Extendable module for maintenance works designed to accommodate maintenance crews and carry out technical works in field conditions. In transport configuration, the area is 15 sq. m; after deployment it increases to up to 20 sq. m. The module can be installed on a chassis or a prepared site. Insulation and an electrical network allow the module to be used in various operating conditions.

The structure is based on an all-welded steel frame designed for repeated transportation and deployment. In folded configuration, the module has the dimensions of a 40-foot shipping container, simplifying transportation.

The module's defining feature is the transformation of the working space. The base area of 15 sq. m is increased to 20 sq. m via a hydraulic system after deployment. The additional 5 sq. m allows more working space to be organised for the maintenance crew and necessary equipment without increasing transport dimensions.

The module is insulated with basalt wool and equipped with an electrical network. The fit-out can be supplemented with equipment to suit the maintenance crew's tasks. The structure can be used as a standalone workspace or as part of a temporary maintenance base.

The extendable module is suitable for maintenance and technical works at defence infrastructure facilities, industrial and agro-industrial enterprises. The option to mount it on a chassis extends its applications to sites where mobility and fast relocation between facilities are essential.
