Somfy LT – Emergency Hand Crank Motor (used & refurbished | tested)
“I am the motor that keeps going even when the power fails – reliable, robust and ready for emergency operation.”
I offer you used Somfy LT tubular motors with emergency hand crank function (NHK, CSI, RDO) – durable mechanical drives for roller shutters, large rolling doors and sun protection systems where reliability and safety are top priority.
These motors are based on Somfy’s proven LT technology and are additionally equipped with an emergency crank mechanism that allows manual operation even during a power outage.
This is especially valuable in garage and rolling door installations:
If the power fails or the controller malfunctions, the door can still be opened or closed using the built-in crank – ensuring you always remain flexible and able to act.
Each motor is cleaned, tested and assessed according to EU safety standards (GPSR) in my certified craftsman workshop. The result is a durable, inspected drive that ensures safe operation in mechanical rolling-door systems.

Application: Rolling doors & systems with emergency operation
Somfy LT motors with emergency hand crank (NHK, CSI, RDO) are designed for use in rolling doors, industrial doors and larger roller shutter systems.
They combine the proven mechanical limit switch technology of the LT series with a robust emergency operation function that ensures operation even in the event of power failure or system malfunction.
This makes them ideal for garages, workshops and commercial facilities where a manual emergency opening is required or technically advisable.
 
Sustainability meets safety
Professional refurbishment extends the service life of these high-quality drives – a sustainable alternative to purchasing new equipment.
All motors offered are tested according to GPSR and meet current safety and performance standards.
Each motor originates from trusted sources or my own stock, and is only resold after successfully passing a full functional test.
