Evo-Tech Rigid Chain Technology: Revolutionizing Precision and Load Capacity in Heavy-Duty Lifting AGVs

Home page

Overloaded AGV

As industrial automation accelerates its penetration into the heavy manufacturing sector, heavy-duty AGVs and RGVs have become core equipment driving intelligent transformation across many industries. In heavy-load scenarios, achieving precise positioning and ensuring stable operation remain critical challenges—key to both technological breakthroughs and innovative applications of AGVs in material handling. So, how can heavy-duty lifting AGVs overcome the "impossible triangle" of "high precision + large payload capacity + low maintenance"?

Industrial Solutions

Industrial scenarios

In certain heavily loaded AGV/RGV application scenarios, lifting, pushing/pulling, and collaboration are the three core operational steps:

Lifting and Lowering: By adjusting the load height, this system meets the material-handling needs for various scenarios—such as transporting large components from the ground to assembly line workstations, or lifting items from low-level storage areas to high-positioned processing equipment. It’s especially well-suited for multi-tiered racking systems, high-and-low workstation setups, and operations in specialized environments.
Push-pull: In heavy machinery production, a high-capacity AGV pushes fully processed large components—such as machine tool beds—from the machining station to the assembly station, or pulls raw materials from the storage area directly into the production line.
The synergy of lifting and sliding functions: In complex tasks, lifting and sliding functionalities are often used together to achieve an integrated operation of "height adjustment + lateral movement," further enhancing automation levels.

Background Challenge

Currently, the AGV field faces three major technological bottlenecks:

Issue of declining positioning accuracy: In traditional transmission-based lifting platforms, under a 10–15-ton load, positioning accuracy degrades after every 1,000 cycles, requiring frequent recalibration.
Oil leakage issue: Seals need to be replaced every 3 months, disrupting production flow.
High maintenance costs: Monthly downtime for repairs due to wear and tear on structural components is impacting production efficiency.

Evo-Tech Rigid Chain Technology Solution

01.

Enhanced load-bearing capacity

The single-chain dynamic load-bearing system supports 3 tons or more, converting the rotary motion of the servo motor into linear lifting motion while maintaining zero deformation even under heavy loads.

02.

Precision positioning

Rigid chain technology leverages the stable structure of rigid chains and a closed-loop control system driven by servo motors, achieving positioning accuracy as high as ±0.1 mm.

03.

Zero-oil-leakage design

The rigid-chain technology features fully electric drive, eliminating the need for hydraulic systems and completely removing the risk of oil leaks. This not only prevents environmental pollution—such as the costs associated with oil spill cleanup—and minimizes safety hazards but also reduces maintenance frequency.

04.

Outstanding Reliability

The modular design of the rigid chain and its highly wear-resistant materials significantly extend equipment lifespan, while keeping the failure rate below 1/5 of that seen in conventional transmissions. Additionally, preventive maintenance helps minimize unplanned downtime.
