HEADER-BRACED RUNWAY
Service Crane top running header-braced overhead crane systems are self-supporting and work well where minimum floor obstructions are essential and the lowest obstruction in the building is high enough for the system to be installed while still giving adequate headroom (hook height).
A main component of a top running header-braced crane runway system is a top running bridge crane designed with the bridge on the top of the runway. No knee braces are required, increasing valuable production space. The runway is supported by the freestanding support columns each pair tied together by a header. Stand alone workstation bridge cranes do not rely on building or support column integrity. Header-braced systems are ideal when the lowest obstruction in the building is high enough that it does not limit the hook height.

- Bolt together construction allows for easy installation, relocation, and expansion
- Professional engineers approve all system drawings
Multiple Cranes Sharing the Same Runway
To maximize use and flexibility of production space and to safely lift long and awkward heavy loads, use multiple overhead cranes of different capacities on the same runway. For example, a 20 ton runway can be used to support two 10 ton bridge cranes with no mechanical or electrical separation devices. As well as, a 10 ton runway can be used with two 10 ton bridge cranes utilizing mechanical devices such as buffers (bumper extensions) or electronic separation devices, limit switches or load limiters. These optionally equipped, load summing cranes will shut down when they determine that the total load exceeds the overall capacity of the runway.
