New chain drive barrel assembly unit for Ranger drive units

A range of unsprung chain drive barrel assemblies is now available from GfA UK. The full turnkey packages include end plates, mounting brackets, fully assembled chain drive barrels, Timmer safety brakes and are powered by our Ranger drive units.

Designed by the GfA technical team

Ideal solution for car parks

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.

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.

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 to 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 Ranger FI drive unit.
