Contractor Sino-Thai has deployed four Liebherr luffing jib cranes to work on the construction of a supreme court in Bangkok’s Rattanakosin Island conservation area.
A pair of 125 HC-L 6/12 Litronic luffers and two 112 HC-Ls are working on the four storey building for Sino-Thai, one of Thailand’s largest engineering and construction conglomerates,
Sino-Thai purchased the cranes from its subsidiary STIT, the Liebherr distributor for the country.
The 125 HC-L lifts 12 tonnes and the 50 m jib can be set between 15 and 70 degrees, with a slewing radius of seven metres. The 112 HC-L has the same jib angles and a 45 m jib that can lift 12 tonnes.
“These four cranes were previously used by Sino-Thai on a four-storey hospital project in Bangkok, where the footprint of the building was large, and stringent no-overfly restrictions prevailed,” said Chupak Jirarojveerakul, project manager for Sino-Thai.
“The Supreme Court has a long and narrow footprint, and we have adapted the configuration, deploying the four cranes at strategic points to ensure that all parts of the site are covered.”
The luffing jib tower cranes had to be used to avoid oversailing the Sanam Luang ceremonial ground in front of the site, which lies near Bangkok’s Grand Palace, or the city moat behind the building.
The district is where Bangkok was founded as the capital of the country in 1782, and the City Pillar Shrine – the first building erected – is adjacent to the Supreme Court site, which lies atop an earlier court complex built in phases between the 1940s and 1963.
The four cranes are expected to be working on site for 12 months.
