今井鉄工所 List of Products and Services

The "Crane Gripper" is a device that reduces the risks of derailment and falling due to earthquakes. It can respond to both lateral and vertical shaking. After a disaster, ceiling cranes can be used at an early stage, allowing normal operations to resume. Additionally, it prevents derailment of ceiling cranes that can occur during regular operations. 【Features】 ■ Structure that minimizes contact between the rail and the claw section ■ The claw section follows the lateral undulations of the rail ■ Easily installable without modifications to existing cranes ■ Additional installation possible on box structures or saddle end faces with covers *For more details, please download the PDF or feel free to contact us.

Imai Iron Works has manufactured numerous cranes as a factory authorized by the Ministry of Labor for crane production. Overhead cranes are essential equipment for transporting heavy objects and are used in various manufacturing facilities, including automobile and railway factories. However, in recent years, many earthquakes have occurred, such as the Great East Japan Earthquake and the Kumamoto Earthquake, leading to numerous 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.*

Ceiling cranes are essential equipment used in various manufacturing industries, including automobile and railway factories, for transporting heavy objects. However, in recent years, numerous accidents have occurred on-site due to the frequent occurrence of massive earthquakes, such as the following: 1. Derailment caused by bouncing or lifting, resulting in the ceiling crane falling. 2. Falling of the running rail due to insufficient strength of the fixing hardware. As a result, there have been cases where employees were trapped under the crane, and the resumption of factory operations was significantly delayed, leading to major impacts on both safety and the economy. By introducing the following products, we can prevent derailment and sudden falls of ceiling cranes caused by earthquakes. 'Crane Gripper' By integrating the saddle and gripper, it maintains a state of gripping the rail, making it physically difficult to disengage. 'Rail Keeper' It has greater strength than conventional hook bolts, reducing the risk of the crane falling along with the rail. *You can also view experimental materials from the PDF download.
