SPECIFICATIONS
 | All covers and frames are manufactured from grade
T220 cast iron (minimum) to conform to AS 1830 - 1976. |
| Castings are machined to form a gas and watertight
seal. |
| Once assembled, all units are coated in a
bituminous paint complying with BS3416 type II |
| All of Mascot's covers are manufactured in
accordance with the Australian standards requirements for quality
assurance, AS3902 |
|
GENERAL
| Mascot's range of gastight covers are available to
suit all load conditions. From pedestrian traffic, through to
commercial passenger aircraft. |
| Load figures as defined by the National Association
of Australian State Road (N.A.A.S.R.A), have been observed during
the design of products for road and highway application. |
| All "clear opening"
dimensions are quoted as the distance between the leading edges of
opposing frame members. |
|
STANDARD FEATURES
| All frames are designed to provide maximum
resistance to deflection once installed. |
| Mascot covers are manufactured with a special
ribbed design to provide exceptional strength characteristics under
all conditions. |
| All covers are fitted with four keyholes designed
to resist disengagement thereby yielding safer handling. To
prevent the ingress of foreign matter, keyholes are provided with
capping plugs. |
|
MODIFICATIONS AVAILABLE
| HOLD-DOWN BOLTS
For security purposes or to prevent uplift, covers
can be fitted with hold-down bolts. Unless otherwise
requested, bolts are high tensile steel with socket head, removable
by use of allen key. |
| LOCKING COVERS
Single trench and multi-part cover systems are able
to be fitted with a keyed deadlock.
This feature can be provided where the prevention of the removal of
covers or unlawful pit access is of paramount importance. This
is particularly useful for correctional institutions, or pits where
internal access could be gained from outside the building. |
| COUNTER-BALANCED COVERS
For the purpose of quick access, entry or exit,
Mascot's covers can be counter-balanced thereby greatly reducing the
instantaneous lifting effort required.
|
| ANGLED, CIRCULAR, SPLAYED OR INTERSECTING trench
runs can be provided to suit almost all load
requirements. Our technical staff can assist you during
the planning and construction stages with helpful advice on how to
prepare the area for the best, most accurate effect.
