An excavator is a construction equipment commonly used for earthwork. The micro excavator is smaller than a mini excavator and is suitable for working in tight spaces. The China mini excavator sales people will be looking at the below types when it comes to sales.
Mini Excavators:
A mini excavator generally refers to a machine weighing less than 5 tons. It is also known as a compact excavator or a small excavator. To enable flexible and cost-effective handling of smaller projects, many manufacturers have developed excavators that are considerably lighter than full-sized excavators. The crawler type can move on its own, while the backhoe type requires operation by an experienced person. Some have a 360-degree rotation.
Midi Excavators:
These excavators are defined as weighing between 5 to 10 tons. The way they look and perform is similar to mini excavators. But their speed and working capacity are more than the mini ones. In some situations, the midi can be more suitable because they can have a more powerful engine and a longer reach.
Compact Track Excavators:
Compact track excavators are crawler-type mini excavators, also known as rubber tracks. Similar to a mini excavator, the compact track excavators are controlled by an operator with the aid of joysticks to dig, move and load materials with precision. However, they are designed to be operated in rough terrain. They have a tracked undercarriage that provides excellent stability and traction on uneven or muddy ground. If work needs to be done in a location that has hills and uneven terrain, these excavators will be the right choice.
ZTS Excavators:
Zero tail swing (ZTS) mini excavators are defined as excavator machines whose tails don’t swing outside the width of the machine. In simpler terms, the excavator's upper house, which contains the cab and counterweight, does not extend beyond its lower tracked undercarriage. They work well in confined spaces and when there is limited maneuvering space and have a counterweight that moves within its footprint.
Wheeled Excavators:
These excavators have wheels instead of tracks. This provides them with the needed speed for long-distance travel and high mobility. These excavators have an arm and bucket attachment for scooping material. In some cases, they can have a clamshell bucket for digging and loading or a thumb attachment to grasp larger objects.
Operating weight:
Operating weights for mini excavators usually range from 1 ton to 6 tons. Higher operating weight confers greater digging capacity, stability, and overall strength. Smaller excavators are more suited to confined spaces and light tasks. Conversely, larger models are ideal for substantial construction projects or infrastructure development.
Engine Power:
The engine power—and, by extension, the horsepower—of a mini excavator will dictate its digging strength and the operation of auxiliary attachments. Generally, mini excavators have between 15 and 50 horsepower. Smaller excavators work well with shallow digging and basic earthmoving functions. Larger horsepower mini excavators are necessary for heavier tasks, like trenching and demolition.
Bucket capacity:
Bucket capacities of mini excavators fluctuate according to the size and model of the excavator. They usually run between 0.02 and 0.1 cubic meters. A smaller bucket capacity will suffice for routine excavation, loading, and backfilling tasks. Projects requiring higher capacity and efficiency will require an excavator with a larger bucket capacity.
Digging Depth:
Mini excavator digging depth varies according to type and model, ranging approximately between 1.5 to 4.5 meters (5 to 15 feet). Depth is an important aspect of the excavator's ability, as it defines the depth of trenches and holes the excavator can reach, especially in relation to foundation digging and utility clearance.
Reach:
The reach of a mini excavator corresponds to how far horizontally the excavator can extend its arm. Mini excavator reach varies according to type and model, ranging approximately between 3 to 5 meters (10 to 16 feet). Weight distribution, digging and heavy work efficiency, and maneuverability in confined spaces largely depend on the reach of a mini excavator.
Frequent maintenance checks and services for the excavator are required to keep it in peak operating condition and prevent breakdowns and failures during critical project phases. Users of the mini excavator should follow the maintenance schedule recommended by the manufacturer and perform the procedures outlined carefully to ensure safety and prolong the machine's life.
Daily Checks:
These are routine inspections that should be carried out before or after any use of the excavator. The user should conduct a thorough visual inspection of the entire machine and note any leaks, loose parts, damaged components, etc. All fluid levels—engine oil, hydraulic fluid, coolant, and fuel—should be carefully checked and topped up where necessary. The condition of tracks, tires, and buckets should also be inspected and any abnormalities addressed immediately.
Weekly Maintenance:
More in-depth inspection and maintenance should be done weekly or after every 40 hours of operation. Clean the air filter to ensure engine performance and remove any debris buildup in the hydraulic coolers and radiators. Inspect all belts and hoses—checking for wear, cracks, or leaks—and lubricate all pivot points and grease fittings to reduce friction and wear. Finally, the user should also check the tightness of bolts and screws and confirm the attachment's connections to ensure operational safety.
Monthly Maintenance:
Users should replace the engine oil and oil filter after every 200 hours of operation or at least once a month. The hydraulic system's hoses, belts, and components should be inspected thoroughly for wear or leaks. Operation hour meter readings should be noted so that scheduled servicing and replacement of key components can happen on time. The tracks and undercarriage components should be inspected and cleaned to remove any stuck dirt or debris to improve stability and traction.
The construction industry makes up the largest application for mini excavator sales as a construction machinery product. Since China is one of the largest construction countries, the sales volume remains high. In recent years, with the gradual development of smaller housing projects and steady infrastructure investment, the mini excavator has become an essential tool in the industry. Specifically, in rural construction, municipal construction, and circuit network engineering.
In the agricultural sector, mini excavators are used for tasks such as land preparation, dredging of irrigation canals, construction of drainage systems, and greenhouse construction, among others. Their versatility and efficiency contribute to improving agricultural productivity.
The road maintenance sector also benefits from the use of mini excavators. They are employed in task such as pothole repair, road surface reconstruction, drainage system maintenance, and landscaping operations. Mini excavators enable efficient and precise mini-excavation and repair work, ensuring the quality and safety of road maintenance.
Mini excavators find applications not only in construction but also in municipal administration. They are used for tasks such as urban garbage disposal, public facility maintenance, green belt landscaping, and winter snow clearance. Mini excavators enhance work efficiency and quality, contributing to the orderly operation and management of urban municipalities.
Additionally, mini excavators play a valuable role in disaster relief and rescue efforts. They are used in tasks such as removing disaster debris, restoring damaged infrastructure, and conducting search and rescue operations. Their agility and efficiency facilitate timely and effective rescue operations.
In newly emerged industries, such as the shale gas industry, mini excavators are playing a significant role. They are used for tasks such as well site construction, pipeline excavation, and equipment installation. Their flexibility and efficiency meet the demand for mini excavation and construction in the shale gas sector.
Furthermore, the rental market for mini excavators is booming. Many construction companies and individual workers choose to rent excavators instead of purchasing them due to cost considerations and project uncertainty. Mini excavator rental not only meets market demand but also spurs mini excavator sales.
When buying a mini excavator, there are a few things that buyers should consider. These factors are related to their construction needs and business model.
Identifying business needs:
The first step in buying a mini excavator is to identify the business's needs. Ask questions about the excavator's tasks. What types of excavating tasks will the excavator execute? What size of the excavator is needed? What are the specific features and attachments required?
Assessing project requirements:
Step two involves assessing project requirements and conditions. This includes checking the excavating depth and soil condition, as well as the dimensions and access of the project site. When these parameters are established, buyers can now look for excavators with the right digging depth and ground clearance. They should also choose models with suitable power ratings.
Considering machine versatility:
Buyers should consider the excavator's versatility. This can help buyers purchase excavators with excavating and other useful capabilities. Excavators that support several attachments cut costs and improve efficiency.
Comparing new and used excavators:
