The machine is equipped with a RATO R740-1 engine with a rated power of 15 kW and rated speed of 3600 rpm.
The engine provides the power required for driving, loading, and mixing operations, helping the machine maintain stable performance during continuous construction work. With a compact engine layout, it is suitable for small construction environments where equipment size and operational flexibility are important.
The 500L mixing system is designed for onsite concrete preparation with a total volume of 500 L and concrete output per batch of 320 L.
The integrated mixing structure allows operators to prepare concrete directly at the job site, reducing dependence on external concrete supply and improving flexibility for small construction projects.
Different from traditional wheeled equipment, the crawler chassis provides improved ground adaptability for uneven construction areas.
The crawler system helps the machine operate in challenging working conditions such as rural construction sites, rough ground, and areas where standard vehicles may have limited access.
The machine features a hydraulic loading bucket with a capacity of 0.1 m³, allowing operators to complete material loading operations with reduced manual handling.
The self-loading function improves workflow efficiency by combining loading and mixing processes in one compact machine, making it suitable for small construction teams and flexible jobsite operations.
The control layout is designed for convenient operation, allowing operators to manage driving, loading, and mixing functions from the operating position.
The compact design helps improve visibility and control efficiency, especially when working in confined construction areas.
Built for construction environments, the crawler self loading concrete mixer combines a compact structure with strong mobility.
The machine provides a practical balance between size, working capability, and transportation convenience for small-scale concrete projects.
Engineered for adaptability, our self-loading concrete mixers deliver high-quality concrete exactly where you need it, overcoming the limitations of traditional batching plants
