 JENKA System
1. General Information
The Peikko JENKA anchor is a component of the
Peikko transport anchor system and is in compliance
with the safety regulations set forth by the (German)
Construction Trade Association “Sicherheitsregeln für
Transportanker und -systeme von Betonfertigteilen”
(BGR 106).
Compliance with this installation and operation manual
is necessary for the use of Peikko JENKA anchors. The
anchors are only designed to operate with original Peikko
Lifting Devices. All existing installation and usage manu-
als must also be considered.
The Peikko JENKA System is designed for the transport
of precast concrete construction components. Compo-
nents should not see repeated operation. Construction
components (specifically the transport anchor) may
undergo some erosion during the transport of a com-
ponent from the place of production to the place of
installation, however this is not considered as repeated
operation. Repeated operation is for example, the use of
precast concrete components as a removable dam, or
as counterweight of a crane; this is only permissible if
warranted by the type approvals “Erzeugnisse, Verbind-
ungsmittel und Bauteile aus nichtrostenden Stählen”
(“Products, Connections, and Construction Components
of Stainless Steel”) (DiBT Berlin, Zulassung Nr Z30.3-6). Figure 1:

2.4 Reinforcement

2.4.1 Minimum Reinforcement

Concrete elements must have a minimum reinforcement according to tables 13 and 14. These can be substituted with
steel bars of the same diameter. Should it be necessary to remove individual bars for the installation of the anchor, the
bars must later be replaced by bars of the same diameter and reinforcement length. The reinforcement in the concrete
can be taken into account (Reinforcing steel mesh, stirrups, iron bars, etc). Minimum reinforcement is not necessary
with Peikko JENKA BSA anchors. Transport load of the component shall be calculated according to General Installation
Instructions.

2.4.2 Reinforcement for Angular Pull

In the case of loads in angular pull, a reinforcement
stirrup must be applied with pressure contact at the
angular point counteracting the direction of pull (table 15
and figure 7). In case of a max. angular pull of 30° it is
possible to adjust the reinforcement stirrup in length and
diameter. Figure 8: Arrangement of the reinforcement for angular pull

 JENKA System
2.4.3 Reinforcement for Lateral Pull
A load in lateral pull with γ ≥ 15º requires an additional
reinforcement to be incorporated following table 16 in
the face counteracting the direction of pull (figure 11).
Loads in lateral pull (with the use of chain overhead
conveyors) requires no further measures, as the stirrup
provides for this load as well. During lowering and rais-
ing of the component, the direction of the reinforcement
should always be checked (figure 11). Lateral lifting is
allowed only for components with minimum thickness
“d” according to table 9.
Attention: for Peikko JENKA anchor types BSA, PSA,
and WAS, lateral pull is not permissible.

2.5 Corrosion
Lifetime of installed Peikko JENKA Anchors is limited
due to corrosion. Even through the use of electric zinc
plated anchors, corrosion damage can occur and cause
rust damage to the component surface. Corrosion dam-
age can be avoided if after final placement the anchor is
covered with mortar and sufficient concrete covering. If
Lateral-Angular Pull
the JENKA anchor is to be consistently used in outdoor
environments, Industrial environments, or in the vicinity
of sea, we recommend the use of Peikko JENKA an-
chors made of stainless steel. Electric zinc plated Peikko
JENKA anchors should only be stored for a longer time
in dry environmental. To protect the anchors against rust
we recommend to use JENKA CPP plastic plugs.

3.2 Usage
Labeling
All Peikko JENKA TLL wire rope lifting loops are fitted TLL20 2000kg
with a load capacity tag (figure 12). The tag includes the
manufacturer, the load capacity, and the type, much like
the CE labelling. Additionally the load capacity tags are
colour coded, this makes identification of which JENKA
anchor and JENKA TLL wire rope lifting loop to use in
combination both quick and easy.

 JENKA System
Usage
Prior to use of the Peikko JENKA TLL wire rope lifting
loop the intended use of the system component must
be reviewed for safety, the Peikko identification tags
makes this easier. The Peikko JENKA TLL wire rope
lifting loop can only be used with JENKA anchors. The Allowed
JENKA TLL can be used multiple times. Improperly
used, corroded, or otherwise damaged Peikko JENKA
components should not be installed or see further use. Not Allowed
Alterations or welding of JENKA components is not
allowed.
The Peikko JENKA TLL is to be fully screwed into the
JENKA anchor so that the threaded end is inside the
socket of the anchor. The JENKA anchors are designed
so that the JENKA TLL threads can always be complete-
ly screwed into the anchor. Incompletely screwed lifting
loops can not bear load.
The following points must be reviewed during installa-
tion: Figure 14: Case of Operation Straight Pull

• Unclean threads must be cleaned

Allowed
• Visual inspection of the JENKA TLL must be estab-
lished
• Concrete maturity must be verified according to ac-
cident prevention regulations (BGR 500, BGR 151,
BGI 556). Not Allowed

• Thread must be completely screwed into the

anchor.
• Hook size, form, and curvature radius R of the hook
must be checked (minimum of 2 times the cable
diameter, see figure 13)
• Only axial or angular pull of up to 45º is permitted.
• Peikko JENKA components should not come in
contact with acids or alkali.
• Method of safe & unsafe operation are shown in
figures 14 & 15

3.3 Safety Considerations

All load suspension components must undergo a routine
yearly inspection (BGR 500, chapter 2.8). The inspection
is the responsibility of the user and must be done by
qualified persons.
In general the up to date accident prevention regulations
apply. By using the correct size and form of hook, the
durability of a Peikko JENKA TLL can be extended. To
maintain the security of the JENKA TLL, any modifica-
tions (ex. recutting of the threads) is not permissible.
In case of particular occurrences (ex. Loss Occurrence)
the JENKA TLL wire rope lifting loop must undergo an
additional inspection (BGR 500, Chapter 2.8 section
3.15.3). An exact product durability is not established
and depends upon the products use and the regulations
of standards BGR 500 and DIN 13155 or other country

4.2 Usage
Labelling
All Peikko JENKA Lifters are imprinted with a perma-
nent marking on its ring (figure 16). This includes the
manufacturer, the load capacity, and the type, much like
the CE labelling. Finding compatible Peikko anchors and
Lifters is possible through these markings.
Usage
The installation of the Peikko JENKA Lifter must take
into consideration the General Information for Installa-
tion of Peikko transport anchors, this brochure, and the
usage manual for Peikko JENKA anchors. Prior to use
the intended allocation and use of the system compo-
nent must be reviewed. The load suspension devices
of the Peikko JENKA System (JENKA TLL and JENKA
Lifter) are only designed to operate with the Peikko
JENKA anchor. The JENKA load suspension devices can
undergo multiple loads from the place of casting to the Figure 16: JENKA Lifter Identification
place of installation. Improperly used, corroded, or oth-
erwise damaged Peikko JENKA components should not
be installed or see further use. Alterations or welding of
JENKA components is not allowed.
The following points must be reviewed during installa-
tion.
• Unclean threads must be cleaned
• Visual inspection of the JENKA JL must be estab-
lished.
• Concrete maturity must be verified according to ac-
cident prevention regulations (BGR 500, BGI 556).
• Thread is completely screwed into the anchor.
• Appropriate lifting components (hook size and hook
form) is used.
• Peikko JENKA components should not come in
contact with acids or lye.
• The Peikko JENKA Lifter should only undergo loads Figure 17: JENKA Lifter Installation for Axial and Angular Pull
from the directions shown in figures 17 - 18, loads
as shown in figures 19 - 21 are impermissible.

4.3 Safety Considerations

Not Allowed
All load suspension components must undergo a routine
yearly inspection (BGR 500, chapter 2.8). At least every
three years a magnetic break inspection must be made.
The inspection is the responsibility of the company and
must be done by qualified persons.
In general the up to date accident prevention regulations
apply. By using the correct size and form of hook, the
durability of a Peikko JENKA Lifter can be extended. To
maintain the security of the JENKA Lifter, any alterations
(ex. recutting of the threads, straightening the ring head)
is not permissible. In case of particular occurrences (ex.
Loss Occurrence) the JENKA Lifter must undergo an ad-
ditional inspection (BGR 500, Chapter 2.8 section 3.15.3).
An exact product life is not defined, rather is dependant
on the regulations set by the standards BGR500 and DIN
EN 13155 or other country-specific regulations.
