Emergency Arrest Device (EAD)

A zipline Emergency Arrest Device (EAD) is a critical safety component on ziplines. It acts as a backup braking system designed to stop a rider safely in the event of a malfunction with the primary braking system.

Here’s a breakdown of how EADs work:

• Function: When the primary braking system fails, the EAD is triggered automatically or manually, depending on the design. It engages a braking mechanism that utilizes friction to slow down the rider progressively until they come to a complete stop.
• Importance: EADs provide an extra layer of safety for zipline riders, minimizing the risk of injuries in case of primary brake failure.
• Types of EADs: There are various designs for EADs, but some common types include:
  • Friction Mat EADs: These use a mat or pad that presses against the zip line to create friction and slow down the rider.
  • Airbag EADs: These deploy an airbag that expands rapidly to create air resistance and stop the rider.
  • Spring-loaded EADs: These utilize a spring-loaded mechanism that engages a braking bar or similar device to arrest the rider.
