SECTIONAL INDUSTRIAL OVERHEAD DOORS WITH INSULATION
SPECIFICATIONS
The door consists of a side system of guides that have a
special
block at
the end of which there is aluminium profile with double
brushes for full sealing. For the movement of the door
idlers a specially configured driver is firmly connected
at the sheathing of this guide. With the approval of the
customer and taking into consideration his needs, the
bottom part of the special driver can be further
processed so as to follow the highest point of the
building and fit perfectly to the internal geometry of
the building leading to a complete ergonomic result
without any noticeable change in the total cost.
The corresponding part of the lifting system is
screwed
at the top of the driver. The entire device is
self-supported.
LIFTINGSYSTEM
The
lifting system consists of a single driver axis that
gives movement to special barrel rings. A strong lifting
belt is wrapped in the sides of the barrel rings.
A
special electric brake motor – reducer of industrial
standards is transmitting the motion to the shaft via
chain sprocket and chain pulleys.
The
rotation of the shaft and the lowering of the door are
protected by a centrifugal accelerator which is
considered the most reliable solution.
The
industrial board has electrical control system for
monitoring asymmetry and succession phases during the
motion. The control is achieved with the use of button
or key-switcher while there is possibility to easily
connect remote receiver and photocells. The controls
buttons operate with low voltage 24 V for safety of
personnel.
PANELSYSTEMS
The panels consist of sheet metal 0,60 mm and are filled
with polyester
which is
welded with special polyurethane glue of 55 kgr/m3
density. They bear specific joints along their edges as
well as special longitudinal reinforcement with
additional sheet where the hingesare
screwed.
At the
edges of the panels special parts are fitted for the
covering of polyurethane. In order to reinforce the
joints along and between fasteners special reinforced
foamy rubber seal is inserted.
The panel at the bottom bears a special rubber groove
which at the edges has specific suspension points
with incorporated protection system in case of fall and
automatic locking system, patent of our company.
The panel located in the upper section of the door is
carrying a special rubber seal.
WINDOW SYSTEMS
It consists of aluminium frame, connected with special
joints so that they formed a single panel whose edges are
identical to the other panels and fully consistent with the
construction creating thus a large visible part. The fitting
of the window with the other parts is excellent with full
sealing.
ADVANTAGES OF THE DEVICE DESCRIBED ABOVE
OVER THE ONES AVAILABLE IN MARKET
1) The
structure is entirely composed of industrial materials with
high standards. It is self-supported and suitable for
industrial use.
2) The motion is transmitted through a driving belt and not
with cables.
So we have:
·
High resistance to loads, six times of the corresponding
devices with cables.
·
Zero wear,
unlimited lifetime.
3) We do not use springs that are perishable and dangerous
with respect to the safety of staff and the numerous
problems that can be created.
4)
It is the only device with automatic locking unlike the
existing competition, where the locking is done manually
with a bolt.
5) The uncontrollable fall of the door is prevented firstly
by the use of centrifugal accelerator at the driving shaft
and secondly by using special automatic locking mechanisms
located at both ends of the bottom door panels.
6)
The manual operation is achieved with a system of chains –
chain hoist, which reaches the height of the hands of the
operator. The system has the ability to be removed for
security reasons.
NEW TYPE PASS-DOOR INCORPORATED IN THE SECTIONAL OVERHEAD
DOOR
TECHNICAL SPECIFICATIONS
The casket and the jamb of the pass-door consist of aluminum
profiles. The opening, closing and locking of the pass-door
is identical to that of a common type heavy duty aluminum
doors with all the necessary rubber sealing. In this case a
hydraulic mechanism of automatic closing of the pass-door is
mandatory. The opening and closing of the pass-door is
achieved with 8 hinges located on the aluminum profiles of
the door. The surface of the pass-door is divided into
horizontal sections like the sectional door. For this
purpose the aluminum profiles are separated by special
high-strength plastic blocks, so that they interlock when
the door is completely closed.
This reinforces the rigidity
of the
pass-door.
The pass-door also follows the movements and divisions that
are formed from the panels of the sectional door.
INDUSTRIAL MANUALLY OPERATED SYSTEM WITH CHAIN – CHAIN HOIST
TYPE
TECHNICAL
SPECIFICATIONS
The manual operation is achieved through a
worm chain where a
system of pulleys-chain hoist- rotates. This system is
operating automatically when the chain is pulled and moves
the roller shutter while at the same time every electrical
activity is stopped. The system automatically reverts to
electric mode when we simply let the chain and the indicator
is lighted. Maximum capacity of elevation 5 tones. The
transmission of motion is vertical.
