Adjustable HALFEN channel mounting systems offer a whole range of benefits:
▪ The adjustable HALFEN channel-bolt system is an assembly and mounting system
▪ Full flexibility in positioning and dimensioning of the bolt connections
▪ Choice of corrosion protection: - Pre-galvanized channels for low demands
- Hot-dip galvanized channels for high demands
- Channels in stainless steel for high-performance requirements
▪ Quick assembly and adjustment of equipment and structural components
With HALFEN mounting channels you avoid:
▪ Time consuming planning of inflexible bolted fixings ▪ Costly manufacturing of bolt fixings▪ Costly corrosion protection work

Introduct ion
Quality is an outstanding feature of our products. HALFEN materials and products are subject to stringent quality controls.
Quality
HALFEN cast-in channels
Certificate-no. QS-281 HH
A quality audit by Germanischer Lloyd Certification GmbH confirmed that our quality management system meet the demands of the ISO 9001:2008 standard.
All hot rolled HALFEN profiles and some of the light framing channels are also available as HTA/HZA HALFEN cast-in channels for embedment into concrete. Both versions use the same T-bolts and locking plates.
You can find more information on HALFEN channels in our catalogue;
" HALFEN Cast-in channels Product Information, BP"
when upgrading already completed structural components i.e. when adjusting components in service
▪ Change or up-date entire projects with standard tools
▪ No specialist required to carry out modifications on-site
▪ Dust free and low noise levels when modification work is done on-site
▪ Corrosion protection is not compromised by bolting▪ A large selection of standard chan-
nels with good load bearing charac-teristics. All the loads stated in this catalogue are permissible loads

HALFEN FRAMING AND MOUNTING SYSTEMS
Mount ing channels
The hot rolling process makes these channels ideally suited to: ▪ heavy loads▪ dynamic loads ▪ connections requiring very high torque ▪ welding
Cold-rolled channelsChannels are available with holes (ladderbacked) or without holes (plain).
Hot rolled channels
Smooth channels HM▪ Very high tensile loads of up to 7.0 Kips (31 kN) are possible▪ High longitudinal loads of up to
1.7 Kips (7.5 kN) are possible using nibbed T-bolts (carbon steel channels)
Cold-rolled channels HL, HM▪ For lower loads in longitudinal channel direction▪ Economic due to large selection of channels
Toothed channels HZM▪ Toothed profile mechanically interlocks
with toothed bolt to allow high longi-tudinal loads of up to 4.9 Kips (22 kN)
▪ 3 channel sizes for maximum efficiency
Toothed channels HZL, HZM▪ For high loads in longitudinal channel direction ▪ Non-slip connection for high channel loads Cantilever fixing on a vertical conveyor system

Locking plates with spring are used in particular for securing plates or panels. (see Medium duty Framing system page 35).
Locking plates (channel nuts) allow any metric bolt or threaded rod to be used. Locking plates for UNC threads are available.

The HALFEN adjustable assembly systems can be used in a wide range of fields. It is therefore important that the codes, guidelines and design criteria applicable to each field are considered. The technical values and data for framing channels and T-bolts for use in the building, mechanical engineering and steel construction industries are explained in the respective sections below.

Fv Bolt pretension forceThe bolt is pretensioned by torquing, and is calculated according to VDI 2230 guidelines
FR Resulting force The resulting force FR is the vector addition of the external loads FL in the longitudinal channel direction and the external load FQ transverse to the longitudinal channel direction; the resulting force is transferred frictionally to the channel.
FSZ Force in the longitudinal bolt direction The force FSZ works as an external load along the screw longitudinal axis and perpendicular to the channel surface and is transfer-red frictionally to the channel.

Cant i levers
Flexible comprehensive support system
Short assembly times
Heavy duty framing system Medium duty framing system Light duty framing system
The flexibility of HALFEN cantilevers and T-bolts makes them ideal when the exact positions and sizes of supports are not finalized at the plann-ing stage of a project. Using the HALFEN product range avoids costly and complex adjustment work, drilling or thread cutting, in components which may already be corrosion protected.
Whether for low or very high perfor-mance requirements, you are guaran-teed to find an effective solution in the HALFEN product range. Using adjustable bolt connections, components can be in-stalled, dismantled, moved and adjusted quickly and simply.

Observe minimum distance ae between channel end and load point (HALFEN bolt, locking plate): heavy and medium duty framing systems: ae ≥ 1 3/16" in, light duty framing systems: ae ≥ ¾" in.
Do not exceed the bolt load capacity or the max. channel load bearing capacity.
For maximum point load capacity: Fz = max. bending load capacity on the channel lips.
Brace channel during installation to prevent possible buckling or twisting when load is applied.

Generat ing the pretens ion force FV
When installing the bolted connection, the tightening torque MA induces a pretension force FV in the bolt, which results in a clamping of the component to the framing channel.
The pretension force FV depends on the tightening torque MA, and the friction coefficient G of the bolt thread and K of the nut contact surface.
The user can determine a pretension force FV individually by referring to the tables above.
The pretension forces for HALFEN T-bolts in steel, strength grade 4.6 and 8.8 and for stainless steel T-bolts A4-50/A4-70 are specified in the follow-ing tables (ref: Rohloff-Matek). The data listed for the tightening torque M
A are recommended values.
Halfen T-bolts are delivered ready for installation, with no lubrication. The
friction coefficients μG and μK are 0.24.

Transfer of static loads
External loads FL, FQ and FSZ acting on the building component are transferred to the bolt connection by clamping.
Force FSZ acts positively in the bolt longitudinal axis.
Force FL acting in and FQ acting transverse to the longitudinal channel direction are transferred through the component-channel surface under friction and are added to the resulting force FR:
To transfer the friction force FR requires a normal force FN acting in the bolt longitudinal axis:
The minimum required clamping force FK erf is a result of the two forces FN and FSZ acting in the bolt longitudinal axis:
The permissible dynamic loads for channel assembly systems are shown as for delivery condition (μG = μK = 0.24) and for lubricated T-bolts (μG = μK = 0.14) in the tables on page 63. The values for FR apply only to transverse force requirements (FSZ = 0), the values for FSZ for pure traction force requirement (FR = 0).
When overlaying the transverse force FR and longitudinal force FSZ apply the formulas listed above for the maximum assembly pretension force FM.
FR = FL2 + FQ

FM max ≤ FV
FM min = SSetz × FK erf
According to VDI guideline 2230; when designing the bolt connection, the bolt tightening procedure and the bolt setting behavior must be considered.Because the setting force loss for adjustable bolt connections is difficult to calculate using VDI 2230, the setting factor SSetz is intended as a safety factor. Therefore the minimum necessary assembly pretension strength is FM min :
Taking the bolt tightening procedure into consideration with the tightening factor αA the maximum necessary assembly pretension force FM max is calculated as:
The maximum required assembly pretension force FM max must be smaller than the pretension force MA produced by the bolt tightening procedure moment FV:
FRFK erf = FN + FSZ = μT + FSZ
FM max = αA × FM min

Transfer of dynamic load
Hot-rolled mounting channels are suitable for the transfer of dynamic loads when used in conjunction with nibbed HALFEN T-bolts (type HSR) or toothed HALFEN T-bolts (type HZS). The dynamic load FL dyn acting on the fixed element in the longitudinal channel direction, is transferred through the channel/bolt contact surface, locked under friction to the channel.
A clamping force FK erf acting in the bolt longitudinal axis is necessary for friction transfer FL dyn:
The calculated maximum assembly pretension force FM max must be less than or equal to the pretension force Fv of the bolt (see table):
The permissible dynamic loads for channel assembly systems are shown as for delivery condition (μG = μK = 0.24) and for a lubricated condition (μG = μK = 0.14) in the following table. The values are valid for pure alternating stress with a transverse force in the longitudinal channel direction.The stress ratio is R = −1 and the maximum number of load cycles is N = 10
