A SENNEBOGEN 683 HD telescopic crawler crane is being used by Koh Brothers Building & Civil Engineering Contractor to expand a large section of Singapore’s underground canal.
The three-year project will improve the efficiency of the canal, leaving it better equipped to deal with heavy rainfall.
Koh Brothers is extending Singapore’s underground canal system as part of the second phase of construction. The trapezoidal wastewater canals and confluences located between Bukit Timah Road and Holland Green will be enlarged to allow up to 30% more rainwater to flow off in a controlled manner.
The telescopic crawler crane is being used to introduce sheet piles for the canal extension. Koh Brothers has attached a PTC 30 HFV vibrator hammer to drive the metre-long sheet piles 15m into the ground.
Operators claim that the 683 HD’s running gear adds to the stability of the crane, and allows it to be manoeuvred quickly and easily. The unit, which is operating from a metal platform that has been built over the canal, is able to perform tasks in a very narrow working area.
The section of the canal that is undergoing expansion is 3.2km in length. The work forms part of the National Water Agency’s $750m project to better prepare the city-state for heavy rainfall.
