BOSTA 100A tower of strenght
2
Broadening dimensions
The extra-class scaffold
Heavy loads, easy going
Let the facts speak for themselves:
area loads of up to 600 kg/m2, part
area loads of up to 1,000 kg/m2.
In practical terms this spells packs
of bricks of up to 900 kg plus a
workman and his tools. This adds
up to over 1,425 kg on a BOSTA
100 horizontal frame measuring
2.50 m in length. Exceptional values
enabling you to handle exceptional
projects exceptionally well.
Whenever it’s a matter of extra heavy loads, extra tall heights
and extra space to move around in, BOSTA 100 is the ideal
scaffolding system. This 100 cm wide frame scaffold has all the
attributes for safely coping with the toughest challenges: the
finest material, the finest workmanship, and the finest technology,
as well as the dimensions to match. BOSTA 100 opens up
new dimensions in scaffolding: more efficiency, more safety, and
more for your money. Make the most of its vast potentials!

Top of the class in every class
BOSTA 100 meets all the requirements of
DIN 4420 in scaffold classes 4, 5 and 6.
Plus of course the safety regulations of the
German workmen’s compensation insurance.
Buy low, work high
BOSTA 100 bears maximum loads with
maximum safety, even beyond the standard
design height of 24 m. Despite this, all the
individual parts are not overweight and they
handle easily. No risk of injury from protrud-
ing parts thanks to self-locking gravity flips;
self-aligning, systematically perpendicular
assembly, with plank retainers a standard
feature. Another reason why the BOSTA 100
scaffold is a class apart.
BOSTA 100 is a scaffold system that best
meets construction site requirements tech-
nically and economically.
One for all
With a width of 100 cm and all the associated
advantages, BOSTA 100 is the ideal working
scaffold, and roof and protective scaffold, and
bricklayer’s scaffold, where again it is in its
element. And a room scaffold for large tall
rooms. As you will soon see, the BOSTA 100 is
unbeatable for its versatility.
Brawn and brains
Backed by decades of scaffold manufacturing
experience, one thing is for us absolutely
essential in the development of our products:
they must be both safe and easy to handle.
Which is why they are all of modular design,
the BOSTA 100, too. Just a few basic elements
combined with the right accessories and you
have tailor-made solutions. Base jacks, horizon-
tal and vertical frames, guard rails, planks,
diagonals all in practical dimensions. Platform
widths from 1 m to 2 m and bay lengths from
1.25 m to 3 m. Plus the brilliantly conceived
accessories and the system is ready to cope
with almost any challenge. And, it might inter-
est you to know that many BOSTA 100 parts
are compatible with the BOSTA 70 or the
MODEX junction scaffold.
Quality that pays
Proverbial Hünnebeck quality is also reflected
in the BOSTA 100. Anything made of steel is
hot-dip galvanized on the inside and out, any-
thing made of wood is impregnated against
rotting, the aluminum parts never change
shape. Combine all these advantages and
you’ll find that the BOSTA 100 is a scaffold that
always pays. And if you consider our after-
sales service, financing and upgrade options,
you’ll very soon agree that BOSTA 100 opens
up not only new dimensions in accessing but
also in cost efficiency. Work it out for yourself!

It all adds up
Reaching up to class 6
Current DIN 4420 standards categorize
scaffolds into six classes depending on
maximum permissible loads. In choosing
the type of plank, you yourself determine
the maximum possible load and hence
define the class the scaffold belongs to.
Our system contains planks for classes 4 to
6. A width of at least 95 cm is 5 cm wider
than the standard requires. Refer to the
following table for a list of all the scaffold
classes and maximum permissible loads.
Class Min. plank Effective Surface
surface weight/ pressure
width unit area
m kg/m2 kg/m2
1 0.50 m – –
2 0.60 m 150 –
3 0.60 m 200 –

BOSTA 100
Sample calculation for using
the BOSTA 100 in class 6.
Effective weight
Platform area of a scaffold bay:
2.50 m x 0.95 m = 2.375 m2
Max. permissible load in class 6:
600 kg/m2 x 2.375 m2 =1,425 kg
per platform area
Calculating the envisaged load
in this example:
Worker 100 kg
Pack of bricks 900 kg,
900 kg x 1.2
(crane factor) 1.080 kg
Mortar bucket
0.6 m dia (100 l) 210 kg
Tools 10 kg
Total 1.400 kg
The effective weight of 1,400 kg
calculated in this example
remains 25 kg beneath the
maximum limit of 1,425 kg.
Part surface pressure
To calculate the maximum per-
mitted load in scaffold classes
4, 5 and 6, it is also necessary
to work out the part surface
pressure to make sure that even
locally concentrated loads do
not cause the planks to break or
buckle. In scaffold class 6, a
surface pressure of 1,000 kg/m2
must not be exceeded.
� Pack of bricks
Ground area
1.25 m x 0.75 m = 0.938 m2
Weight 900 kg
Surface pressure
900 kg/0.938 m2 = 960 kg/m2
The surface pressure of
960 kg/m2 is below the maxi-
mum limit of 1,000 kg/m2.
� Mortar bucket
Ground area 0.28 m2
Diameter 0.60 m
Weight 210 kg
Surface pressure
210 kg/0.28 m2 = 750 kg/m2
Here, too, the 750 kg/m2 is
less than the maximum limit
of 1,000 kg/m2.
Such load-bearing capacity
makes BOSTA 100 the strongest
scaffold on the market, and one
of the most economical of all.
In scaffold class 5, the pack of
bricks may weigh up to 535 kg
and the additional load of the
worker, mortar bucket and tools
will not exceed the permissible
plank area load of 1,069 kg.
In scaffold class 4, the pack of
bricks may weigh up to 300 kg.

Pick your plank
An option for every need
BOSTA 100 planks come in a
variety of types and lengths for
a variety of loads. Used with a
vertical frame, the 2.5 m planks
belong to the following scaffold
classes:
Scaffold class 4
Timber plank 250/32
Hollow box plank 250/32
Scaffold class 5
Steel plank 250/32
Scaffold class 6
Horizontal frame 250/100-6
Aluminum stage 250/32
Aluminum stage 250/50
Whether as working or protective
scaffold, picking the right plank
enables you to cope with any
construction site situation while
conforming to the respective
scaffold category requirements
according to DIN 4420. Always
in line with the rules.
A bear for wear
The planks are working surfaces
for foot traffic which also act as
self-bracing structural elements.
All of them have hard-wearing
attachment hooks which clip
easily, quickly and safely onto
the vertical frames. All of them
are suitable as the top level of
protective and protective roof
scaffolds and all of them are
compatible with BOSTA 70.
Hünnebeck has an impressive
array of plank options in
various materials, lengths and
widths to cater for every need.
You’re always standing on
„solid ground“, whether you
opt for timber, steel, aluminum,
or a mixture.
Timber plank, 32 cm wide
Hard-wearing and durable
since the wood is impregnated
for lasting protection against
weathering and rot. Three ad-
jacent planks form one working
platform. The planks may be
used on either side and are
compatible with the 35, 70 and
100 enlargement brackets.
Horizontal steel frame,
100 cm wide, with individual
wooden planks
If it’s a matter of maximum
loads at very economical prices,
this is an option preferred by
the building trade. The horizon-
tal frame with a length of 2.5 m
accepts a load of over 1,400 kg
and still has safety in reserve.
This can also be seen from the
sample calculation on page 5.

BOSTA 100
Steel plank, 32 cm wide
Long-life planks made of hot-dip
galvanized, high load-bearing
steel, with a perforated, non-slip
surface. Uncontrolled load
accumulation is avoided since
small pieces of rubble or sand
perculate through the perfora-
tions. In lengths of 125, 150,
200, 250, and 300 cm.
Hollow box plank, 32 cm wide
Amazingly light, one-third less
weight than a comparable
timber plank, but with the same
load-bearing capacity. Comes
with an aluminum-zinc coated
steel sheet design with slip-
resistant lateral beads on the
surface. Convenient assembly
handles on the underside.
In lengths of 125, 150, 200, and
250 cm.
Aluminum stage, 32 cm wide
Combines lightweight with high
load-bearing capacity up to
scaffold class 6. May be used
on either side, as both sides
have the same non-slip surface.
In lengths of 125, 150, 200,
250, 300, and 400 cm.
Alumimum stage, 50 cm wide
The lightweight plank with the
highest load-bearing capacity
for scaffold and bracket levels.
At 50 cm, the ideal platform
width on brackets for bricklay-
ing. Designed for the 50 cm
enlargement bracket with in-built
plank retainer. May also be
attached to the bracket at the
plank level with a scaffold class
6 load. Length: 125, 200, 250,
and 300 cm.
Bricklaying with BOSTA 100
Ergonomically, bricklaying can
only be done up to a height of
around 1.5 m above the working
platform. The standard BOSTA
100 range includes enlargement
brackets 50 and the 50 cm wide
aluminum stage for taking the
effort out of bricklaying.Simply
mount these at the convenient
working height between the
scaffold platforms. For non-tiring,
ergonomically correct, fast and
time-saving work.
What’s more, just as the scaffold
platform, this bracket platform
will accept loads up to class 6
for positioning at the same
height.

Straight to work
Straightforward erection and dismantling
Always on the level
Ground irregularities and an-
gled terrain are no problem for
BOSTA 100. The product range
allows for three different height-
adjustment methods. Accurate,
professional, and safe. Only
the first stage has to be aligned
as precisely as possible.
All the others are automatically
aligned when installing the
diagonals at the fixed points.
� Base jacks
A simple way of compensat-
ing for any unevenness on the
supporting ground. The easy-
to-adjust base jacks have an
adjustment range of up to
50 cm.
� Adjustment posts
With an adjustment range of
30 to 130 cm, the adjustment
post has a meter of play to
cope with major height differ-
ences or gradients. It con-
nects easily and safely to the
vertical frame.
� Vertical frames
Height adjustments can be
made with the 100, 150 or
200 cm vertical frames.
Together with the base jacks
and adjustment posts, the
base of the scaffold adjusts
with millimeter precision.
Getting a grip
The vertical frames have conve-
nient internal forked bolts with
gravity flips for rapid and safe
connection with guard rails,
diagonals and toe boards.
These self-locking fixed points
create strong, positive joints.
Ingeniously conceived
On scaffolds with protruding
parts, injuries are only a question
of time. And the parts them-
selves are quickly damaged.
Impossible with BOSTA 100.
Neither does the system have
any detachable small parts that
easily get lost or special parts
for the base area. All to your
advantage!
Convenient, fast and safe,
time-saving and cost-efficient
—this sums up the assembly
of the BOSTA 100. Bolt-free,
self-aligning plug-and-socket
connections, so nothing
can go wrong. All the parts
will only fit in the prescribed
sequence. Making correct
assembly inevitable!

Wonderful at wandering
BOSTA 100 can be simply dis-
assembled bay and storey-wise
on one side and re-assembled
on the other. Let BOSTA 100 do
the wandering and you’ll save
on scaffolding material and
inventories. The cost savings
are significant.

1. Turning the spindle nut
allows precise alignment of the
bottom scaffold bay. The diago-
nal fits neatly over the bottom
gravity flip and braces the bay.
All further bays are then auto-
matically perpendicular.
2. The rounded 15 cm long
insert pieces hold the vertical
frames, with no threaded joints.
3. The guard rail is attached
at back and knee height with
self-locking gravity flips.
4. Clip the internal diagonals in
place at the top. Slot the hook
into the recess on the U-section
and lower the other end of the
diagonal.
BOSTA 100
5. The vertical frame is automat-
ically straightened when the
bottom end of the diagonal is
pushed over the bottom gravity
flip. No need for any tools! One
diagonal for a maximum of five
scaffold bays.
6. Push the scaffold’s side and
end toe board against the up-
right tubes of the vertical frame,
this secures the working plat-
form.
7. Lay the planks (horizontal
frame, metal or timber planks)
which also act as bracing
elements, on the vertical frames.
The attachment hooks engage
immediately with the U-section.
8. On the top scaffold level,
insert the rail posts. Attach the
guard rail and toe boards here
as well to give the working plat-
form all-round stability. The
scaffold is tied in accordance
with regulations by using the
scaffold retainers and couplers
which are connected to the
doweled ring screws.

Some scaffolds are incapable of coping
with the projections, recesses, bay windows
and angled surfaces on certain buildings.
BOSTA 100 takes them in its stride. Thanks
to the enlargement brackets which can be
fitted on one or both sides. Available in
three dimensions: 35, 70, and 100 cm, they
widen the working width up to 2.5 m. What’s
more, they are also compatible with the
BOSTA 70 scaffold. And with the 100/200
enlargement bracket, a system offset is
quickly and conveniently fitted.
Everything within reach
Enlargement brackets, the smart solution

BOSTA 100Purely practical
Useful extras for everyday use
The passage frame
Provides a safe passage way for pedestrians
on pavements. Available in widths of 1.00 m
or 1.50 m. The guard rails and diagonals
are fastened to the outside by means of
gravity flips, thus preventing the possibility
of injuries.
Hint
The passage frame 100 can also be used
as an interchangeable frame, meaning that
the BOSTA 70 can be erected on top of
BOSTA 100.
The system bridging girders
With the 5.00 m and 7.50 m system bridge
girders, oriels and driveways are easily over-
come with just a few parts. Two or three
bays are simply bridged. Even large-surface
coverings and/or working areas can be
constructed.
The system-free lattice girders in steel
or aluminum
For spanning and bracing wherever
scaffolds have to be partly suspended. As
these girders are system-free, they can be
attached anywhere independently of any
bay length. Available in 3.10 m to 7.60 m,
in aluminum up to 8.10 m.
The shelter bracket
Crossbar and strut connect with hinges and
are fastened to the vertical frame. With
cantileverages of 1.00 m and 1.80 m, they
serve as a protection against falling objects.
Protection grates for roof tilers
Safety by the rules! The safety grates are
easily mounted and protect men and
material from falling down. They are also a
substitute for the three-part guard system.
Select the BOSTA 100 plank you prefer—all
of them are approved and will absorb
dynamic loads.
The standard BOSTA 100 range also
includes the passage frames, bridges and
protective roof scaffold components suit-
able for heavy loads. System solutions
helping you to save time and money.
12
Something to stair at
Safe solutions for your ups and downs
For all the ascents and
descents in the BOSTA 100
range, the same applies as
throughout the program:
convenient solutions using
only a few parts.
Access any level safely and
easily using the internal ladder
passages directly integrated
with horizontal frames, passage
planks or panels when assem-
bling the scaffold.
Another option is the single-
flight stairway fitted outside the
BOSTA 100. A 2.50 m bay with
flights of stairs and handrails is
built in front of the scaffold.
The stairs are 65 cm wide, the
maximum overall height is
64.50 m. Safety certified. The
necessary vertical frames are
part of the smaller BOSTA 70
program.
13
BOSTA 100A moving experience
Mobile scaffolds for indoors
and out
It takes only a few additional
parts to access completely new
applications. A mobile tower
scaffold reaching up to a height
of 10.50 m indoors and 8.50 m
outdoors.
Depending on requirements, these
mobile scaffolds come with a
variety of widths. With assembly
in the center of the castor wheel
bar or on one side, the working
platform is 1.00 m wide. If two
scaffolds are erected side by side
and joined in the middle by planks,
safe working platforms of 2.50 m x
2.50 m are created.
14
Everything in place
Useful accessories
Smooth and efficient operation
depends on everything being
in place. Planks, frames and
other parts must be stored
neatly, without wasting space,
and professionally. And this is
why BOSTA 100 comes with
the appropriate accessories.
Naturally, all the parts can be
transported by fork lift truck
or crane, all the steel parts are
hot-dip galvanized. And we
also have a number of practi-
cal tools to make everyday
work easier and safer.
The dowel tester
For checking safe dowelings of
the screws/bolts on the building.
Designed so that the pressure
is outside the potential break-
out range of the dowel.
Provides precise and reliable
test results.
Trolley
Scaffold materials weighing up
to 1 t can be stored on a pallet,
and together with two trolleys,
transported.
The scaffolding ratchet
The first ratchet with integrated
torque. For an exact and safe
assembly of the couplers so
that the coupler is tightened and
not overtightened.
Nets and tarpaulins
The nets are made of HDPE-
monofilament yarn, doubly
woven in the center. The tarpau-
lins consist of lattice-reinforced
and UV-stabilized polyethylene.
A reliable protection against
falling materials and dirt.
The Euro lattice box
Transport and storage box in
steel for housing small parts
up to a weight of 1.2 t. Up to 5
boxes can be stacked. The
lattice box can be partitioned
into two, three or four compart-
ments, e.g., for couplers,
enlargement brackets, scaffold
retainers, etc. Combinable with
the Euro stacking frame.
The identification tarpaulin
In certain cases prescribed by
the workmen’s compensation
insurance, the scaffolding can
be lastingly and easily legibly
identified on this tarpaulin.
Secured to the guard rails.
