SERIES
FOUR POST VERTICAL LIFTS
|
|
|
For
Heavy or
Bulky Loads
|
|
|
Four
Post style material lifts are designed for moving large heavy
loads and are
constructed from structural steel. These lifts utilize two (2)
100% duty-cycle brake
motors mounted at the top of the unit. The low noise all-mechanical
dual-drive
system safely transports the carriage and the load with ease
by means of four
(4) lifting cables. This style of lift is most commonly used
in large warehouses and
distribution centers for efficiently moving product between
two or more levels/
floors. These lifts require very little maintenance and have
increased longevity
over hydraulic lifts. |
|
 |
|
|
|
|
|
|
All
cable operated lifts are equipped with broken cable brakes to
prevent the
carriage from falling in the unlikely event of a cable failure.
Mechanical interlocks
prevent doors from being opened when the carriage is not present
at that level.
Dual electric brake motors secure the carriage in the event
of a power failure and
prevents the platform from drifting. |
|
|
|
|
|
The
carriage is available in three load pattern configurations:
C, Z & 90. Standard
units have 48”H expanded metal platform side panels on
all on operating sides
and a snap chain across the access sides. Higher panels are
available. |
|
|
|
|
|
Operation
is controlled by a Call/Send Station mounted next to each door
at each
level. Each station is also equipped with a large E-Stop button
to stop the unit in
an emergency. |
|
|
|
|
|
Guarding
around the lift is required to meet safety codes. We offer metal
enclosure
panels and gates to meet your applications requirements. Different
options are
available for shaft installations. Safety enclosures are built
into the structure adding
rigidity and enhanced security. These enclosures are manufactured
from 2” angle
for the framing and covered with 1/2” expanded metal to
reject a 2” diameter ball
as required by code. |

Note:
Dimensions 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 and inform the operator of carriage
position and notify of doors open. E-Stop buttons are
included in every call station. |
|
|
|
|
|
|
|
|
|
|
|
MECHANICAL
DRIVE
The carriage is moved by using two electric fail-safe brake
motors and reducers. Quad cables and drums provide
extra safety and durability. This drive system requires very
little maintenance. |
|
CARRIAGE
Carriage is usually built as one piece for added strength
unless platform size is 8’W or 8’D and larger. Platform
panels are provided on non-operating sides of the
carriage and snap chains on operating sides for safety. |
|
|
|
|
|
|
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. |
|
ELECTRICAL
Control voltage is 24V for all switches and momentary
push button stations. Push button stations are
NEMA 12. |
|
|
|
|
|
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. |

EXAMINATION |
|
|
|
|
|
|
|
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. |

INSTALLATION |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
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. |
|
|
|
|
|
|
|
|
|
|
| 3.03:
FIELD QUALITY CONTROL |
|
|
|
|
|
A.
Inspection: Upon completion of installation, the VRC shall be
inspected to verify that it meets all
requirements set forth by us 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. |
