HYDRAULIC WINDSHIELD SYSTEM HWS
1. PRODUCT DESCRIPTION
MK system is a product designed for heavy-duty structures, mainly used in civil engineering.
Its main feature is its versatility: gantry structures, cantilever trolleys, tunnel trolleys, shoring systems, horizontal and
vertical formwork, formwork supporting structures, climbing systems, façade protection structures and other
applications solutions can be solved by means of this product.
The basic component used in all these solutions is the WALER MK. Its versatile design and the specific accessories for
each application make it possible for the system MK to provide such different configurations.
Windshield System is another solution based on the MK system. Mainly focused on high rise buildings, its scope is to
cover the perimeter of level that is being poured and the previous two levels, by using a protection screen all around the
building. As the building takes height, the protection screens are lifted with crane or with an incorporated hydraulic
system.

HYDRAULIC WINDSHIELD SYSTEM HWS
The main scopes of a windshield system are:
Prevent people or objects from falling down from the edge of the slab.
Protection against wind, which enables to continue working even in adverse weather conditions.
Provides a platform for the works to be done at the edge of the slab.
Eliminates visual height effect for the people working in the building.
The windshield structure is based on the MK system (standard length walers with continuous hole configuration and
simple standard connections) providing great versatility when configuring different types of structures: structures
adapted to the required height level, different sections according to the jobsite needs, possibility to include different
types of working platforms, etc.
Each windshield set is made up with 2 vertical walers known as MAST, to whom the protection screen is directly or
indirectly fixed, and can also include WORKING or LANDING platforms.

HYDRAULIC WINDSHIELD SYSTEM HWS
Masts are the main walers of the structure. Each mast is made up of 2 profiles MK-180 spaced 52 mm and with MK
configuration in order to be connected to standard MK Walers when required.
Masts are guided by anchors, fixed to the building at any time (guided at 2 levels but resting just at one). The masts
transmit every erection effort to the building under construction.
The lifting of the HWS set, from one level to the next one, can be achieved using the crane or by the “Hydraulic System
HWS”.
If the stiffness of any complete assembly including protection screen and/or working platforms is not enough, additional
bracing elements such as tubes and couplers are added to the structure.

2.2. ELEMENTS DESCRIPTION
2.2.1. PROTECTION SCREEN
The versatility of the system permits using different
protection screens depending on the project
requirements: boards, nets, etc.
Following an example of a Protection Screen and its
elements:
Waler MK - Timber Beam Joint Detail:
In this case the SUPPORT is made by “Walers MK-120”
and “Timber Beams VM20”. The SCREEN is made by
board.
The ”Timber Beams” can also be fixed directly to the
“Mast” (element that we will see later)
Following the description of the main elements oaf a
protection screen:
WALER MK- 120
This is together with the MAST, the main element of the
HWS structures.
The 2 main uses of the walers are:
“Vertical Waler”: support for “Beams VM20” of
the “SCREEN”.
Horizontal support for “Beams VM20” of the
“PLATFORMS”.
Its main feature is the double row of holes that allow
the connection of the different parts that make up the
HWS structure in function of the requirements of each
jobsite.
They are made up of “Profiles MK-120”spaced 52 mm
and “Spacer tubes”. Spacer tubes and bolts are included
in the item.

SPACER TUBE MK-120/52
This component is used when joining 2 profiles MK-180
or MK-120 spaced 52 mm. The connection is made with
2 bolts M16x90 and 2 nuts.
SELF-CLIMBING BLOCK LT HWS
This element withstands the weight and vertical loads
acting on the windshield system HWS. Also is used as a
pushing element during the hydraulic lifting process.
It is assembled between the “Profiles MK180”with 3
“Bolts M16x90”and 3 Nuts. It is possible to assemble
the block in the 2 positions because is symmetrical.
There is always one “Self-Climbing Block LT HWS”
resting on the “Pawl“ of the “Head LT HW”, which
transfers the forces to the anchoring support.
The number of blocks in the masts varies depending on
the climbing procedure:
Crane lifting: it is necessary only one block per
section to support the HWS set.
Hydraulic lifting: several blocks separated 500mm
are necessary to climb the HWS set from one level
to the other.

DIVIDED MAST
It is always advisable to use “Entire Mast” (Profile MK-
180 in one piece) in order to assure the stiffness during
the climbing process. Nevertheless, it is possible to
achieve another mast lengths joining various “Profiles
MK-180”.
For that purpose, “Orthogonal Joint MK-180” with an
additional “reinforcement waler” can be used.
ORTHOGONAL JOINT MK
Item used to join longitudinally “Profiles MK-180” to
achieve other waler lengths.
It is fixed with 12 “Bolts M16x90 (0241690)". 4 “Bolts
M20x90 (0242090)” can be added when it is necessary.
It is recommendable to do this joins between profiles in
a staggered way in order to reduce de initial
deformation of the waler.
Mast division decreases considerably the
resistance of the mast comparing with the entire mast.
MAST REINFORCEMENT ADDITIONAL WALER
To reinforce the “divided mast”, an “additional Waler
MK-120” can be added parallel to the mast at the
“Orthogonal MK-180” join area.
This waler is fixed to the mast using following elements:
The additional waler must be joined in two points as
further apart as possible from each other, at both parts
of the mast.

2.2.4. ANCHORS LT HWS
The main function of the anchor brackets in the system
is guiding and supporting the HWS Windshield Sets.
The anchoring system is made up of 2 independent
parts:
HEAD LT HWS: main part of the anchoring system
that contains the mechanisms for guiding (by means
of detachable Claws) and the support for the
climbing set (Pawl).
BRACKET LT: element of the anchoring system to fix
onto the slab or onto the wall.
The “Head LT HWS”is connected to the “Bracket LT”,
thereby linking the windshield to the slab or wall of the
building structure
This is the SLAB anchoring system:
This is the WALL anchoring system:
HEAD LT HWS
This is the anchoring part, which contains the support
(Pawl) and the guiding mechanisms (Claws) for
“Windshield Sets”. As mentioned before, depending on
the jobsite’s application requirements, this head will be
assembled in the suitable bracket by means of a
“bracket connection”.
The “Pawl” is the part where the whole climbing
structure rests. Its main function is to allow the
movement of the “Self-Climbing Blocks LT HWS”
upwards being completely blocked on the way down.

The “Claws”are the parts in charge of transferring the
horizontal forces that arise on the climbing assemblies.
They also guide the mast all along the height of the
building. These claws go around the mast inner wings,
blocking the horizontal movement of the assembly or
protection screen but letting it slide vertically.
Claw assembly is made up of 2 swivel claws. A vertical
“double pin”connects them and at the same time fixes
them to the head’s frame.
Except for anchor recovery, claws must always
keep closed with the “double pin” locked with “Cotter
pin R3”.
For anchor recovery claws will open as shown in the
next pictures.
Unlock the Claws:
Open the Claws:
Note: Claws are closed following the steps in the
inverse order
Finally, the “Cylinder Connection Pin” is used for joining
the “Cylinder HWS” to the Head LT HWS as shown later.
