Cantilever or Needle Scaffolding

In this type of scaffolding the general framework may be of single or double type of scaffolding. But the standards are supported by needles or ties. These ties are projected out at floor levels or through openings or through holes provided in the masonry. Two types cantilever scaffolding are shown in Fig. 22.6.

This type of scaffolding is useful under the following conditions:

1. In situations where it has to be provided on a busy street so as not to disturb the traffic.
2. In situations where it is difficult to fix the standards on the ground.
3. In construction of tall buildings.
