Assess the ground conditions to be worked on to ensure the machine can be used to its optimum performance. 0000005355 00000 n Type 2 MEWPs can travel elevated and is controlled from the chassis. Also refer to Contact Pressure. A machine with this type of brake relies on another system to slow and stop. Procedures for special situations must be reviewed and approved by EHS. manufacturers will restrict the number of occupants on the unit when it does work outdoors. Many employers prefer online training because they know exactly what pallet jack training the operator will receive. Auto Leveling A hydraulic outrigger system that levels the lift on uneven ground before elevating the platform. Helps you identify the direction of travel rotary force lifting or leveling the machine moving. Use the color-coded direction arrows on the platform controls and the drive chassis to identify the direction of travel. The wind force also increases in proportion to the square of the speed. 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. 0000002860 00000 n MEWP is an acronym for Mobile Elevating Work Platform. In the meantime, take a look around to see whats new. Outriggers Devices that increase the stability of the machine by creating a wider footprint , lifting, and leveling the machine. Booms on an articulated lift are typically shorter than the boom of a comparable height straight lift. ii) carefully assessing surface they are used on. Platform height should not be confused with work height. Platforms (MEWP) and ANSI 92.20 and CSA B354.6 are the new standards that they are designed towards. 0000001553 00000 n Section on range of Motion ) keeps the machine the overall stability of a mewp is determined by system that reduces wheel motor speed, special attention paid. Analytix, Kinematic tool was used to study the stability of the machine. Terrainability Refers to a machines ability to negotiate terrain. Drive and Set A feature on the Genie TZ-50 trailer-mounted boom that allows the operator to drive the machine from the platform and set the outriggers for operation. Found inside Page 83These results may be interpreted as generalizations of the known Lyapounov theorem about the asyptotical stability by linear approximation. These new standards are much more similar to current standards used in other parts of the world, all of which are similar to the ISO 16368 design standard. "The required work height is an obvious and important selection criterion for MEWPs," says Owyen. Within ANSI A92, there are three standards affecting the MEWP user- the A92.20, covering machine design; the A92.22 covering safe use; and the A92.24 covering training. They offer maneuverability, compact size and can be manually or self-propelled. Mechanical limitations are typically reserved for smaller machines as straight booms can use linkages to restrict the envelope control. Also, remember to check if your indoor jobsite has power available. Envelope control is important to the industry because it provides the opportunity to make taller machines without the need to add excessive outreach and excessive weight. Perform safely and effectively on most booms are able to access normally is given when a. A written exam is included at the end of our online training courses. Narrow (N) Units that are built to extra-narrow specifications to improve building access and maneuverability in tight or congested areas. Stability Validation and Load charts for MEWP Machine: Stability and load chart creation for both Standard and Uncommon attachments. Drive hubs utilize a planetary gear system that reduces wheel motor speed, thereby creating greater rotary force. When designing a boom lift, vehicle weight is an important consideration because it affects manufacturing costs, vehicle maneuverability and safety factors. An envelope control system is the primary means of controlling the stability of the machine by restricting the working envelope of the main boom. The MEWP must not be positioned against another object to steady the platform. Drive Enable A system that warns the operator when the turntable has been rotated beyond the non-steer wheel. Any assembly of wires spun into a helical formation (either as a strand or a wire rope), when subjected to a tensile load, can extend in three seperate phases, depending on the magnitude of the applied load: Phase 1: initial extension. Many floors are unable to take the weight of a MEWP and could collapse without warning. Xu It must never be moved in the elevated position. Assess the ground conditions that you are working on to ensure you can use the machine to its optimum performance to help prevent avoidable stability accidents. When designing a boom lift, vehicle weight is an important consideration because it affects manufacturing costs, vehicle maneuverability and safety factors. Type 1 MEWPs can only travel with the platform in a stowed position. Percent of slope or grade is calculated by dividing the rise of the slope by the run (distance). , design, and other elevated work platforms more detailed information about the cookies jlg uses, see our Policy.
