Hawke Transit System





Fireproof and watertight transit system HAWKE International


HAWKE transit system was developed for applications with great emphasis on security and protection of cables and is capable of resisting these influences and environments:

• Fire

• Water

• Gas

• Chemicals

• Smoke

• Explosion


• Noise

• Rodents 

The most common HAWKE transit system in telecommunications, military industry, construction of tunnels, construction of shopping centres, nuclear power plants, hydro power plants, chemical industry, pharmaceutical industry and the marine industry.

                         Type HRT


 Round transit frame, which is supplied in

 types 30,40,50,70,100,150 and 200mm.

 It is suitable for usage in round holes,

 where sealing  is done by tightening nuts

 around the perimeter of the head plate.

 The metallic head and rear plates at the

 same time pull and push the middle black

 rubber ring, thus sealing the assembly

 hole in the wall. At the same time, the

 cable modules are pushed to the centre of

 the passage and thus to overall sealing of

 the entire cable passage.


       Type HMX

 Type: HMX

 The steel ring of the cable passage for the version for welding to the wall or

 passage. This type of frame is suitable for applications such as containers,

 steel constructions, marine industry, tanks, etc. Assembly is done by installation

 of the largest cable sizes and appropriate modules, such that we start from the

 lower modules upwards. Between each module layer, a spacing plate is

 installed to facilitate error-free installation during the pushing process. Naturally,

 each layer must be fitted with the same outer module diameter so that

 assembly can be done. At the end, the compression wedge that seals the

 passage is fitted.








        Type HCX

 Type: HCX

 This type of frame is intended for wall up or bolting. These passages are the

 most common and are intended mainly for the building industry and

 telecommunications. The standard design is steel; upon request stainless

 steel frames are supplied. The assembly procedure for the interior is the same

 as applies to type HMX; the frame as such can be walled up or bolted. In the

 case of this frame, it is necessary to apply intumescent  mastic between the

 wall and the frame so that we eliminate eventual  unevenness between the two

 surfaces and prevent eventual penetration of water or humidity.







                     Fixed frame


 This type of frame is suitable for installation of new cables or ducts.

















                   Divided frame


 This type of divided frame can be used for already existing cable installations, or

 ducts for additional sealing of the passages without any necessity to remove

 already installed cables.















      Multiple frame                  


 For installation of more demanding cable passages with a larger number of

 cables, or necessity to separate certain cable bunches, it is possible to use

 multiple frames.















               Cable modules

 For the inner space of the frame and cable

 installations, typical module series are

 used whereby each module offers a range

 of 3mm for the cable size. Both halves of

 the module are colour-coded for better

 visual check.


Blinding module

 If in the design of cable passages and, eventually, reserves for planned future

 cables, you need to fill a place in the passage, we use sealing modules, which

 are in the same type series as the cable modules. Again, it must have the same

 outer dimensions as the cable modules.








               Compression system

 For installation of type HMX A HCX frames, we need a compression system. The

 compression system can be collapsed into 3 components, such that it is easy

 to insert two outer parts of the compression system into the compressed

 installed module with an compression tool, after which the compression tool is

 released and the third, middle part of the compression system is inserted. After

 this, the 3 nuts on the compression system are tightened and perfectly press all

 the installed modules, thus sealing the cable transit. 






                Compression Tool 

 For error-free assembly of the transit, it is essential before installation of the

 modules to slide out the last layer of the frame with the pressure plate of the

 compression system, install the rest of the modules (at this stage, the limiting

 plate is no longer used) and the assembly wedge is fitted at the centre, which

 upon tightening acts as a jack. We compress the modules of the frame in such

 a way that it is possible to insert the two side parts of the compression system

 along the sides of the assembly wedge.






Pulling Device

 In case of dismounting of the HMX and HCX frame, it is necessary to use a

 pulling element, which acts as a puller. Without this puller, it is not possible to

 remove the centre piece of the compression system, even when you loosen the

 nuts. It is only after removing the centre piece of the compression system using

 this puller, that you can slide the compression tool into the created gap, you

 press the modules in such a way that it is possible to also remove both side

 pieces of the compression system and then release the compression tool  and

 remove it from the frame. After this, you can easily make adjustments without

 any problem.





 The stayplate is inserted between each module layer, excluding the top layer.

 The function of the plate is important, because it ensures proper pushing of the

 modules over the entire width of the layer and the transit is thus perfectly sealed.










Lubrication gel

 Lubrication gel is an important and essential component of the cable.transit. it is

 necessary to lubricate all the inner parts of the frame and modules used in

 assembly because this guarantees faultless positioning of all assembly

 components of the passage and hence perfect sealing of all the transiting

 cables or ducts.








   Intumescent Mastic              

 Intumescent mastic is used in the assembly of the HCX. frame The caused is

 applied between the wall and the border of the frame, thus leading to sealing of

 any eventual gaps (caused by wall surface unevenness) between the frame and

 the wall and thus prevents eventual penetration of water or humidity into the
