6-ton crawler excavator is a medium and small-sized construction machinery that combines flexibility and operational efficiency. It has stronger power than micro excavators (1-3 tons) and is more suitable for narrow sites than medium-sized excavators (over 10 tons). It is widely used in municipal works, farmland water conservancy, building foundation construction and other fields, and is the main model for small and medium-sized engineering projects.

Core characteristics

1. Motivation and operational ability

Engine: Equipped with a 35-45kW (approximately 48-60 horsepower) diesel engine (such as Yanmar, Isuzu, Cummins), it meets the National IV emission standards, with a fuel consumption of about 4-6L/h.

Hydraulic system: It adopts a dual-pump and dual-loop load-sensitive hydraulic system, which provides more precise flow control. It can simultaneously operate the boom, bucket rod and rotation actions, increasing efficiency by more than 20%.

Mining performance:

Standard bucket capacity: 0.2-0.28m³

Maximum excavation depth: 3.5-4.2 meters

Maximum excavation radius: 5.8-6.5 meters

Bucket digging force: 40-50kN (approximately 4-5 tons of force)

2. Structure and Stability

Track design

Standard steel tracks (rubber tracks are optional), with a low ground contact pressure (30-40 kpa), and strong passability in wet and muddy areas.

Some models are equipped with retractable chassis (such as Sany SY60C), and the track width can be adjusted to 1.5-1.8 meters to enhance slope stability.

Working device:

Reinforced boom and boom, suitable for heavy-load excavation.

An optional extended arm (4.5-5 meters) can be installed for deep trench operations.
