Typical Hydraulic Rail Clamp
Basic Design includes Manual Release
Rail Clamp Selection
The rail clamp must be chosen according to exposed surface areas of structures and maximum wind speed in addition to a suitable safety factor. For more complicated structures please consult Johnson Industries and we will calculate and recommend the correct rail-clamp for your application.
Serrated Tool Steel Shoes are standard
Smooth shoes for dynamic service
