1. I need chocks with additional height
There are three options if additional height is required in your installation:
When additional height is required in the range of 5-25 mm, we can supply taller top rings for the RotaChock® BasicLine/SlimLine/Mounting plate. These can replace the ones originally supplied and provide additional height. We stock these taller top rings for the full range at several thicknesses for maximum flexibility.
If required, a spacer ring can be placed underneath the RotaChock® BasicLine & SlimLine and the foundation.
We stock these Spacer Rings for the full range of several thicknesses for maximum flexibility.
For specific applications, we recommend using the RotaChock® Tall Line, which has an extended bottom ring. However, there are some considerations for using Tall Line configurations, i.e., when thrust or shear forces are involved.
As a rule of thumb for all three options: the height of the chock should never exceed the diameter. For example, the maximum height of the RC4-BasicLine, which is 102 mm in diameter, should not exceed 102 mm. Maximum height = 53, which means that the maximum allowable additional height is 49 mm. From a design viewpoint, the best option is A. The number of mating surfaces should be minimized because this influences the final clamping force.
