Zip World has opened the doors to its new VELOCITY 2 ride! Satisfying the public’s growing appetite for adrenaline-fuelled experiences, Zip World aims to put even bigger smiles on more faces, with four new low-noise lines, with riders reaching speeds of up to 125mph!
To achieve this, ISC has worked closely with Zip World to design and manufacture a trolley that is capable of performing at such incredible speeds, whilst suspended 500ft in the air. The trolley has to be capable of repeating this feat over and over, as demand is expected to be high.
From the outset Zip World wanted to tackle the issue of sound emissions, taking a pro-active approach to reducing the noise generated from its zip lines and considering the effect on local residents and wildlife. Noise reducing systems play a pivotal role, when looking to grow the number of zip lines at any one location, as the more lines in operation, the more sound produced. We relished the challenge and set about the task of developing the means of making the ZipWorld Velocity 2 Trolleys run near silent, whist maintaining the key design features which make it such a successful and integral part of Zip World’s offering.
The solution was to utilise a unique Polyurethane (PU) “tyre”, which is fitted to the Stainless Steel wheels of the trolley. This additional element to the wheel, replaced the “steel on steel” principle (the main sound contributing factor) of the standard model. We also modified the trolley casing, crafting carefully shaped and positioned holes, allowing sound to dissipate, without being amplified by the side plates of the trolley.
These modifications have meant a reduction in sound emissions of 15dB, resulting in the successful application to open more Zip lines at the Zip World Velocity 2 site!
