Many warehouses today are no longer limited to a single floor. Multi-level storage facilities, production buildings and distribution centers increasingly require automated material transportation between different floors.

When companies import AGV forklifts from China, one of the most important questions is whether the automation system can safely operate across multiple floors and communicate with existing building infrastructure.

Why Multi-Floor AGV Automation Is More Complex Than Single-Floor Systems

A traditional forklift operator can manually enter an elevator, select a floor and continue transportation. An autonomous forklift must complete the same process automatically while maintaining safety.

A multi-floor AGV system needs to coordinate:

• AGV navigation system

• Fleet management software

• Freight elevator control system

• Automatic doors

• Warehouse management system

Can Chinese AGVs Automatically Call and Use Freight Elevators?

Advanced AGV systems can integrate with freight elevators through communication interfaces and control signals.

A typical automated elevator transportation process includes:

• AGV receives a transportation task

• AGV travels to elevator waiting area

• AGV sends elevator request signal

• Elevator arrives at assigned floor

• Door status is confirmed

• AGV enters elevator safely

• AGV exits at destination floor

How Do Chinese AGVs Communicate With Local Elevator PLC Systems?

The communication method depends on the existing elevator control architecture and project requirements.

Before deployment, customers should confirm elevator interface documents and define communication responsibilities between AGV suppliers and elevator manufacturers.

What Safety Measures Prevent AGVs From Entering an Unsafe Elevator Area?

Safety is the most important consideration when autonomous vehicles interact with elevators.

A professional system should include:

• Elevator position confirmation

• Door open and closed status detection

• Vehicle permission signal verification

• Restricted movement zones

• Emergency stop integration

The AGV should only enter the elevator when all required safety conditions are confirmed.

How Does AGV Navigation Handle Different Floors?

Multi-floor warehouses require advanced map management because every floor represents a different navigation environment.

The fleet software must manage:

• Individual floor maps

• Floor transition points

• Elevator entry and exit locations

• Coordinate transformation between floors

• Vehicle position recovery after elevator movement

What Information Should Be Prepared Before a Multi-Floor AGV Project?

Questions to Ask Chinese AGV Suppliers

• Can the AGV integrate with freight elevators?

• What communication protocols are supported?

• How is elevator safety verified?

• Can the system manage multiple floor maps?

• How does the AGV recover position after elevator movement?

• Can the supplier provide previous multi-floor project experience?

Industry Perspective

From our experience with warehouse automation projects, multi-floor AGV deployment is not mainly a robot navigation challenge. The real difficulty is coordinating multiple systems into one reliable workflow.

A successful project requires cooperation between AGV suppliers, elevator manufacturers, facility engineers and IT teams.

In our opinion, future warehouse automation will increasingly move toward complex environments including multi-floor buildings, high-density storage and mixed automation systems.

For companies importing AGVs from China, selecting a supplier with strong integration capability is often more important than choosing the lowest equipment price.
