Zipspeed™ Tandem Zipline Trolleys have 7075 Aerospace grade aluminium side plates, to minimise flexing and to provide superior wear resistance, whilst keeping the weight of the trolley to a minimum.
Fitted with special rubber-sealed, deep groove ball bearings as standard, chosen for optimal high speed, low frcition performance. the rubber seals retain the grease lubricant, whilst defending the bearings from moisture and contaminants: givinh the Zipspeed™ a lifespan of several thousand kilometres.
The Zipspeed™ Trolleys are fitted with a rubber brake-buffer (a replaceable wear item see KT075A), to absorb impact load at the end of the run, and have several choices of aperture for attachment to the lanyard, including a large central aperture which will accommodate a wide variety of karabiners and snaphooks.
The rear aperture can be used to attach a secondary lanyard. The small central hole (just above the ISC logo), can be used to attach an accessory bar/handle.
