Cranes in action

Both Kinjo Juki and Maruhiro Juki Kogyo have crane yards where monster cranes and
excavators stand by, ready to do their jobs at foundation construction sites.
Kinjo Juki’s equipment bears the hibiscus trademark,
and Maruhiro Juki Kogyo machines sport their unique mascot characters,
so both companies’ equipment stands out anywhere.

Mastertech 7070-1F at work on a bridge pier footing project

This road, part of an infrastructure development project on Okinawa’s west coast, will improve access to the Naha Airport. We found Kobelco Mastertech 7070-1F cranes belonging to Maruhiro Juki Co., Ltd. hard at work building the pier footing for the Maki-minato elevated bridge, the starting point of the Urasoe-kita road. We were even able to get into the operator’s seat, something that does not happen very often.
