Overhead Crane Systems
Ergonomic Partners can help with your overhead bridge crane early in the project by developing a specification for the right type of equipment, and working with the building architects to assure it will fit in your building and provide the proper operation. Too many times a bridge crane is an afterthought and vital items such as hook height, and floor coverage are sacrificed due to poor planning. We can provide top running bridge cranes as follows: Single Girder Top Running Bridge Cranes-Up to 20 ton capacity/120 foot span and Double Girder Top Running Bridge Cranes-Up to 100 ton capacity, 150 foot span.
Typically top running overhead systems are used in applications that are more demanding, especially double girder top running bridge cranes. We can provide overhead bridge cranes to go into clean rooms, explosive environments, molten metal handling and other demanding environments. If a typical bridge crane is not what will fit your application we can provide cranes such as single and double leg gantry cranes. Whether you need manual, electric or air powered bridge crane we can provide a solution. In addition to the bridge crane, we can provide the runway structure to work in conjunction with a new building or an existing building.
- Completely Freestanding (very good for existing structures or light metal buildings) for top or under running design overhead cranes
- Freestanding but tied back to the building structure-(in buildings with some substance-new or existing buildings) for top or under running design bridge crane.
- Suspended from your building (typically new buildings)-under running design overhead bridge crane
- Set on haunches (typically new building construction)-top running system
All runways are designed per CMAA, ANSI and AISC specifications and are designed by a professional engineer. These runways can be stamped by a professional engineer. If you are looking at an under running bridge crane we recommend a patented track system from TC/American.
