Products Floor Hatch (90hatch) | ANANDENKI CO., LTD.

The 90 Hatch is an indispensable safety floor hatch and safety fence combined.
The 90 Hatch was designed by THE KANSAI ELECTRIC POWER CO., INC. through their Quality-Control circle about 20 years ago, and ANANDENKI was chosen as the exclusive maker. Since then, nearly 1,000 units of the 90 Hatch have already been installed at numerous facilities in Japan, such as nuclear, thermal and hydraulic power plants, transformer stations, public facilities such as sewage plants and pump stations, and so on. The main applications at nuclear and thermal power plants are turbine building, nuclear reactor building, ancillary facilities building, and radioactive waste treatment center building.

The 90 Hatch dramatically reduces the time and cost required for hoisting work.
