A Glossary of Common Mobile Elevating Work Platform (MEWP) Terms A Glossary of Common Mobile Elevating Work Platform (MEWP) Terms Safety is always job one on aerial worksites. A tight turning radius is important for congested industrial applications. This system is used on Genie trailer-mounted TZ-booms and some scissor (GS) products. However, if it is not given, it can be calculated if the currents, Ib (the base current) and either Ie ( the emitter current) or Ic (the collector current) are known. The two main boom angle sensors measure the angle of the main boom relative to gravity and are continuously monitored for mutual agreement. According to IPAF, stability is defined as "a condition in which the sum of the moments which tend to overturn the MEWP is less than the sum of the moments tending to resist overturning'. Maximum boom angles can create a situation of backward instability where the weight of the boom and the counterweight in the tail of the turntable can cause the machine to tip in the direction opposite the platform. users to select the correct machine and to Change is a common term used in health and safety, and some changes that come along are way overdue. Ce marked products are entitled to free movement throughout the European market ( EU and EEA ) means That lowers the center of gravity to improve safety and efficiency for MEWP design and use of MEWPs a. Inspect the machinery to make sure it is fit for use and ensure operators are fully trained Narrow (N) Units that are built to extra-narrow specifications to improve building access and maneuverability in tight or congested areas.

The person carrying out the demonstration must be trained and competent for example hold a MEWP Demonstrator licence. This switch guards against unintentional initiation of a function. It must also record any maintenance. There are two ways to control the envelope of the main boom: Mechanically and electronically. Aerial work platforms are now called "mobile elevating work platforms" or MEWPs Now, the new term is MEWP. Forward stability positions are the most critical when the main boom is extended near a horizontal angle and when the tower is fully raised in angle but retracted in length. Draw a cone (or the equivalent triangle, if working in 2D) with a) a half-angle of 18 degrees, and b) a tip placed at the overall center of mass. Roads in estates and residential areas may be less durable than those designed for commercial vehicles. In the new standards, MEWP classifications are made up of a combination of two key distinguishing descriptions: a) a MEWP Group. xref For example, to determine the slope grade, if the ground height (rise) changes 2 ft over a 10-ft distance (run), 2 ft divided by 10 ft equates to a 20% grade. The ground may settle when subjected to the loads of MEWP wheels or outriggers. Parking Brake: The system that keeps the machine immobile while parked. 0000003776 00000 n 2- pl.
