3. 0.1NEEDLE SCAFFOLDING:-
Needle scaffolding is used under the following circumstances:
Ground is weak to support the standards.
Construction of upper part of the wall is to be carried out.
It is required to keep the ground near wall, free for traffic etc.
In this type of scaffolding, the general framework may be of single scaffolding Or of double scaffoldling type. But the standards are supported by a series of needles Which are taken out at floor levels or through holes kept in the masonry.

5. 0.1.1Needle-Beam Scaffold
A  needlebeam  scaffold  consists  of  a  plankplatform  resting  on  two  parallel
  horizontal  beams,called  needle  beams,  which  are  supported  by  linesfrom
 overhead. (See fig )Needle-beam scaffolds should be used only for the support  of  personnel doing  light  work.  They  are suitable for use by riveting gangs
working on steelstructures  because  of  the
 frequent  changes  of  locationnecessary  and  the  adaptability  of  this  type  of
 scaffoldto  different  situations

6. .Several   types   of   patent   and   independent scaffolding   are
 available   for   simple   and   rapid assembly,   as   shown   in   figure   6-41.   The scaffolding uprights are braced with diagonal members, and the working level is covered with a platform of planks. All bracing must from triangles, and the base of each column requires adequate footing plates for bearing area on the ground. The patented steel scaffolding is usually crected by placing the two uprights on the ground and inserting the diago nal members.

7. The diagonal members have end fittings, which permit easy assembly
The diagonal members have end fittings, which permit easy assembly. The first tier is set on steel bases on the ground, and a second tier is placed in the same manner on the first tier with bottom of each upright locked to the top of the lower tier. A third and fourth uprights can be placed on the ground level and locked to the first set with diagonal bracing. The scaffolding can be built as high as desired, but high scaffolding shoud be tied into the main structure.

9. 0.2 TRESTLE SCAFFOLDING
The quikally tresatle ladder scaffold is one of the most innovative solution on the market. It is quick to erect and provides a safe, highly secure work platform. It is also easily relocatable on – site with no need to fully dismantle it - hardrail posts and outriggers need only be adjusted to the new location.

10. 0.2.1Safely in Action
Well engineered design basics provide a safe work environment. The system is quick and easy to assemble, with a minimum amount of components that easily fit together. The flexibility of the scaffold design allows parts like the handrail posts to be mounted on the trestle with one simple movement.
Plank Locks are designed to sit flush with the connecting planks maximising strength & ensuring a safe, sturdy & stable 450mm platform
Outriggers are necessary for higher working platforms, where the platform height is greater than 3 times the base width of the trestle.
