2.2.23. JACK WALER MK
The jack walers form the bogie of heavy-duty form
carriers. The bogie length can be adjusted at an
interval of every 0.5 m. The jack walers are fastened
together with 8 bolts M24 inserted into the D25
holes of their end-plate joints, thus creating a longer
jack waler profile.
The end-plate joints which determine the layout of
the form carrier structure at its base rest on the jack
walers. To the other side of the jack waler, the jacks
and the wheels to move the form carrier are
connected and fastened with 4 bolts M24.
2.2.24. WHEEL 100 MK
The Wheel 100 MK is used for the travel of heavy
form carriers. It is fastened to the jack waler that
forms the bogie with 4 bolts M24 at the indicated
positions.
The load-bearing capacity of the Wheel 100 MK lies
between 90-100 kN to move form carriers that bear
up to 360-400 kN (36-40 tons).
If the distance between wheel and bogie needs to be
increased, a spacer can be placed between them.
2.2.25. WHEEL 15 MK
The Wheel 15 MK is used for the travel of the
medium-weight form carriers. It is fastened directly
to the waler that forms the structure with 4 bolts
M16.
The load-bearing capacity per wheel is limited to 15
kN hence a 60 kN (6 tons) form carrier can move by 4
Wheels 15 MK.
2.2.26. TRIANGULAR BASE CARRIER 1500 MK
If there is not enough space for the support of the
form carrier at the base, it can be elevated with the
triangular base. It is mainly used for heavy-duty cut-
and-cover tunnel form carriers.
The top is connected to the end-plate joints of the
structure and the bottom to the bogie. Both joints
are fastened with bolts M24.
It has protrusions at both ends to stabilise and plumb
the structure at erection.
