Helical Anchors, Inc. (HAI), www.helicalanchorsinc.com , with manufacturing and corporate offices located in Minneapolis, MN, supplied (41) 4.50” helical piles for the construction of the Allegan, Michigan zip line project earlier this year.

In order to support the 600 ft. zip line across the Kalamazoo River, helical anchors were chosen by structural engineers from Troy Garland Structural Solutions because of their easy and fast installation feature.

The required helical pile design capacity was 54 kips in compression and 36 kips in tension.  To provide the required helical pile design capacity, lead sections were designed with 14”-16”-16” x .50” helix bearing plates.  The average installation depth was 40 ft., and the crew from Ropes Courses, Inc. Were required to install some of the piles at a 15 degree batter.
