The choice of door is influenced by a number of important factors; such as traffic volume, type of vehicle traffic, processing equipment and access control.
The dimensions of industrial doors can greatly vary depending on the type of door required, for example : loading bay doors, drive-in/drive-through doors.
A drive-in/drive-through door, or level access door, typically has a clearance of:
|Clearance dimensions drive-in/drive-through doors:|
|Width:||3500 mm - 4500 mm|
|Height:||4200 mm - 4500 mm*|
* The lorry’s maximum head clearance plus a specified safety margin.
The clearance of a loading bay door typically depends on factors such as:
The clearance height can be determined by the lorry’s’ maximum head clearance (+ safety margin) and the bay height. The lorry’s’ maximum head clearance fluctuates between 3800 mm and 4200 mm, for most air suspension lorries.
The lorry’s’ maximum internal width is ± 2500 mm. In order to load and unload over the entire width of the lorry it is imperative that the door width is at least equal to the lorry’s internal width.
We therefore advise the following clearance dimensions for loading bay doors :
|Clearance dimensions loading bay doors:|
|Width:||2800 mm* - 3200 mm|
|Height:||(lorry's roof height + safety margin) minus bay height|
* By introducing wheel guides the margin of error is decreased so a relatively smaller door width can be used.
