Core Technical Advantages
Intelligent Remote Control for Precision and Efficiency
- Utilizes advanced single-rope wireless remote control technology, eliminating limitations of traditional mechanical operation. Enables remote precision handling, effectively reducing labor costs and safety risks.
- Supports multi-mode switching, allowing flexible adjustment of grab opening/closing speed and force based on material properties (e.g., density, granularity), ensuring operational stability and efficiency.
High-Capacity Design Adapting to Diverse Needs
- Flexible bucket capacity: standard capacity covers 3-15 m³ at a 25° angle of repose, with variable capacity up to 6-30 m³, meeting loading demands for various materials (e.g., ores, coal, aggregates).
- Powerful lifting capability: full range of 16-50 ton specifications, compatible with diverse crane equipment, effortlessly handles heavy-load material handling scenarios.
Robust and Durable with Extended Lifespan
- Main structure uses high-strength alloy steel treated with rigorous impact/corrosion resistance processes, suitable for harsh conditions (humidity, dust, high temperatures).
- Critical components (e.g., closing ropes, pulley sets) employ internationally renowned brand parts. Combined with precision machining, this ensures long-term stable operation and reduced maintenance frequency.
