- Heavy-Duty Performance: Rated load capacity of 5000kg, supported by Siemens stepper motor and PLC control for stable operation.
- Space-Efficient Installation: Requires a 5100mm diameter space with 700mm pit installation, ensuring a flush floor integration.
- Smart Control & Safety: Features a 10-inch touch panel, emergency stop, overload protection (current relay), and one-click reset/auto-recovery functions.
- Adaptability: Operates in temperatures from -20°C to 60°C, suitable for indoor unmanned vehicle testing and prototype calibration.
Project Overview
The client is a leading smart logistics and supply chain solutions company in China.
This system utilizes a servo motor for high-precision rotation, primarily applied in two phases of unmanned vehicle manufacturing: first, during the post-production testing phase, and second, in the design phase for calibrating the first prototype vehicle.
The Challenge
Precision in Heavy Loads: Maintaining ≤±4mm flatness and ≤±3mm roundness under 5000kg dynamic loads.
Complex Installation: Ensuring seamless pit installation (700mm depth) with precise alignment to avoid ground-level discrepancies.
Temperature Resilience: Guaranteeing stable performance across extreme temperatures (-20°C to 60°C).
User-Friendly Operation: Simplifying complex controls (adjustable speed/angle/step) for technicians during vehicle testing.
Safety Compliance: Preventing mechanical failures during emergency stops or overload scenarios.
Solutions
Robust Structural Design:
Reinforced steel frame with surface treatment (spray painting/coating) to resist wear and environmental stress.
Precision-ground bearings and Siemens stepper motor for smooth step rotation (±0.5° error control).
Advanced Control System:
PLC integration with a 10-inch touch panel for customizable speed (1–6 min/rotation), angle (10° increments), and step intervals.
Real-time feedback via sensors to ensure flatness/roundness compliance.
Thermal Management:
Components rated for wide temperature ranges (-20°C to 60°C), with heat-resistant wiring and lubrication.
Safety Mechanisms:
Dual-layer protection: emergency stop button + overcurrent relay for instant shutdown during overloads.
Programmed smooth start/stop to minimize inertial stress on heavy loads.
Modular Installation:
Pre-fabricated pit mounting system to streamline on-site assembly and alignment.
Advantages
Unmatched Precision: Critical for calibrating unmanned vehicle prototypes and post-production testing.
High Load Capacity: Supports 5-ton loads with 464kg/m² ground pressure, ideal for industrial applications.
Operational Flexibility: Adjustable speed (0.167–1r/min), step angles, and ±360° rotation enable tailored testing scenarios.
Durability & Safety: Siemens motor reliability, overload protection, and emergency stops ensure long-term, risk-free operation.
Ease of Use: Intuitive touch panel and one-click functions reduce training time for technicians.
