Evo-Tech Rigid Chain Technology: A Vertical Space Revolution for Multi-Level Parking Garages
How can we break through the three major bottlenecks of traditional parking garages—“lifting jolts, frequent maintenance needs, and low space utilization”?

Home page

Multi-story parking garage

As urbanization accelerates, city population density continues to rise, and the number of vehicles owned keeps growing steadily—leading to the widespread challenge of "parking difficulties," which now severely hampers urban development and diminishes residents' quality of life. In densely populated urban centers, older residential neighborhoods, commercial complexes, hospitals, schools, and other high-demand areas, the gap between parking supply and demand has become particularly acute. Traditional flat-level parking methods, with their large land footprint and low space efficiency, can no longer meet the modern city’s need for maximizing land use. This is where multi-story parking garages emerge as a practical solution, offering a way to make the most of vertical space and dramatically boosting land utilization. By stacking vehicles vertically across multiple levels, these innovative structures can accommodate significantly more parking spaces than conventional flat parking lots—making them a vital tool for easing parking pressures in urban areas.

Background Challenge

Although automated parking garages offer significant advantages, they still face numerous technical and practical challenges during both construction and operation:

Balancing space efficiency with design flexibility: Different scenarios impose specific requirements on the dimensions and layout of automated parking systems, while complex or compact sites pose even greater challenges in terms of equipment compactness and adaptability. Traditional lifting and transmission methods may struggle to achieve optimal layouts in certain extreme spatial constraints.
Requirements for Smooth Operation and Safety: The lifting and lateral movement of vehicles must be executed with exceptional smoothness and safety to ensure the protection of both vehicles and personnel. This places a rigorous demand on the precision, rigidity, and braking reliability of the transmission system.
The conflict between load-bearing capacity and structural lightweighting: With the growing popularity of large vehicles like SUVs, multi-level parking garages now demand higher load-bearing capacities for individual parking spaces. Balancing the need for sufficient strength with the goal of lightening the equipment’s structure—while simultaneously reducing the requirements for robust civil-engineering foundations—presents a significant challenge in the design process.
Maintenance Costs and Service Life: Automated parking systems are classified as specialized equipment, and their maintenance costs and service life directly impact the project's economic viability and sustainability. Traditional transmission components, such as steel cables and chains, are prone to wear and tear and stretching, requiring regular maintenance and replacement—tasks that significantly increase operational expenses.
Environmental adaptability and low-noise requirements: Whether in residential or commercial areas, the operational noise of automated parking systems must be strictly controlled. Additionally, certain outdoor or semi-outdoor settings require consideration of the equipment’s ability to withstand temperature, humidity, and corrosive environments.

Value and Benefits

Improving space utilization and increasing parking capacity: Evo-Tech's rigid-chain compact design enables a more efficient garage layout within limited spaces, directly boosting the project's economic or social benefits by expanding parking availability.
Reducing civil engineering costs: The rigid chain drive system is relatively lightweight and places more balanced loads on the installation foundation, which can help lower the structural strength requirements for civil engineering works to some extent, ultimately saving initial construction expenses.
Reducing operational and maintenance costs: The rigid chain's long lifespan and low-maintenance features significantly lower parking garage maintenance expenses, replacement part costs, and downtime losses caused by upkeep over the facility's entire lifecycle.
Enhancing equipment reliability to safeguard operational revenue: High reliability translates into lower failure rates and increased equipment availability, ensuring the continuous operation of the parking facility and protecting owners' revenue from parking fees.

Evo-Tech Rigid Chain Technology Solution

01.

Outstanding rigidity and load-bearing capacity

In the extended state, the Evo-Tech rigid chain exhibits exceptionally high stiffness, providing robust axial load-bearing capacity and resistance to eccentric loading, thereby ensuring stable vehicle lifting and lowering while meeting heavy-load requirements.

02.

Compact structure with design flexibility

The rigid chain system features a compact structure and requires minimal installation space, enabling efficient use of vertical space in particular. Its modular design allows for flexible configuration across parking garages of varying sizes and layouts.

03.

Smooth operation, precise positioning

Due to its rigid transmission characteristics, compared to flexible drives like steel cables, rigid chains exhibit virtually no elastic deformation during lifting and lowering, resulting in smoother operation, reduced vibration and noise, and enhanced positioning accuracy.

04.

Safe and reliable, easy to maintain

Rigid chains offer a precise transmission ratio with no slippage. Some designs include fail-safe features, ensuring reliable braking even in the event of a power failure. Their robust and durable construction results in minimal wear, leading to extended maintenance intervals—and significantly lower maintenance costs compared to traditional wire ropes or standard chains.

05.

Long lifespan and strong environmental adaptability

High-quality material selection and precision manufacturing processes ensure the long service life of Evo-Tech rigid chains. Their enclosed or semi-enclosed design helps prevent dust and dirt buildup, making them suitable for a wide range of environmental conditions.
