Lift AGV Safety Technologies | Anti-Collision, Auto-Leveling & Positioning

Safety is one of the most decisive factors when integrating AGVs into a production or warehouse environment. A Lift AGV doesn’t just move materials—it operates in shared spaces with workers, forklifts, machinery, and conveyor systems. Its vertical lifting mechanism introduces additional safety considerations related to balancing, load stability, and docking accuracy.

To address these challenges, AOTENENG designs its Lift AGVs with multiple layers of intelligent safety technologies, ensuring smooth, predictable, and reliable operation in even the most demanding environments.

These safety systems form the foundation of a truly autonomous logistics workflow, allowing factories to increase automation without compromising personnel or equipment safety.

Lift AGV – Technical Specifications

360° Anti-Collision and Obstacle Detection

AOTENENG Lift AGVs use industrial-grade LiDAR sensors to provide full 360° detection coverage.
This enables the AGV to:
• Identify objects, humans, or forklifts in its path
• Automatically slow down when proximity is detected
• Stop safely before impact
• Dynamically adjust routes based on obstacles

Side-mounted sensors provide additional protection in narrow aisles where objects may approach from low angles or blind spots.
The AGV’s anti-collision logic is tuned for smooth deceleration, preventing sudden stops that may destabilize lifted loads.

Auto-Leveling for Safe Vertical Lifting

Vertical lifting introduces risk if the platform tilts or becomes unstable under uneven loads.
AOTENENG addresses this with a built-in auto-leveling system that includes:
• Real-time load balance detection
• Synchronized lifting algorithms
• Multi-point support for platform stability
• Automatic speed adjustment during elevation

This ensures that even tall or top-heavy loads remain balanced during lifting and lowering operations.
Auto-leveling also protects conveyor-top modules from alignment errors caused by uneven load distribution.

High-Precision Position Detection for Station Docking

Docking accuracy is critical when interfacing with conveyors, robotic stations, or production equipment.
AOTENENG Lift AGVs use a combination of:
• Laser rangefinders
• QR codes or markers
• Vision-assisted positioning
• Wheel encoder feedback
• Height-position sensors

These systems allow the AGV to stop within ±5 mm tolerance, ensuring perfect alignment during loading and unloading.
This high precision dramatically reduces collisions with conveyor edges, station fixtures, and machine guarding.

Overload and Anti-Drop Protection Systems

Lifting mechanisms must be protected against misuse or unexpected load conditions.
AOTENENG integrates multiple layers of lifting safety, including:
• Overload detection with automatic lift-lock
• Anti-drop mechanical locks
• Lifting speed limiters under heavy load
• Automatic descent control in emergencies
• Real-time torque monitoring

These protections ensure safe operation even if the load exceeds planned weight or the platform experiences sudden resistance.

Dynamic Speed Control for Safe Navigation

AGV speed must adapt to environmental conditions to prevent tip-over and ensure safe lifting.
AOTENENG Lift AGVs automatically adjust speed based on:
• Load weight
• Lifting height
• Curves and turning angle
• Human presence in the area
• Narrow aisle detection

For example, when the platform is raised, the AGV enters a safe-speed mode to ensure stability until the lift is fully lowered again.

Intelligent Warning and Status Alerts

To enhance on-site safety awareness, the AGV provides real-time audio-visual alerts, including:
• LED status lighting
• Movement direction indicators
• Audible warnings during lift operations
• Fault or emergency alerts
• Station docking confirmation signals

These notifications ensure operators, technicians, and nearby personnel always understand AGV movement intentions.

Fail-Safe Electrical and Emergency Systems

AOTENENG Lift AGVs incorporate industrial-grade electrical safety including:
• Emergency-stop buttons
• Circuit-level short-circuit protection
• Battery safety monitoring (overheating, voltage control)
• Redundant braking systems
• Dual-channel safety circuits

The AGV is built to safely shut down or stop lifting if any anomaly is detected.

Safety as a Core Design Philosophy

Instead of adding safety as an afterthought, AOTENENG designs its Lift AGVs around safety from the ground up—including frame strength, load balance, electrical architecture, and navigation logic.

This ensures customers receive a reliable, industry-compliant solution capable of operating safely in fast-paced, shared environments.
