Sarens Launches New CS350 Climbing System
Spotlight on Sarens’ newest bottom-feeding jacking system
June 2020

Sarens is proud to announce the launch of the new CS350 climbing system, which combines fast operation with bottom-feeding jacking elements. The CS350 is the latest in a new generation of bottom-feeding jacking systems at Sarens, and follows the success of the CS5000 and CS1000 systems. Its features include:

  • 350-tonne lifting capacity
  • 7% allowable side load
  • Low starting height
  • 6-metre unbraced lifting height
  • 3.6m/hr lifting speed
  • 0.3-metre element height
  • 370kg element weight
  • Ground-level access to the element feed system and base unit hydraulic systems

Unique Advantages

The CS350’s bottom-feeding design offers unique advantages over top-feeding systems that require elements to be installed and removed at the top of the element stack. With a bottom-feeding system, there is no need to work at height, which in turn decreases health and safety risks to operators. Another unique aspect of the CS350 is that it can raise loads 6 metres without the need for bracing. For jacking above a 6-metre element stack, a bracing system can be installed to brace between adjacent CS350 element stacks or between an element stack and the load.

Custom Design

To develop the CS350, Sarens looked at existing solutions on the market, considering the pros and cons of each system and identifying desired specifications in terms of vertical and horizontal capacity, footprint, minimum height, self-weight, operating speed, ease of maintenance, and more. The CS350 is a custom-built solution resulting from these in-depth considerations. It was developed 100% in-house, drawing on Sarens’ knowledge and experience in developing the CS1000 and CS5000 and inspired by a clarity of vision for what was possible.

Expert Collaboration

The CS350 was developed between the UK TS engineering team, the RDTS 3D CAD team, and equipment engineers based in Wolvertem. Subcontractors with specialist knowledge in steel fabrication, cylinder manufacture, and hydraulic component layout provided valuable insights throughout development. Operators, equipment engineers, and RDTS engineers also provided design input to ensure the CS350 would be robust as well as easy and efficient to use and maintain.The development team ensured that the CS350 would be economical to transport, ensuring its weight and size would allow for two bases to be transported by a single truck. They also built the CS350 to include a feed system and jacking element handling crane to assist the site team in efficiently feeding in or taking out elements during a jacking operation.

Project Potential

The CS350 promises to offer great advantages in possession work, where timing is important. Sarens also foresees bridge installation and removal projects as key markets. Due to ease of set-up and operation, as well as its ability to raise loads up to 6m without bracing, Sarens expects to see high demand for the CS350. In many cases, it can be used where CS250, CS350, CS600, or even CS1000 and CS5000 systems had been planned.

The CS350 has been brought to market thanks in large part to the individual commitment of our many talented team members. Sarens would like to thank everyone who helped to make this one-of-a-kind system a reality.
