LightSpeed Impact Trolley

This versatile zip line trolley will help create the best rider experience and increase throughput.

Impact Zip Line Trolley Benefits

The LightSpeed Impact Zip Line Trolley was designed specifically for zip lines and is engineered with impact braking in mind. It’s the most versatile trolley because it can be used on small and large diameter lines, and it comes with multiple accessory options to create the best rider experience and higher throughput.

Forward Design

Our forward design controls the rider’s forward momentum for smooth braking and a better rider experience. Most trolleys drag their back end on the cable during braking, but our forward design prevents this to prevent excess wear on your line.

Designed for Impact Braking

The Impact Trolley is designed for impact braking with a durable front impact surface and a forward design. These features extend the life of the trolley while also reducing wear on your zip line gear.


This versatile trolley works on large or small diameter lines. The optional t-handle accessory improves rider comfort and helps them to stay facing forward, and a hook accessory enables easy rider retrieval.

Made to Last

Built with anodized aluminum to withstand impact braking and maximize your ROI.

Fastest Compact Trolley

Premium bearings make these the fastest compact trolleys on the market, rated for speeds up to 75 mph. The premium bearings will last longer, increasing your ROI.

Impact Trolley Options

A key feature of the Impact Trolley is its versatility. We realized our customers had many different requirements in a zip line trolley, so we designed ours with maximum flexibility. There are four basic configurations available (shown below) and the Impact Trolley can also be used in a dual line zip line setup.

Each trolley option is available in either orange or silver anodized finish.
Impact Trolley

Basic Impact TrolleyThe Impact Trolley is the only zip line trolley designed specifically for impact braking. Its superior design and quality components make it the best of its class, and zip line operators can always add on features (hook accessory, T-handle, etc.) as their needs evolve.

Impact Trolley T-Handle

Impact Trolley with T-HandleAdding a handle to your trolley greatly improves the rider experience. The handle keeps riders facing forward with their hands free from the impact area (essential with impact braking) and pivots to smoothen the impact, swinging with the rider as they decelerate.

Catch hook

Impact Trolley with HookThe hook interacts with a catch mechanism on the brake trolley to prevent riders from rolling away from the landing zone, increasing throughput by allowing a guide to easily pull the rider to the platform. It even works with offset redirection lines.

Brake Trolley

Impact Trolley with T-Handle & HookThis option combines all of the benefits of the Impact Trolley, Hook Accessory (to help eliminate rider retrieval scenarios) and T-Handle (with knurled handles for maximum grip and stainless steel construction) – all in one package.

Why We Developed the Impact Trolley

After creating a high-quality zip line brake for the zip line industry, Head Rush looked at improving the next piece in the puzzle: zip line trolleys. Many trolleys were developed for use on tyroleans and not zip lines, so they didn’t fully meet the needs of zip line operators and guides. Head Rush trolleys are designed specifically for zip lining at high speeds and engineered with impact braking in mind. Zip line operators, guides, and riders will all benefit from the design features on our trolley.
