Entering a modern intelligent warehousing center, what catches the eye is AGV cars flowing in the alleys like blood, multi-level shuttle cars lifting and lowering precisely in the three-dimensional warehouse, and automatic guided vehicles shuttling in an orderly manner along an invisible path. Behind the silent operation of these smart devices, there is an underestimated but crucial technical detail – the vast majority of them are equipped with high-performance polyurethane wheels. This is not only a material selection, but also the fundamental engineering for achieving efficient, precise, and reliable operation of intelligent logistics systems.

Polyurethane wheel: the “flexible joint” of intelligent devices

In traditional warehousing, the main task of forklift wheels is to carry and move. In the intelligent warehousing system, polyurethane wheels play a more complex role:

1. Precise locator for AGV car

The excellent elastic modulus of the polyurethane wheels of the AGV car can absorb small unevenness on the ground (≤ 2mm), ensuring that the AGV positioning accuracy is always maintained within ± 5mm. Moreover, the dark polyurethane surface will not interfere with the ranging accuracy of the laser navigation system. For example, after all 200 AGVs in a certain e-commerce distribution center were equipped with YALIDE customized polyurethane wheels, the navigation correction frequency decreased by 73%.

2. The “vibration filter” of the multi-layer shuttle car

When the shuttle car runs at high speed (≥ 4m/s), the polyurethane with special formula can effectively absorb the starting/braking impact; It can protect the precision shelf structure and reduce the risk of bolt loosening caused by long-term vibration. Actual test data shows that the use of high-performance shock-absorbing polyurethane wheels extends the shelf maintenance cycle by 2.3 times.

3. Energy saving device for automatic guided vehicles

The low rolling resistance formula of polyurethane wheels in automatic guided vehicles can reduce the load on the drive motor by 10-15%. In unmanned warehouses that operate continuously for 24 hours, this alone can save tens of thousands of yuan in electricity costs annually.

Customized solutions for special scenarios

1. The “anti brittleness warrior” of cold chain unmanned warehouses

In cold chain unmanned warehouses, low-temperature resistant modified polyurethane wheels are used (maintaining elastic temperature range: -40 ℃ to+60 ℃). The surface of these wheels is designed with an anti icing formula to prevent the wheel rim from freezing and causing slippage. After many fresh logistics companies use low-temperature resistant polyurethane wheels, the equipment failure rate in -25 ℃ environment has decreased by 67%.

2. The “dust-free guardian” of clean storage

In many semiconductor manufacturing workshops and LCD panel manufacturing workshops, strict measures are taken to prevent dust and static electricity. The equipment in these workshops uses polyurethane wheels with a silicon free and dust-free formula, which meets the cleanliness requirements of ISO Class 5 or above, and adopts a special structural design to prevent debris accumulation. These effects have also been validated in many smart warehouses in the pharmaceutical and electronics industries.

3. The ‘load-bearing expert’ of heavy-duty material box robots

In coastal ports or some mineral areas, the weight of goods that usually need to be transported exceeds 500kg. So the polyurethane wheels used in these places are high-density polyurethane wheels optimized for dynamic loads, with internal reinforcement structure design to avoid deformation under heavy loads. Generally, the tested load-bearing capacity of this type of polyurethane wheel is about 40% higher than that of standard wheels.

YALIDE’s Intelligent Warehousing Special Technology

Based on a deep understanding of intelligent logistics equipment, we have developed a specialized technical system:

1. Ground equipment wheel system matching algorithm

Through 3D modeling analysis: elastic deformation of epoxy flooring with different thicknesses; The influence of equipment acceleration on the shear force on the ground; Optimal hardness matching curve (usually recommended in the 85A-92A range)

2. Dynamic performance verification platform

Durability testing platform that simulates actual operating trajectories (with accumulated testing mileage exceeding 100000 kilometers); Simulation of high-speed emergency stop and start conditions (6 cycles per minute, continuous testing for 72 hours); Ground compatibility acceleration test (quantitative evaluation of indicators such as wheel trace residue and color transfer).

3. Intelligent predictive maintenance system

Establish a digital history for each wheel: real-time wear monitoring model, remaining life prediction algorithm, and best replacement time reminder service.

Five key dimensions for selecting intelligent warehousing wheels.

Accuracy dimension: whether it meets the requirements of the navigation system for ground feedback;

Durability dimension: theoretical service life under predetermined operating conditions;

Economic dimension: Total cost of ownership (procurement+replacement+downtime losses);

Safety dimension: special certifications such as flame retardant and anti-static;

Compatibility dimension: adaptability to existing device control systems.

YALIDE’s commitment:

We understand that in intelligent warehousing, each wheel is no longer an isolated component, but a “data touchpoint” of the entire digital logistics system. We not only provide products that meet specifications, but also solutions that have been systematically validated and can improve overall operational reliability.

When planning or upgrading an intelligent warehousing system, remember that excellent hardware design determines the lower limit of system capabilities, while seemingly small key components like polyurethane wheels often determine the upper limit of system efficiency.

The YALIDE intelligent logistics dedicated wheel series provides a solid physical foundation for your digital transformation.
