Sarens has added another climbing jack system to its heavy lifting fleet, the 386 US ton (350 tonne) capacity CS350.
It is the latest in the fleet and joins the larger CS1000 and CS5000 versions of the bottom-feeding type jacking systems. Applications will be across multiple sectors but Sarens said it expects infrastructure to be the most popular. Its fast jacking speed of 3.6 metres/hour, small footprint and a 20 foot (6 metre) jacking height without bracing will be key features in helping to minimize ‘possession’ time.
Other features listed by Sarens include: a 7 percent allowable side load; low starting height; 300 millimetre jacking element height; and a 816-pound (370 kilogram) element weight. Adding the jacking elements from ground level offers health and safety advantages over top-feeding systems, Sarens said. The CS350 can be jacked above 20 feet (6 metres) by adding bracing between stacks or between a stack and the load.
Design was in-house by the Sarens engineering team and the system was assembled, commissioned and tested at the company’s global headquarters in Wolvertem, Belgium. It is now ready for its first job which is a bridge installation project in Eastern Europe.
The development team made it economical to transport. Its weight and dimensions allow two base units to be carried on one truck. Also part of it is a feed system and jacking element handling crane to assist with feeding in and removing elements during operation.
