The application of excavators is becoming more and more extensive, and many entrepreneurs want to enter this industry. It is very important to choose a suitable excavator. There are many types of excavators on the market. Faced with many brands, prices and models are also very different. How should we make a choice? You can consider the following aspects.
1. Excavator parameters and configuration
The operating weight of the excavator determines the upper limit of the excavator’s digging force. If the digging power exceeds this limit, in the case of a backhoe, the excavator will slip and be pulled forward, which is very dangerous. In the case of a front excavation, digging The excavator will skid backward. The selection of the excavator should be based on the actual needs, the construction environment, and the supporting vehicles on the construction site. The model of the excavator is closely related to the weight. To maximize their interests, some manufacturers will use the 10% legal weight floating ratio to cut corners in the production process of the excavator, thereby indirectly reducing the cost performance of the excavator. Therefore, when choosing an excavator, we should look at the excavator’s brand and model and pay attention to their actual weight.
Total excavator power refers to the output power measured at the engine flywheel without power-consuming accessories such as mufflers, fans, alternators, and air filters. Excavators of different tonnages correspond to different engine powers and can be reasonably selected according to their construction environment.
Bucket capacity refers to the volume of material that the bucket can hold. An excavator can be equipped with buckets of different sizes according to different material densities. Good selection of bucket capacity is one of the important means to improve work efficiency and reduce energy consumption. When purchasing an excavator, carefully check whether the bucket body is worn and cracked and whether the bucket teeth are stable and loose. There are various types and uses of excavator buckets. You should select the bucket suitable for the project according to the project. The following buckets are introduced:
Earthmoving buckets are the most common, and earthmoving buckets are generally equipped with backhoe excavators. It is suitable for the excavation of general clay and loading sand, soil, gravel, and other lightwork occasions. The reinforced earth moving bucket can excavate hard soil mixed with soft ground, soft stone, crushed stone, gravel loading, and other heavy-duty operations.
For the rock bucket, the high-stress part is specially strengthened, the material of the wear-resistant part is thicker, and there are reinforcing ribs at the bottom. There are reinforcements on the bucket teeth, bucket fins, both sides of the bucket teeth, and the bottom of the bucket. In addition, the rock bucket adds side guards and installs guards. It is suitable for the excavation of hard stones, sub-hard stones, and weathered stones mixed in the soil; heavy-duty operations such as loading hard rocks and blasted ore.
The ripper bucket is mainly used for crushing, excavating, and hard loading soil, sub-hard stone, weathered stone, or construction of frozen soil. The bucket is equipped with high-strength loosening teeth, which has a large digging strength; the loosening excavation is completed at one time, and the operation efficiency is high.
The thumb bucket is equipped with a baffle plate in front of the bucket, reducing the possibility of the material falling or directly grabbing the material. It is suitable for materials that are easy to fall over when excavating and loading, especially for sites with high loading and lifting.
2. Brand and sales
Stable sales are the basic premise to measure the reliability of a brand product, and they can also reflect the market’s recognition of the brand. As construction machinery, excavators are d to create economic benefits. If there are many loopholes due to quality problems, such a brand will not be recognized by the market, and sales will decline sharply over time, so the brand can be a quality guarantee for buyers. Although some brands will win a temporary sales surge with brief promotion strategies or new models, brands with stable sales are more suitable choices in the long run.
3. Fuel consumption
When buying an excavator, we also need to consider fuel consumption. Due to the different types and working intensity of excavators and the other gears when the excavator is operating, fuel consumption deviates, so fuel consumption is uncertain. At this time, while referring to the parameters of the excavator, you can also consult the actual operating experience of other excavators in the same industry, and then compare the fuel consumption of excavators of the same type and different brands, and choose the excavator that best suits your work needs.
4. Second-hand hedging rate
If the excavator is used for a long time, it will be worn or damaged. If you want to sell it at that time, you must consider the value preservation rate of the excavator. Therefore, you should consider the excavator’s brand, reputation, quality, and other aspects when purchasing—a cost-effective product.
5. Operating comfort
The comfort of excavator operation will affect work efficiency. When purchasing excavators, comfort is also an important aspect that we need to consider. Carefully consider whether the cab, seat, operating handle, heating and cooling system, noise, vision, etc., are complete to reduce operator fatigue and increase comfort.
When purchasing excavation, the first thing to consider is the economic benefits. Therefore, it is necessary to comprehensively consider the project scale, project supporting conditions, and existing capital status and make selections within the budget range combined with the return on investment.
7. Spare Parts Inventory
If the excavator body parts are damaged during the construction process, the manufacturer needs to provide excavator parts in time. Therefore, before buying an excavator, we must know whether this manufacturer’s spare parts storage capacity can meet the needs of all buyers. If the excavator cannot work for a long time due to the manufacturer’s spare parts, the economic loss caused is undoubtedly huge.
8. After-sales service
The long-term construction of the excavator, coupled with the working environment of wind and sun, severe cold and heat, and explosive soil and dust, will inevitably lead to some failures during the construction process. Therefore, when we buy excavators, we must consider the after-sales support capabilities of excavator manufacturers in advance to deal with faults in time and recover economic losses. Find out when and how after-sales personnel can provide maintenance services for excavators, whether they can help maintain equipment, whether local maintenance is convenient, whether the source of accessories is shared, whether the price is reasonable, and if the excavator fails, whether the service personnel can come to the door in time to troubleshoot, etc. Therefore, whether the after-sales service of excavator manufacturers can be in place is also an essential factor in buying excavators.
Finally, you must choose a regular excavator manufacturer with quality assurance services. You cannot blindly pursue low prices but ignore product quality. You should fully consider the cost of the manufacturer’s technology, environment, equipment, and personnel, and You should select products with appropriate fees and rates. During the warranty period, if any part of the excavator is defective in design or manufacture, the manufacturer is obliged to repair or replace the wrong part free of charge.
