I. The widespread adoption of mechanical parking garages and the necessity of dedicated braking systems have become the core of security measures.
The number of motor vehicles in cities continues to increase, and the shortage of parking spaces in residential communities, commercial complexes, and industrial zones is constantly expanding. The lifting and lateral moving, vertical lifting, and simple lifting types of parking garages with small land occupation and high floor area ratios have become the mainstream equipment for urban parking capacity expansion. These parking garages complete the lifting and lateral movement of the vehicle platform through motor drive and chain or steel wire rope traction, bearing the weight of the entire vehicle, with high traffic volume and frequent start-stop operations. They belong to special equipment for parking facilities and the safety and stability of equipment operation are the key points for operation management and control.
The brake, as the core safety component of the parking garage's drive motor and lifting transmission system, is responsible for starting and stopping, lifting and parking, power-off locking, and emergency braking. It is a key component to avoid the risk of the vehicle platform sliding, falling, or misalignment. Ordinary industrial brakes are not suitable for this environment and are prone to slipping, coil aging, and brake failure under conditions such as dampness, dust, and temperature differences between day and night. This increases the maintenance pressure and parking safety risks of the equipment. Parking garages with dedicated braking systems for the garage are developed based on customized designs for the specific working conditions of the garage, including emergency braking, waterproof and dustproof functions, low noise and stability, and low wear during start-stop operations. They are suitable for all types of mechanical parking equipment and take into account the efficiency of vehicle access, parking safety, and long-term operation maintenance. They are also suitable for retrofitting existing garages and providing complete equipment for new garages.
II. Specialized use pain points of braking components in parking garages
Unlike ordinary industrial transmission equipment, the braking usage scenarios of parking garages have specific characteristics, with specific requirements for the protection level of the brake, braking logic, and torque stability. The adaptability of general braking components is relatively poor. Facing conditions such as dampness, dust, and temperature differences between day and night in the garage, ordinary sealed brakes are prone to slipping, coil aging, and brake failure, increasing the maintenance pressure and parking safety risks. Parking garages are often located in underground garages or around open buildings. Underground spaces have high humidity and frequent water splashes, while open garages are exposed to direct sunlight and rain. Ordinary sealed brakes are prone to water and dust ingress, causing rust and jamming on the friction disc surface, affecting the accuracy of brake engagement.
The uneven load during equipment start-stop, large fluctuations in vehicle weight during parking and retrieval, frequent switching between empty and full loads, require the brake to dynamically adapt to the load torque. Inconsistent torque can easily cause the vehicle platform to slightly slide, damaging the garage tracks and chain structure. At the same time, the daily parking and retrieval frequency of parking garages is high, and the frequency of braking clutch operations is dense. The friction pads of conventional brakes wear out quickly due to frequent disassembly and replacement, occupying the usage time of the garage and increasing the annual inspection and maintenance costs of special equipment. Moreover, parking garages are classified as public safety special equipment. In the event of power failure, they must be self-locked for parking to prevent the vehicle platform from falling. There are strict standards for the response speed of emergency braking. Ordinary brakes with power-off braking lag and cannot meet the safety standards of parking garages.
III. Specialized performance advantages of parking garage series brakes
Parking garage series brakes adopt a normally closed power-off braking architecture, which is in line with safety regulations for special equipment. When powered on, they release the brake and allow the equipment to operate normally for lifting and lateral movement; when power is cut off or there is a fault power outage, they automatically apply the brake to lock the transmission shaft and quickly fix the position of the vehicle platform, avoiding the risks of weight loss and sliding. They are suitable for emergency safety protection standards of the garage. The product is divided into two major styles: AC and DC. They are connected to the original electrical control circuit of the garage and do not require additional electrical transformation components. They are suitable for both new and old garage motor drive systems. The entire machine strengthens the dedicated protective structure of the garage, using a multi-layer sealed waterproof and dustproof architecture to enhance the cavity's sealing performance. It resists moisture from underground, dust from the road surface, and water splashes from car washing, adapting to long-term use in damp underground and variable open environments. Special modified friction braking materials are suitable for alternating heavy and light loads. Full-load braking does not slip, and empty-load start-stop engagement is smooth. The braking has no impact or vibration, reducing the shaking and offset of the vehicle platform, protecting the garage chains, tracks, and transmission shaft linkage structure, and reducing the wear of transmission components. Optimize the low-frequency start-stop adaptation structure to match the slow and intermittent operation rhythm of the garage, with controllable coil temperature rise. This design reduces the risk of overheating and aging of the coil when the vehicle is parked for a long time, thereby lowering the probability of coil burnout and insulation damage. Improve the noise reduction process of the clutch to weaken the braking impact noise, and adapt to the night-time parking operations in residential areas. This reduces noise disturbance and is suitable for all-day parking scenarios in residential areas and commercial districts. The overall torque adjustment is adapted to the industry standards of the garage, with balanced and controllable braking torque, meeting the annual inspection requirements for special equipment, and suitable for the compliant installation of various mechanical parking equipment.
Four. Classified and adapted models, suitable for all types of vertical garage accessories
Vertical and horizontal movement vertical garage: As a commonly used model in residential areas, the equipment performs layer-by-layer horizontal movement and layer-by-layer vertical movement, with high start-stop frequency. It is suitable for small and medium-sized electromagnetic brakes, has a small size, is easy to install, and is suitable for installation at the rear end of the motor, occupying less transmission space. It is suitable for synchronous control of multiple layers of parking spaces, and maintenance and disassembly are convenient.
Vertical lift vertical garage: Large tower-type parking equipment with large load-bearing capacity and high lifting height, suitable for special disc-type brakes with large torque, sufficient parking locking force, stable positioning at high altitudes, strong resistance to wind disturbance and load offset, ensuring stable parking of the load-bearing plate at high altitudes.
Simple vertical lift vertical garage: Small-scale double-layer parking equipment in factory areas, suitable for lightweight and compact brakes, simple wiring, low operation and maintenance threshold, suitable for low-cost garage retrofitting, and suitable for installation in parks and units for self-use parking equipment.
Five. Standardize operation and control, reduce the later operation and maintenance costs of garages
The brake wear of the series of brakes is controllable, suitable for the annual unified maintenance rhythm of special equipment in garages, reducing the frequency of scattered disassembly and maintenance. Daily operation only requires regular checks on the wear condition of the friction plates, the waterproof sealing performance of the connection ports, and the cleaning of external dust and water stains. In damp garages, regular checks for the integrity of the seals are conducted to prevent water vapor from eroding internal components; for frequent use of garages, regular maintenance of the linkage structure is carried out as needed to extend the service life of the components.
Currently, this series of brakes is standardized for mass production, with unified installation dimensions and electrical control parameters, and has strong versatility. Old garages can be directly replaced and installed without modifying the transmission base and control lines, shortening the downtime for equipment renovation. In line with the current trend of safety and low maintenance upgrades in vertical garages, relying on high adaptability, high safety, and easy operation and maintenance characteristics, it ensures the smooth operation of mechanical parking equipment and helps the safe and long-term operation of urban parking facilities.
