C
SERIES - CANTILEVER VERTICAL LIFTS
|
|
Our
Most Versatile Lift
|
|
|
|
 |
|
Cantilever
style material lifts are designed to work in low overhead
areas and are constructed from structural steel utilizing a
100%
duty-cycle brake motor mounted at the top of the unit. The low
noise
all-mechanical drive system safely transports the carriage and
the load
with ease by using dual or quad lifting chains. Our quality
design
provides a reliable means for moving material to a mezzanine
or
multiple levels/floors. These lifts require very little maintenance
and
have increased longevity over hydraulic lifts. |
|
|
|
All
chain operated lifts are equipped with a broken chain brake
to
prevent the carriage from falling in the unlikely event of a
chain
failure. Mechanical interlocks prevent doors from being opened
when the carriage is not present at that level. An electric
brake
motor secures 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
side(s).
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. |

CIP Vertical Reciprocating
Conveyors (VRCs) are
designed to meet or exceed
ANSI/ASME B20.1 Safety
Standards for Conveyors.
Proper guarding and installation
are required in order to meet
local, state and national
codes. Contact us
for more details. |
|
|
|
|
|
|
|
|
|
|
|
|
|
 |
Surface
Mount:
The platform deck is 6”
or 8” from the floor on the
ground level and flush
with the floor on upper
levels. |
|
|
Pit
Mount:
Platform deck is flush
with the floor on all levels
(standard pit is 6”-8”). |
|
|
 |
|
|
|
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
Mast is constructed from structural steel tube. Carriage
uses steel channel for vertical members. 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 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. |

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 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. |
|
|
|
|
|

|
|
|
|
|
3.04:
ADJUSTING AND CLEANUP |
|
|
|
|
