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.

Surface Mount:
The loading height is 6” or 8”
from the floor on the ground
level and flush with the floor
on upper levels.

floor on all levels (standard
pit is 8" - 12”).
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.
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.
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.
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.
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 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.
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.
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.
