Company HİDROAKTİF has developed a totally new Caterpillar Style Series which has been specifically designed according to the requirements of large diameter pipeline construction. The advantage of the Caterpillar Style Series is the optimize utilization of a machinery concept with its unique focus on today’s and future design features. The cabin is placed in a position which gives the operator an ideal overview of the operation environment. On all Caterpillar Style models the crane is mounted in front of the machine which can be manipulated from inside the cabin. This provides excellent operating safety as well as great operators comfort.
The sufficiently dimensioned engines which are electronically governed grant continuous rpm of either 1.500 rpm or 1.800 rpm developing 50 Hz or 60 Hz AC power at the directly connected synchronous generator.
The generator rpm and therefore the delivered frequency remains constant under changing load conditions which means varying numbers of welding power sources being switched “on” or “off” do not influence the frequency and the voltage delivered during the welding procedure. This is a precondition to eliminate welding failure and therefore reaching excellent welding results.
The over dimensioned engine radiator enables the machine to work under ambient temperatures of up to +52°C. An arctic package which is available as an option keeps the machine in operation up to temperatures, as low as –40°C. The installed crane with up to 7 tons lifting capacity enables the Caterpillar Style models to carry all existing welding shelter so even small to medium diameter pipes.
The hydrostatic driven under carriage lets the machine turn on the spot through counter rotation and guarantees sufficient ground clearance as well as full operation up to 30° slope conditions. The comparatively low operation weight in combination with wide track shoes gives the Caterpillar Style model a low specific ground pressure and keeps it in operation in swampy environment where other equipment possibly sinks in.
The heated operator‘s cabin is rollover protected, an air condition as well as a stand-by heater for arctic environment are optionally available.
Upon customer‘s request a two stage piston compressor delivering 975 l/min at 14 bar can be mounted on the Caterpillar Style models.
