COMPACT EXCAVATION PLATFORM / SINN1.8T

Product Overview

The 1.8 ton mini excavator SINN1.8T is a modular mini crawler excavator platform for buyers who require narrow-access maneuverability and dependable daily excavation performance in one machine. The platform combines a compact upperstructure, rubber tracks, pilot-controlled hydraulics and two retractable undercarriage configurations for landscaping, trenching and utility-focused work.

Configuration A pairs the Kubota D722-E4B engine with a 1000–1350 mm undercarriage for a wider working stance. Configuration B pairs the Kubota D902 engine with a 990–1300 mm undercarriage for narrow-access priority and additional engine power reserve. Final configuration should be selected according to access width, attachment package, emissions requirements and expected duty cycle.

Frequently Asked Questions

Which SINN1.8T Configuration Is Best for My Jobsite and Market?

The D722-E4B configuration with a 1000–1350 mm retractable undercarriage is suited to fuel-conscious daily operation and a wider working stance. The D902 configuration with a 990–1300 mm undercarriage is suited to tighter access and additional engine power reserve. Final selection should consider access width, attachment package, emissions requirements and duty cycle.

What Is the Installed Machine Output?

The specification sheet states installed machine output at the governed 2300 rpm operating speed: 10.3 kW for the D722-E4B configuration and 11.8 kW for the D902 configuration. These figures differ from gross industrial engine ratings published at higher rated speed. Applicable engine datasheets are available during quotation.

What Attachments Can This 1.8 Ton Mini Excavator Support?

With a double-acting auxiliary hydraulic circuit rated at 33 L/min at 20 MPa, the machine can be matched with digging, trenching and grading buckets, hydraulic augers, hydraulic thumbs, quick couplers and light-duty hydraulic breakers. Final attachment matching should be confirmed according to flow, pressure, weight and application.

What Access Width and Transport Dimensions Should Buyers Confirm?

Buyers should confirm the required gate or access width against the selected retractable undercarriage: 1000–1350 mm for SINN1.8T-A or 990–1300 mm for SINN1.8T-B. Final transport dimensions depend on the selected canopy or cab, attachment configuration and packing plan and should be confirmed during quotation.

What Emissions, Safety and Loading Documentation Can Be Provided?

For applicable final configurations, SINN can provide available emissions labels, engine records, CE conformity documentation, operator-protection records and container-loading information required for the destination market. The document package depends on the selected engine, operator-station configuration, attachments, export destination and packing plan.
