The Robertson Large Zip Tour Trolley combines the comfort of a handlebar and rugged durability of 2″ case-hardened wheels into an uncommonly long frame that increases stability. With multiple attachment points and ergonomic handle grips, this trolley is perfectly suited for exceptionally long zip lines.

The Large Zip Tour Pulley represents the most advanced design work using state of the art engineering techniques to build the safest and finest trolley for the ropes course industry. The 304 stainless steel frame is .101 thick for superior strength and trouble-free use. Unlike the competition it is assembled using machined 304 stainless axles, which may cost more but gives the Large Zip Tour Pulley unparalleled structural integrity. The sheaves are 2″ in diameter and case-hardened to 56-58 Rockwell and ride on sealed ball bearings to provide excellent wear characteristics in challenging outdoor environments. Safety is always a primary objective and the Large Zip Tour Pulley uses two additional back-up bolts should there be a catastrophic failure of the sheaves during use. These two extra bolts also give the Large Zip Tour Pulley superior stability. The long hang down plates keep the clients hands away from the cable while allowing the client to maintain body alignment with the cable. Handles are not meant to be hung from but rather to keep the client facing forward on the ride. Optional hook-in points allow various positioning of the riders, making this pulley the ultimate for adventure parks.
