PRODUCT DESCRIPTION
The MK System is a product designed for heavy-duty structures of high load- earing capacity mainly used in civil
engineering.
Its main feature is its versatility to configure all types of structures such as gantry structures, formwork carriers and
tunnel structures, shoring structures, horizontal and vertical formwork, other structures for formwork support,
clim ing rackets, sla perimeter protection structures and other applications.
The core item for all these solutions is the Waler MK. Its ela orated design and the com ination with various
accessories, oth unique of the MK system as well as shared with other ULMA products, ena le to adapt it to all
those a ove mentioned applications.
With the MK Structure system, two or more load- earing structures are formed in one direction, the so-called main
axis. These structures are raced to each other giving the required sta ility to the whole as well as a sor ing wind
loads acting on the structure in perpendicular direction to the main axis.
Depending on their field of application, mainly two structure types are distinguished:
−MK Truss Structure

−MK Form Carrier Structure

In the following, the two structure types are descri ed in detail.

MK TRUSSMK TRUSS
MK TRUSS
A truss structure, i- or multi-supported, supports the formwork and a sor s the loads acting on the formwork.
The formwork systems commonly used with the MK Truss Structure are Enkoform VMK or Enkoform H-120.
The typical truss form of the structure is achieved with equilateral triangles consisting of Walers MK and Nodes MK
assem led in the same plane. These structures are raced to each other with joints and tu es. Depending on the
required load- earing capacity of the truss, the main axis can e reinforced with push-pull props and tu es.
The Waler MK range allows assem ling trusses of different load- earing capacities. The most optimum load-
earing capacity-weight ratio is the one given y a distance of 3 m etween nodes axes and 2.6 m etween waler
axes.
