Recommended Specification 

A5000 is custom built for each specific application. Please contact ARCO (Qld) for any technical assistance in design and installation.  Listed below are some of the main design considerations when specifying the A5000:

Operational Requirements

Opening Dimensions

Structural Requirements

Architectural Requirements.

Therefore it is important to accurately measure the opening dimensions and adequately specify any requirements.



Opening Requirements

The A5000 Vertical Lift Counterweight Balanced Door requires operational clearances as well as permanent space for its accommodation. These dimensions vary depending on the application. It is important to take these in to consideration especially the operational

clearances as they impinge on other design criteria, for example the drive through clearances.




Motorisation requires the addition of:

Motorisation Guides

Variable Drive Unit with Manual Release

Independent Limit Switches

Overhead Shaft

Control System.    

When a motorised door is ordered the above mentioned items are included as they are integral components of the door. Motorisation may be fitted to an existing manual door however this may require extensive modification.




Locking is normally provided on manual operated doors only. Pad bolts are fitted internally to allow the door to be latched in the closed position. These can be fitted

with padlocks for additional security.

Locking for motorised doors is usually locked via the motor however additional security is available, for example electric or magnetic locks.



Cladding / Glazing

Being a counterweight balanced door the ARCO (Qld) A5000 Vertical Lift Counterweight Balanced Door can be designed to accept a wide variety of cladding and glazing materials.

The following combinations of glazing and cladding are quite common:

Sheeting products such as Trimdek and Custom Orb
