STRUCTURAL CAPACITY
Safety must be first in all planning for the
installation and operation of the elevator.
This elevator is designed to safely support its
own weight and withstand winds up to 100
mph [160 km/h] for the height specified when
properly guyed. It has not been designed
to support or brace other equipment.
ALL
DISTRIBUTORS, CLEANERS, AND/OR
SPOUTING MUST BE APPROVED IN
WRITING BY MFS/YORK/STORMOR WHEN
SUPPORTED OR BRACED FROM THE
ELEVATOR. OTHERWISE THE EXTRA
ATTACHMENTS MUST BE INDEPENDENTLY
SUPPORTED OR BRACED.
ELEVATOR LOCATION
The elevator must be properly located to receive
the incoming material and discharge it at the
desired location. This requires an exact location
for the boot. Determine whether the boot is to
be fed from the down leg side, the up leg side
or both sides of the elevator. The down leg side
is recommended for light materials like ground
feed. The up leg side is recommended for
heavier free flowing materials like whole grains.
The discharge height should be such that the
spouting is at a minimum slope of 45º
for whole
grains. Contact MFS/YORK/STORMOR for
specific recommendations on other materials.
On outside installations, check the planned
location for the boot, head, spouting, and
guy cables for clearance to other structures.
Driveways, overhead power lines, and building
structures can present special hazards and
obstructions.
On inside installations, check the location for the
leg as it passes through each floor. Additional
clearance for the ladder must be provided
through each floor.
BOOT FOOTING AND PIT
Enough area on the ground must be provided
to adequately support the weight of the elevator
and cable reaction loads in high winds.
Table 1
shows footing loads for each model and height
of elevator. Consult a local Structural Engineer
for a properly designed boot footing.
If the boot is installed in a pit, or other permanent
structure, adequate clearance must be provided
to service the elevator. Of prime concern is
the removal of the boot pulley and use of the
clean-out door. On outdoor installations the pit
will require a sump pump or drain.
