|
 |
Surface
Mount:
The platform deck is
5” from the floor on the
ground level and flush with
the floor on upper level. |
|
|

|
|
 |
|
|
|
Note:
Dimensions and calculations
shown are for reference purpose only
and may differ from your lift. Before
making any building modifications,
contact us to request a job-specific
drawing. Some limitations may apply. |
|
|
|
|
|
|
|
STRUCTURE
Guide rails are constructed from structural steel H-Beam.
Carriage uses steel channel for vertical members and
header. Carriage deck (platform) is built from solid
steel plate on a square steel tube frame. |
SAFETY
SYSTEMS
Fail-safe electric brake locks the carriage in place in
the
event of a power failure. Slack cable switches shut off
the motor if the cables become slack. Broken cable brakes
prevent the carriage from falling in the unlikely event
of
a cable failure. Limit switches provide accurate leveling
at each level. “NO RIDER” signs are on carriage
and
at each entry point. Double swing interlocked gates
prevent access to the carriage while in motion and
when not present at that level. |
|
|
|
|
OPERATION
Illuminated push-button stations at each level allow full
call/send capabilities, inform the operator of carriage
position and indicate door open. Mushroom style
E-Stop buttons are included in every call station. |
|
|
|
|
|
|
|
|
|
|
|
MECHANICAL
DRIVE
The carriage is moved by using an electric failsafe
brake motor and reducer. Dual cables and drums
provide extra safety and durability. This drive system
requires very little maintenance. Electric brake motor
prevents carriage drift. |
|
CARRIAGE
Carriage is built as one piece for added strength. Platform
panels are provided on non-operating sides of the
carriage and snap chains on operating sides for safety. |
|
|
|
|
ELECTRICAL
Control voltage is 24V for all switches and momentary
push button stations. Push button stations are
NEMA 12. |
|
|
|
|
|
|
|
SECURITY
ENCLOSURES (OPTIONAL)
Panel and gate frames are constructed from steel angle
covered by 1/2” expanded metal. These enclosures
provide a means of protecting personnel from entering
the path of a moving lift. Double swing interlocked gates
prevent access to the carriage while in motion and when
not present at that level. |
|
|
|
|
Note:
To comply with ANSI/ASME B20.1 standard, proper
guarding on all accessible sides must in place during
operation.
This is usually achieved by building a sheetrock/drywall
shaft
or using optional enclosures. Our lifts are not subject
to elevator
codes as they are designed for material lifting only.
No personnel
are permitted to ride on vertical lift. |
|
|
|
|
The
following items are to be supplied by others and are not
included with the vertical lift:
(1) wall and floor hardware to secure the lift to the
walls and floors,
(2) external electrical wiring which is to be performed
by a qualified electrician to local and
national codes,
(3) the conduit and disconnect switch that is required
to connect our control panel and
(4) upper and lower thresholds. |

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
A.
Prior to commencing installation of the VRC, the installer
shall visually examine the conditions under which
the VRC is to be installed and notify the architect in
writing of conditions detrimental to the proper and timely
completion of the work. |

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
A.
Installer must comply with manufacturer's detailed mechanical
and electrical installation instructions for proper
installation and to meet safety codes. All thresholds
and extra installation materials needed must be supplied
by the installer. |

FIELD QUALITY CONTROL |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
A.
Inspection: Upon completion of installation, the VRC shall
be inspected to verify that it meets all
requirements set forth by CIP and Parts 1, 2 and 3 of
this Section. |
|
|
|
|
|
|
|
|
|
|
|
|
B.
Tests: |
|
|
|
|
|
|
|
|
|
|
|
|
|
1.
Operating Load Test: The owner will provide a _______
pound test load and load the VRC at the lowest
level. The loaded VRC carriage shall be conveyed to an
upper floor level and returned to the lowest level to
assure proper operation. If the VRC cannot lift or lower
the load, the VRC shall fail the test. |
|
|
|
2.
Performance Test: This test is to be performed in conjunction
with Test 1 above. During the demonstration
of the lifting and lowering test, the owner shall measure
the time required to lift and lower the capacity load.
The owner will average times for lifting and lowering
the load and calculate the average feet per minute travel
speed. If the VRC does not lift the load within 10% of
the specified speed, or if the lowering speed exceeds
the lifting speed by more than 10%, the VRC shall fail
the test. |
|
|
|
3.
Stationary Load Test: This test is to be performed in
conjunction with Test 1 above. The loaded VRC
carriage shall remain stationary at an upper level for
a minimum of one (1) hour. After the one (1) hour period,
the VRC will be inspected for deflection of the components
or drift of the platform. If deformation or downward
drift is evident, the VRC shall fail the test. |
