At the Deep Tunnel Sewerage System project in Singapore, Guan Chuan Engineering & Construction’s Sennebogen 6133 E telescopic crawler crane carries out sheet piling work for earth retention.
Guan Chuan Engineering & Construction has used a Sennebogen 6133 E telescopic crawler crane to help carry out excavation works on the new Deep Tunnel Sewerage System (DTSS) in Singapore.
In order to help carry out excavation work on the new Deep Tunnel Sewerage System (DTSS) in Singapore, Guan Chuan Engineering & Construction used a Sennebogen 6133 E telescopic crawler crane.
Due for completion in 2025, the DTSS project is an expansion of the existing network of sewers. It involves the construction of new deep tunnels in the south and west of the country. These will include a 30-kilometre tunnel for used water, an industrial used water tunnel measuring 10 kilometres long and a further 60 kilometres of link sewers. The new sewers will transport waste and used water to Singapore’s Centralized Reclamation Plants for purification into high-grade clean recycled water.
The DTSS scheme, expected to be finished in 2025, is an extension of the new sewer network. It requires the building in the south and west of the nation of new deep tunnels. This will provide a 30-kilometre tunnel for used sewage, a 10-kilometre industrial water tunnel plus an additional 60 km of interconnection sewers. The new sewers would transport sewage and used water into high-grade clean recycled water to Singapore’s Centralized Reclamation Plants for purification.
Guan Chuan used its 6133 E crawler model to carry out sheet piling work for earth retention as part of the project’s second phase. The works saw the telescopic crane hold up the silent piler main body, the pile auger and sheet pile, with weights often in excess of 20 tonnes.
As part of the project’s second phase, Guan Chuan used its 6133 E crawler model to carry out sheet piling work for earth preservation. The works had the telescopic crane carrying the main body of the silent piler, the auger pile and sheet pile, with weights sometimes reaching 20 tons.
A crane operator with Guan Chuan named Mohamad Hamid said, “Holding on to the silent piler main body while lifting and sliding in the sheet piles is often challenging. With Sennebogen’s quality boom structure, I only need to focus on sliding in the steel plate, nothing else.”
The 6133 E crawler features a six-section 52.2 metre main boom and a 5.4 metre track telescopic crawler undercarriage, which can be removed and re-attached by remote control. The largest crawler in the manufacturer’s product line, the machine’s counterweight can also be loaded and unloaded remotely.
A six-section 52.2 metre main boom and a 5.4 metre track telescopic crawler undercarriage are included in the 6133 E crawler, which can be detached and re-attached by remote control. The main crawler in the product line of the manufacturer, the counterweight of the unit can even be remotely loaded and unloaded.
Guan Chuan’s site supervisor on the DTSS project, Manimozhi Muthukumar, put it this way:“There is no delay and no need for extra manpower. The Sennebogen 6133 E can retract its 5.40 m wide track to 4 m for self-loading to the low-loader.”
Further, He also said, “There isn’t a need to have auxiliary cranes to carry out mobilization and demobilization. This makes my work a lot easier so I can safely focus on deploying my men around the site”
The crane concept was purchased by Guan Chuan at the 2019 Bauma construction fair in Germany. David Liaw, Managing Director of the firm, said the development of the 130-ton crane and its ability for load and scope were key determinants in its purchasing decision-making procedure.
Liaw further stated, “What has particularly convinced us for years is the robust construction, the high reliability and the easy transport. This significantly reduces operating costs.”
