Arch
Supports
Structural steel arch supports and circular
ring sets are used for roof support or ground
control where severe conditions are anticipated
or to maintain critical areas of a mine
or tunnel where roof bolting or cribbing
is not sufficient or practical. Used in
conjunction with Camber Lagging systems,
arches can solve difficult conditions on
a long-term basis.

Clearance Rectangles
for Arched Entry Support Layout
X2 Y2 is the height and width of the highest

X1 Y1 is the height and width of the widest
piece of equipment
Arch
supports range from almost rectangular shapes,
to semi-circles, to Gothic shaped structures.
Each has design advantages and disadvantages
depending on the application.
Some of the standard configurations are
shown to the right, however the best approach
is to determine your specific needs and
layout a support around your specific criteria.
We take into consideration your requirements
as far as clearances, load capacity, handling,
and other site specific issues and provide
an arch to best fit your needs.
