stream A stable machine has the envelope control system as one of its most important attributes. Outriggers generate high pressure at the feet which may not be supported by many areas of soil or unmade ground and even some paved areas, so additional foundations may be required. The boom and platform of the MEWP must not be used to move or jack the wheels off the ground unless the machine is designed for that purpose by the manufacturer. The relative stability of the folded versus the denatured depends on the environment of the protein. 0000003776 00000 n MEWPs can be stabilised and perform safely and effectively on most surfaces and gradients provided a few basic things are taken into consideration. There are two main factors which can prevent stability problems: a basic understanding of stabilising equipment properly and carefully assessing the surface they are used on. Most Genie articulating boom have zero tailswing, which is very valuable for tight areas and narrow aisle applications. The booms envelope is controlled electronically with sensors, whether they are length and angle sensors or load sensing devices. . Maintain 3 point contact with ladder/ hand rails (two hands, one foot OR two feet, one hand). Whilst power access platforms are designed to be strong and stable on a wide range of floors and spaces, whether on or offsite, the most common type of accident involving powered access platforms is still overturning. xTKSavv>V?
