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!

BOSTA 100

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

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

11

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.
