A flame-proof housing () of the protection type ex-d is made from two sheet metal blanks that are bent in a u-shaped fashion. They then are fitted into one another and subsequently welded together by means of a peripheral fillet weld without welding seam preparation. A large opening () can be provided on one side of the housing (), which can be closed with a threaded cover or with a flat cover.

Disclosed is a crane rail made from a roll-formed steel sheet strip. Said crane rail altogether comprises a top flange and a bottom flange. A support flange that has a triangular cross-section is additionally embodied on the top flange. The edges of the steel strip are laser-welded to the web.

A joint connector for the lower flanges of adjoining running rails is assembled from two abutment pieces that each is seated in a lower flange of a respective rail that forms the joint. By use of centering devices, the correctly aligned positioning of the two abutment pieces is assured, wherein the abutment pieces transfer their aligned positioning to the lower flanges that meet each other without offset at the joint and the positioning cannot be negatively affected by transverse forces. The connection also provides a positive-fit in a transverse direction of the rails. Another joint connector arrangement connects the two running rails in the region of the top side. Abutment pieces in this case are seated as riders on a support rib and are connected to each other by tension rods.
