1.2 Tonne Excavator

The WK12 1.2-ton excavator, with an operating weight of 1200kg, stands as an ideal choice for small-scale engineering operations. Its compact design and precise performance make it particularly suitable for scenarios such as municipal maintenance, courtyard renovation, small infrastructure projects, and agricultural assistance. It can operate flexibly in narrow spaces while meeting the core needs of light digging and handling tasks.

Core Performance and Configuration

• Digging Equipment: Equipped with a bucket with a capacity of 0.018 cubic meters and a width of 400mm, the bucket’s optimized curvature enables efficient loading of bulk materials like soil and gravel. Combined with stable hydraulic control, it ensures precision and continuity during operations.

• Power System: The standard configuration includes a KOOP192 engine with air-cooled heat dissipation, delivering a rated power of 7KW. It provides stable power output and can adapt to long-hour operation requirements. For higher power needs, the Kubota D722 engine is available as an option, with power increased to 10.2KW, further enhancing the equipment’s driving force in complex working conditions.

• Mobility and Passability: The chassis width is 934mm, paired with 180mm-wide tracks, resulting in a reasonable ground contact area that maintains good grip on soft ground or slopes. The minimum ground clearance reaches 197mm, far exceeding that of similar models, allowing it to easily cross ground obstacles such as stones and bumps and reducing the risk of chassis collisions. With a travel speed of 2.1km/h, it balances controllability during operations and efficiency during transfers.

• Working Range: Despite being a small model, it boasts comprehensive operational coverage:

• A maximum digging height of 2283mm, meeting the needs of high-altitude operations such as wall foundations and fence pits.

• A maximum unloading height of 1698mm, facilitating the transfer of materials to light trucks, hoppers, and other containers.

• A maximum excavation radius of 2507mm, combined with a flexible boom design, enabling coverage of a wide area without frequent movement of the machine body.

• Both the maximum digging depth and vertical digging depth are 1436mm, sufficient for deep operations such as small drainage ditches and foundation trenches. Moreover, the verticality control during vertical digging is precise, reducing post-operation trimming work.

• Operational Flexibility: With a minimum turning radius of 1371mm and a turning speed of 3000rpm, it can quickly adjust the working direction in narrow spaces (such as indoor renovations and roadway construction), minimizing the constraints of space limitations. It has a maximum climbing capacity of 15°, suitable for operations in gently sloping areas. Combined with the anti-slip design of the tracks, it ensures stability during slope operations.

• Hydraulic System: Operating at a pressure of 16MPa, the hydraulic pipeline layout is compact, enabling efficient power transmission. This makes the movements of the bucket and boom responsive and smooth, reducing energy loss during operations and improving the efficiency of single-cycle operations.

Optional Configurations

To adapt to diverse scenarios, the WK12 offers a range of optional features:

• Swing boom: Allows lateral offset operations, providing greater flexibility when working near wall edges or obstacles.

• Telescopic tracks: By adjusting the track width, it further enhances the equipment’s passability in narrow spaces or stability on soft ground.

• Enclosed cabin: Equipped with a windproof, rainproof, and sunproof enclosed structure, it provides operators with a more comfortable working environment, especially suitable for long-hour outdoor operations or use in dusty and rainy areas.

In summary, the WK12 1.2-ton excavator, with its balanced performance, flexible configurations, and reliable durability, provides an efficient solution for small-scale engineering operations. Both professional construction teams and individual users can benefit from a tailored operational experience.
