Crawler excavators SZ260 with diesel-electric hybrid drive are ready for shipment abroad

Standard inspection procedures ensure the quality of exported hybrid excavators

The SZ260 crawler excavators with diesel-electric hybrid drive, prepared for loading, are custom models purchased by foreign clients in the infrastructure construction sector. All units undergo standard factory inspection before being loaded into containers and shipped to construction sites in Central Asia. The shipping team performs a series of inspection procedures: external inspection, verification of the synchronous operation of the diesel-electric hybrid system, leak testing of the crawler undercarriage, and calibration of the cab's electronic control system. This ensures that the SZ260 hybrid excavators meet the demanding operating conditions abroad.

Unlike conventional crawler excavators with a single drive type, the SZ260 model with a diesel-electric hybrid drive allows free switching between diesel and electric operating modes. Before loading, specialists simulate two operating scenarios: operation from a stationary power supply and autonomous operation at sites without access to the power grid. This allows checking the smoothness of mode switching and reducing the complexity of technical maintenance for end users. A complete set of technical inspection documents is supplied with the machines for acceptance abroad and subsequent service maintenance.

Main production and hybrid technologies of the SZ260 diesel-electric crawler excavator

Comprehensive technical assembly process of the diesel-electric hybrid system

The SZ260 crawler excavator with a diesel-electric hybrid drive is produced on well-established hybrid equipment assembly lines featuring a separate drive structure. The diesel power unit is designed for long-distance travel and open earthwork operations without access to the power grid. The external electric motor is suitable for low-emission operations: tunnel construction, work on production sites, and inner-city construction projects. Modular assembly is used in production: hydraulic pipelines, electrical wiring, and energy recovery units are manufactured separately and then integrated into the overall structure. This reduces assembly errors and improves equipment operational stability.

The machine is equipped with hydraulic energy recovery units. The kinetic energy generated during platform rotation and boom lowering is converted into electrical energy, supplementing the electric drive and reducing energy consumption. The entire hybrid drive control system is tuned for different operating conditions, compatible with voltage standards of many countries, and meets global emission regulations. This is a medium-sized crawler excavator suitable for various construction tasks abroad.

Application areas of the SZ260 diesel-electric hybrid crawler excavator on overseas projects

Flexible mode switching to meet the needs of global infrastructure construction

Foreign buyers choose the SZ260 crawler excavator with diesel-electric hybrid drive mainly due to the versatility of its two operating modes. The diesel mode is suitable for open-pit earthworks, quarry excavation, and road construction. The electric mode operates more quietly and produces no exhaust emissions, making it ideal for urban utility renovation, indoor demolition, tunnel development, and landscaping projects with strict environmental restrictions.

This hybrid crawler excavator is compatible with customized attachments: hydraulic breakers, grapples, and buckets for water body cleaning. The equipment is suitable for earthworks, demolition, and sorting of bulk materials. This large shipment includes original consumable parts, multilingual operation manuals, and remote technical support. We provide a comprehensive solution for equipment commissioning to overseas partners.

Consistent supply of hybrid construction machinery to expand the global market for eco-friendly equipment

In the global infrastructure industry, demand for low-carbon machinery is rising, making diesel-electric hybrid crawler excavators popular among overseas buyers. In addition to the SZ260 diesel-electric hybrid crawler excavator, we have various hybrid crawler and wheeled excavators of different weights in stock. Custom manufacturing is available with tailored drive configurations and attachments to meet specific project requirements.

This batch of SZ260 excavators is one of many overseas deliveries of hybrid machinery this year. Through standardized production, a comprehensive export logistics system, and long-term service support, we consistently supply energy-saving earthmoving equipment to global contractors. Our machinery helps overseas construction projects reduce long-term operating costs and comply with local environmental construction regulations.
