KSP SHAFT PLATFORM
These chains are directly fixed on the waler by a
E20x70 pin (this pin will be an extra pin different to
the ones used to fix the Gravity pawl bracket). In case
it is necessary to assemble the chain in the area where
the Gravity pawl is located, the Ring A16 has to be
used.

Board assembly
The platform structure is covered by 3-layer timber
boards or timber planks
It is recommended to adjust the board taking into
account that the distance from its edge to the wall will
be approximately 50mm.
3.1.6.
Perimeter protections
In case of fall risk from any of the platform’s
edges, it
is necessary to install perimeter protections handrails.
It is convenient to install the handrail support while
assembling the beams and before covering them with
the board. Once the VM handrail support is installed
by a Short pin 0.35m and hexagonal nut 15, and the
platform is covered with boards, toe boards and
ledgers can be fixed to these supports.

MAIN PLATFORM PERFORMANCE
The first pour of the shaft to build is done supporting
the formwork directly on the foundation. This
formwork has to include the boxes or cones (in the
case of Folding Bracket), used to support the main
platform in the following pouring step.
Depending
on if boxes or Folding brackets are used,
there are different solution possibilities:
It is possible to join two CHAIN 2G LT/842
(0306003), extending the total length.
