Employment of this method means the construction is completed more quickly and with reduced impact to the surrounding areas and community, the MTRC says.  (Danny Chung)

Bridge deck segments are traditionally cast in-situ on site but this usually entails implementing traffic diversions and causes other inconveniences to people living and working nearby.  (Danny Chung)

At Wong Chuk Hang, the viaduct deck segments are pre-cast offsite and slotted into position using the “beam-and-winch” equipment which is quieter to operate and generates less dust.  (Danny Chung)

The MTRC says because the beam and winch machine is only one tenth the size of a typical viaduct launching gantry, less time is required to deliver and set up, thus doing away with road closures that could last for weeks on end.  (Danny Chung)

The MTRC says because the beam and winch machine is only one tenth the size of a typical viaduct launching gantry, less time is required to deliver and set up, typically four to five days compared with a month for a traditional gantry. This does away with having to large-scale road closures that could last for weeks on end. (Danny Chung)

 

Beam and winch method also allows work to proceed at different locations at the same time and thus help shorten construction period. (Danny Chung)

“We use the latest proven techniques to minimize the impact to the community. With the “Beam-and-Winch” equipment, not only do we complete the South Island Line (East) project faster, the residents can also enjoy the convenience of a rail service sooner,” says MTRC’s lead project manager – SIL, Mark Cuzner.
