About us
Locker manufacturer – for over 35 years
The roots of LockTec GmbH go back to the Scottish company RAAND, which was already producing electronic locker systems for railway stations and airports worldwide in the 1980s. As locker systems ideally complemented the product range of the SITEC Sicherheit + Technik group of companies (www.sitec.de), Managing Director Olaf Clausen took over the Scottish company and most of its employees in 1997. He founded LockTec Ltd. in Edinburgh as well as LockTec in Weissenbrunn.
As the original inventor of patented lockers for goods delivery, LockTec developed the so-called ‘Last Mile’ solution back in 1997 and has since supplied postal and courier services worldwide. In recent years, the company has perfected the fully electronic locker system Locksafe and has also expanded its product range with innovative cool lockers and the Velosafe bicycle garage. All products are manufactured within the group using state-of-the-art laser, punching, and metal processing machines—quality ‘Made in Germany’! This keeps LockTec always one locker length ahead.
LockTec Company History
The history of the parent company began in 1954, when interior designer Heinz Clausen founded a small joinery in Kronach. The company focused on interior fittings and shopfitting. With the simplest means and two employees, furniture and fittings for the local retail sector were designed, manufactured, and assembled.

When the rented premises became too small, a new facility for 25 employees was built in 1960 a few kilometers away at the current location in Hummendorf.

In June 1975, the son Olaf Clausen took over management and founded SITEC GmbH Sicherheitstechnik.
In the years 1980, 1985, 1990, and 1996, the company and office buildings were expanded. Today, SITEC manufactures on a production area of 5,500 m2 and has remained loyal to the Hummendorf location.

As locker systems fit perfectly into the business portfolio of the corporate group, Managing Director Olaf Clausen founded LockTec Ltd. in Edinburgh and LockTec GmbH in Weissenbrunn in 1997, acquiring the Scottish company RAAND as well as a large part of its staff.

LockTec develops the first parcel stations for postal and courier services as so-called 'last mile' solutions.

The technology for delivering packages at a machine is being registered for patent protection.

The first 20 networked parcel stations are being delivered to the USA.

The first demo systems are being delivered to the holy pilgrimage site of Mecca in Saudi Arabia. To date, LockTec GmbH has delivered 120 electronic luggage locker systems to the mosques in Mecca and Medina. The systems are heavily frequented and are used by pilgrims for the secure storage of their luggage.


The 1st generation cool lockers with cooling function are installed in a Swiss shopping center.

The first twelve electronic luggage locker systems of the latest generation – Locksafe5 – are being delivered to SBB (Swiss Federal Railways) at Geneva station. The Locksafe5 systems are equipped with wider, barrier-free operating stations featuring a touchscreen display and, thanks to their exceptionally solid construction, offer optimum security.

The 3rd generation of cool lockers is being promoted as an innovation by the Federal Ministry for Economic Affairs and Energy. cool lockers are now available not only with a cooling function but also with a deep-freeze function, and of course also in a temperature-controlled version.

The new storage and logistics hall of the company group is ready for occupancy. 750m2 of space is now available for goods receipt and for material orders for large-scale projects.

Delivery and commissioning of the 'new addition' to the machine park. With the new milling machine, three-dimensional parts made from aluminium, plastic, insulating materials, fiber composite materials, and wood-based materials are now also being manufactured.

LockTec installs the latest generation of Velosafe bike boxes at the Inselhalle Lindau, the new congress and event location on Lake Constance. Bicycles can be parked spontaneously, without prior registration, in the modern and secure bicycle garages. There is also the option to charge e-bikes inside the boxes.

In autumn, LockTec will deliver ten Locksafe5.1 locker systems to the Swiss Federal Railways SBB at Bern station. The systems feature the latest LS-OS software.

The second batch of the locker system for the 'kiekmo' project by Haspa has now been put into operation. Using an intelligent app, anyone can rent the lockers for free: for the storage of shopping bags, purses or sports equipment. A great service that Haspa offers with 'kiekmo'.
Give it a try!

With the new portal milling machine ‘PORTATEC’, three-dimensional parts made of aluminium, plastic, insulating materials, fiber composites, and wood-based materials can now be manufactured.
The new laser welding robot ‘TruLaser Weld 5000’ enables semi-automatic production of parts made of stainless steel, steel, and aluminium. The manufacturing of components is now even more precise and efficient.
The new profile processing center also enables more efficient manufacturing of steel profiles.
The new machines are also part of the contract and subcontract manufacturing offering from SITEC.

LockTec invests in quality: repeat accuracy and precision in milling and drilling work on steel profiles thanks to the new machining center.

New incoming orders require an expansion of our production capacities. Therefore, in September 2018, part of the manufacturing of locker systems will be relocated to Kronach into an acquired hall.

The sudden death of Olaf Clausen marks a profound turning point for the Clausen family and the corporate group. His son Johannes Clausen is taking over the management of LockTec GmbH, while his son Lukas Clausen will assume the management of SITEC GmbH (www.sitec.de).

The new Easy-Form 220/40 Plus precision press brake ensures greater productivity and precision in CNC bending.
The new PT 1350 grinding and deburring machine guarantees a very high processing quality of our sheet metal parts.
And the new welding robot enables automated MAG welding with even better results.
Further information about our machinery can be found on the SITEC GmbH website.

The passing of Olaf Clausen has made a reorganization of the company structure necessary. The companies LockTec and SITEC are now part of the Olaf Clausen GmbH & Co. KG corporate group.
In 2022, the company group began constructing a biomass heating plant and the associated wood chip storage facility as part of its sustainability strategy (see image). In addition to heat generation, a new combined heat and power system also supplies electricity for the buildings.

The TruMatic 6000 fiber punch-laser machine enables flexible, fast, and continuous production. It produces fully automatically, with high quality, sustainably, and in a versatile manner.
In addition, capacities in metal processing are expanded by a new TruBend 7050 bending machine.
Further information about our machine park is available at lohnfertigung.sitec.de.

The corporate group completes the biomass heating plant and begins processing pallet waste into wood chips for it. In addition, the group donates over 1,000 trees for the reforestation of the Frankenwald.
From Australia to Cyprus – locker systems from LockTec can be found all over the world. And it doesn’t stop there: the acquisition of new machines to expand production and extend operations is already planned.
