Becker R L Series M05 HK Tubular Motor Repair – Specialist Workshop for Roller Shutters & Awnings with Emergency Crank (NHK)
 
Your Becker tubular motor says:
“I am the motor you can rely on – even when the power fails.”
“With my emergency crank, I keep the roller shutter and awning mobile – reliable, robust, and safe.”
“At Thomas Reh, my mechanics were overhauled, inspected and re-adjusted – ready for many more years of service.”
 
The reliable Becker motor with emergency crank
The M05-HK motors of the Becker R and L series belong to the mechanically controlled drives for roller shutters and articulated-arm awnings. Their integrated emergency crank (NHK) enables manual opening or closing in the event of a power failure – a decisive advantage in safety-related or weather-dependent applications.
The motors are known for their robust construction, precise limit switch adjustment, and smooth operation. They are low-maintenance, durable, and can, in most cases, be professionally refurbished and returned to service. This keeps existing systems fully functional without requiring a complete new installation.
