Applications
Automated / AGV Warehouse Floors
Automated vehicles are sensitive to every joint, step and slope. The floor has to be designed for the fleet: joint spacing, joint detail, flatness and long-term stability.
- AGV floor design
- AMR warehouse floor
- floor joints automated vehicles
- AGV floor flatness
Main floor risks
How should a floor be designed for AGV and AMR fleets?
- Vehicle faults and stops triggered by joint steps, spalls and uneven joint edges
- Navigation and docking errors where the floor is out of flatness tolerance
- Wear ruts along fixed guide paths that concentrate traffic on the same line
- Small cracks that become steps under repeated wheel loading
- Retrofit constraints when the fleet changes after the floor is built
Loads and operating conditions
- Small hard wheels with high contact stress on fixed paths
- High traffic frequency: the same joint crossed continuously around the clock
- Loaded vehicle mass concentrated on two or four small wheels
- Braking and acceleration at charging and transfer points
- Racking or shuttle-system loads in the storage blocks
Why conventional saw-cut floors fail here
A saw-cut grid puts joints directly across AGV paths. Every crossing is a small impact that the vehicle registers, joints wear faster under the concentrated wheel loads and any step or spall becomes a fault condition; the more joints, the more places the fleet can stop.
What a jointless design must analyse
- Fleet data: wheel type, wheel load, path layout and traffic frequency
- Flatness and levelness requirements derived from the vehicles, measured along the real paths
- Panel sizes and joint positions kept off the main paths and docking areas
- Reinforcement or post-tensioning strategy to keep the surface stable over time
- Surface hardness and wear resistance along the guide paths
Where construction joints are still required
- Construction joints at pour limits, positioned across the least critical routes
- Isolation joints at columns, racking bases and charging stations
- Joints at the interface with mezzanines, conveyors and lifts
- Movement joints where the building has expansion joints
What BICP provides
- Preliminary review of the floor against the planned fleet and layout
- Detailed analysis of slab system, flatness strategy and joint layout for the paths
- Joint and detail engineering where paths must cross joints
- Armoured joint specification inputs for those crossings, supplied through SHENTE
Questions engineers ask
- Why do AGV fleets have problems at floor joints?
- Automated vehicles run on small hard wheels along fixed paths, so every joint on the path is crossed continuously and any step, spall or open joint is felt as an impact or read as a fault. Joints also wear faster under the concentrated wheel loads.
- What floor information does an AGV supplier usually ask for?
- Flatness and levelness along the intended paths, the joint layout and joint detail, the surface hardness and the expected long-term stability of the slab. Those requirements should shape the floor design rather than be checked afterwards.
- Can joints be kept off the AGV paths entirely?
- Often most of them can. With large panels the construction joints are placed across the least critical routes and the storage blocks are designed jointless, leaving only isolation and interface joints on or near the paths.
- What happens to the floor if the fleet is changed later?
- A floor designed for one vehicle type may not meet the flatness or joint requirements of a heavier or faster fleet. Designing the slab for the likely future fleet and keeping the joint count low protects that flexibility.
