Process Overview
A multi-level shuttle is an automated storage and retrieval vehicle driven by AC or DC power. It runs on rack rails, retrieves totes with clamp-type forks, places them at designated exits, and stores incoming totes into assigned locations. Multi-level shuttle systems are evolving toward higher speed, greater complexity, and higher intelligence, with more flexible storage management and scalability. They are widely used in ecommerce small-item logistics, daily goods, pharmaceuticals, tobacco, beverages, packaged foods, production logistics, and order processing.
Scenario Pain Points
Low Speed
Most equipment in the industry still runs around 3 m/s. Customers need faster shuttle solutions that break the current performance bottleneck.
High Vibration
Inertia during transport can cause vibration, shifting or dropping totes and making storage and retrieval more difficult.
Difficult Maintenance
Shuttles operate in narrow, elevated, and complex spaces. Customers need an integrated and networked sensing solution that supports fault prevention and maintenance.
GATPOR Solution
1. Distance sensors
Because shuttles move inside automated warehouses, rack flatness and sensor reliability are critical. GATPOR distance sensors help equipment run stably, with 1-2 mm accuracy and speeds up to 10 m/s.
2. Photoelectric sensors
The PS series supports sensing distances up to 5 m, covering the width of high-bay racks. Optional visible-light models improve on-site visibility and make detection results easier to verify during installation and debugging.

Process Overview
In express sorting centers, cross-belt sorters are core equipment. Whether the mailbag at each chute is full directly affects sorting efficiency and parcel safety. Traditional manual inspection is inefficient and can miss timely bag replacement, causing overflow, mis-sorting, or parcel damage. With long-range, high-accuracy, and interference-resistant performance, laser sensors are becoming the intelligent eye for full-bag detection at sorter chutes.
Scenario Pain Points
Long-range Detection Needed
On multi-level cross-belt sorters, the sensor is far from the mailbag, so a diffuse-reflection photoelectric sensor with long detection range is required. Because parcels vary in color and shape, ordinary diffuse sensors often show large distance variation and unstable full-bag detection.
Visible Alignment Needed
The sensor spot needs to be clearly visible to support early installation and later detection visualization.
GATPOR Solution
GATPOR PS05 ToF photoelectric sensor is a laser distance sensor based on time-of-flight ranging and can address these issues.
Stable long-range detection
Measurement range reaches 0.3-5 m, covering the distance from chute to full-bag reference position.
Independent of object characteristics
ToF ranging is not affected by parcel color, material, or shape.
Environmental interference resistance
Waterproof and dustproof design resists ambient light and dust.
Visual debugging support
Optional visible red spot helps on-site alignment.
Non-contact and wear-free
Laser measurement avoids mechanical wear.

Process Overview
Smart forklifts are core logistics equipment for intelligent warehousing and smart manufacturing, widely used in handling, stacking, loading, and unloading. Their working environments are complex, with mixed traffic, narrow aisles, and dense racks, creating high requirements for safety protection and precise operation. The two key sensing needs are collision avoidance, which detects obstacles and personnel around the vehicle for active avoidance and braking, and fork-tip detection, which measures the distance from the fork tip to goods, pallets, and racks to ensure accurate and safe pickup and placement.
Scenario Pain Points
Weak Perception
Traditional solutions often use mechanical edges, ultrasonic sensors, or ordinary photoelectric sensors, which suffer from slow response, many blind spots, and poor environmental adaptability.
Difficult Fork-tip Positioning
The fork tip is a blind area for many traditional sensors, making it hard to align with pallet openings and causing collisions with goods or racks.
Slow Response
Some sensors respond too slowly for high-speed travel and cannot brake in time, creating safety hazards.
Strong Environmental Interference
Warehouse environments include dust, oil, and changing light. Traditional sensors are prone to false alarms or missed detections.
GATPOR Solution
GATPOR PS05 ToF photoelectric sensor is a laser distance sensor based on time-of-flight ranging and can address these issues.
Front collision avoidance
Install laser distance sensors at the front of the vehicle to measure the distance to obstacles or personnel in real time.
Fork-tip detection
Install compact laser sensors at the fork front or under the fork tip to measure the distance to pallet openings and goods, guiding accurate pickup and placement.
Blind-spot coverage under the fork tip
Embedded installation under the fork tip monitors low obstacles below the fork arms and prevents collisions.

All-round sensing eliminates visual blind spots. Precise fork-tip detection avoids damage to goods and racks, reducing material loss and maintenance cost. First-attempt pickup success can exceed 99.5%, reducing repeated adjustments. Based on ToF ranging, detection is not affected by target color or material, including black absorbing surfaces and reflective metal. Plug-and-play deployment supports quick retrofit with short downtime.

Process Overview
Truck loading connects warehousing and transportation and directly affects shipment efficiency and transport safety. Traditional loading relies on manual guidance and driver experience, with low efficiency, poor accuracy, and safety risks. As logistics automation improves, more loading scenarios are adopting automatic guidance and intelligent detection systems.
Scenario Pain Points
Difficult Docking Positioning
When a truck backs into the loading bay, the driver may need repeated adjustments to stop accurately. Position deviation prevents loading equipment from docking and requires manual correction.
Strong Environmental Interference
Dock areas face rain, snow, dust, and lighting changes. Traditional ultrasonic or photoelectric sensors may false alarm or fail. Inside the truck body, weak lighting limits ordinary sensor detection distance.
Low Digitalization
The loading process lacks real-time data feedback and cannot easily connect with WMS or TMS systems for visual dispatch and efficiency analysis.
GATPOR Solution
Vehicle docking guidance
