Previously, barrel assemblies were only possible for our direct drives such as tube motors and Safedrive®. The new chain drive option comes as a result of our technical team working to meet customers' requests.
Designed by the GfA technical team
The chain drive arrangement allows the drive to be mounted inboard facilitating a between walls fix. This means customers can use the system where site conditions don;t allow a direct drive to be used, such as car park applications with limited side clearance.
Ideal solution for car parks
The Ranger chain drive barrel assembly design allows rapid site installation due to the unique barrel retention system which makes use of our proven barrel assembly drive end kit originally developed for our DLA Fire shutter drive packages. Using a stepped drive end shaft to which is fitted a bearing held in place by a circlip, the bearing then locates in to the bearing holder and is held in position by a spring rod retainer, allowing the barrel assembly to be dropped in place and secured. The system incorporates drive chain tensioning slots on the "Top Hat" mounting bracket allowing our 32rpm and 48rpm Ranger drive units to be mounted either horizontally or vertically. For high opening speed shutters or high usage single phase applications the system can also be fitted with the 80rpm Range FI drive unit.
Four barrel sizes (101.6mm x 3.7mm, 127mm x 3.2mm, 139.7mm x 3.2mm and 168.3mm x 5mm) and four Ranger drive units (Ranger 90, Ranger 90W, Ranger 150 and Ranger 140 Fi) are available, allowing doors up to 6m wide x 6m height to b driven, including high usage doors.
The correct combination of drive and barrel assembly can be chosen from the selection charts available from GfA UK.
