Skidding / Caisson Launching

Our newest innovation

Move heavy structures with a hydraulic skidding system

One of the biggest challenges in the construction industry is moving and positioning heavy structures, especially in confined spaces or restricted environments. Normally, moving the structures would be difficult, but a skidding system makes the work easier. They are particularly useful in locations where space is limited or where using a crane is not an option.

Our track system is developed for repeated movement of heavy loads, such as moving bridge sections during bridge launching.

Advantages of our skidding system

The Bygging-Uddemann hydraulic skidding system is distinguished to others by being extremely robust (can handle loads up to 20,000 tons) and consist of two main components; skidway beams and steel track.

The skidway beams are skidding system concrete support on which the object to be moved will be skidded from the beginning to the end of the transfer lane, but also where the object will rest between transfers.
The steel tracks consist of 20mm x 300mm steel plates installed on structural concrete (continuous beams) on a base rest and fixed with mortar and screws embedded in concrete. The sides of the steel tracks allow skidding units to grip and pull to horizontally move the object.

Our hydraulic skidding equipment units (IP-CCVs) consist of jacks sitting on a base plate. The base plate has low friction pads that are attached underneath for sliding over the steel track. The skidding system can be used either at ground level or at a height and it has a user-friendly construction that easily adapts to each load size. This is because although each unit is small, linking several units provides an enormous lifting force.

For many tasks, a hydraulic skidding system is a much safer and more effective solution for moving complex objects compared to cranes.

FAQ

What makes Bygging Uddeman skidding system different from others?

Our skidding system is unique in its combination of heavy lifting and skidding technology with the latest material developments in low-friction plastic and epoxy-treated sliding surfaces.

Our skidding equipment is a lightweight system with a very low construction height, which makes it easy to both set up and use. The system is very suitable for use when moving objects with limited insertion space.

In the development of associated launch equipment, we have strived for simplicity and durability. The simplicity means that the system can easily be modified in lifting / moving capacity as entire skidding units (IP-CCV units) of 250 tons can be easily connected or removed as needed.
Durability has been achieved by minimizing the number of moving parts and using a low-friction skidding technique instead of traditional bearings. We have carried out over 2000 successful relocation work with a load weight from 3,000 tons up to 18,000 tons.

How does a skidding system work?

Each skidding unit (IP-CCV-unit) can lift 250 tons and carry its load along a therefore designed transfer lane. Lifting power is provided by two lifting jacks sitting on a base plate. The base plate has low friction pads attached underneath for sliding on the transfer lane’s steel track. When not under load the units rest on four spring loaded wheels for easy relocation along the transfer lane.

The pushing jack has two 12,5 ton cylinders. A grip head has jaws gripping on a steel track mounted on the transfer lane.

What does IP-CCV mean?

IP-CCV Means: Individual Pushing Caisson Carrier Vehicle.

How fast is a skidding system?

For caisson transfer the average speed is estimated to be 12 -17 m per hour, with a maximum of approximately 25 m/hour. For other applications the speed is depending on pump capacity (liter/minute) and number of IP-CCV units operating.

What size does a skidding unit have?

Our skidding equipment is a lightweight system with a very low construction size. 1215x630x595 (LxWxH)
