1-12 Sun Fire 15K/12K Systems Site Planning Guide • June 2003
1.5 Cabinet Floor Caster Weight Load
The cabinet has a concentrated load weight of 628.0 lb (285.5 kg) per three-inch
caster (within the allowable load for a typical computer room raised floor). Review
your facility floor weight requirements prior to moving the Sun Fire 15K/12K
system to its new location.
Note – When lowering the cabinet leveling feet, extend each leveler at the base of
each corner with an additional 1/4 turn to ensure stability for the cabinet. The
levelers should
not raise the casters off the floor.
You can have various loads on a floor: static (concentrated, uniform, ultimate) or
dynamic loads (rolling, and impact). Typical floating floors can handle
approximately 1000 lb (454.6 kg) of concentrated load, 250 lb (113.6 kg) of uniform
load, 2500 lb (1136.4 kg) of ultimate load, and 1000 lb (454.6 kg) of rolling load.
These loads are estimates applied to a one-square-inch area. Review
TABLE 1-3
for the
Sun Fire 15K/12K systems information on pounds per square foot on a building
structure.
Note –
The Sun Fire 15K/12K systems require a shared-aisle space of 4.0 ft
(121.9 cm). For the foot print weight, only unit dimensions and weight are
calculated. For system-shared aisles of 4.0 ft (121.9 cm) (see
FIGURE 2-3
), assume two
48.0 in. (121.9 cm) tiles are at the of front and rear of the system with a weight
allocation of 50% for each system.
There are also tiles such as ConCore2500 from Tate Access Floor Systems, Inc., that
can take up to 2500 lb of concentrated load. If you have any questions concerning
the structural capabilities of any floor, contact a qualified structural engineer.
