CAMCAST
is a strong and durable full overcast system that provides
excellent air tightness even in high water gage. Easily
transportable, the CAMCAST can be assembled quickly
without special tools or heavy lifting.

Features include:
- Construction:
12 gage galvanized steel planks having 2-1/2"
x 6-1/2" trapezoidal corrugations, top and sides.
-
Sizes: Per mine requirements - Virtually any size
available.
-
Strengths and Stiffness: Free span
steel planks are lapped and bolted on 2' centers using
plated fasteners. Safe allowable load on 20' span
is 50 PSF. Well in excess of MSHA requirements...
without beams... and without spreading or separating.
-
Air tightness:
seal strip is sandwiched and compressed between adjacent
planks with plated fasteners. Camber closure # 101-2,
or precast concrete closure seal the ends.
-
Clearance:
Planks are only 2-1/2" deep on top, 2-1/2"
wide per side. This means CAMCAST can be run under
brows eliminating the need for costly and time consuming
headwalls even in low coal. Greater cross sectional
area for ventilation is achieved as well.
-
Resistance to Bottom Hoove:
CAMCASTS are intended for installation without concrete
footers or base channels. Bottom hooves around 2-1/2"
walls rather than up against wider construction.
-
Handling, Transportation and Storage:
Planks nest. Therefore several CAMCASTS can be loaded
on one supply car.
-
Erection Time: 4-men... Less than
one(1) shift.
Camber
Steel Plank Overcast Tops
Camber
Steel Plank Overcast Tops allow clear spans
between masonry walls up to 24' and provide
a solid, long term method of ventilation construction.
Camber exclusive Air Seals make assembly easy
with the highest degree of air tightness of
any method of overcast construction. Steel Plank
Overcast Tops are reusable and the 26"
wide pieces are stackable for efficient transportation
in the mine.
Support walls can be constructed from conventional
masonry or Camber provides the CAMCAST in "all
steel" construction.
