Zip Lines

---

 A single zip line is a standalone ride from point A to point B. A canopy tour or zipline tour is an integrated, sequential experience where participants navigate through a forested environment via a series of connected zip lines, suspended aerial bridges, and elevated platforms, often without touching the ground until the end of the tour.

 Our qualified designers and/or licensed structural engineers meticulously calculate the exact vector forces, cable sag, tension, and rider aerodynamics. We design the slope and sag to ensure participants reach the landing platform at a safe, thrilling, and easily managed speed, factoring in varying participant weights and environmental conditions.

 Safety and compliance are our foundational priorities. ESI designs, engineers, and builds commercial canopy tours to meet or exceed the stringent safety standards set by the Association for Challenge Course Technology (ACCT), the Professional Ropes Course Association (PRCA), and ASTM F2959. 

 Typically, yes. Elevated platforms, launch decks, landing towers, and staircases alter structural loads and generally require municipal construction permits. ESI's licensed structural engineers provide the necessary 2D blueprints, site plans, and load calculations required to help you successfully navigate your local regulatory and permitting process.

 Yes, we specialize in tree-based installations. When utilizing natural supports, we perform comprehensive holistic health assessments to ensure the trees have the proper root collar integrity, healthy bark, and adequate load-bearing capacity to safely anchor the dynamic forces of a zip line.

 If your site lacks mature, healthy trees, ESI can construct hybrid systems or fully artificial structures. We regularly design and install sprawling canopy tours using engineered, pressure-treated wooden utility poles or custom-fabricated galvanized steel towers to achieve the height and distance your tour requires.

ESI relies on primary and secondary brakes that do not require the rider to do any braking. We do not build hand brakes, as relying on a participant's grip strength and a short training session is insufficient to prevent incidents. Instead, we install advanced, hands-free systems like the zipSTOP or zipKEA, which provide smooth, automated deceleration for riders of all weights.

Timelines depend heavily on the length of the tour, terrain access, and local permitting. Engineering and permitting typically take 2 to 3 months. Physical construction ranges from a few weeks to several months. Total project time from initial design to grand opening averages 4 to 12 months.

 Yes, ESI offers complete, turnkey equipment packages. We supply everything your operation needs, including zip line-specific full-body or sit harnesses, tandem pulleys, impact-rated helmets, and heavy-duty lanyards, sourced directly from trusted industry-leading manufacturers. 

Trees are dynamic, growing structures. Facilities must regularly monitor tree health for root rot or insect damage. ESI provides specialized ongoing maintenance to manage "bolt overgrowth," safely backing off hardware and adjusting cable tension to prevent tree constriction and maintain the system's structural integrity. 

Yes. A safe canopy tour requires highly competent guides. Our AEE-accredited training department provides comprehensive, site-specific instruction. Your staff will learn how to manage safe platform launches, operate specific braking systems, perform mid-line high-angle rescues, and execute daily operational safety checks.
