In intelligent logistics systems, the lifting component of an AGV directly determines its ability to handle heavy loads and ensure safety. As a core functional module, scissor-type and lead screw-type lift platforms work synergistically with the baseplate load-bearing system, lifting transmission mechanisms, and intelligent control boards to achieve precise vertical movement and positioning of heavy objects. This article provides an in-depth analysis of the design principles and selection criteria for these two mainstream lifting mechanisms, empowering enterprises to optimize AGV performance.

Lifting Mechanism: The “Core Joint” for AGV Heavy-Duty Handling

The AGV lifting component serves not only as the physical load-bearing unit but also as the critical actuator linking the navigation system to operational tasks. Its core consists of three parts:

1.High-Strength Baseplate: Directly supports heavy loads (e.g., automotive battery packs, machine parts), requiring impact and deformation resistance. Materials typically include manganese steel or aluminum alloy.

2.Scissor/Lead Screw Transmission Mechanism: Converts motor torque into vertical lifting force. Scissor lifts rely on hinge expansion, while lead screw lifts drive motion via nut linear movement.

3.Integrated Control Board: Monitors height and load status in real-time, communicates with the AGV main controller, and enables speed adjustment and emergency stop protection.

Typical Scenario: In automotive assembly lines, lifting 3-ton battery packs for precise docking (±1mm accuracy) with vehicle bodies, while resisting motion impacts of 15mm/s².

Scissor Lift Platform: Preferred for Long-Stroke Heavy-Duty Handling

Structural Features & Advantages

Scissor mechanisms achieve lifting through multi-layer cross-arm expansion, emphasizing force transmission efficiency and stability:

Load Capacity: Rated loads exceed 3 tons. Arms use rectangular manganese steel tubes (e.g., Q345B) with reinforced anti-deformation designs at hinge points.

Stroke Range: Lifting heights of 0.8–1.5m (common for AGVs), extendable up to 6m.

Drive Method: Hydraulic cylinder (traditional) or ball screw (modern), with the latter eliminating hydraulic leakage risks for enhanced sustainability.

Typical Applications

Ideal for automotive engine assembly and warehouse pallet transfer where large height adjustments are needed. Its foldable structure compresses initial height to 600mm, saving AGV chassis space.

Lead Screw Lift Platform: Synonymous with Precision & Self-Locking Performance

Technological Breakthroughs & Value

Lead screw mechanisms convert rotary to linear motion, achieving “zero-drift” self-locking through lead angle design:

Precision Control: Repeatable positioning accuracy of ±1mm, far surpassing hydraulic systems.

Self-Locking Reliability: When lead angle λ < equivalent friction angle ρ′ (e.g., λ=3.77°, ρ′=5.33°), position is maintained during power loss without additional brakes.

Efficiency Gains: Ball screw transmission efficiency reaches 80%, reducing energy consumption by 50% compared to trapezoidal threads.

Innovative Design Case

A patented solution optimizes torque output via gear reducers while limiting screw transmission efficiency to <50%, ensuring self-locking while minimizing motor power consumption and extending AGV runtime.

Key Selection Parameter Guide: Matching Scenario Requirements

Selection must balance load, precision, and environmental factors to avoid “over-engineering” or “underperformance”:

Other Critical Considerations:

Power Configuration: 48V lithium battery; motor power 1.1–1.5kW (2733N·mm torque required to lift 1 ton).

Structural Protection: IP54 dust/water resistance, anti-vibration design (especially scissor pin lubrication and screw dust covers).

Control Compatibility: CAN bus communication; real-time height feedback via integrated displacement sensors.
