Overall dimensions
HANDLOPOL
BR-77s roller doors in standard version are made for individual orders,
within dimensions included in
In Fig. 2 required mounting dimensions indispensable for the correct door selection and execution are shown.
Table 1
Full driveway width Minimum widths of side space required to fix W1min and W2min depending on the motor operator used to drive the door are given below. As a standard, after the door has been fully opened there is one coat section left in the opening clearance, so the drivewey height is about 100 mm smaller (Figure 4).
Optionally, on request it is possible to make the door higher so that the
driveway clearance height be equal to the opening height.
Then the required doorhead height is as appropriate: Table 1
If you order the higher version of the door, state "yes" in the column "full driveway clearance". If not filled in, it indicates the door in standard version. Colour AW 77 aluminum sections are made in standard colours: RAL 5012 (blue); RAL 7040 (grey); RAL 8014 (light brown); RAL 8019 (dark brown); RAL 9010 (white). The case is made in standard colours: RAL 8019 (dark brown) - in the case of coats in colours RAL 8014, RAL 8019; and RAL 9010 (white) - in the case of coats in remaining colours. Optionally, on request upon the prior agreement, the case may be painted in any colour from the RAL palette - state possible requirements concerning the case colour in the notes.Guides as a standard are painted in the door coat colour, on request they may be painted in any colour from the RAL palette. Give the door coat colour in the order. Purpose of the door According to the purpose doors are divided into industrial ones (P) and used in the individual housing (G). Doors to be used in the individual housing are constructed for up to maximum 25 openings daily. If the doors are larger and if you plan more frequent opening, we recommend industrial doors complying to all the industrial building regulations . Write the purpose of the door in the order. Is there an additional entrance The frequency of opening the door is directly influenced by the fact whether the object is provided with an additional entrance or not. Write "yes" or "no" on the order form in the column "is there an additional entrance". Regarding exploitation, it is recommended to provide the garage with an additional entrance. If there is not such an entrance, it is possible to mount a crank with a hook led out outside the room (information on the crank is given on page 6E, on the order form in the column "crank type"). Wall Depending on the execution, BR-77s roller doors may be fixed to the walls made of reinforced concrete (B), brick walls (C) or walls made of steel frames (S). In the order give the exact data of wall execution as well as the wall thickness. The room dedicated to the mounting has to be completely finished (walls plastered, floor finished), the walls cannot have the traces of defects of execution. The room has to be dry and free from chemicals harmful for paint coats. Too much dampness in the object may have a negative impact on the door operation and its durability, and even lead to the door damage. Number of glazed sections Section in glazed version may be used in doors type HANDLOPOL BR-77s in order to light better the room. These section are not provided with heat insulation. Examples of placing section with windows are given in Fig. 5 (versions 1 and 2).
Maximum 6 sections may be used in the door coat in glazed version. For the doors with the dimensions close to maximum ones, it is recommended to use maximum three glazed sections and to fix them as low as possible. It is permissible to fix maximum three sections directly one after another. State the number of glazed sections in the order and show in the enclosed drawing at what height from the garage floor level they are to be fixed in the door coat (example of a drawing illustrating the way of glazed section location marking is given below), if you do not wish glazed sections, put sign "-" in the column.
Electric drive BR-77s roll-up doors as a standard are equipped with an electric drive with a one-phase tubular motor operator, operated manually from the inside of the room and a switch-off for the key fixed outside. The tubular motor operator is not intended for continuous operation. Motor operator construction allows for 40% effective working time counted in the period of 10 min., i.e. this motor operator may be working for about 4 min., then there must be a break in work for about 6 min. Otherwise, a thermal switch comes into operation and the door will be put out of action for a dozen of minutes (till the motor operator is cold). For industrial doors, with the heavy-duty work and in the case of a high frequency of door opening, we offer a three-phase compact motor operator, which ensures door correct function. Write in the order form in the column "motor operator":
Additional equipment of the electric drives may be remote control using transmitters and an automatic door closing. Photocells are installed as a standard in each case of using remote control or automatic closing, protecting from the door closing when there is an obstacle in its clearance. Automatic closing causes that the door is automatically closed after a determined time set in the controller. Write "yes" on the order form in the column "automatic closing" in the case of ordering a control with the automatic closing. Specify the number of additional transmitters (there are two in standard) in the order when you order the remote control. Write on which side of the door, looking from the room inside, the supply source is (left - L or right - P). Information concerning the supply source position determines on which side the motor operator driving the door is to be installed, as the motor operator as a standard is installed on the same side of the door where the supply source is. With the industrial doors it is recommended to apply the light signalling letting to know if the door is open or closed. The signalling device sends green light if the door is open, whereas when the door is closed or in motion the signalling device sends red light. Write "yes" or "no" on the order form. Optionally, on request it is available to install an optical safety bar. If you wish to order the safety bar, state it in the column "NOTES" on the order form. Fixing the case As a standard the case to which the door coat is rolled is fixed inside the room, however, in the exceptional cases it is available to fix it outside (this solution is not recommended). In such a case however, there is a danger of opening the door by unauthorised people, as the access to the door construction is significantly easier. State the place of fixing the case in the order form: inside (W) or outside (Z) the room. If you wish to have the case fixed outside the room, it is indispensable to consult it in advance with HANDLOPOL company. Crank type In the case of the electric control damage or supply voltage cut-off there is a possibility to open the door manually using the device driven with a hand-crank. An emergency drive crank may be permanently fixed at the door case (S), or in the version with a hook (H) put on a handle only when necessary. Determine the crank type in the order. As a standard the crank is fixed inside the garage, but when the garage is not provided with the additional entrance, the crank is fixed outside, in such a case contact each time HANDLOPOL company in order to complete the data. Put the possible additional requirements concerning the door execution on the order form in the column "NOTES".
