top rails must be between 36 - 45 inches above the platform surface.) Top rails must be capable of supporting at least 200 pounds applied in a downward or outward direction.
Most scaffolds and scaffold components must be capable of supporting their own weight and at least how many times the maximum intended load? C. 4 On scaffolds, federal regulations require fall protection be used when the height of a platform is more than how many feet above the lower level?
Mobile scaffolding must be capable of a variety of tasks, its main feature is that it's bearing surface must adapt to different conditions. 在按本发明的结构中,支承走行滚轮的横向构件(16)分为两部分,这些分段(16a,16b)相对于脚手架矩形的平面形状倾斜地互相连接,所以扩展横梁(15)可以沿两个互相垂直...
The fully planked platforms should be nominally 2 m apart, vertically, and remain in place until the scaffold is dismantled. The first platform can be up to 3 m above the ground or supporting surface, except for the access bay. Safe access must be provided up to the first platform and ...

He must be hurt. My son will be hurt, too!’ My Mom was like, ‘So what?’ Since then, I have never let my Mom stay in the same room with my son and friends. She would hurt children’s hearts (Ms. Bell, Latina, the occurrence of a problem). ...
The potential added value of enterprise modeling activities in that respect, however, can only be realized if the stakeholders are able to understand and use the respective means of representation [20]. The availability of the necessary skills must not be taken for granted [21] and must be ...
As indicated in FIG. 5, the depending bracket 18 can be dimensioned to permit the use of conventional boards as the support 22. For this purpose, the spacing between the side walls 20 of bracket 18 must be complementary in transverse width to the size of normal dimension lumber. A board ...
The compressive modulus of a composite scaffold depends not only on the porosity and pore size of the composite scaffold, but also on the content of the ceramic or glass added. It must be mentioned that only a few composite scaffolds presented in Table5were found to have the modulus that co...
Even if it is widely used, this autologous transplant is very invasive and does not avoid the formation of scar tissue [33, 34]. Moreover, the muscular wound size restoration is limited by donor site availability, since skeletal muscle tissues and other approaches must be thought for treatment...
