What is the bottom plate of the excavator?
In the field of construction machinery, the bottom plate of the excavator is a key component, which directly affects the stability and work efficiency of the equipment. This article will provide you with a comprehensive analysis of the relevant knowledge of the excavator floor from the perspectives of definition, function, material, frequently asked questions and market data, and also attaches relevant analysis of hot topics in the past 10 days.
1. Definition and function of excavator bottom plate
The excavator base plate (also called track shoe) is the core component of the excavator track system. It is located at the bottom of the track link and directly contacts the ground. Its main functions include:
1. Disperse mechanical weight and reduce ground pressure
2. Provide grip and prevent slipping
3. Protect the internal structure of the track from wear
2. Material and type of excavator bottom plate
| type | Material | Applicable scenarios | Lifespan (hours) |
|---|---|---|---|
| Standard type | Mn13 high manganese steel | Ordinary earthwork work | 2000-3000 |
| Enhanced | Alloy steel + rubber pad | Mine crushing operations | 1500-2000 |
| Wetland type | Wide steel plate | swamps, muddy areas | 1800-2500 |
| Rubber type | Steel core + rubber wrapping | urban road construction | 1000-1500 |
3. Hot topics in the construction machinery industry in the past 10 days
| Hot search keywords | heat index | Related events |
|---|---|---|
| Excavator maintenance | 85,000 | Demand for equipment maintenance surges during rainy season |
| New energy excavator | 123,000 | Sany releases new electric excavator products |
| Infrastructure investment | 156,000 | The Ministry of Finance increases the quota of special bonds |
| second hand excavator | 68,000 | Second-hand machinery trading platform financing |
4. Analysis of common problems with excavator bottom plates
1.Abnormal wear and tear:This is usually caused by sharp objects on the working floor or substandard floor material. The thickness of the floor needs to be checked regularly (it is recommended not to be less than 60% of the original thickness).
2.Loose connections:Insufficient pre-tightening force of bolts may cause the base plate to fall off. They should be tightened regularly according to the manufacturer's standard torque.
3.Rubber pad aging:Ultraviolet radiation and oil pollution will accelerate the aging of rubber. It is recommended that urban work equipment be inspected every 500 hours.
5. Excavator base plate market data in 2023
| parameter | Domestic market size | annual growth rate | Main brands |
|---|---|---|---|
| original parts | 1.8 billion yuan | 5.2% | Komatsu, Caterpillar |
| Sub-factory parts | 2.7 billion yuan | 12.7% | XCMG, Lingong |
| remanufactured parts | 900 million yuan | 23.5% | Regional repair shops |
6. Purchase suggestions
1. Choose the appropriate type according to the working conditions. Reinforced bottom plates are recommended for mining operations.
2. Check whether there are quality certification marks such as ISO9001
3. Compare the cost performance of original parts and auxiliary parts. Generally, the price of auxiliary parts is 30-50% lower.
4. Pay attention to recent industry exhibition information (such as the Shanghai Construction Machinery Exhibition in September) to obtain the latest product trends
7. Technology development trends
1.Composite material applications:Carbon fiber + metal hybrid blade can reduce weight by more than 20%
2.Intelligent monitoring:Some high-end models are equipped with base plate wear sensors
3.Environmental requirements:The EU will implement new heavy metal content standards in 2024
From the above analysis, it can be seen that although the excavator bottom plate is a small part, it is of great importance. It is recommended that users combine recent industry hot spots and their own needs to formulate scientific purchasing and maintenance strategies.
