Sarens has built the heaviest and strongest crane in its line-up and is able to move around the jobsite even when fully rigged.
The first of the third-generation ring-based cranes at the company, the SGC-250 has a maximum load moment of 250Tm (tons-meters), enabling the machine to lift five metric tons.
Even when it is fully stretched to its 100m radius capacity, the crane is still capable of lifting two metric tons – and that being true in the event the ground pressure is below 25T/m².
The main boom, which is now 118m, can be extended up to 160m and the jib can be extended up to 100m, meaning the vehicle can reach a height of nearly 250m or a radius of 275m.
All on a double ring
A Sarens spokesperson said, “This flexibility guarantees that Sarens is capable of building whatever is needed by the client, all on a double ring design of no more than 48.5m, which constitutes the outer diameter.
“In addition, the crane can operate two hook blocks: one on the main boom and one on the jib. In this way, the crane can cover each spot on the jobsite while still offering the combination of strong capacities and fast operations.”
However, the most unique feature of the crane is its ability to move from one lifting position to another, even when fully rigged. This is possible, due to the two sets of wheels the crane has: one for slewing 360° and one for travelling. The second set is hydraulically retractable and is pushed out whenever the crane needs to travel.
“This is a characteristic that not only has no precedent among the Sarens fleet of cranes, but constitutes a breakthrough for the entire global crane industry,” added the Sarens representative.
