The Radius Dual Crank 1500 GPM Extendable Monitor is a high‑performance, deck‑mounted firefighting monitor engineered to deliver exceptional reach, elevated nozzle height, and powerful water flow. Designed for both new and retrofit fire apparatus, it provides precise directional control, high flow capacity, and reliable operation in demanding fireground environments.

Features

• High-Flow Capacity: Delivers up to 1500 GPM 6000 LPM for high-demand firefighting
• Full Flow in Any Position: Maintains full capability whether deployed or stowed
• Automatic Drain Valve: Built-in drainage for efficient operation and freeze protection
• Pressure Gauge Port: Threaded port provided for optional pressure monitoring

Range & Reach Features

• Elevated Nozzle Outlet: Extends up to 22.9 in above the inlet flange for improved stream reach
• 360° Rotation: Continuous horizontal travel for precise targeting
• Vertical Travel: 90° above horizontal and 45° below for broad operational coverage
• Compact Swing Radius: 14.8 in for reduced apparatus clearance needs

Control & Operation Features

• Dual Crank Control: Separate stainless-steel worm gear cranks for horizontal and vertical movement
• Quick Deployment: Simple pull-and-lift articulation with spring-loaded locking pin
• Raised Position Indicator: Includes 12 VDC stow/raised sensor system for enhanced safety
• Rigid Inlet & Outlet: Stable, reliable connection for consistent performance

Durability & Construction Features

• Hardcoat Anodized Aluminum: Internal and external silver powder coat finish for long-lasting protection
• Grease Fittings at All Pivot Points: Ensures smooth operation and simplified maintenance
• Heavy-Duty Build: Designed to withstand harsh firefighting conditions

How Is It Used

This monitor is mounted to the deck of a fire apparatus and operated using dual crank handles to control horizontal rotation and vertical elevation. The outlet section can be raised manually to increase nozzle height, then locked into position for flowing. When needed, operators quickly deploy the monitor using the pull-and-lift mechanism, direct the stream precisely, and supply water from a compatible 3" apparatus connection.

Who Uses It

Fire departments, industrial emergency response teams, and apparatus manufacturers rely on this monitor for high-volume water delivery, long-range stream performance, and reliable deck-mounted fire suppression.

Maintenance Information

Routine lubrication is simplified with grease fittings located at all pivot points. Periodic inspection of the worm gear cranks, articulation pin, and stow sensor system ensures continued reliability. The automatic drain valve assists with water removal after operation, helping prevent freezing and corrosion.

Storage Information

The monitor is designed to stow securely in a locked-down position using the integrated mechanism and stow sensor. It should remain in the lowered position during transport or when not in use to protect components and maintain apparatus clearance.
