Introduction
The Northern Drywall Lift allows one person to lift a drywall panel that is up to 4 ft x 16 ft in size, without assistance. The panel
can be raised to a maximum height of 11 ft for attachment to level ceilings — or (with the Lift's cradle tilted) to sloped ceilings or
side walls. For higher ceilings, an Extension Accessory is available that increases maximum lift to 15 ft.
The Lift's cradle lowers to 34 in. off the floor for easy panel loading, and can support up to 150 Ibs.
These instructions explain how to assemble the Lift, operate it, disassemble it after use for easy transport and storage, and
order replacement parts. We urge you to read the Important Precautions below, and the Operation sections, before trying to
use the Lift. |

Operator Controls
Slide Yoke Ring
Press down on the slide yoke ring to unlatch the two forward legs so they
can be rotated out to the Lift's working position or in to its storage position.
A spring-loaded pin snaps into a hole on the bottom of the slide tube, to
lock the folding legs in position.
Backstop
Pivot the backstop down to prevent the base from rolling backward, or up
to allow the unit to wheel freely.
Outriggers
The outriggers on the crossarms extend for supporting a longer drywall
panel.
To extend an outrigger, pull out the lock pin with your right hand until you can
slide the outrigger out with your left hand. The lock pin can engage to lock
the outrigger at one of three positions: fully retracted; extended 21 in.; or
extended 33 in.
IMPORTANT: Never load a drywall panel or operate the Lift if the lock pins
are not engaged at one of these three positions, or if the outriggers are ex-
tended beyond the 33-in. position.
To avoid damaging them, always fully retract the outriggers before trans-
porting or storing the Lift.
Panel Support Hooks
Open the support hook on each crossarm to support the drywall panel when
it is being loaded, or when the cradle is tilted.
To avoid damaging them, always close the support hooks before transport-
ing or storing the Lift.
Slide Bar Lock
The slide bar lock holds the winch assembly at its operating (fully extended)
position.
To fold the winch assembly against the frame (when disassembling the unit
for transport or storage), disengage the lock by turning it counterclockwise
as you lift on the slide bar.
When you reassemble the unit for operation, extending the winch assembly
all the way and then pressing it back slightly toward the frame automatically
engages the lock.

Maintenance
Inspect the cable before each work day. Replace it at the first sign of
wear (refer to the instructions supplied with the replacement cable).
Occasionally oil the cable pulleys. Crank up the telescoping sections
for access to the internal cable pulley. Never allow oil or grease to con-
tact the surface of the winch brake drum.
Occasionally oil the caster bearings.
If the telescoping sections of the frame don't operate smoothly, apply
household paraffin to the sliding surfaces.
Extension Accessory
For higher ceilings, an Extension Accessory is available that increases
maximum lift to 15 ft (instead of the standard 11 ft).
The Accessory consists of two 6-ft telescoping sections that replace the
standard 4-ft sections inthe frame. A longer cable is preinstalled in the tele-
scoping sections, and must be attached to the winch drum.

ASME Standards for wire rope (cable) inspection and replaceme
Reprinted from ASME B30. 19-2000, by permission of
The American Society of Mechanical Engineers. All rights reserved.
19-2.4: Rope Inspection, Replacement and Maintenance
19-2.4.1 General. Sheave diameters, drum diameters and rope design are limited
because of cableway design configuration. Due to these parameters, inspection in
accordance with para. 19-2.4.2 to detect deterioration and timely replacement in
accordance with para. 19-2.4.3 are essential.
19-2.4.2 Inspection
(a) Frequent Inspection
(1) All running ropes in service should be visually inspected once each work-
ing day. A visual inspection shall consist of observation of all rope that can reason-
ably be expected to be in use during the day’s operations. These visual operations
should be concerned with discovering gross damage that may be an immediate haz-
ard, such as listed below:
(a) distortion of the rope such as kinking, crushing, unstranding, bird-
caging, main strand displacement, or core protrusion. Loss of rope
diameter in a short rope length or unevenness of outer strands
should provide evidence that the rope or ropes are to be replaced.
(b) general corrosion;
(с) broken or cut strands;
(d) number, distribution, and type of visible broken wires [see paras.
19-2.4.3(b)(1), (2) and (7) for further guidance];
(e) core failure in rotation-resistant ropes; when damage is suspected,
the rope shall either be removed from service or given an inspection
as detailed in para. 19-2.4.2(b).
(2) Care shall be taken when inspecting sections of rapid deterioration, such as
ange points, crossover points, and repetitive pickup points on drums.
(3) Care shall be taken when inspecting certain ropes, such as rotation-resist-
ant ropes, because of their higher susceptibility to damage and increased deteriora-
tion when working on equipment with limited design parameters. The internal deteri-
oration of rotation-resistant ropes may not be readily observable.
(b) Periodic Inspection
(1) The inspection frequency shall be determined by a qualified person and
shall be based on such factors as expected rope life (determined by experience on the
particular installation or similar installations), severity of environment, percentage of
capacity lifts, frequency rates of operation, and exposure to shock loads. Inspections
need not be equal calendar intervals and should be more frequent as the rope
approaches the end of it's useful life. The inspection shall be made at least every
1000 hr of cableway operation or annually, whichever comes first.
(2) Periodic inspections shall be performed by an appointed or authorized
person. This inspection shall cover the entire length of rope. Only the surface wires
of the rope need to be inspected. No attempt should be made to open the rope. Any
deterioration resulting in appreciable loss of original strength, such as described
below, shall be noted, and a determination shall be made as to whether further use of
the rope would constitute a hazard:
(a) points listed in para. 19-2.4.2(a):
(b) reduction of rope diameter below nominal diameter due to loss of
core support, corrosion, or wear of outside wires;
(c) severely corroded or broken wires at end connections:
(d) severely corroded, cracked, bent, worn, or improperly applied end
connections.
(3) Care shall be taken when inspecting sections of rapid deterioration, such as
the following;
(a) sections in contact with saddles, equalizer sheaves, or other sheaves,
including track cable sheaves, where rope travel is limited;
(Bb) sections of the rope at or near terminal ends where corroded or bro-
ken wires may develop.
19-2.4.3 Rope Replacement
(a) No precise rules can be given for determination of the exact time for rope
replacement, since many variable factors are involved. Once a rope reaches any one
of the specified removal criteria, it may be allowed to operate to the end of the work
shift, based on the judgement of a qualified person. The rope shall be replaced after
that work shift, at the end of the day, or at the latest time prior to the equipment
wing used by the next work shift.
b) Removal criteria for rope replacement shall be as follows:
(1) in running ropes, six randomly distributed broken wires in one lay, or three
broken wires in one strand in one lay.
(2) One outer wire, broken at the contact point with the core of the rope, that
has worked it’s way out of rope structure and protrudes and loops out from
the rope structure, Additional inspection of this section is requ
(3) Wear of one-third the original diameter of outside individual w
(4) Kinking, crushing, birdcaging, or any other damage resulting i
tion of the rope structure.
(5) Evidence of heat damage from any cause.
(6) reductions from nominal diameter greater than these shown bel
Max. Allowable reductio

(Cc) Broken wire removal criteria cited in this volume apply to wire roj
operating on steel sheaves and drums. The user shall contact the sheave, drur
cableway manufacturer, or a qualified person for broken wire removal criteri:
wire ropes operating on sheaves and drums made of material other than steel.
(d) Replacement rope shall have a nominal strength rating at least equa
the original rope furnished or recommended by the cableway manufacturer or
designer, or a qualified person. Any deviation from the original size, grade, or
struction shall be specified by the rope manufacturer, the cableway manufactu
designer, or a qualified person. -
(e) Ropes Not In Regular Use. All rope that has been idle for a period ol
month or more due to shutdown or storage of a cableway on which it is installe
shall be given an inspection in accordance with para. 19-2.4.2(b) before it is pl:
in service. This inspection shall be for all types of deterioration and shall be pe:
formed by an appointed or authorized person.
(f) Inspection Records
(1) frequent inspection-no records required.
(2) Periodic inspection-in order to establish data as a basis for judg
the proper time for replacement, a dated report of rope conditio:
each periodic inspection shall be kept on file. This report shall
cover points of deterioration listed in para. 19-2.4.2(b)(2).
(g) A long-range inspection program should be established and should
include records on examination of rope removed from service so a relationship ci
be established between visual observation and actual condition of the internal str.
ture.
19-2.4.4 Rope Maintenance
(a) Rope should be stored in a manner that prevents damage or deterioration
(b) Rope shall be unreeled or uncoiled as recommended by the rope manu-
facturer, with care taken to avoid kinking, or inducing a twist.
(c) Before cutting a rope, seizings shall be placed on each side of the place
where the rope is to be cut to prevent unlaying of the strands. On preformed rope,
one seizing on each side of the cut is required. On nonpreformed ropes of 7 in. (22
mm) diameter or smaller, two seizings on each side of the cut is required; and for
nonpreformed rope of 1 in. (26 mm) diameter or larger, three seizings on each side
of the cut are required.
(d) During installation, care should be exercised to avoid dragging the rope
in the dirt or around objects that will scrape, nick, crush, or induce sharp bends.
(e) Rope should be maintained in a well-lubricated condition. It is important
that lubricant applied as part of a maintenance program shall be compatible with
the original lubricant, and to this end the rope manufacturer should be consulted:
lubricant applied shall be the type that does not hinder visual inspection. Those sec-
tions of rope which are located over sheaves or otherwise hidden during inspection
and maintenance procedures require special attention during lubrication. The object
of rope lubrication is to reduce internal friction and to prevent corrosion.
(f) When an operating rope shows greater wear at well-defined localized
areas than on the remainder of rope, rope life can be extended in cases where a
reduced rope length is adequate by cutting off a section at the worn end, thus shift-
ing the wear to different areas of the rope.
