How to choose the right bucket assembly
Youdaoplaceholder0 I. Analysis of Core Selection Elements
Youdaoplaceholder0 1. Working condition type and material characteristics
Youdaoplaceholder0 Hard rock/blasting ore : Rock bucket is selected as an option. The bucket wall thickness should be ≥25mm and the bucket teeth should be made of 45MnB alloy steel. The impact resistance of each tooth should be ≥150kJ.
Youdaoplaceholder0 clay/sludge : The dredging hopper is preferred. The inner wall should be sprayed with a high-molecular anti-sticking coating (thickness ≥0.8mm), and the hopper capacity should be expanded to 1.2m³ to reduce adhesion.
Youdaoplaceholder0 Loose soil : Compatible with enlarged earthwork buckets, the arc-shaped bucket wall design can reduce excavation resistance by 12%, and the bucket capacity can be expanded to 1.05m³ to increase the single loading capacity.
Youdaoplaceholder0 2. Balance between efficiency and durability
Youdaoplaceholder0 Working intensity : For high-impact conditions, reinforced pin shaft assemblies (such as models 148-3307 and 254-3052) are required to extend service life.
Youdaoplaceholder0 Time requirement : When frequently switching attachments, the hydraulic quick-change device (ISO 13031 certified) can compress the switching time to within 30 seconds.
Youdaoplaceholder0 3. Compatibility of the entire machine
Youdaoplaceholder0 Weight limit : The overall working weight of the CAT320 GX is 19.8 tons, and the bucket assembly must meet a reasonable counterweight range of ≤1.8 tons.
Youdaoplaceholder0 Hydraulic matching : The main pump pressure is 34.5MPa. It is necessary to ensure that the bucket hydraulic circuit is compatible with the system with a flow regulation accuracy of ±2%.
Youdaoplaceholder0 II. Suggestions for optimizing the bucket structure
Youdaoplaceholder0 1. Wear-resistant design
The bottom plate and the tooth seat plate are made of Swedish HARDOX500 wear-resistant steel plate (hardness HB500), and their service life is 40% longer than that of the standard bucket.
X-shaped reinforcing ribs have been added inside the bucket body, increasing its resistance to eccentric loads by 30%.
2. Unloading efficiency
The asymmetric bucket tooth layout and the design of sparse and dense holes result in a residue rate of less than 3%, reducing the frequency of slag cleaning compared to traditional buckets.
Note: The actual selection should be comprehensively verified by combining the test data of the bucket lifting force (it is recommended to be ≥136kN) and the load curve of the hydraulic system
