Adoption in the railway industry: Measures against the falling of cranes and running rails due to earthquakes.

【Factory Safety Measures】By reinforcing the fittings, we propose to reduce the risk of instant drop or derailment of overhead cranes and running rails due to earthquakes and other factors!

Imai Iron Works has been manufacturing various cranes as a crane manufacturing authorized factory by the Ministry of Labor. Overhead cranes are essential equipment for transporting heavy objects and are used in many manufacturing plants, including automobile and railway factories. However, in recent years, numerous earthquakes, such as the Great East Japan Earthquake and the Kumamoto Earthquake, have occurred, leading to many accidents on site, including: 1. Derailment due to bouncing and lifting, resulting in the overhead crane falling. 2. Falling of the running rails due to insufficient strength of the fixing brackets. As a result, there have been cases where employees were trapped under the rails, and the reactivation of factories was significantly delayed, causing major impacts both in terms of safety and economy. Imai Iron Works proposes measures to prevent the falling of cranes and rails using the "Crane Gripper" and "Rail Keeper," which are listed in the indicators of the Japan Crane Association. Both the "Crane Gripper" and "Rail Keeper" are patented. *For more details, please download the catalog or feel free to contact us.

basic information

【Basic Structure】 ■ Integration of the saddle and gripper. ■ Maintains a gripping state while ensuring a certain gap with the rail. ■ Slides along the running rail and maintains a gripping state to achieve a structure that is physically difficult to disengage. * For more details, please download the catalog or feel free to contact us.
