Heavy Ty-Back (HTBH-A) hangers are used to support exterior formwork on bridge decks. HTBH-A hangers are specially designed to react lateral forces prevalent in fascia overhang formwork.The HTBH-A hanger is fabricated to use 13mm or

20mm (2`212`2" or 4b434b4") fasteners which is based on load capacity.

Typically 45º end clips are welded to one end of the hanger and

90º ty-back end clip to the other end. For improved stability of

the overhang formwork, a 90º SUPPLEMENTAL HANGER which allows a 13mm (2`212`2") vertical tie (SWL1000 lb) to be added to th e main hanger next to the 45º end clip on request. Angle Hanger HFR-A is manufactured with a 13mm (2`212`2") dia.

45° end clip and 13mm (2`212`2") dia. 90° end clip welded at eac

h end of the wire strut and is used to support fascia overhang formwork.

*Available in Plain Steel (B), Electro Plated (EP) and Hot Dip Galvanized (HDG) Consult with AR Technical Department for Hanger Length Less than 175mm (7") NB. When hangers are used on concrete beams, the safe working load shown is based on a minimum concrete ange thickness of 5" and beams made with normal weight concrete having reached a minimum compressive strength of 5,000 psi. For hangers used on concrete beams with conditions not meeting these requirements please contact AR Technical Department. AR recommends the use of bearing plates under hanger end clips for hanger loads greater than 26kN (6000 lb) when used on concrete girders or supports. Please consult with AR Technical Department for custom made hangers with loads other than that listed in this calalog.

*Available in Plain Steel (B), Electro Plated (EP) and Hot Dip Galvanized (HDG)WARNING: Lateral forces must be properly reacted in order to prevent hanger movemen

t. Heavy Ty-Back Inverted 90°- 45° (Inv 90-HTBH-A) Type #2 & #3 - 90° - 45° Haunch Angle Hanger (HRH-A) - 25mm (1") / (HRH-A) - 38mm (1-1/2") This hanger is useful for projects where bridge brackets for formwork is to be installed for forming the bridge cantilever overhang only. These hangers can be used on steel or concrete girders where adequate reaction can be provided by a 4b434b4" diameter high strength stud. Bearing plates are recommended for concrete girders with flange thicknesses less lhan 5" and also for hanger > 6000 lb capacity. Hanger > 204mm length is also available with 90" supplement. Haunch Angle Hanger HRH-A is used to form fascia overhangs on projects having a 1" (25mm) or 38mm (1-1/2") haunch condition. The hanger is fabricated with a 13mm (1/2") dia.

90° HRH-A end clip and a 13mm (1/2") dia. 45° HFR end clip.

Haunch relief heights: Type #2 HRH-A is 25 mm (1").

Type #3 HRH-A is 38 mm (1-1/2").

Note: The safe working load

(SWL) shown here are based on hanger tests where the hanger has been adequately restrained by a ¾" high strength stud.

The actual safe working load of

the hanger is totally dependent on the size and strength of the stud that will be used to provide the hanger reaction at the inverted 90 degree end.

As such the hanger installed

capacity may be less if it is not adequately restrained.

Please consult with AR technical

department for guidance on use

of this product. Please consult with AR technical department for details on AR high capacity 18,000 lb SWL Hangers
