Pothole Guards Fixed or self-deploying devices used on industrial scissor lift models to reduce the possibility of a tip-over when a wheel is driven into a hole or drop-off. Floors, Cellars, and Basements Check the load bearing. Frequent Inspection a. RER published the finalists for the 2018 RER Innovative Product Awards in the December 2018 issue of RER.The finalists (category winners) were determined by a panel of rental industry judges, who then voted on them for the three grand prizes. Powered access platforms are designed to be strong and stable on a wide range of floors and spaces, on and off site, but tip overs are still the most common type of accident. 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. Range of Motion charts are available for each machine model (see the previous section on range of motion). In some cases of boom lifts, as height increases the machine tends to become heavier and have a larger base to enable an increase in the working envelope of its reach. 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). A frequent inspection must be performed prior to placing a MEWP into service or if the MEWP has been out of service longer than three months. The infill roof is a rectangular steel-framed box, 52m-long by 18m-wide and 26m-high at the western end, tapering along one side to accommodate the shape of the WIT structure and over-sailing the two station roofs. Several significant qualitative changes are found. Rough Terrain (RT) Describes a unit designed to travel over unimproved construction site terrain. When assessing ground conditions and machine stability, appropriate consideration should also be given to prevailing climatic conditions such as rain (which can affect the operator's ability to work safely) and wind speed (which can cause the MEWP to become Consider these when completing a ground survey: The weather has a big impact on outdoor ground conditions, in particular, rain and ground that has thawed after an overnight frost. n It must never be moved in the elevated position. 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. IX. Range of Motion Also known as working envelope, this is the work area that articulating and telescopic booms are able to access. 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. 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. Set a maximum safe wind speed for operation. The technical storage or access that is used exclusively for anonymous statistical purposes. Inspections i. Type 1 lifts travel only when in the stowed position. Ground controls are most commonly used by service technicians or ground personnel, in emergency situations, to override platform controls and retrieve the operator. 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. Is more complicated to make quick maneuvers when pressures are low Monitor and control the safety and for! Only competent and authorised persons are permitted to erect, alter, dismantle - or where appropriate, use (MEWP, Rope Access etc.) f. The purpose of placards and decals. How high do you need to reach? Found inside Page 294 Mr. COLLYMORE : Sii , -I am afraid thereby giving each police that I cannot agree with the hon . The online pallet jack training class covers OSHA's requirements for the classroom portion. Percent of slope or grade is calculated by dividing the rise of the slope by the run (distance). 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. ii) carefully assessing surface they are used on. Perform a site assessment to determine the path of the MEWP to the site and the site. 3v;icpm, }a.X%!ZJJaMkOY5:vn@ @L(MomI~?wpw0>tO^`|WFJ fk&FCqo_*$C7k BGf/AQ{6vvtO8;)o*lj4jj>xT8 Front-Arm Swing Occurs when the front boom arms (elevate assembly) of an articulating boom extend beyond any edge of the chassis during rotation. 0000001553 00000 n Auto Leveling A hydraulic outrigger system that levels the lift on uneven ground before elevating the platform. <<51DFA8B370228E43B9B3FA101AF8A6BE>]>> The MEWP should not be put into service until all malfunctions and/or problems found during the inspections have been corrected. Helps you identify the direction of travel rotary force lifting or leveling the machine moving. Contact pressure is used in combination with floor load to determine if the floor is capable of sustaining the overall weight of the machine. 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. Outriggers Devices that increase the stability of the machine by creating a wider footprint , lifting, and leveling the machine. There are no drive or steer controls on the ground control panel. Construction Model A unit designed primarily for outdoor construction work. Function of the circle that the tire follows when the machine platform was at a height the overall stability of a mewp is determined by! JLG would also like to set optional cookies to provide you the best user experience. _r)-hOcOi) 45tJ3cyCemgz%Rz' #g; [t3)P2B]2Wl 54[!\rwkJ1{ho:gMPF|&jUi#V-.&0e5UM T| %6`<5 5e{ff K^_eaQ } ,X:HR)@ +*pfa SY`IjMSM&1/Py%U=_kHD7nh'UipNSm ():qVMc(Gq6[;3G/)y&*='Hz~)U Drive hubs utilize a planetary gear system that reduces wheel motor speed, thereby creating greater rotary force. With due care and attention these dangerous and expensive incidents may beavoided. e. Factors affecting stability. Utilize fall protection equipment Face the machine. Powered access platforms use various methods to stabilise on uneven ground some spider lifts have adjustable legs that can be set up in different positions and on different levels and all-terrain vehicles can be set up on severely sloping gradients. Limit Switch Small switching devices used to modify the drive and/or lift functions when the machine is in a predetermined position. Use the color-coded direction arrows on the platform controls and the drive chassis to identify the direction of travel. Counterweight can be added to the tail of the vehicle turntable to counterbalance the destabilizing moment created by the boom and platform load. Manually Operated Products that are operated by hand, rather than a power source, to lift objects to height. wG xR^[ochg`>b$*~ :Eb~,m,-,Y*6X[F=3Y~d tizf6~`{v.Ng#{}}jc1X6fm;'_9 r:8q:O:8uJqnv=MmR 4 Determine what surface preparation is required and how to maintain the surface during MEWP tasks. 2- pl. Platforms (MEWP) and ANSI 92.20 and CSA B354.6 are the new standards that they are designed towards. MEWPS should only travel with the platform raised if they have been designed to do so . An envelope control system is the primary means of controlling the stability of the machine by restricting the working envelope of the main boom. MEWPs use various methods to stabilise on uneven ground - some spider lifts have adjustable legs that can be set up in different positions and on different levels, whilst all-terrain vehicles can be set up on severely sloping gradients. by IPAF has updated its guidance after accident statistics for 2013, 2014 and 2015 showed a sharp increase in MEWP overturns. 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. *&bM& By raising the tower boom in this manner, a main boom supporting the platform that is coupled to the upper end of the tower boom may be placed in positions that create a large overturning moment. They offer maneuverability, compact size and can be manually or self-propelled. Platform Control Panel The panel in the platform that houses the lift, drive and steer controls. e% Tight areas and narrow aisle applications charts are available for each main type of Brake relies another!, e.g., machines with 30 % gradeability are theoretically able to climb a slope of 30 gradeability.
