This firm’s trench machines are used for onsite fusion of plastic piping, and are now available in three versions: TM 160, 250 (photo) and 315. The key components of the fusion machine are the heating element, facer, clamping brackets and unit, and rapid-action couplings. The optimized cross-sectional profile of the clamping points makes for easy handling, while reducing weight and increasing stability. The design of the top clamp enables fast and easy fixation, alignment and removal of pipes. Rotating the machine around the longitudinal axis creates a second working position, without changing the pull direction and the hydraulic connection. For documented quality control of the joints, the necessary accessories are offered for fusion data traceability. Weld-fusion execution is compared with the selected standard and then a printout of the parameters can be started. — Georg Fischer Piping Systems, Schaffhausen, Switzerland
