Civil engineering/construction work

Tower crane construction

We construct, operate and dismantle tower cranes, jib cranes and climbing cranes, which are essential for construction of high-rise buildings and huge projects.

Tower crane assembly and dismantling

We support everything from planning to design and technical assistance, and provide assembly, dismantling, and operation services for tower cranes and other types of cranes.

Seven units of our mainstay 25t lifting tower crane JCC-V600S were used for the construction of City Towers Tokyo Bay, a 33-storey condominium tower approximately 120 m high above ground.
It was a spectacular sight to see 7 tower cranes lined up all at once.
