Range of Motion charts are available for each machine model (see the previous section on range of motion). 4.3.1Aluminium Alloy Work at Height Equipment/Components Tailswing generally exists on all telescopic booms and some articulating booms. The width of aerial work platforms is a critical factor in maintaining stability. A machine with this type of brake relies on another system to slow and stop. Self - propelled or U.K. and E.E.C. This applies to both road towable and vehicle mounted platforms. 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. =}fw)E0>i|r~^:I.D"y[1t5~?s KzJj{Sf_y.($"GI^"h_:wzO;JV%vz8P-}xT)yl/F/S,F^#'iP\x*&:*Z-:(![yu2MS 7TeH&~x[pL|Kvm % Narrow (N) Units that are built to extra-narrow specifications to improve building access and maneuverability in tight or congested areas. Two-wheel-drive scissor lifts usually drive with the front steer wheels. Ground conditions have a big impact on the stability of MEWPs and as part of the risk assessment, a ground survey should be completed before every job. fall protection, movements of the MEWP, load changes, stability changes). Underground services such as sewers, drains, manholes, gas and water mains might be damaged by the weight or could even collapse. Refers to the severity of the slope, usually measured in percent.
