Description

JCB Backhoe Loader 3CX-ECO | 8.1 ton

The JCB 3CX ECO is a cornerstone of the backhoe loader market, specifically valued for its balance of power and fuel efficiency.
For the 8.1-ton configuration (often associated with the “Sitemaster” or “Plus” variants), the machine is designed for high-intensity digging and loading while maintaining a relatively compact footprint.
Below are the primary specifications for the 8.1-ton variant:

Feature Specification

Operating Weight 8,135 kg (approx. 8.1 tons).
Engine Model JCB EcoMAX (Stage V / Tier 4 Final compliant).
Engine Power 81 kW (109 hp) @ 2200 rpm.
Max Torque 516 Nm @ 1450 rpm.
Max Speed 40 km/h (standard) – up to 50 km/h with Autoshift.
Fuel Tank Capacity 150–160 Liters.

Performance & Excavation

The 3CX ECO is noted for its “EcoDig” system, which uses three hydraulic pumps to provide high pressure and flow at low engine speeds.
Max Dig Depth: 4.24 m (Standard) / up to 5.97 m (with Extradig telescopic handle).
Max Reach (at ground level): 5.37 m (Standard) / up to 6.52 m (Extradig).
Loader Bucket Capacity: 1.0 m3 to 1.3 m3 (depending on shovel type).
Shovel Breakout Force: 6,531 kgf.
Hydraulic Flow: 165 l/min peak flow.

Static Dimensions

Total Travel Length: 5.62 m.
Total Travel Height: 3.61 m.
Width (over bucket): 2.35 m.
Wheelbase: 2.17 m.
Ground Clearance: 370 mm.

Key Efficiency Features

TorqueLock: A unique system that locks the torque converter in high gears, reducing fuel consumption by up to 25% during road travel.
EcoLoad: Improves tractive effort and cycle times by controlling hydraulic speed at the loader end.
Auto-Idle: Automatically reduces engine RPM when the levers are not in use to save fuel.
Smooth Ride System (SRS): Actively reduces machine “bounce” when traveling with a full bucket, increasing load retention and operator comfort.
Note: Specifications can vary slightly based on the specific “Package” (e.g., Sitemaster vs. Contractor) and the year of manufacture. The 8.1-ton weight typically includes the 6-in-1 shovel and an extending dipper.
