A five-pointed Sirio 5rz51 pump with a maximum vertical boom displacement of 50.1 meters. The pump is usually built on a four-axle chassis. Then the weight of the set is 37 tonnes. In special cases, the Sirio 5rz51 can be built on a five-axle chassis, this increases the overall weight to 38 tons, but there is a reduced axle load. In the 5-axle SIRIO 5rz51, each axle has a weight of less than 8 tons. The pump so prepared has the right to legally drive on roads with less load capacity. Sermac consistently uses retractable, telescopic front outriggers in long pump designs, making it much easier to set up the machine on site. The width of the front and rear outriggers is 9.5 m. the Sirio 5rz51 concrete pump model is a development of the previously produced and very successful 5rz48.
The Sirio 5rz51 pump became very popular in Poland and throughout Europe.
