Performance Level D door drives for guard doors & machine safety doors
Electric door drive for automatic machine doors and all cnc machine tools
The engineers at Langer & Laumann are able to draw on many years of experience and know-how in the development of door drives for passenger elevators. The new generation of TSG Safety door drives is certified by TÜV (TÜV-Nord) according to DIN EN ISO 13849-1 (machine safety) Performance Level d. Thus, our new decentralized security system for machine safety doors complies with the European Machinery Directive 2006/42/EC.
TSG Safety Guard Door Drive
The TSG Safety door drive for machine safety doors is a compact, maintenance-free and splash-proof IP54 DC motor with worm gear. The drive is quiet and effective due to its low self-locking.

The machine door drive has built-in obstacle detection and automatic reversing, so that an immediate change of direction is triggered if the door encounters an obstacle in the machine-passage and prevents irreversible damage. We have developed the TSG Safety Web Interface, a parameterisation and control software that is frequently used in the machine tool industry and allows the easy and intuitive commissioning of your safety machine door.
Langer & Laumann provides you with the TSG Safety a complete solution for your machine safety doors with a reliable door actuator and integrated safety as well as support on request and during commissioning. We also offer you our support in the design-in of mechanics as well as the electrical connection. The security system includes the technology to apply a safe speed and power limitation according to DIN EN ISO 13849-1 (Machine safety) Performance Level d for horizontal and vertical doors.
The door actuator TSG Safety is universally applicable for all horizontal and vertical machine safety doors and lift gates. Through its controlled system, the automatic door drive allows a quiet and smooth opening and closing of the machine safety door. The cabling effort is minimal and the integration into the existing control cabinet or mounting directly to the door operator is straightforward.

Door actuators for machine protection doors
Door automation with performance level d door drives for machine protection doors and machine guards, can be used in machining centers, lathes-, milling machines and machine tool spindles of any kind.
There is no need for light barriers, tow-hand operation, additional switches, safety edges or other sensors with our machine safety door drives. The technology of the TSG Safety supports the implementation of a safe speed and power limitation for horizontal and vertical machine doors up to 1000kg. The controller has a built-in collision detection and can also be operated manually when switched off, so there is no danger to the operator by inclusion. Our door actuators fulfill the following security-related standards:
- DIN EN ISO 13849-1 Machine safety
- DIN EN ISO 23125 Machine Tool Safety Lathes
- DIN EN ISO 16089 Safety of Machinery Grinding Tool
- DIN EN 953 Machinery Directive: Guards
The TSG Safety door drive has the Safety Integrity Level (SIL2) and Performance Level d Category 3 and includes the following protection functions for machine doors:
- SS1 (Safe Stop 1)
- SLT (Safely Limited Torque)
- STO (Safe Torque Off)
- SLS (Safely Limited Speed)
Our door drive is resistant to all common coolants and lubricants, has a wear-resistant toothed belt drive and is therefore virtually maintenance free. On machine tools, CNC machining center and CNC lathes and milling machines with existing mechanical, hydraulic or pneumatic safety doors the TSG Safety is easy to retrofit with motor and tooth belt.
TSG Safety benefits
- Durable door drive
- Fast opening & closing times
- No additional sensors required
- Maintenance-free, compact and space-saving
- Simple commissioning due to intuitive operation on device
- Independent of the opening width and the opening direction (horizontal / vertical)
- Integrated Safety according to DIN EN ISO 13849-1 Performance Level (PL) "d"
- Personnel protection according to EN ISO 23125, DIN EN ISO 16089, DIN EN 953
- Two housing shapes available (internal: in the control cabinet, external: directly on the drive)
- Operation, parameter settings and backup the values of the safety gate drive via PC / notebook possible
