Mammut 350
Assembly and Operating Instructions
Product features
The accessories are the same as for Mammut. Mammut 350 is a
crane-dependent frame formwork system and ideally suited for
use in industrial and civil engineering as well as administration and
housing projcets that have a demand for a visible concrete surface.
Mammut 350 features panels with heights of 350, 300, 250 and
125 cm. A complete formwork set including accessories weighs
approx. 62 kg/m². The admissible fresh concrete pressure is
100 kN/m² if tie rods DW 20 are used (required for a panel width of
100 cm or more).
The high admissible fresh concrete pressure results in short concreting cycles since walls up to 400 cm can be poured without taking
the pouring rate into account.
Abbreviations, measurements, figures and tables
The abbreviation M 350 is used for the Mammut 350 system series
and the abbreviation M for the Mammut system series.
DIN means Deutsche Industrie-Norm (German Industrial Standard).
E DIN (E = Entwurf / draft) means that the DIN is in draft status
and not yet approved of. Any further abbreviations are explained
where they are used the first time.
TÜV means Technischer Überwachungsverein. This is the independent German organisation that tests the safety of technical installations, machinery and motor vehicles. If a product passes the test, it
is permitted to carry the GS seal. GS stands for Geprüfte Sicherheit
(approved safety).
Measurements: These instructions use the metric system and thus
m (for metre), cm (for centimetre) and mm (for millimetre). Dimensions without a measure are in cm.
The page numbers in these instructions start with M350. The figures and tables are numbered per page. Depending on its product
abbreviation, a cross reference in the text refers to a page, table or
figure in these instructions or in other instructions
The panels have a 20 mm all-plastic forming face made of polypropylene and aluminium, it is riveted to the panel on the concreting
side. Inside the frame the facing is protected with silicone.

The large-size panels
350/250 (Fig. 5.1) and
300/250 (Fig. 5.2) are
ideally suited for vertical
and horizontal use. Since
the tie holes are located
inside, the 8.75 m² facing of the 350/250 panel
requires only 6 ties and
the 7.50 m² facing of the
300/250 panel requires
only 4 ties.
Panels can be connected
to existing walls without alignment rails and
additional panels or
fillers. The panel can
overlap up to 50 cm (see
p. M350-27).
If 250 cm high panels are
extended horizontally
on top of each other, an
even joint pattern with
uninterrupted vertical
joints can be assured.
m350ava-gb.pdf St. 10/12/08 Printed in Germany

Vertical and horizontal
panels can be combined
freely. Each panel joint
requires 3 assembly locks
for a panel height of
350 cm, or 2 assembly
locks for a panel height
of up to 300 cm.
Panels with a width
of 125 and 250 cm are
equipped with 4 bump
notches that are diagonnally welded in. An

alkus plastic sheet
The polypropylene and
aluminium composite
forming face has all the
positive properties of
plywood plus important
advantages: longer
lifespan, greater loadbearing capacity, better nail-holding ability,
fewer and easier repairs,
100 % recyclability.
Besides the obvious
advantages, such as
considerably reduced
cleaning effort, minimum consumption of
release agent and an
excellent concrete finish,
alkus offers substantial
ecological benefits.
Substituting plastic for
wood saves valuable timber resources. Also, further releasing of highly
toxic dioxin is avoided,
which is released in
the process of burning
plywood (that is bonded
with phenolic resin).

Panel connection
Its 5-point contact
(Fig. 7.2. and 7.3) does
not only draw the panels
together, it also aligns
them. With only a few
hammer blows a safe
connection and a perfect
alignment are achieved.
Since the lock weighs
only 3 kg, it can easily be
attached with only one
hand.
Panels with a height of
350 cm are connected
with 3 assembly locks.
All other panels, no matter if vertical or horizontal, are connected with 2
assembly locks.

can be attached on the
frame at any position.
Tie holes
Note
When assembling two
M 350 panels with
different widths, the
ties should always be
placed through the
panel with the larger
width (Fig. 8.3). Always
use all tie holes, i.e. all
usable tie holes must be
used for tieing and non
usable tie holes closed
with plug D27/30.

Recommendation for
concrete placing
For walls higher than
4.00 m observe the
values in tables 9.2 when
using tie rod DW 15,
or the values in table
9.3 when using tie rod
DW 20.
According to DIN 4235,
concrete should be placed
in layers, the thickness of
which can vary from 0.50
to 1.00 m.
Concrete must not
be placed from heights
at free fall (1.50 m or
higher).
When vibrating the
concrete, which is done
layer by layer, the vibrator must not penetrate
more than 0.50 m into
the layer below.
A final vibrating over
the overall concrete
height is not recommended. It does not provide any advantage since
concrete that has been
vibrated once cannot be
compacted further. This
may result in water bubbles (shrinkage cavities)
on the concrete surface.

Scaffolding bracket
The scaffolding bracket
90 or 125 (Fig. 15.2) is
mounted to a multi-function profile. To insert the
bracket, turn it by 45°,
then turn it back to vertical position and secure
it with a flange screw
18. Then planks can be
bolted to the brackets.
The max. bracket spacing for an admissible
load of 150 kg/m² (scaffold group 2) is 2.50 m,
depending on the type
of planks and in line with
DIN 4420. The minimum
plank thickness is 4.5 cm.
Guard-railing post

Crane hook
The admissible load
of an M crane hook
(Fig. 16.1) is 15 kN
(1.5 tons).
The handling is easy:
1. Open the safety
lever as far as possible
(Fig. 16.3).
2. Push the crane hook
over the panel profile
until the claw engages
completely in the
groove.
3. Let go of the safety
lever and it will go back
to its start position and
lock the crane hook
(Fig. 16.4).
When moving gangs,
make sure each crane
hook is attached at a
panel joint (Fig. 16.5).
This avoids displacement
of the crane hook. Also
make sure to always use
2 crane hooks and attach
them symmetrically to
the centre of gravity.
Safety check
Always check the crane
hook before use. Do not
overload the crane hook.
Overloading causes damage. A damaged crane
hook is not capable of
full load and its safe use
can no longer be guaranteed.
When to replace
the crane hook
If the reference dimension exceeds 61 mm,
the crane hook must be
replaced immediately.
Replace it also if only
one side of the hook
exceeds this dimension
(Fig. 16.2).
Safety regulations
When using our products, the federal, state
and local codes and
regulations must be
observed. Also observe
the operating instructions delivered with the
crane hook.
Reference dimension must be ≤ 61 mm
Fig. 16.1
Fig. 16.2

Max 60°
When moving single
horizontal panels, both
crane hooks must be

of gravity over the cross
stiffeners of the profile
(Fig. 16.6).

M stripping corner
The M strippping corners
350 (Fig. 22.1), 300, 250
and 125 allow gangs
for elevator shafts and
core walls to be set and
stripped without disassembling the gangs. The
stripping corners work
according to the “jumping jack” principle.
C
The corner is designed
with 3 pieces to permit
inward movement when
the bell-crank lever is
pushed upwards.
D
After removing the
integrated wedge,
the bell-crank lever is
pushed upwards with
a crowbar at position
A (Fig. 22.2 A) or at
position B (Fig. 22.3 B).
This breaks the bond
between formwork facing and concrete without much effort.
Fig. 22.2 A
Fig. 22.3 B
B
The stripping corner can
be reset for the next
pour by positioning the
crowbar at the top and
pushing the bell-crank
lever down. After that
the wedge can be put
back into its starting
position with a few hammer blows (Fig. 22.5 C).

Formwork assembly and stripping
Planning
If you want to benefit
fully from the efficient
and economical use that
the M 350 formwork
offers, we recommend
you first plan and
prepare its use. Start
planning by determining
the optimum formwork
quantity to be held in
stock (such quantity is
usually based on the
amount of formwork
required for a one day‘s
work). When determining the quantity, consider this:
„ the formwork weight
„ the time required for
formwork assembly and
stripping
„ transport of gangs
from one pour to the
next considerably reduces
forming time
„ capacity of the lifting
devices
„ a logical cycle plan that
takes corner configurations, reinforcements etc.
into account
Once all these aspects
have been considered,
the quantities of formwork items can be
specified.
Ground
The ground on which
the formwork is going
to be placed should be
clean, even and capabable of bearing the
expected load because
this will help reduce the
time required for the
assembly and stripping.
Panel transport
When unloading panels
or moving panel stacks
make sure you use
appropriate transport
devices that can bear the
load. For detailed information see p. M350-46
through M350-49.
The steps required for
the assembly
For ergonomic reasons,
the outside formwork is
ususally assembled and
placed first. Start the
assembly in a corner or
at a determined point
and perform the following steps:
Fig. 42.1 Double-sided formwork
Step 1 – Place and brace
the outside formwork
Step 2 – Define and
mark the concreting
height, build in the reinforcements and boxouts
Step 3 – Place the inside
formwork and tie the
outside and inside formwork
Refer to the following
pages for a detailed
description of these
steps including the
working platform and
formwork stripping.

1. Spray the facing
with the release agent
MevaTrenn FT8.
2. Place the first panel
and immediately attach
it with two brace frames
to the ground to prevent it from falling over
(Fig. 43.1). Attach the
foot plates firmly to the
ground, with two soil
nails when attached
directly to the soil or
with two heavy-duty
dowels when attached
to a concrete foundation.
m350ava-gb.pdf St. 10/12/08 Printed in Germany
Fig. 43.2
Filler for easy stripping
After placing panels,
always reinforce them
immediately with pushpull props or brace
frames so they withstand
tensile force and pressure and are protected
against displacement
and wind. The push-pull
prop spacing depends
on the application.
If the scaffolding bracket
was not preassembled
before step 1, you can
now assemble the working platform and attach
it. Fig. 44.2 on page
M350-44 shows a working platform being lifted
with a crane for attachment at a braced outside
formwork.
3. String further panels
together and connect
them with M assembly
locks (see p. M3507).
Panels with a height of
350 cm are usually connected with 3 assembly
locks. However, outside
corner configurations
require 4 assembly locks
(Fig. 43.2 and 43.3).
Step 2 – Concreting
height, reinforcements and boxouts
Following step 1, the
concreting height is
defined and marked,
the reinforcements and
boxouts, if required, are
installed.
Step 3 – Place the
inside formwork and
tie the outside and
inside formwork
The inside formwork is
placed after the outside
formwork. Then the
inside and outside formwork are tied firmly with
tie rods and articulated
flange nuts.

Step 1 – Place and
brace the outside
formwork
The following description is based on an even
wall. Before starting,
keep in mind:
„ When preassembling large panel units on
an even surface, attach
the wall braces and the
scaffolding bracket as
well, i.e. before executing step 1.
„ Walls of less than 6 m
require a filler for easy
stripping (Fig. 43.3) as
otherwise the formwork
may wedge when stripping and stick to the
concrete.
Working scaffold
The plug-in scaffolding
bracket (Fig. 44.1) is the
basis for the working
scaffold. The maximum
bracket spacing for a
load of 150 kg/m² (platform group 2) is 2.50 m
as defined in DIN 4420.
The planking must at
least be 4.5 cm thick.
The planking and scaffolding bracket can be
firmly connected. Do not
place any planks before
having secured the
formwork with push-pull
props or before having
tied the inside and the
outside formwork.
Do not forget to attach
a side railing to the
working scaffold if such
a protection is required.

of placing, taking the
temperature and cement
type into account (see p.

3. Loosen the formwork
panels or large panel
units by removing the
assembly locks at the
panel joints and remove
them manually or with
a crane. Before removing them with a crane,
make sure the formwork
is detached from the

4. Clean the facing
and remove any concrete. Before the next
use, spray the facing
with the release agent
MevaTrenn FT8 (for
alkus). Observe the operating instructions for the

When stripping manually, detach and disassemble the working
scaffold and the brace
frames before stripping
the panels.
When transporting large
panel units with a crane,
the working scaffold
and wall braces are not
detached from the panel
units. While in vertical
position, all components
are cleaned and sprayed
before being transported together to the
next site of use (see p.
M35037 and M350-38).
If there is no further use
for the panel units, the
working scaffold and
wall braces are detached
and disassembled in
horizontal position,
cleaned and stacked for
transport.

Stripping
Do not start stripping
before the concrete has
set to the point where it
cannot deform anymore.
It is best to start stripping at the stop ends
or at a corner. Walls of
less than 6 m require a
filler for easy stripping
at the inside formwork
(Fig. 43.3 on page
M350-43) as otherwise
the formwork may
wedge and stick to the
concrete. Start stripping
with the inside formwork. Stripping of both
the outside and inside
formwork is done as
follows:
Crane slings Stapos 60
These crane slings are
made of polyester tape
with double-sided textile
coating. The load-bearing capacity is stamped
on the coating. The sling
is provided with a galvanized self-locking fastening device (Fig. 46.1).
Handling
1. Place the panel stack
on square timbers of
10 cm (Fig. 46.2).
2. Push the suspension device under the
stack with your foot
(Fig. 46.3).
3. Yank the sling up
(Fig. 46.5). The elastic fastening pin will
engage completely
in the profile groove
and secure the stack
against accidental uplift
(Fig. 46.4).

Attention
A lifting hook must only
be used if its eccentric is
easy to turn or automatically falls into the locked
position (Fig. 48.2). Never
use a lifting hook if you
need force to turn its
eccentric. Turning the
eccentric with force may
not the lock the lifting
hook but only make
it appear to be in the
locked position. This may
cause the lifting hook to
slip off its position when
lifting the panel stack.
App
The crane slings
(Fig. 48.1) help to quickly
load and unload trucks
and move the Mammut
350 panel stacks near
the ground. The lifting
hooks are inserted into
the welded sleeves of
the bottom panel frame
(Fig. 48.3). After tightening the crane slings
check to make sure the
hooks are safely locked
(Fig. 48.2).

Moving panel stacks
When moving panel
stacks, make sure panels are secured against
slipping. MEVA secures
them with safety bolts
and, for truck transport,
also with load/cargo
straps (see p. M350-50).

M35049
M350
The lifting hook
(Fig. 49.1 and 49.2) can
be used with any fourrope crane device on
the construction site to
transport panel stacks.
Always use 4 hooks
together. To calculate
the admissible loadbearing capacity, assume
only 2 hooks.
Transport
Make sure that all material is secured properly.
Recommendation
Use one load/cargo strap
per 1 metre of cargo
(Fig. 50.1). That means
for a fully loaded truck
with a trailer length
of 13.60 m, 14 load or
cargo straps would be
required.
M 350 panels require
2 or 3 straps. Due to
their low weight, M 350
corners require only 2
straps.
Fig. 50.1
When moving panel
stacks make sure that
panels are secured.
MEVA secures M 350/250
panels with the grey
M 350/250 safety bolt
(Fig. 50.2) and all other
M 350 panels with the
black M safety bolt.
These plugs should also
be used by the job-site
when returning material.
Safety regulations
When using or transporting our products,
the federal, state, and
local codes and regulations must be observed.

Service
Regeneration
The regeneration is carried out as follows: The
frames are checked and,
if necessary, repaired,
painted and provided
with a new facing.
As long as the formwork
equipment is up-todate, a regeneration
will always be a more
economical solution
than purchasing new
formwork.
Please note that the
cleaning and regeneration service is not available in all countries
in which MEVA does
business.
Formwork drawings
Of course, all offices
in our technical
department have CAD
facilities. You get expert,
clearly represented
plans and work cycle
drawings.
MBS
MEVA Basic Support
MBS is an addition to
AutoCAD, developed
by MEVA Formwork
Systems in 2000. MBS
is based on standard
programs (AutoCAD and
Excel) and can be used
on any PC that has these
two programs installed.
It includes pull down
menues for AutoCAD
and applications to ease
forming. It also includes
the possibility to create
takeoffs.
Special solutions
We can help with special
parts, custom-designed
for your project, as
a supplement to our
formwork systems.
Static calculations
Generally, this is only
necessary for applications like singlesided
formwork where the
anchor parts are embedded in the foundation or
the base slab. If requested, we can perform
static calculations for
such applications at an
additional charge.
Formwork seminars
To make sure that all
our products are used
properly and efficiently,
we offer formwork
seminars. They provide
our customers a good
opportunity to keep
themselves up-to-date
and to benefit from
the know-how of our
engineers.
m350ava-gb.pdf St. 10/12/08 Printed in Germany
Rentals
With much equipment
on stock, we offer our
customers the option of
renting supplementary
material during peak
times. We also give
prospective customers
the chance to test MEVA
formwork so they can
see its benefits for
themselves in actual use.
