Description
The FAAC C851 Foundation Plate – 737850 is a genuine heavy-duty mounting plate designed specifically for installation of the FAAC C851 high-speed sliding gate operator.
The foundation plate provides the structural mounting interface between the C851 operator and its prepared concrete foundation, allowing the operator to be securely positioned and correctly aligned with the sliding gate rack.
Because the C851 is a powerful, high-speed industrial operator capable of moving gates weighing up to 1,800kg at adjustable speeds of up to 40m/min, a rigid and accurately positioned operator foundation is essential for reliable long-term operation.
FAAC Part Number: 737850
🏗️ Dedicated C851 Foundation Plate
The FAAC 737850 Foundation Plate is specifically designed for the:
- FAAC C851 Sliding Gate Operator
FAAC lists the 737850 as the dedicated foundation plate within the C851 accessory range.
Using the genuine mounting plate ensures the operator mounting points correspond correctly with the C851 chassis.
🔩 Secure Operator Mounting
The foundation plate forms the structural connection between the C851 operator and the prepared operator foundation.
A correctly installed plate provides a stable mounting surface capable of supporting the operator while maintaining its position during repeated gate operation.
This is particularly important for the C851 because it is designed for demanding high-speed and continuous-duty applications.
🚀 Designed for a High-Speed Operator
The FAAC C851 is capable of adjustable gate speeds between:
- 20m/min and 40m/min
At these operating speeds, correct operator mounting and rack alignment are especially important.
A rigid foundation helps minimise unwanted movement or vibration that could affect the relationship between the operator pinion and gate rack.
🏭 Heavy-Duty Industrial Application
The C851 is designed for demanding sliding gate installations and is rated for:
- Maximum Gate Weight: 1,800kg
- Maximum Gate Length: 20m
- Adjustable Gate Speed: 20–40m/min
- Maximum Expressed Force: 3,000N
- Use Frequency: 100% at 25°C
The 737850 foundation plate provides the purpose-designed mounting base for this heavy-duty operator.
⚙️ Correct Rack & Pinion Alignment
The C851 uses a:
- Z28 Pinion
- Module 4 Gear Profile
The foundation plate must be positioned so the operator pinion can be correctly aligned with the Module 4 rack installed along the sliding gate.
Correct alignment helps provide:
- Smooth gate movement
- Consistent rack engagement
- Reduced mechanical noise
- Reduced rack wear
- Reduced pinion wear
- Reduced gearbox loading
- Reliable high-speed operation
📐 Accurate Operator Positioning
The position of the foundation plate determines the final location of the C851 relative to the sliding gate.
Before the concrete foundation is completed, consideration should be given to:
- Gate position
- Gate track position
- Rack position
- Z28 drive pinion position
- Operator clearance
- Electrical conduit locations
- Manual release access
- Operator cover clearance
Careful positioning during the civil works stage can significantly simplify final operator installation.
🦷 Module 4 Rack Installation
FAAC specifies a galvanised 30 × 12mm Module 4 steel rack for typical C851 installations.
The compatible FAAC rack is:
- 30 × 12mm
- Module 4
- Galvanised steel
- Supplied with weld-on fittings
- Available in 1m sections
The foundation plate should be positioned so the C851 pinion can correctly engage with the installed rack.
⚠️ Rack Must Not Support the Gate
The sliding gate rack should not rest directly on the C851 drive pinion.
The weight of the gate must remain supported by the gate’s:
- Track
- Wheels
- Rollers
- Structural support system
Correct clearance between the rack and pinion helps prevent unnecessary loading of the C851 gearbox and output shaft.
🧱 Concrete Foundation Installation
The C851 foundation plate is intended to form part of a properly constructed operator foundation.
The foundation should provide sufficient structural stability for the forces generated by the C851 during acceleration, normal operation and deceleration.
Foundation design should consider:
- Gate weight
- Gate speed
- Soil conditions
- Operator loads
- Site drainage
- Ground stability
- Installation environment
The concrete should be fully cured before the operator is installed and commissioned.
🔌 Plan Electrical Conduits Before Pouring
Electrical conduits should be positioned before completing the operator foundation.
Depending on the installation, services entering the C851 may include:
- 230V mains power
- Photocell wiring
- Safety edge wiring
- Access-control wiring
- Intercom wiring
- Key switch wiring
- Loop detector wiring
- External control wiring
- Other low-voltage accessories
Planning the conduits during foundation preparation provides a cleaner and more serviceable installation.
⚡ Suitable for the C851 Electrical System
The C851 incorporates its E850S electronic control board and frequency inverter within the operator.
The foundation arrangement should therefore provide appropriate access for the electrical services required by the complete automation system.
Electrical conduits should be positioned so cables can enter the operator correctly without interfering with the mounting plate or operator chassis.
🛠️ New C851 Installations
The FAAC 737850 Foundation Plate is primarily intended for new C851 installations.
The plate can be positioned during the civil works stage before the operator itself is installed.
Once the foundation has cured, the C851 can be mounted to the prepared plate and aligned with the gate rack.
🔄 Replacement Installations
The foundation plate may also be required when replacing or relocating an existing C851 operator.
Before reusing an existing foundation, inspect:
- Foundation condition
- Plate condition
- Operator mounting points
- Corrosion
- Concrete condition
- Rack alignment
- Pinion position
- Electrical conduit location
A damaged, loose or incorrectly positioned foundation should be corrected before installing the operator.

🔗 Compatibility
Designed specifically for:
- FAAC C851 Sliding Gate Operator – Part 109903
The C851 uses a Z28 Module 4 pinion and FAAC specifies the 737850 as the dedicated C851 foundation plate.
This foundation plate should not be assumed to fit other FAAC sliding gate operator families.
Always confirm the operator model before ordering.
⚠️ Please Note
This product is the genuine FAAC C851 Foundation Plate.
FAAC Part Number: 737850
The FAAC C851 sliding gate operator is not included.
The gate rack, concrete foundation and electrical installation are not included.
The foundation plate must be accurately positioned to maintain correct alignment between the C851 Z28 drive pinion and the Module 4 gate rack.
The sliding gate rack must not transfer the weight of the gate onto the operator pinion. The gate itself must remain correctly supported by its track, wheels and structural hardware.
Because the C851 is capable of high-speed operation up to 40m/min and continuous-duty use, the operator foundation must be appropriately designed and constructed for the installation.
Electrical conduits and other underground services should be planned before the concrete foundation is completed.
