Abstract

In recent years, reaching altitudes that are higher than your normal-height has evolved from pure amusement to an “in-demand” necessity out in the field. Means of achieving greater than normal height range from wooden poles to aluminum stilts. The era of ladders and other extension methods are slowly fading away. There are many designs in the market that focus on different factors to make a stilt. As other designs focus on one or two enhancements, the pneumatic leg extension’s objective is to improve all aspects of the stilt. This radical new design differs greatly from traditional stilt designs. The pneumatic leg extension focused on achieving the following advantages: simple operation, light weight, cost-efficient, sustain high weight capacity up to 280 lbs., 18 inches extension above the operator’s height, stability, Grip/shock absorption under slippery conditions and most importantly; safety. The pneumatic leg extension is mostly constructed with acrylic plastic, general rubber and aluminum. Overall, the pneumatic leg extension extended up to the proposed height and sustained an operator’s weight of 165 lbs. Further testing will reveal the device’s true potential. This device is designed to meet employers' standards and the operators' needs.
