What is the relationship between the size of the screening bucket? The general opinion of excavator grab customers in China is that the bigger the bucket, the better. The bigger the car, the more efficient it is. This is clearly a wrong view. Another argument is that the stronger the bucket, the better, so the bucket is dressed in heavy "armor". Such an approach is also obviously unreasonable. Then if it is not reinforced at all, it will not get high use economy.
The reinforcement of the excavator grab should pay attention to two things: one is effective, and the other is firm. If you protect the bucket in all directions, as shown in the figure below, it will inevitably increase the weight of the bucket per bucket you dig. A heavier bucket will not only increase the fuel consumption of the machine, but also have a considerable impact on the life of the machine. This little bit of loss cannot be ignored.
Caterpillar once did a study that showed that for every 0.5 tons of excavator grapple weight, the cycle time increased by 10% and the annual gross profit decreased by 15%. Therefore, it is necessary to weld in the parts that need to be strengthened. And not finishing welding. The second is that the welding must be firm, if you have stiffeners sticking everywhere on the bucket, suddenly one day the weld cracks, and the small iron falls into your crusher. Then the losses may be large.
