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.
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.
The correct
combination of drive and barrel assembly can be chosen from the selection
charts available from GfA UK.
All Ranger drive units
are compatible with our range of TS control panels and interconnecting
cables allowing a complete ‘plug and play’ solution. You can find out more

500mm square plate now available for
Safedrive®
The new 500mm square plate for Safedrive® eliminates the need for customers to make their own plates in the rare cases where our standard 406mm plate is not big enough for the application. And it gives you the extra reassurance that our technical team have specified and calculated all the load requirementsand had the relevant stress testsconducted, so that the plates are correctly engineered. The 500mm plate can be used with Safedrive®
motors from 350Nm to 650Nm. | ||||||||
