Tiong Woon Corporation in Singapore has selected several Potain topless tower cranes for a housing project in western Singapore, demonstrating the country's shift to precast construction. The cranes, including MCT 565A and MCT 1005 models, will handle heavy concrete elements and PBUs (pre-assembled bathroom units), speeding up construction with their high capacity and efficient design. CEO Michael Ang highlights the cranes' suitability for space-constrained job sites.

Several high capacity Potain topless tower cranes — a mix of MCT 565A and MCT 1005 models — purchased by Tiong Woon Corporation (TWC) are getting to work on a new government housing project in western Singapore.
The country's increasing shift to precast construction in housing projects is fuelling demand for high-capacity cranes to lift heavy concrete elements. Local government regulations require all new Housing & Development Board (HDB) apartments to be fitted with PBUs (bathroom units pre-assembled off-site). On the Jurong West N4C22 project, the cranes will handle all precast components, including its 22 ton dual-PBUs.
In addition to Potain cranes already operating on the job site, new units will be installed in the coming weeks with each working on a different tower block. All will be assembled to a height under hook of 45 m. The MCT 565A cranes are working with jibs from 30 m. to 35 m., which gives them tip capacities of 22.5 tons to 18.3 tons. Meanwhile, the MCT 1005 will operate with either 40 m. or 45 m. jibs, corresponding to tip loads of either 28.2 tons or 24.8 tons.
The MCT 1005 cranes have a maximum capacity of 50 tons and can lift 25 ton loads at speeds of up to 31 m/min. The MCT 565A cranes have a maximum capacity of 32 tons and can lift 24 ton loads at up to 22 m/min. All cranes can handle the 22 ton dual PBUs with ease. The PBUs speed construction by arriving on site partially tiled and pre-assembled with copper piping, sanitary ware, window frames, ceiling, bathroom cabinets and a waterproofing system. This means they can be quickly lifted and installed with minimal finishing work.
"Job sites in Singapore are often space constrained, so the compact and topless design of the MCT 565A, paired with its short counter-jib, is well suited for our projects," said Michael Ang, group CEO of TWC. "We are also deploying the MCT 1005 with a short counter-jib configuration, which provides good reach in our key projects. We are confident that both cranes will serve the project's requirements effectively."
