1 ton crawler excavator

A 1-ton crawler excavator is an ultra-small crawler-type construction machinery. Although it is small in size (with a body weight of about 1 ton, usually 2-3 meters in length, 1-1.3 meters in width, and 1.5-2 meters in height), it plays an important role in small-scale projects, field operations, and scenarios with low requirements for ground pressure, relying on the stability of crawler travel and adaptability to complex terrain. Its core advantages are "strong adaptability to terrain and good operational stability". The following are the specific applicable fields and functional characteristics:

I. Core Applicable Scenarios and Operation Contents

1. Small-scale Agricultural and Rural Operations

• Farmland and Orchard Operations:
• Digging fertilizer trenches for fruit trees (30-60 cm deep) and transplanting pits for old trees in hilly and mountainous orchards. The crawler can walk stably on slopes (slope ≤ 25°) to avoid slipping.
• Tilling and ridging small farmlands (width ≤ 1 meter), especially on muddy land after rain. The crawler has a large ground contact area (pressure about 0.2-0.5 MPa), so it is not easy to get stuck, replacing cattle plowing or manual hoes.
• Digging small drainage ditches in paddy fields and vegetable fields to solve waterlogging problems. The crawler has little impact on the compaction of soft field surfaces.
• Auxiliary Rural Infrastructure Construction:
• Excavating foundations and leveling subgrades for rural roads, or repairing small collapse sections, which can work directly on dirt roads and gravel grounds.
• Shallow excavation of foundations (depth ≤ 1 meter) and finishing of apron slopes for rural houses, suitable for homestead scenes without hardened roads.

2. Field and Non-hardened Site Engineering

• Small Earthwork and Excavation:
• Leveling small sites in mountains and woodlands (such as foundations for simple sheds) and cleaning firebreaks (excavating surface vegetation and tree roots).
• Dredging the banks of rivers and ponds (excavating silt in shallow water areas, where the crawler can work stably on slippery banks) and reinforcing small embankments (transporting sand and gravel for filling).
• Low-load Crushing Operations:
• Demolishing walls of abandoned houses in the field (with a breaker attachment) and crushing old stone slab roads. Supported by the crawler, the machine body vibrates little, and the crushing accuracy is controllable (suitable for concrete or stones with a thickness ≤ 10 cm).

3. Fine Excavation and Cleaning of Small Sites

• Operations in Narrow Non-hardened Sites:
• Digging small septic tanks (1-2 meters in diameter, within 1.5 meters in depth) and seepage wells in urban villages and rural courtyards. The narrow body can pass through small courtyard gates (width ≥ 1 meter).
• Cleaning manure pits in farms and crushing foundations before ground hardening. The crawler can walk stably on fecal-contaminated and muddy ground without slipping.
• Cleaning of Ruins and Wastes:
• Excavating bricks and concrete blocks at small demolition sites (non-indoor scenes), cooperating with small tractors for transportation. The crawler can work on gravel piles.
• Cleaning debris (such as tree roots and stones) in field campsites and temporary construction sites to level out small activity spaces.

4. Small-scale Garden and Landscape Engineering

• Outdoor Landscape Renovation:
• Digging small lakes (area ≤ 50㎡) and building rockery foundations in parks and scenic spots. Although the crawler will slightly roll the surface when walking on grasslands and woodlands, it is more suitable for non-hardened sites than wheeled ones.
• Finishing slopes (such as slopes of community green belts) and digging vegetation planting pits. The climbing ability of the crawler ensures stable operation on inclined ground.
• Auxiliary in Nurseries and Forest Farms:
• Digging seedling transplanting pits and laying irrigation ditches in nurseries. The crawler compacts the soil moderately and does not affect the growth of seedling roots.

III. Limitations and Precautions

• Scene Limitations: Due to the fact that crawlers are easy to get stuck with mud and the body width is slightly larger than that of wheeled ones, they cannot enter indoor spaces (such as corridors and shops) or narrow doorways (width < 1 meter), nor are they suitable for operations on hardened roads (such as asphalt roads and indoor floor tiles), otherwise the ground will be scratched.
• Load Limitations: As an ultra-small equipment, it has limited digging force (bucket capacity is usually ≤0.1 cubic meters), and is not suitable for long-term crushing of thick concrete (thickness > 15 cm) or transporting heavy materials (such as large stones).
• Maintenance Points: The crawler needs to be cleaned of mud regularly to avoid wear of the crawler plates; after working in the rain, the tightness of the crawler should be checked to prevent falling off.
