What are the advantages of Electromechanical bollards compared with Hydraulic bollards?

In modern security systems, automatic bollards have become a key facility. At present, the mainstream products on the market are divided into “electromechanical drive type” and “hydraulic drive type”, and UPARK electromechanical bollards are gradually replacing the traditional hydraulic products by virtue of their technical advantages. This article will be from the “anti-collision ability, blackout protection, environmental protection, maintenance costs, intelligent control and environmental adaptability” six dimensions, a detailed comparison of the differences between the two, to help you make a more scientific choice.

1.Anti-collision ability and blackout protection: electromechanical bollard safety is better
When comparing the anti-collision capabilities of electromechanical bollards and hydraulic bollards, we use the same specifications for a fair assessment: a diameter of 219mm, an above-ground height of 600mm, and a thickness of 6mm. The overlap area between the outer cylinder and the bollard body plays a crucial role in determining anti-collision performance. UPARK electromechanical bollards typically feature a larger overlap area, which is why—for the same above-ground height—their outer cylinder is taller than that of automatic bollards.
In the event of a power failure or malfunction, hydraulic bollards lose functionality because the pump shuts down, causing the bollard body to descend automatically (some models require manual pressure release). As a result, they essentially lose their anti-collision capability. In contrast, UPARK electromechanical bollards utilize a mechanical screw structure that locks automatically during a power outage, preventing any unintended lowering and ensuring continuous protection.
2.Environmentally friendly and quiet: Electromechanical bollards achieve more environmentally friendly operation.
Hydraulic bollards may leak hydraulic oil after long-term use (especially when the seals deteriorate), contaminating the soil and groundwater. UPARK electromechanical bollards do not require hydraulic oil in the driving process, eliminating the risk of oil contamination, and the overall operating noise of hydraulic bollards is louder than that of UPARK automatic bollards.
3. Maintenance costs: modular design, simple structure, low maintenance costs
Hydraulic bollards require regular replacement of hydraulic oil (usually every 1-2 years), and the oil seals are easy to aging, leakage of oil requires professional equipment overhaul. Due to the complex structure of the hydraulic system, the weight of various accessories is heavier, in the maintenance of a single hydraulic bollard, at least two people need to operate together.
Electromechanical bollard for the fully enclosed design, modular design, light weight accessories, single maintenance, only one person can complete, maintenance time cost and labor cost is lower.
4. Intelligent control and safety protection:electromechanical bollards are leading the way
Limit Sensor: Electromechanical bollard built-in limit sensor, the column rises / falls to the limit position automatically stop, to avoid motor blocking burned. Hydraulic bollards without limit sensors, column rise or fall in accordance with the time set in advance to determine its stroke, so there will be, in hot weather, the hydraulic oil will become thin, the same time will push the bollard to rise longer stroke, so there will be a blockage of the situation, in the case of low temperatures, if the hydraulic oil becomes viscous, the same amount of time, push the rod stroke is shorter, so there will be a case of high and low.
Anti-topping function: electromechanical bollard in the process of rising if the top of the column touches the vehicle chassis, the bollard will detect the pressure, at this time, the bollard will stop rising, to avoid vehicle damage, while the hydraulic bollard does not have this function, easy to cause damage to the vehicle.
5. Environmental adaptability: electromechanical bollards are resistant to extreme temperatures

Hydraulic model of the bollard oil pressure is greatly affected by temperature, the temperature is too low will thicken, need to add additional heating equipment to solve the problem, increasing the difficulty of equipment maintenance. While UPARK electromechanical bollard mechanical screw actuator, in the -25 ℃ ~ 70 ℃ environment can still work normally, without additional temperature control equipment.

Through comparison, UPARK electro-mechanical bollards crush hydraulic products in terms of “safety, reliability, intelligence and total cost of ownership”. In the choice of automatic bollards, to fully consider the application of the bollards, the performance of the bollards themselves, but also to consider its after-sales maintenance costs, of course, environmental protection is also a very important point.
