Have you completed your earthquake preparedness measures? It reduces the risk of crane falls!
【Crane Gripper】 This is a derailment prevention device for overhead cranes. It slides along the running rails by gripping them from both sides with claw-like components, making it difficult to detach from unexpected external forces. It prevents derailment and sudden drops caused by bouncing during earthquakes or operational errors. It is recommended for earthquake countermeasures. It can also be installed on existing cranes. There are two types: a welded type that attaches to the tip of the saddle and a type that is bolted between the wheels. 【Rail Keeper】 In fact, one cause of crane drop accidents is the hook bolt. Please check how the rails in your factory are secured. If they are secured with hook bolts, we strongly recommend replacing them with rail keepers. Rail keepers can utilize the existing holes of the hook bolts, which reduces the cost of replacement work compared to additional reinforcement with welded fastening devices, and there is no concern about fire hazards.

basic information
We provide easy-to-understand advice for customers installing ceiling cranes for the first time. There are various types of ceiling cranes, and we will offer guidance from the planning stage on how to determine specifications. We also have CAD data for various cranes, including single girder and double rail girders, ranging from 500 kg to 10 tons, so please feel free to contact us if you need CAD data. Additionally, we have digitized all the necessary information for structural calculations, including crane self-weight, maximum wheel pressure, and wheelbase for our standard products, allowing us to provide quick answers. In particular, our specialties include "clean room specification cranes," "HACCP-compliant cranes," "independent cranes," and "automated control cranes." We have standardized independent cranes as well, and we have digitized not only the strength calculations for the steel frame but also the column base reaction forces.

Applications/Examples of results
Since the Great East Japan Earthquake, we have numerous installation achievements on existing cranes. Although it is not widely known, there have been instances of overhead cranes falling during recent earthquakes, which led us to produce this catalog.

Company information
We have delivered cleanroom-spec hoist cranes to various industries such as semiconductors, electronics, precision machinery, film, optical equipment, and food factories, accumulating extensive experience and achievements while refining our technology. Additionally, we have standardized unit cranes using independent running frames for customers who had given up on installing overhead cranes due to structural issues with their buildings, such as rental warehouses, rental factories, and prefabricated structures. Calculating the column base reaction force is essential for determining the column fixation method, and we can respond to these calculations promptly. We have also prepared a demonstration unit for automatic control cranes.
