In modern airport baggage handling systems, baggage security screening and transportation are vital components. These systems must ensure the safety and security of passengers' baggage while guaranteeing its smooth transport to the intended destination. The following section introduces the main components of baggage security screening and transport systems, as well as the role of motorized pulleys (drum motors) within them.

Baggage Security Screening System
The security screening system is inextricably linked with the baggage system. Its purpose is to allow security screeners to inspect and evaluate baggage without halting the conveyor line. Depending on the screening method used, the role of the security screening system within the overall baggage system varies:
1. Dual-Channel Stratified Management Mode:
- Pros: On-site inspection/opening at the check-in area, mature security procedure, moderate investment.
- Cons: Takes up public space, slow speed, high equipment count, suboptimal explosion-proof inspection effectiveness.
2. Five-Level Centralized Screening Mode:
- Pros: Reduces the number of bags needing to be opened, improves check-in counter efficiency, reduces public space usage.
- Cons: Delayed bag opening, requires a dedicated inspection room in the airside/sterile area, complex system, high investment, expensive maintenance.
3. Three-Level Centralized Screening Mode:
- Pros: Relatively reduces bag opening, high check-in counter efficiency, relatively lower investment.
- Cons: Requires locating passengers, creates crossing passenger flows, increases baggage system complexity, poor equipment competitiveness, high maintenance costs.

Baggage Transport System
The baggage transport system covers outbound, arrival, and transfer operations to ensure baggage reaches its destination smoothly.
- Outbound Baggage System: Includes baggage sorting, early bag storage (EBS), oversized baggage handling, and empty tub/tray recycling.
- Arrival Baggage System: Ensures baggage is accurately delivered to the passenger baggage claim area.
- Transfer Baggage System: Transfers the baggage of connecting passengers from one flight to another.
How to Choose the Right Motorized Pulley (Drum Motor) Model in Airport Baggage Handling Systems
Drive Units for Baggage Conveyor Equipment: Motorized pulleys serve as the drive units in baggage handling systems for continuous and high-density baggage flows, delivering bags to designated locations quickly and accurately. Whether moving bags from security lanes to departure gates or from aircraft to baggage claim, motorized pulleys complete the transport process in a short time, boosting overall baggage handling efficiency.
Model Characteristics: The TM80A (TM113A), TM138A, and TM165H motorized pulley models are all suitable for security screening machines and airport baggage handling systems. Each features distinct characteristics and application ranges:
- TM80A / TM113A:
These models feature high power output and low noise, making them suitable for conveyor equipment with high demands for noise control, drive space, and power. In airport baggage systems, they are widely used in passenger-facing areas and near security screening lanes to reduce noise pollution and improve traveler comfort.
- TM138A:
Featuring high efficiency, high power output, and smooth operation, the TM138A model is ideal for medium-load belt conveyor equipment. As medium-load conveyors form the core of the baggage transport system, this model enhances operational efficiency and system stability.
- TM165H:
Designed for heavy-load belt conveyors, this model delivers high efficiency, high power output, and exceptionally smooth performance. It is particularly suited for large-scale security screening equipment and logistics inspection systems handling heavy loads, ensuring safe transport and meeting strict airport requirements.

The application of motorized pulleys not only improves the efficiency and security of baggage handling, but also offers passengers peace of mind during travel, providing reliable operational support for airports.
