BL - BEAM
LAUNCHER
The recognized technology for construction of short span
bridges with precast concrete beams. Precast beams are usually lifted and
placed on the pier heads using cranes or other hoisting equipment from the
ground below. However, for bridges crossing over water or viaducts with high
piers and/or difficult ground conditions, a BL is commonly used to lift the
precast beams in-place.
The advantages of NRS Beam
Lancher (BL) are:
- Fast and efficient beam erection - average erection cycle 1 beam/hr
- Easy to assemble
- Reduced manpower
- No temporary ground supports required
- Self-launching
- Easy to adapt to suit new projects
