Type 2 MEWPs can travel elevated and is controlled from the chassis. A MEWP is the product of activities that include design, production and testing, as well as the provision of information on the MEWP itself. 0000004628 00000 n The Company's diverse product portfolio includes leading brands such as JLG mobile elevating work platforms; JLG and SkyTrak telehandlers; and an array of complementary accessories that increase the versatility and efficiency of these products. Usually specified as a percent, e.g., machines with 30% gradeability are theoretically able to climb a slope of 30%. Stability Validation and Load charts for MEWP Machine: Stability and load chart creation for both Standard and Uncommon attachments. Therefore, the maximum horizontal outreach provided by the upper boom is typically less than the single boom of a straight lift. The demonstration does not qualify for training. White paper: ANSI 92.20 White Paper Part 2 Found inside Page C-413.6.14 Scaffold towers and modular access platforms may be used for inspection although they may not be as stable as fixed scaffolding. Grade Refers to the severity of the slope, usually measured in percent. Maintain 3 point contact with ladder/ hand rails (two hands, one foot OR two feet, one hand). Proximity to Excavations If the MEWP needs to be used close to the edge of trenches or excavations where the outriggers or wheels may be in the danger area, then an engineering assessment must be made by a competent geotechnical engineer before the MEWP is set up and operated. Your request for location has timed out. This is based on the premise that an individual standing in the platform with arms stretched overhead can reach areas 6 ft higher than the floor of the platform. standards , the HARRISON range of M.E.W.P.s Pedestrian - controlled Electric Next, proceed with observing how the .

Floors, Cellars, and Basements Check the load bearing. Aerial Lift Train the Trainer Certification. 6. Species Another specification to look at is the weight of the thumb and thumb cylinder, which directly affects the overall stability of the excavator, especially over the side of the machine. MEWPs can be stabilised and perform safely and effectively on most surfaces and gradients provided a few basic things are taken into consideration. Done to determine if there are any malfunctions. Therefore, be sure that your particular excavator can handle the weight of the thumb and cylinder. is the highest average answer. JLG uses necessary cookies to make sure our site works. Must be performed prior to placing a MEWP into service, if the MEWP has been out of s ervice longer than three months, or if the Spider platforms with outriggers should also be regularly checked for machine level especially if suspected that spreaders or mats may be sinking. Weather: high winds can tilt platforms and make them unstable. Ground condition assessment is also important for self propelled MWEPs such as booms and scissor lifts which may be driven along the ground with the platform raised. The Hy-Brid Lifts Push-Around Series is an example of a Group A, Type 1 lift, as it can only be pushed throughout the jobsite when in the stowed position. Smaller compact lifts are great options to choose when completing work indoors. The upper boom is pinned to the upright with its own lift cylinder which can be raised or lowered in angle with a full range of motion regardless of the position of the tower boom. 0000001770 00000 n A nation's stability, economic development, and overall growth are largely determined by the quality of its leadership. The envelope shape positions of stability and structural integrity can be controlled including the restriction of forward and rearward reach of the platform. Note: When the drive enable system is in use, the machine may drive in the opposite direction that the drive and steer control handle is moved. The following calculations can typically be done by hand or with CAD software. Two-wheel-drive scissor lifts usually drive with the front steer wheels. 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. Found inside Page 271A cage for hawks while mewing ; bence, a place of confinement, o- A stable. Many accidents or equipment damage happens when operators don't fully understand the equipment. Tailswing Occurs when the rear end of the turntable extends beyond any edge of the drive chassis when the lift is rotated. To determine stability: Calculate the center of mass of the overall assembly including all external loads. Terrainability Refers to a machines ability to negotiate terrain. The purpose of this Program is to establish safety guidelines for persons who operate, perform work on, or work near MEWPs. The MEWP's . Inspections i. Like straight boom designs, counterweight is added to the tail of the turntable to counterbalance the destabilizing moment of the upper boom and the platform load. Mechanical Envelope Control Found inside Page 257Psychosocial work stressors as antecedents of musculoskeletal problems: a systematic review and metaanalysis of stabilityadjusted longitudinal studies. Front-Arm Swing Occurs when the front boom arms (elevate assembly) of an articulating boom extend beyond any edge of the chassis during rotation. Maintenance A. These poor conditions may mean further support is required such as spreader plates, timber mats or concrete pads. 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. Floor level and scissor lift standards were released up a grade or with. MEWP Types Within each MEWP group are three types, determined by how the MEWP is able to be moved. MEWP Type is determined by whether the lift can travel when stowed or elevated and the location of the controls which allow such travel. Four-Wheel Drive Units that have power to all four wheels for extra rough-terrain capability. Stabilising the Mobile Elevated Work Platform. (CEN) to determine a suitable factor and stability calculation method for MEWPs have been adopted.

MEWPs can be stabilised and perform safely and effectively on most surfaces and gradients provided a few basic things are taken into consideration. determine if any components of the tasks or the work environment have changed and the effect that it could have on the safety of the operation. by Front-Arm Swing Occurs when the front boom arms (elevate assembly) of an articulating boom extend beyond any edge of the chassis during rotation. The MEWP should not be put into service until all malfunctions and/or problems found during the inspections have been corrected. Likewise, the position of maximum backward instability occurs when the tower is lowered to a near horizontal angle while keeping the upper boom raised at the max angle. Only competent and authorised persons are permitted to erect, alter, dismantle - or where appropriate, use (MEWP, Rope Access etc.) "The required work height is an obvious and important selection criterion for MEWPs," says Owyen. Whether you are new to the aerial industry or you could use some quick reminders, knowing terminology associated with mobile elevating work platforms, or MEWPs, can help avoid expensive mistakes on aerial jobsites. Narrow models are generally heavier, due to increased counterweight. Transom spacing is determined by the thickness of the boards supported. Manually Propelled Products that must be physically pushed or pulled to move. A primary motivation of this work was to determine to what extent the predictions of the electronically more realistic GGA+U treatment would differ from those obtained within the GGA. Electronic Envelope Control A position of maximum forward instability for this type of boom is encountered when the tower is raised to its full angle with the upper boom near a horizontal angle. The main boom length sensor measures the length of the main boom and is monitored for response to the main telescope command and for agreement with the fixed position length switch. 431 0 obj<>stream Floor surfaces the rapid growth of its electric vehicle business over especially if suspected that spreaders or mats be! Often used as part of the model name. Level/Tilt Alarm An audible warning automatically activated by a sensor when the machine is tilted beyond allowable operating tolerances (does not automatically disable use of the machine). Drive hubs utilize a planetary gear system that reduces wheel motor speed, thereby creating greater rotary force. Although the smaller N Units are able to withstand more than this value with height. In the new standards, MEWP classifications are made up of a combination of two key distinguishing descriptions: a) a MEWP Group. The width of aerial work platforms is a critical factor in maintaining stability. Determine what surface preparation is required and how to maintain the surface during MEWP tasks. There are two ways to control the envelope of the main boom: Mechanically and electronically. Workplace Inspection An inspection of the worksite performed by a qualified operator prior to each use to identify workplace hazards to avoid while moving, setting up and operating the machine (see the previous section on safety). 0000002519 00000 n An envelope control system is the primary means of controlling the stability of the machine by restricting the working envelope of the main boom. 0 In all, the dynamic stability of the MEWP can be calculated accurately by ADAMS, in the meantime, the overload operation test (1.5 times rated load) must be performed on the 5 cross slope before the MEWP are selled, and so long as the minimum dynamic stability safety coefficient is no less than 0.1, the MEWP are proved stability and safety.
