SAFETY
EXPLANATION OF THE SYMBOLS
Caution: To prevent personal injury, you must observe the safety
instructions below.
Note: To prevent material damage, you must observe the safety in-
structions below.
Information:This is followed by further information or by a reference to other
documents.
INTENDED USE
Giving safe access for goods and vehicles accompanied or driven by persons in in-
dustrial, commercial or residential premises.
Carefully read this user manual before operating the gate.
GENERAL SAFETY INSTRUCTIONS
•The operator must read the entire user manual before the gate is used for
the first time. The instructions stated in the user manual must be observed
and complied with. All other forms of use can cause unexpected hazards
and are forbidden.
•Any damage to/defects in the gate that could affect the safety of the user
or of third parties must be repaired immediately.
•Closing the gate infill openings in any way, such as by means of banners,
advertising signs etc, is not allowed as this may negatively affect the safe
operation of the gate.
•All alterations or extensions to the gate must be carried out by qualified
personnel using parts which the manufacturer has defined as suitable for
such alterations or extensions. Any failure to comply with these
instructions will be considered as non-compliant behavior and will
invalidate the manufacturer's guarantee, as a result of which the risk
entirely transfers to the user.
•For a double sliding gate, it is strictly forbidden to remove the central slam
support (mounted on the floor in the opening). This is important for the
stability of the gate when closed.

•Improper usage or servicing or ignoring the operating instructions can be a
source of danger for persons, and/or result in material damage.
•If the meaning of any part of these installation and operating instructions
is not clear, then please contact your supplier before you use the
equipment.
SAFETY PROVISIONS EMPLOYED
To comply with the CE marking, manually operated gates must be designed in ac-
cordance with EN 13241:2003+A2:2016 and EN 12604:2017+A1:2020. Among
other things, these standards specify the safety requirements.
In addition to mechanical requirements, these requirements are mainly:
•Protection against accidental and uncontrolled movements
•The gate leaves must be protected against falling over during normal opera-
tion or if they come in contact with a stationary obstacle.
Uncontrolled movements – for example, due to gusts of wind – can be prevented
by blocking/locking the leaves in a closed and open position.
See the chapter on OPERATION.
•Make sure that the gate leaf is always blocked against unintended movements
caused by gusts of wind. This can result in injury, damage to property or
damage to the product.
Provisions have been applied to prevent gate leaves from falling over or becoming
derailed. These may differ for each gate type.
See the chapter on SAFETY PROVISIONS FOR SLIDING GATES.
Provisions that protect gate leaves against falling over or from becoming derailed
must NEVER be removed. If they are missing or damaged, make sure that they are
replaced as soon as possible. Please contact Heras if this happens.
SAFETY DURING USE
•Prevent children playing with the gate.
PARENTS ARE RESPONSIBLE FOR THEIR CHILDREN 
•The gate must not be operated in windy conditions, wind force ≥9 Beaufort.
The gate leaf can swing in a way that can result in damage to the construc-
tion.

EN – Translation of the original user manual -1.1 | 2022

•The gate must be able to move freely without there being obstacles in the
gate opening passage or anywhere else on the moving trajectory of the gate.
Do not stick any objects through, over or under the gate which might block
the gate.
•The gate running surface must always be free from snow, ice or dirt that
might affect its sliding behaviour. If the running surface is blocked, the gate
will not move at all or will not complete its movement. An irregular running
surface may cause damage to the drive and/or road wheels.
•In certain circumstances, the sun can temporarily distort the gate. When
closing the gate, the leaf is guided to its neutral position. When opening the
gate, the leaf will move around somewhat. This has no adverse consequen-
ces for the construction.
•Climbing the gate is strictly forbidden as people climbing the gate could be
hurt if the gate is started unexpectedly.
SAFETY DURING INSTALLATION, MAINTENANCE AND DISASSEMBLY
•When working on or cleaning the gate, make sure that the gate leaf is
always blocked against unintentional movements.
•The EN 13241 and EN 12604 standards must be taken into consideration
during installation. To achieve a good safety level, both the above standards
and the national regulations must be taken into account in non-EC countries.
The Delta and uGate have highly tensioned cables fitted in the bottom rail.
If these cables are damaged, they can snap with great force. This can lead
to serious injury. Therefore, it is prohibited to drill into or grind these rails.
!! Only people trained by Heras are allowed to disassemble the bottom rail.
If the gate is damaged, always contact the supplier for an inspection.

DESCRIPTION
Sliding gates are fitted with an integrated lock. For the Delta, this is a hook lock
without a door handle. The uGate has a lock with a spring-loaded latch
bolt/deadbolt and a vertical door handle. The Axel uses a swivel.
The lock catcher (Delta and uGate) is mounted on the stop structure and can be
adjusted in height.

SAFETY PROVISIONS FOR SLIDING GATES
Gate leaves must be protected against falling over and becoming derailed.
This is required in order to comply with the CE marking. Never remove these provi-
sions.
PROVISIONS TO PREVENT DELTA FROM FALLING OVER
With the Delta, the gate leaf is protected against falling over by one or two (de-
pending on the model) U-portals. This guide structure is mounted over the gate
leaf. If a bottom or top guide breaks, the U-portal ensures that the leaf cannot fall
over.

PROVISIONS TO PREVENT UGATE FROM FALLING OVER
In the uGate, the gate leaf is protected against falling over by two guide posts on
one side of the leaf. Plastic blocks are screwed into the posts. If both top guides
break, this structure ensures that the leaf cannot fall over.
The plastic blocks must never be adjusted or removed. If the blocks are damaged
or missing, please contact Heras.

PROVISIONS TO PREVENT AXEL FROM FALLING OVER
With the Axel the gate leaf is protected against falling over by the guide column,
guide bracket and running wheels. If the top guide would break, they ensure that
the leaf cannot fall over.
Illustration 7: Principle guide structure Axel
PROVISIONS AGAINST DERAILMENT
It must never be possible for gate leaves to slide out of the guide, causing them to
fall over. This applies when both opening and closing the gate. To prevent this,
these gates are equipped with end stops. End stops should therefore never be re-
moved.
End stops can be mounted on the leaf, such as on the bottom rail, or as a separate
facility, such as rises.

OPERATION
To move the gate, the door handle or front vertical post can be used as a handgrip.
The bar filling of the leaf is not intended to be used as a handgrip. It can become
deformed as a result.
The initial movement requires extra force. This is normal. This force depends on
the type and size of the gate. If the gate continues to move heavily, please contact
the Heras service department.
Before the gate is closed, the closing protection must first be disconnected.
See the chapter on CLOSING PROTECTION.
OPENING/CLOSING A SLIDING GATE
Always open/close the leaf at an appropriate speed.
Hold the leaf firmly when opening/closing it so that any gusts of wind do not
lead to unintended movements. Just before the gate closes fully, the leaf will
be guided through the rise to the middle, which may require extra force.
The amount of force depends on the weather effects such as sun and wind.
Never slam the leaf against the end position at high speed (>0.2 m/s). This
may damage the product.
5.1.1 Unlocking/opening uGate
Illustration 11: uGate lock and keep
Insert the matching key into the cylinder and turn it so that the gate is un-
