surfacing on the inner surface, although the price is high and time-consuming. However, its wear resistance and effectiveness are very strong, or you can choose to stick some stiffeners, which should not be too much.
