Description
SAU Retrofit Conversion for Gate Systems
Upgrade older gate operators with the SAU Retrofit Conversion from BarrierStop.com. This retrofit solution is designed to modernize aging hydraulic or mechanical gate systems by replacing outdated drive components with a dependable electro-mechanical SAU operating system.
Instead of replacing an entire gate installation, the SAU conversion allows organizations to improve performance, extend equipment life, and reduce long-term maintenance costs while utilizing much of the existing infrastructure.
Why Choose a SAU Retrofit Conversion?
Converting to an SAU electro-mechanical system offers several operational advantages:
- Reduced maintenance requirements and elimination of hydraulic fluid leaks
- Consistent performance in demanding weather conditions
- Faster and smoother gate movement
- Lower long-term service and operating costs
- Extends the service life of existing gate systems
This retrofit is an excellent option for facilities looking to improve reliability without the expense of installing an entirely new barrier system.

Complete Electro-Mechanical Upgrade
The EMR9000 conversion replaces outdated hydraulic equipment with modern electro-mechanical technology. During the retrofit, the following components are removed and upgraded:
- Original electrical control cabinet
- Hydraulic pump
- Pump motor
- Hydraulic control valves
- Fluid reservoir
- Hydraulic accumulators
- Hydraulic hoses
- Hydraulic cylinders
These components are replaced with All-Electric Sealed Actuating Units (SAUs) and a new electrical control cabinet, creating a cleaner, more efficient operating system with fewer maintenance requirements.
Optional Battery Backup
An optional battery backup system can be incorporated into the retrofit package to maintain smooth barrier operation during power interruptions. This feature helps improve system availability while supporting continuous access control when primary power is unavailable.
TIRED OF BROKEN HYDRAULIC LINES?
Upgrade your existing hydraulic barrier system with BarrierStop’s electro-mechanical retrofit solution. Hydraulic systems often require frequent maintenance due to fluid leaks, hose wear, pressure loss, and component failures. By converting to an all-electric drive system, facilities can improve reliability, reduce maintenance costs, and simplify long-term operation.
The spring-assisted Sealed Actuating Units (SAUs) utilize advanced brushless servo motor technology with integrated absolute encoders and mechanical fail-safe brakes. These components provide smooth, controlled movement during every operating cycle while securely holding the barrier in position—even when power is unavailable.
GET THE FACTS
The SAU uses a precision internal ball screw mechanism to convert the motor’s rotary motion into the linear movement required to operate the barrier. This highly efficient drive system is engineered for a service life exceeding 300,000 cycles.
Integrated spring assistance helps support the lifting load, reducing peak electrical demand while improving energy efficiency and minimizing overall system power consumption.
CONVERT VIRTUALLY ANY BARRIER
The electro-mechanical retrofit is compatible with many existing vehicle security systems, including:
- Wedge Barriers
- Bollard Barriers
- Drop Arm Barriers
- Crash Gates
Intelligent PLC Control System
Each retrofit package includes an industrial-grade PLC (Programmable Logic Controller) housed within a new electrical control cabinet. The PLC coordinates all barrier functions while communicating with existing security and access-control equipment.
The system can integrate with:
- Vehicle loop detectors
- Manual push buttons
- Traffic signal lights
- Access control systems
- Security software
- Auxiliary monitoring devices
Because the PLC software is programmable, operating parameters can be adjusted to match the specific performance requirements of each installation.
REPLACE YOUR HYDRAULICS TODAY
Moving to an all-electric barrier system offers numerous advantages:
- Eliminate hydraulic oil
- Reduce maintenance requirements
- Avoid fluid leaks and spills
- Minimize hose failures and pressure loss
- Reduce environmental cleanup concerns
- Upgrade to dependable all-electric operation
Battery Backup System
An optional battery backup system allows the barrier to continue operating during power interruptions. The backup supplies power to both the actuators and the control electronics, allowing normal barrier operation when utility power is unavailable.
The transition from AC power to DC battery operation occurs automatically without interrupting system performance. While operating on battery backup, barrier movement—particularly EFO functions—may operate at slightly reduced speeds.
The battery system is charged through a dedicated 120 VAC circuit installed within the barrier enclosure. When charging power remains available, battery capacity and operating duration are significantly extended, allowing additional operating cycles during extended power outages.
