Lifting solutions for precast concrete tunnel segments in the TBM industry
Do you work in the TBM industry and are you searching for handling solutions for the production or transport of precast concrete segments for tunnel walls? Then Aerolift is the partner you are looking for! We offer complete lifting solutions for the handling process of precast concrete tunnel segments and tunnel lining segments. From production to positioning the concrete segments inside the tunnel wall. All our lifting equipment is able to handle precast concrete tunnel segments, keystones and lining segments.
Production of concrete tunnel segments
Handling at the production factory using a vacuum lifter goes easily and quickly. To demould, lift or turn, no embeds are needed. Moreover, due to the equal pressure distribution of the vacüum pad, it is possible to demould after 8 to 10 hours. If you demould by embeds the hardening time will at least be 24 hours!
The precast concrete tunnel segments are produced with the convex side facing upwards (extrados). To meet the requirements of the tunnel boring machine (TBM), the concrete tunnel segments need to be rotated 180 degrees. This rotational movement can be done by a standalone tilting device or by a vacuum lifter with a built-in function to demould, lift and tilt.
Also applicable for other concrete parts
Next to the production of concrete tunnel segments, Aerolift vacuum lifters can be used for handling all kinds of concrete parts. Learn more about the handling process elements in a concrete production factory, and check out the case of one of our clients!
Transport of concrete tunnel segments
We designed a clamp lifting device to handle a stack of concrete segments. The clamp is able to load a stack of concrete tunnel segments from and onto a truck, or down the tunnel shaft into the TBM area.
Handling in the TBM: segment handling by vacuum lifters
To handle concrete segments in the TBM, we developed two separate vacuum lifting systems. The first vacuum lifter moves the tunnel lining segments and keystones to the erector. During handling the suction pad is rotated 90 degrees to match with the erector’s position.
The second vacuum lifter operates as part of the erector and positions the concrete tunnel segments inside the tunnel wall. To meet all required positions the device is able to turn 360 degrees.
