Industrial-Strength 4,000 lb Gate Capacity

The MAX RHINO 4000 FS is designed for large, heavy sliding gates that exceed the capacity of many standard commercial gate operators.

With a maximum rated gate weight of 4,000 lbs and a published maximum gate length of 50 feet, the RHINO provides the mechanical strength required for demanding industrial vehicle entrances.

Its high-torque brushless motor and heavy-duty direct-drive gearbox provide consistent gate movement while minimizing the mechanical components commonly associated with conventional belt-driven operators.

The MAX RHINO 4000 FS is particularly well suited for industrial properties where large gates must operate frequently without sacrificing reliability or security.

Important: The published 4,000 lb capacity applies to properly constructed, level, freely rolling sliding gates. The operator is not intended for uphill or downhill gate applications. Gate condition, rolling resistance, and installation geometry must be evaluated before selecting an operator.

High-Torque Brushless DC Motor & Size 70 Gearbox

The MAX RHINO 4000 FS incorporates a powerful 24V brushless DC motor with performance equivalent to a 2-1/2 HP AC motor.

Brushless motor technology eliminates conventional motor brushes, reducing mechanical wear and supporting efficient, continuous-duty operation.

The motor uses position feedback and intelligent electronic control to provide smooth acceleration, controlled deceleration, and accurate gate movement.

Maximum Controls publishes a motor design life of up to 6 million cycles under specified operating conditions.

The motor is paired with a Size 70 industrial cast iron gearbox featuring a 17:1 reduction ratio, designed for heavy-duty power transmission.

The direct-drive gearbox operates in an oil bath and eliminates internal belts and pulleys, helping reduce routine mechanical maintenance requirements.

This combination provides the power and durability needed for demanding industrial sliding gate applications.

Fail-Safe Operation & Emergency Manual Gate Release

One of the MAX RHINO 4000 FS's most important features is its fail-safe, back-drivable design.

During normal operation, the operator's dynamic braking system helps secure the gate against unauthorized movement.

When the braking system is released through an authorized command, the gate can be manually pushed open or closed without requiring normal powered operation.

Supported release methods include:

• Local manual release switch

• Compatible external keypad

• Key switch or dry-contact relay

• Compatible remote release controls, where supported and configured

This capability is particularly valuable for industrial properties requiring emergency vehicle access, maintenance access, and contingency procedures during electrical outages.

The fail-safe system works alongside the operator's integrated battery backup to provide additional options for managing gate accessibility.

Important: Fail-safe release does not mean the gate automatically opens during every power interruption. Actual behavior depends on the operator's programming, release configuration, remaining battery power, and installed access control equipment.

Adjustable Gate Speed & Intelligent Motion Control

The MAX RHINO 4000 FS features independently adjustable opening and closing speeds to accommodate the requirements of industrial gate installations.

The manufacturer's current catalog specifies a standard gate speed of 12 inches per second, while additional manufacturer documentation describes selectable high-speed operation reaching approximately 18–19 inches per second under qualifying conditions.

Programmable acceleration and deceleration help maintain smooth gate movement and reduce mechanical shock.

The Matrix III controller also provides intelligent motor regulation, obstruction detection, and controlled stopping performance.

High-speed operation should only be configured within the manufacturer's approved gate weight, safety, and installation limits.

Matrix III Intelligent Control System

The MAX RHINO 4000 FS incorporates Maximum Controls' advanced Matrix III control system, providing extensive programming and diagnostic capabilities for industrial gate installations.

The controller uses adaptive Digital Signal Processing technology to regulate brushless motor performance and monitor operating conditions.

Key functions include:

• Programmable gate opening and closing speeds

• Adjustable acceleration and deceleration

• Automatic closing timer

• Programmable partial gate opening

• Adaptive electronic reversing detection

• Primary and secondary operator coordination

• Anti-tailgating security functions

• Gate disable and tamper monitoring

• Gate position and status outputs

• Magnetic lock control

• Integrated LCD diagnostic display

• Event history logging for up to 8,000 events

These capabilities allow installers to configure the operator for demanding industrial security applications while providing valuable diagnostic information for ongoing maintenance and troubleshooting.

Integrated Battery Backup & Power Management

The MAX RHINO 4000 FS includes an integrated battery backup system utilizing two 12V, 7Ah AGM batteries.

Maximum Controls publishes approximately 40 backup cycles under specified conditions, although actual operating cycles depend on gate weight, gate length, battery condition, temperature, and mechanical resistance.

When normal AC power is available, the operator does not rely on battery power for routine gate movement.

Additional electrical capabilities include:

• Switchable 115V / 230V AC single-phase input

• Built-in 12V DC and 24V DC accessory power outputs

• Compatible 24V DC solar input

• Intelligent energy-saving power management

• Motor overcurrent safety protection

• Advanced lightning and surge protection

• Programmable power-loss operation

These features support industrial installations requiring dependable power management and emergency operation.

Industrial Security & Anti-Tamper Protection

The MAX RHINO 4000 FS incorporates advanced security functions designed for restricted-access industrial entrances.

Dynamic Magnetic Braking: Helps resist unauthorized attempts to push the gate open while the operator is secured.

Tamper Detection: Audible alarms and relay outputs can provide notification of attempted unauthorized gate movement.

Anti-Tailgating Functionality: Programmable vehicle access controls help manage unauthorized entry behind approved vehicles.

Gate Status Monitoring: Dedicated outputs provide gate position information for compatible security and monitoring systems.

Optional Chain-Drop Detection: Compatible chain monitoring equipment can detect chain disengagement and trigger configured alarms.

Lockable Steel Cover: Helps restrict unauthorized access to the operator's internal controls and mechanical components.

Programmable Partial Opening: Allows authorized access configurations without requiring the gate to travel its full distance for every operation.

These features make the RHINO 4000 FS suitable for industrial properties requiring both reliable vehicle access and enhanced perimeter security.

UL 325 Class III & IV Safety Requirements

The MAX RHINO 4000 FS is intended for UL 325 Class III and Class IV vehicular sliding gate applications only.

Class III applications generally include industrial locations such as factories, warehouses, and loading facilities where access is restricted from the general public.

Class IV applications include guarded or restricted-access facilities where entry is controlled by security personnel.

The operator incorporates inherent electronic reversing detection and supports monitored external entrapment protection devices.

Two monitored entrapment protection sensors are required, with one protecting each direction of gate travel, according to the manufacturer's installation manual.

Compatible devices include appropriately configured monitored photoelectric sensors and sensing edges.

The MAX RHINO 4000 FS is not intended for Class I residential or Class II general-access commercial installations.
