I. What is the Core Parameter of a Loader? How to Choose One When Purchasing?

The core performance parameter of a loader is its rated load capacity.

Rated load capacity refers to the maximum mass of materials that a loader bucket can carry under safe operating conditions (unit: t). It directly determines the equipment's operating efficiency, applicable scenarios, and overall operational costs.

This parameter must match the density of the materials being handled (e.g., sand and gravel have a density of approximately 1.6 t/m³, while coal has a density of around 0.8 t/m³) as well as the bucket volume. For example: "The SINOMACH 955T Loader has a rated load capacity of 5 t and comes standard with a 3 m³ bucket. It is suitable for high-density materials such as sand, gravel, and ore, enabling efficient one-time transfer of approximately 3 m³ of sand and gravel."

Rated load capacity is jointly determined by the loader's structural strength, hydraulic system performance, and overall stability, making it the primary basis for customer selection.

A higher rated load capacity requires the loader to be equipped with a more powerful engine and a more robust chassis to ensure driving and lifting stability under heavy-load conditions. For instance, the SINOMACH 955T model has a rated load capacity of 5,000 kg, is equipped with a 162 kW turbocharged engine, features a hydraulic system pressure of 19 MPa, and uses a self-manufactured heavy-duty frame, which can meet the requirements of heavy-load operations. It is suitable for scenarios such as loading and unloading in sand and gravel yards, aggregate transfer at concrete mixing plants, rural infrastructure construction, and earthwork projects at small and medium-sized construction sites.

II. How to Select a Loader with Appropriate Rated Load Capacity?

To select a loader that not only meets operational requirements but also reduces costs, consideration should be given to operating scenarios, material characteristics, supporting equipment, and operational costs.

1.Clarify the Operating Scenario•Small-scale sites (e.g., orchards, small-scale breeding farms, municipal landscaping): Prioritize small-rated load capacity models ranging from 0.8–2 t, which offer flexible steering and adaptability to narrow spaces.•Medium-scale sites (e.g., sand and gravel yards, mixing plants, small and medium-sized infrastructure construction sites): Choose models with a rated load capacity of 3–5 t, which balance efficiency and flexibility to meet the needs of regular material loading, unloading, and transfer.•Large-scale sites (e.g., mines, large ports, open-pit coal mines): Opt for heavy-duty models with a rated load capacity of 6–12 t or above, suitable for large-tonnage material transfer and compatible with the loading requirements of large trucks.

2.Match Material Characteristics•Lightweight and loose materials (e.g., coal, straw, wood chips): Due to their low density, a combination of moderate rated load capacity and a large-volume bucket is recommended to increase one-time loading capacity.•High-density materials (e.g., ore, iron ore, granite aggregates): It is essential to select models with higher rated load capacity to avoid equipment malfunctions caused by overloading.

3.Coordinate with Supporting EquipmentThe rated load capacity of the loader must match the load capacity of the transport truck. As a general principle, rated load capacity of loader × number of loading cycles ≈ rated load capacity of truck. For example, a 15 t load truck is optimally paired with a 5 t loader, allowing the truck to be fully loaded in 3 cycles for maximum efficiency.

4.Calculate Operational CostsModels with higher rated load capacity incur higher procurement costs, fuel consumption, and maintenance expenses, while small-rated load capacity models have lower costs but limited efficiency. The selection should be based on daily operation volume: prioritize large-tonnage models if the daily operation volume exceeds 1,000 t; otherwise, choose small or medium-tonnage models.

III. How Should Different Customer Groups Consider Loader Selection?

1.Individual farmers, municipal sanitation departments, small-scale warehousing enterprises, and property parks can choose small loaders with a rated load capacity of 0.8–3 t, such as the 937H model, which are flexible, lightweight, easy to operate, and fuel-efficient. These loaders are ideal for applications including fertilizing and handling in small farms and orchards, municipal sanitation snow removal, and loading/unloading operations in small warehouses.

2.Sand and gravel yard owners, mixing plant operators, small and medium-sized construction companies, and leasing companies may opt for medium loaders with a rated load capacity of 3–5 t, such as the 955T model, which offer high cost-effectiveness, a balance of efficiency and flexibility, and easy maintenance. These models are suitable for loading and unloading in sand and gravel yards, aggregate transfer at concrete mixing plants, rural infrastructure construction, and earthwork projects at small and medium-sized construction sites.

3.Large mining groups, port operating companies, construction engineering enterprises, and large logistics groups are advised to select large loaders with a rated load capacity of 6–12 t, such as the 966 and 980H models, which feature high load-bearing capacity, excellent reliability, and compatibility with continuous heavy-load operations. These loaders meet the demands of ore transfer in mines, bulk cargo loading/unloading at ports, large-scale infrastructure projects (e.g., highways, hydropower stations), and open-pit coal mining operations.
