How to Choose the Right Excavator Tonnage Based on Your Working Scenario?

The tonnage of an excavator must be strongly matched to the working scenario, with core references to operation intensity, site constraints, and supporting equipment. Specific classifications for reference are as follows:

Mini (1-6 tons): Suitable for operations in narrow spaces, such as indoor renovation demolition, small courtyard renovation, and municipal pipe network excavation (pipe diameter ≤ 600mm). Its advantage lies in high flexibility, being able to pass through narrow passages (width ≤ 1.8 meters).

Small (6-15 tons): Mainstream models for municipal and agricultural use, applied in rural road construction, farmland water conservancy excavation, and foundation construction of small and medium-sized houses. They can work in coordination with 40-60 type loaders, balancing efficiency and flexibility.

Medium (15-25 tons): Core models for engineering construction, suitable for foundation excavation of commercial housing, subgrade construction of expressways, and stripping operations in medium-sized mines. They can be matched with 15-20 ton dump trucks, with a single bucket capacity of 0.8-1.2 cubic meters, achieving the best balance between operational efficiency and economy.

Large (over 25 tons): Used in heavy-duty scenarios such as large mines, water conservancy hubs (e.g., reservoirs, hydropower stations), and port terminals. The bucket capacity is ≥ 1.5 cubic meters, and they need to be matched with heavy dump trucks of over 25 tons. The core requirement is "high-intensity continuous operation", so special attention should be paid to engine durability and the load-bearing capacity of the hydraulic system

What Types of Excavator Buckets Are There? Can They Be Customized?

Conventional excavator buckets are divided into 3 types by function, and customized requirements are also supported:

Standard Earth-Moving Bucket: A universal type with a bucket capacity matching the excavator's tonnage and moderate bucket tooth spacing. It is suitable for excavating loose materials such as soil and gravel, accounting for more than 80% of the market sales.

Rock Bucket: It features a reinforced design, with the bucket body made of 16-20mm wear-resistant steel plates and bucket teeth in a combination of pointed teeth and wide teeth. It is suitable for excavating weathered rocks and gravel layers, which can reduce bucket body deformation and tooth seat wear.

Crushing Bucket (Screening Bucket): A special-function bucket with built-in crushing teeth or screening grids. It can directly crush/screen construction waste and ore on-site, avoiding secondary transportation of materials, and is suitable for environmental protection and recycling projects.

Customization Instructions: Customization is supported according to special operation needs (such as extra-long bucket arms, narrow bucket bodies, anti-corrosion coatings, etc.). The customization cycle is generally 15-30 days, and an additional 10%-30% customization fee is required. The feasibility of the customization plan needs to be confirmed with the technical team in advance.

Excavator Warranty Period and Coverage

Regular Warranty Policy

Whole Machine Warranty: 1 year or 2000 operating hours (whichever comes first), covering component damage caused by non-human faults.

Extended Warranty for Core Components: For core components such as the engine, hydraulic pump, and swing motor, an extended warranty can be purchased to extend the coverage to 2 years or 4000 operating hours (the extended warranty cost is approximately 2%-3% of the total equipment price).

Warranty Coverage Description：Covered Components， Engine， Hydraulic system (main pump, main valve, oil cylinder)， Transmission system (travel motor, swing mechanism)， Main cab structure， Uncovered Components (Wear Parts / Human-Induced Loss)， Bucket teeth， Filters， Tires / track shoes (normal wear and tear)， Glass (accidental breakage)， Component damage caused by improper operation (e.g., overloaded operation, failure to perform maintenance on schedule)
