The Pros and Cons of Different Zip Line Brakes
There are two main categories of zip line brakes: active and passive. The type of brake you choose will dramatically affect your business’s risk management and the life span of your zip line materials. Active zip line brakes depend on the rider to initiate the braking process. Passive zip line brakes automatically activate without the rider or a guide doing anything. While active brakes may give riders more participation in the experience, it introduces additional risk.
Key takeaways
- Risk reduction: Passive brakes remove the responsibility from the rider, significantly lowering the risk of injury and operational liability.
- Throughput efficiency: Systems like magnetic brakes reset automatically, minimizing downtime and increasing your park's revenue potential.
- Predictable deceleration: Advanced passive systems self-regulate resistance based on participant weight, providing a smooth stop for riders of all sizes.
- Equipment longevity: Relying on friction-free magnetic braking drastically reduces wear and tear on your cables, trolleys, and braking components.
- Emergency backup: Spring brakes serve as excellent, ACCT-compliant emergency arrest devices when paired with a primary magnetic brake.
Active Braking
Active braking methods require deliberate participant action, increasing the risk of user error.
The most common types of active zip line brakes are leather gloves and brake pads. Participants must intentionally press a glove or brake pad against a zip line cable in order to slow down. Active brakes substantially increase the risk of injury because it is easy for participants to get lost in the adrenaline of the moment and forget braking instructions.
Furthermore, active brakes force the rider to place their hands close to fast-moving components. This proximity alone increases the risk of friction burns or more severe injuries if a hand gets caught in the trolley. When using active braking methods, inexperienced and overwhelmed riders face the highest risk. If a rider faints or loses composure, they cannot brake themselves.
If riders choose to brake too early or too aggressively, they fail to reach the platform. The entire group must then wait for them to haul themselves to the end of the line. Premature braking destroys the efficiency of your operation. Additionally, active brakes rely entirely on friction, which increases wear and tear on crucial zip line components, forcing more frequent replacement of cables, gloves, and brake pads.
Passive and Magnetic Braking
Passive braking methods automatically activate even if the participant suffers a breakdown and is unable to stop themselves. This fundamental risk management advantage makes passive brakes far superior to active ones. Among passive systems, magnetic brakes like the zipSTOP are in a tier of their own.
The zipSTOP uses eddy current magnetic braking technology to eliminate the need for sacrificial friction components. This means virtually zero wear on internal braking cores and significantly reduced maintenance downtime. More importantly, magnetic braking provides a consistently smooth deceleration by self-regulating braking resistance for each individual. A 15kg child and a 115kg adult will both experience the same comfortable deceleration.
To further optimize your ziplines and zipwires, magnetic brakes automatically reset after every use. This eliminates the chance that a guide might forget to reset the brake and heavily reduces waiting time between riders. When paired with compatible catch mechanisms and impact trolleys, rider retrieval becomes rapid, drastically increasing your facility's total potential revenue.
Magnetic eddy current brakes self-regulate resistance and automatically reset, maximizing both safety and throughput.
Gravity and Spring Brakes
A gravity brake relies entirely on line slack and an uphill trajectory to stop riders. They require a shallow slope and prevent the use of high-tension, high-velocity zip lines. Furthermore, waiting for riders to slowly ricochet back and forth to a stop kills throughput and wastes valuable terrain space that could be used for scenic runs.
Spring brakes use large metal coils that compress upon impact to absorb rider momentum. Unfortunately, they decompress and bounce the rider backward, causing further throughput delays. Because spring brakes cannot adjust their resistance, light riders face abrupt stops while heavy riders compress the spring intensely and rebound aggressively.
While inadequate as primary brakes, spring brakes excel as Emergency Arrest Devices (EADs). ACCT standards mandate EADs on lines exceeding 10 kph. When kept entirely independent from your primary magnetic brake, a spring brake provides a reliable, passive safety net against user error or extreme weather conditions.
Conclusion
Passive zip line brakes are categorically superior to active braking systems. The ability to eliminate the risk of participants injuring themselves through improper braking is invaluable for any operator's legal and reputational safety.
Among passive options, magnetic braking technology stands out as the premium standard in the adventure industry. It delivers an uncompromisingly comfortable braking experience, automatically regulates resistance, and boosts throughput with automatic resets. By utilizing magnetic systems as your primary brake and supplementing them with spring brakes as emergency arrest devices, you establish a highly efficient, safety-first environment for your guests.
