RST-24 Trolley

The Flagship Model

RST-24 Friction Braking

Traditional magnetic brakes fade. Hand braking fails. The RST-24 uses adjustable friction pads and patented geometry to mechanically regulate deceleration, providing a consistent, smooth stop every single time.

Dual Brakes

Redundant independent braking plates ensure safety even if one side is compromised.

Slope Calibration

Easily adjust the braking force for any zipline slope using our multi-slot carabiner system.

The Weight Equalization Advantage

Why ZipSafe out-performs magnetic braking every time.

Physics, Not Magic

Our trolley adjusts friction based on force. A 35lb child and a 275lb adult will stop in the same location.

Rider Independent

The braking process is completely passive. No hand braking required, eliminating human error and panic reactions from the safety equation.

Field Serviceable

Designed by operators, for operators. Change brake pads in minutes without removing the trolley from the cable.

High Throughput

Reset in seconds, not minutes. No waiting for magnetic fields to reset or electronics to reboot.

Operator Testimonial

"The easiest maintenance we've ever had."

Operator Testimonial

"Consistent stopping power for every rider."

Troy Richardson, Founder

The "Accident-Free" Standard

"I've served as an expert witness in too many zipline injury cases. I founded ZipSafe to solve the problem at the source: The Trolley. We don't just mitigate impact; we eliminate it."

With over 20 years of field operation and patented innovations like the Barrel Spring Emergency Arrest Device, our mission is simple: Zero accidents.
