2. Key Technical Advantages

(1) High-efficiency & Low-consumption Power System

Equipped with an internationally renowned Kubota high-pressure common rail turbocharged engine, its fuel combustion efficiency is optimized by the intelligent electronic control system, which reduces comprehensive fuel consumption by 7~10% compared with products of the same tonnage class. It supports normal cold start at -20℃ without auxiliary devices, and runs stably at an altitude of 3000m, adapting to extreme construction environments such as high cold and plateau.

(2) Precise & Smooth Hydraulic System

Adopts imported load-sensing full hydraulic control system, which realizes accurate power matching of the main pump, control valve and actuator. Composite actions (boom lifting, arm pulling, upper structure swing) run coordinately without lag, and the operation accuracy is 12% higher than similar products. The reserved extended hydraulic interface supports quick replacement of multiple attachments (hydraulic breaker, log grapple, auger, ripper, etc.) to meet diversified operation demands.

(3) Super Durable Structural Design

The boom, arm and bucket are made of high-strength Q355B structural steel, which has passed 10,000 hours of extreme working condition fatigue test. The reinforced X-type undercarriage, heavy-duty track chain and support rollers greatly improve the impact resistance of the whole machine, extending the service life of structural parts by more than 20% under harsh working conditions such as quarries and demolition sites.

(4) Comfortable & Safe Operating Environment

The cab is certified by ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure), with fully sealed noise reduction design, and the internal operating noise is lower than 75dB(A). It is equipped with a multi-directional adjustable air suspension seat, large-area dustproof air conditioning system, and a 7-inch high-definition LCD monitor that displays real-time operating parameters, greatly reducing the work intensity of operators during long-time construction.

(5) Intelligent Operation Management

Equipped with Sunward's self-developed IoT intelligent management platform, equipment managers can remotely check the real-time location, fuel consumption, working hours and operating status of the excavator through mobile APP or PC terminal, realize active fault warning and remote diagnosis, which reduces equipment maintenance cost by 15% and improves fleet management efficiency.

3. Main Application Scenarios

As a multi-functional small and medium-sized excavator, the SWE90 series is widely used in:

Municipal engineering: road repair, underground pipeline laying, sidewalk construction
Agricultural and forestry construction: land reclamation, irrigation ditch digging, orchard planting, forest land clearing
Urban renewal: old building demolition, indoor renovation, construction waste removal
Small water conservancy and mining projects: quarry auxiliary operation, small reservoir dredging
Narrow space construction: tunnel operation, underground garage construction, etc.

4. After-sales Service Support

Sunward has built a global after-sales service network:

In the domestic Chinese market: more than 200 local service outlets provide 24-hour on-site response, core parts are guaranteed for 1 year or 2000 working hours.
In overseas markets: more than 30 regional spare parts warehouses and service centers have been set up in Southeast Asia, Europe, North America, Africa and other regions, providing localized technical support, maintenance and spare parts supply services for global users.

With reliable performance, high cost performance and low operation cost, the SWE90 series has become one of the most popular 9-ton excavator products in the global market, with cumulative sales exceeding 12,000 units worldwide by 2024.
