Core Technical Advantages
- Millimeter-Level Precision Positioning
Equipped with high-precision laser scanners and absolute encoders, it achieves 3D scanning modeling and automatic material location recognition. Positioning and repeatability accuracy are controlled within 5 millimeters, ensuring precise and error-free grasping and unloading points, meeting the fine-grained operational demands of complex material piles. - Full-Scene Unmanned Operation
Supports triple control modes—remote central control, cab operation, and wireless remote control. Operators can complete entire tasks from offices up to 1000 meters away, completely avoiding harm from harsh conditions like high temperatures, dust, and strong corrosion while significantly reducing labor intensity. - Intelligent Safety Protection
Equipped with nine protective functions including short-circuit, overload, and hoist limit switches. Integrated with an intelligent sensing system that detects obstacles in the travel path in real time, automatically executing stop-and-avoid maneuvers or path adjustments. The hoist mechanism and electrical control system feature redundant designs, ensuring operational reliability under high-load conditions. The machine’s Mean Time Between Failures (MTBF) outperforms the industry average by 22%. - High-Efficiency Energy Adaptation
Utilizes variable frequency speed control technology and optimized transmission structures to achieve smooth starts/stops and precise speed regulation, effectively reducing mechanical losses and energy consumption. Automatically distributes materials based on silo levels, boosting operational efficiency by over 20% compared to traditional models. Seamlessly integrates with enterprise MES production execution systems and DCS control systems to enable intelligent production line coordination.

Your Top Questions About Henan Mine manufactured Unmanned Grab Crane and Professional Answers
-
Can the positioning accuracy of this unmanned grab crane be consistently maintained?Professional Answer: Absolutely. The equipment employs triple positioning technology combining “laser scanning + absolute encoders + PLC closed-loop control.” The laser scanner performs real-time sector scanning of material piles to generate 3D models, while absolute encoders precisely record operational trajectories. Coupled with optimized dynamic control algorithms, this ensures long-term positioning accuracy remains consistently within 5 millimeters.
-
How is operational safety ensured in unmanned mode?Professional Answer: Safety safeguards are integrated throughout the entire equipment design process. Proactive protection features include an intelligent sensing system that continuously monitors the work area, identifies personnel, equipment, and other obstacles, automatically stops the crane, and triggers alarms while simultaneously activating on-site security systems. Additionally, the equipment incorporates nine major safety protection functions—including short-circuit, overload, and over-temperature protection—to comprehensively cover various emergency scenarios.
-
Is it difficult to integrate this equipment with enterprise management systems like MES or TOS?Professional Answer: The equipment offers exceptional adaptability, fully compatible with existing production line requirements. First, parameters can be customized for specific site conditions, with optional upgrades for high-temperature, high-dust, or high-salt-fog environments. Second, the system includes standardized communication interfaces.
-
Are maintenance costs high? What are the key points for routine maintenanceProfessional Answer: Maintenance costs are over 30% lower than traditional models, and full-time technical personnel are not required. Core daily maintenance involves inspecting safety switches and braking systems. Maintenance procedures are standardized and accompanied by detailed operation manuals.
-
How much does unmanned operation improve efficiency?Professional Answer: Efficiency gains are significant, with overall operational efficiency increasing by 20%-30% compared to manual operation. The unmanned system enables 24/7 continuous operation without downtime, eliminating fatigue-related efficiency drops in manual labor. Benefits include increased production output, reduced material waste, and lower maintenance costs.
-
Can the equipment operate normally in extreme environments like low or high temperatures?Professional Answer: Customized solutions can be tailored for extreme environments, fully meeting -30°C low-temperature operation requirements. For high-temperature conditions, the equipment will be equipped with forced cooling systems and high-temperature resistant coatings to ensure normal operation at 60°C.
