The ARCO Hinge-away is custom built for each specific application. Its design includes consideration for operational requirements, opening dimensions and structural and architectural design. This door is most suited when minimal internal projection is required and also provides slightly higher drive through height than a Bi-fold door.
The door frame is typically constructed from hollow, rectangular, steel sections.
These provide high strength and rigidity with low weight. Often, doors of this type (when used for wide openings) incorporate trussed frame members.
Other components, eg. tracks, brackets etc . are fabricated from steel sections.
The standard finish is a two pack paint system, powder coating may also be available depending on frame size and colour.
Hot dip galvanizing is often specified where corrosive environments or seaside locations necessitate.
The door can be designed to accept a wide variety of cladding and glazing materials.
Toughened/laminated glass, including double glazed units.
Common sheet-metal roofing/wall claddings
Rigid plastic sheeting
Thermally insulated panel
Most Hingeaways are glazed. Typically glazing beads are 50mm wide. Glass type and panel size is regulated by industry standards.
The Hingeaway door requires operational clearances as well as permanent space for its accommodation. These dimensions vary depending on the application and the size and weight of the door.
The door moves on tracks, installed behind the opening nibs. It fits between the nibs, floor and lintel. As the door opens the leaves rotate from the vertical (the closed position) to the horizontal with the bottom leaf coming to rest under the lintel, at the top of the opening.
When open, the door projects one half outside/one quarter inside.
Operational clearances must be carefully accounted for as they impinge on other design criteria, eg proximity of vehicles in front of and behind the door.
Please Refer to Technical sheet C6 for clarification and approximate clearance requirements.
The Hingeaway is automated by the use of:
A drive unit, which includes a torque limiter and independent limit switches with variable speed control.
An overhead drive shaft, between tracks
A control system, which may include safety features such as photo beams, loop detectors etc.
When a power operated Hingeaway door is ordered these items are included as integral components of the door. Motorisation may be fitted to an existing manual door, but this may require extensive modification.
Locking is normally provided on manual operated doors only.
Pad bolts are fitted internally/externally to allow the door to be latched in the closed position. These can be fitted with padlocks for additional security.
Motorised doors are usually locked via the drive unit, however additional security is available by incorporating powered mechanical or magnetic locks.
The Hingeaway door has two leaves (the top leaf is ¼ of the door height, the bottom leaf ¾ of the door height). The leaves fold together as the door opens. When in the open position the leaves are horizontal, folded together with only the thickness of the bottom leaf reducing the opening height, thus maximising the drive through height. The external projection of the open door is ½ of the opening height. The internal projection is ¼ of the opening height.
The Hingeaway is typically used for medium sized openings (ballpark 3m high x 4m wide). It is often used in place of a Foldaway where maximum drive through height is important.
Although it has two leaves, the counterweight balanced Hingeaway has few moving parts. Architectural aesthetics, reliability and long service life make this door an obvious choice for a range of situations where no other solution exists.
