Ascenseurs à mouvement alternatif parallèles de 5 tonnes dans une usine de production de carbone de Mongolie intérieure
Vue d'ensemble
This case analysis details the material handling solution for a “lights-out factory” in Inner Mongolia Autonomous Region.
To efficiently transport finished carbon blocks between two workshops with significant level differences at a fast production pace, two parallel reciprocating lifts were deployed.
Since commissioning on August 15, 2025, the system has operated reliably under high-frequency, heavy-duty conditions with zero production-impacting issues.

Comment ça marche
The system employs two parallel 5-ton capacity reciprocating lifts.
Finished carbon blocks are conveyed onto the lift car (2200x2200mm) via customer-supplied roller lines.
Photoelectric sensors detect the load, triggering a 22KW SEW gearmotor to lift the cargo vertically 5 meters at speeds up to 20 m/min.
After precise positioning, the blocks are discharged into the adjacent workshop, enabling fully automated, rapid inter-floor transportation.
Les défis
- Lights-Out Operation: Demanded extreme reliability and stability for fully automated operation with zero tolerance for downtime.
- Fast Production Pace: Required high efficiency and rapid response for very high daily cycles.
- Heavy-Duty Operation: 5-ton loads per cycle presented a significant challenge to structural integrity and the drive system.
- Contraintes spatiales: Limited installation area (3380x2900mm) required precise layout, with a fit gap in the car depth direction.
- Integration Needs: Required seamless communication and control integration with customer’s roller conveyors for a fully automated line.
Solutions
- Parallel Operation for Efficiency & Redundancy: Two lifts installed side-by-side meet the fast pace and provide backup during maintenance, ensuring continuous lights-out operation.
- Heavy-Duty Design: Utilized national standard steel components and an integrated car-lifting structure to ensure strength and long-term durability under 5000kg loads.
- Premium Core Components: A high-power 22KW SEW gearmotor provides robust and reliable power for high-frequency start-stop cycles.
- Multi-Layer Safety Protection:
Fall Prevention: Mechanical safety gear to fundamentally prevent car falling.
Protection contre les surcharges: Integrated sensor locks the system if overloaded.
Détection des cargaisons: Photoelectric sensors prevent oversized goods from causing jams.
Electrical Protection: Control system includes emergency stop, phase-loss protection, etc. - Flexible Integration: The PLC control system provides comprehensive communication interfaces and logic for easy integration with the customer’s conveyor system, enabling intelligent coordination.
