Excavator Long Reach Arm CAT320 18Meters Hotsale in South East Asia Long Arm , Excavator Long Boom 18M

The CAT 320C long reach excavator with an 18-meter arm is a specialized machine designed for extended reach applications such as dredging, deep excavation, slope trimming, and demolition. Here are the key details about this configuration:

Key Features of CAT 320C with 18m Long Reach Arm

Extended Reach

The 18-meter (59-foot) long front allows digging and lifting at greater distances compared to standard excavators.

Ideal for deep trenches, riverbank work, and demolition where standard arms can't reach.

Engine & Performance

Operating weight: ~22–25 tons (varies with configuration).

Hydraulic system optimized for smooth long-reach operation.

Stability & Counterweight

Requires additional counterweight (up to 3–4 tons extra) to balance the long arm.

Wider tracks or outriggers may be used for stability on soft ground.

Attachments

Compatible with long-reach buckets (narrower and lighter than standard buckets).

Can also use grapples, shears, or hydraulic hammers for demolition.

Applications

Dredging & Waterway Maintenance

Deep Excavation (e.g., ponds, foundations)

Demolition (high-reach buildings)

Slope Grading & Landscaping

Comparison to Standard CAT 320C

Feature Standard 320C 320C Long Reach (18m)

Dig Depth ~6–7m ~10–12m

Reach at Ground ~9–10m ~16–18m

Bucket Size 0.8–1.2 m³ 0.3–0.6 m³ (lighter)

Counterweight Standard Extra (3–4T)

Considerations Before Buying/Renting
