Navigating zipline regulations for park safety

EN 15567 in Europe, ASTM F2959 in the US

EN 15567-1 sets the safety requirements for the design, construction, inspection and maintenance of ropes courses, including ziplines, and EN 15567-2 covers their operation; it is the reference for any European architectural plan. In the US, ASTM F2959 is the standard practice for aerial adventure courses, covering design, construction, operation and inspection.

The role of ACCT standards

The Association for Challenge Course Technology (ACCT) publishes the ANSI/ACCT 03 standard for challenge courses and aerial adventure parks in the US. Its requirements help builders establish proper clearance zones and reliable rider envelopes. Following them supports strict engineering tolerances and strengthens your position against liability claims.

Structural calculations and design review

Structural calculations show that the course geometry, cable tension and anchor loads are sound. A qualified structural engineer prepares them, and the inspection body reviews them before opening; in the US this takes the form of a PE-stamped design. This review is a prerequisite for commercial operation.

The commissioning process

The final commissioning process often reveals minor technical discrepancies. Facilities frequently need to fine-tune their braking systems for smooth deceleration across rider weights. Test runs with test weights before the inspection help confirm that the line performs as designed.

Daily and weekly inspections

Your ground staff are the first line of defense. Visual hardware checks every morning confirm that trolleys, harnesses and retraction lines are working. Proper record-keeping is critical: logging every equipment check gives a clear audit trail for your inspection body and local authority.

Training standards

Staff training and education follow recognized standards: ERCA in Europe, PRCA or ACCT in the US. Guides must be well trained in emergency rescue, harness fitting and guest communication. Investing in recognized training reduces the risk of human error on the course.

What are the safety standards for ziplines?

In Europe, commercial ziplines follow EN 15567; in the US, ASTM F2959 and ANSI/ACCT 03. These standards cover everything from structural design to daily operating procedures. Following the standard that applies in your location gives a reliable baseline of safety for all users.

Do ziplines need to be inspected?

Yes. Commercial ziplines need daily checks by trained staff and, under EN 15567-2, at least one main inspection a year, which many countries require from an independent inspection body. The inspector verifies cables, anchors and structural components. Local regulations can add further requirements.

Who certifies a zipline?

The inaugural inspection before opening is normally carried out by an independent (Type A) inspection body under ISO/IEC 17020. It reviews the structural calculations and carries out on-site functional tests. Routine inspections can also be done in-house by trained inspectors; local authorities rely on these reports for permits.

How often should a zipline be inspected?

Operators perform daily visual and functional checks before opening to the public. Under EN 15567-2, a main inspection takes place at least once a year, in many countries by an independent body. Keeping detailed logs of these checks is essential for long-term compliance.

What does the structural design review involve?

The structural calculations show that the attraction's design meets the required safety margins. A qualified structural engineer prepares them, covering dynamic forces, live loads and materials, and the inspection body reviews them; in the US this is a PE-stamped design. This review comes before the final commissioning.
