Thank you for purchasing POLANIK cage type KLD17-5/7-A
Safe assembly and use
•Before you start to assemble and use the cage please read this manual carefully, watch the enclosed instruction
film and store the manual in a safe place for further reference. Polanik Sp. z o. o. shall not be liable for any cage
damages which are the result of the failure to follow this manual.
•Unauthorized copying of this manual, in whole or in part, is prohibited.
•The contents of this manual are subject to change without notice.
•Warning! The sports equipment produced by Polanik Sp. z o. o. is designed for athletics training and use in sports
competitions only. Please pay special attention especially when using throwing implements and other throwing
equipment, misuse of athletics equipment and implements can cause serious injury or in extreme cases even
death. That is why training and use during sports events have to be always supervised by authorized sports
personnel. In no event shall Polanik Sp. z o. o. be liable for any special, incidental, indirect or consequential
damages in connection with the purchase or use of POLANIK products or costs over the original cost of the
product.
•Specific warranty terms:
1) The use of the throwing cage (KLD17-5/7-A) is to be done in the properly marked and secured sports facility
designed for that purpose and under supervision of qualified coaches, and according to: the rules of the
International Association of Athletics Federations (IAAF), respective national athletics federation and local
safety regulations. Failure to follow the above restrictions results in loss of the warranty rights.
2) The throwing cage (KLD17-5/7-A) is designed to protect the spectators against the improperly released discus
which misses the cage mouth. The execution of that task brings a risk of damages to the cage elements (for
example the pillars), as a crumple zone of an automobile is damaged to absorb energy from the impact during
an accident to save passengers. The damages caused by the proper cage operation, which is stopping
improperly thrown discuses from flying outside the cage and absorbing the impact energy in order to protect
the thrower inside the throwing circle, are recognized as a normal wear of the product and are excluded
from the warranty. The damages can be removed in course of payable repair or replacement of the cage
elements.
3) The use of the non-genuine spare parts (not produced by Polanik) results in loss of the warranty rights and
the termination of the IAAF certificate validity.

I. Characteristics of KLD17-5/7-A
The safety cage for discus throwing is a modern construction made of high quality materials. Main characteristic
features of the cage are as follows:
1. Innovative construction:
•Net is hung in such a way that it does not touch the aluminium structure in any point.
•Cage pillars are not linked with each other by means of inflexible elements, that is why they work
independently.
•Application of anchors (instead of popular sockets) eliminates rusting caused by water penetration
in the lower parts of the cage.
2. High durability:
•Cage construction is made of aluminium which is anodized in silver colour.
•All tube ends are protected with caps. They stop water from getting inside the construction and
provide good finish and appearance.
•Steel elements are hot galvanized or electro-galvanized. All ratchet mechanism casings are
additionally coated with powder paint.
3. High quality:
•Cage is an IAAF certified product.
•Cage complies with the IAAF rules 2020.
•Cage is equipped with high quality, certified net.
•Net is strained and fastened at the cage bottom by means of steel cable and hooks. That lets us
eliminate traditional bags filled with send.
4. Easy operating:
•Cage can be assembled and disassembled without using a crane or an extension arm. Assembly (or
disassembly) takes approximately 3 hours done by 3÷4 people.
•Each pillar is equipped with the self-blocking mechanism of lifting and lowering the net by means of
crank.
We deliver the cage to a customer in partially assembled units. Assembly should be conducted according to this
manual. Since the enclosed instructional CD presents the discus and hammer throwing cage with two movable panels,
it should be only used as an general illustration of the installation process.

III. General assembly description
We ship the cage to a customer in partially assembled units. Extension arm with rollers and ratchet mechanism is
already installed in each cage pillar (item 1) (see drawing no. 1, 2 and 5). The cage construction consists of 9 pillars 5 m
high (item 1, drawing no. 1, 2 and 5). Pillars are fastened to anchors (item 2, drawing no. 1 and 2), which are
embedded in concrete according to the plan of the foundation blocks –drawing no. 3. The anchors should be
positioned in concrete in such a way that their hinges and arms face the throwing circle. Installed pillars constitute the
main structure of the cage which is ready for affixing the net and hoisting it.

IV. Anchors –placing in concrete
The installation of the anchors is a key stage to the whole assembly process of the cage and its further proper
functioning, so please pay particular attention and install the anchors with high precision. The anchors are delivered
ready for installation –the screws situated in the upper plates of the anchors are fully screwed down and their threads
are protected by rubber sleeves. If concrete plasters the threads of the screws, it will be impossible to install the
pillars. Before installation please make sure the screws are fully screwed down and the threads are secured with
rubber sleeves.
All the anchors must be positioned in concrete foundation blocks towards inside the cage (throwing circle), according
to the direction lines on the anchors plates (see Draw. no. 4, p. 18). Each anchor must be embedded in the foundation
block in such a way that its upper surface is exactly horizontal (then the pillar is vertical) and flash with the target
surface of the throwing facility (see Drawings no.: 1, 2 and 3; p. 15 and next).
ATTENTION! The anchors should be placed in the concrete of the class B20 (C16/20) quality or
higher. Each time the anchor is put into the foundation the concrete should be mixed, so that it
covers tightly the ribbed bars and there are no air chambers inside. During the concrete setting the
foundations should be moistened (in the first week twice a day, in the second week once a day).
You ought to wait minimum 2 weeks before you proceed with the installation of the pillars.

V. Pillars installation
The installation of pillars (item 1, 2 and 3) on anchors (item 4 and 5) is done as follows:
a)
unpack delivered pillars
b)
remove blocking screws (M
8x16) from the ratchet
mechanisms
c)
loosen steel ropes,
d)
fasten temporarily steel rope
loop to lever of ratchet
mechanisms.

WARNING: failure to follow the sequence of these assembly operations could result in serious
accident or damages to the cage construction.
Next rear pillars (item 1) and central pillars (item 2) should be installed one by one according to the sequence shown
below:
Stage one - position the pillar in the anchor hinges.
Stage two - slide hinge axle (item 6) into the anchor hinges.
Stage three - lift the pillar to vertical position.
Stage four - while one man is supporting the pillar in upright
position, the other person is screwing it to the anchor in the
following sequence:
a) screw down two screws (M 20 x 50) opposite the anchor
hinges,
b) then screw down two remaining screws (M 20 x 50) next to
the anchor hinges,
c) remove hinge axle (item 6).
Before you install extreme pillars (item 3), two side arms (item 11) must be installed on each extreme pillar, one side
arm at the height of ~2,5 m and the other one at the height of ~5,5 m (the heights are marked on each extreme pillar
with blue label bands) see the drawing below. Side arms (item 11) and the extreme pillar arm are to be lined up, and
