GENERAL WARNING
Read this general warning first.
In suspended platform operations, safety is a matter of life or death for riggers,
operators and by-standers. This warning is your share of duties for achieving safety.
YOUR DUTY TO UNDERSTAND AND COMPLY.
1. It is the responsibility of the riggers and operators, and their
employer’s responsibility, if they operate under an
employer’s control, to strictly conform to the following
warnings.
2. It is imperative for safety and efficiency of operations
that this manual be read and fully understood by the
rigger and the operator before rigging or operating the
platform. All instructions contained herein must be
carefully and strictly followed, including applicable SAIA
code of safe practices.
3. Should you hand over a skybeam under any conditions, to
any party operating out of your control, you must attach a
clean copy of this manual and draw to other party’s attention
that strictly following all the instructions therein is a matter of
life or death.
4. Before using the skybeam, the rigger and the operator must
become aware of all the requirements of federal, state,
provincial and local safety regulations not only applicable to
the skybeam, but also to the entire suspended scaffold
system or any component of it.
5. Never use the skybeam for any job other than lifting
personnel on suspended scaffold according to the
instructions of this manual.
6. Never load the skybeam above its rated load.
YOUR DUTY TO INSPECT AND MAINTAIN.
7. Keep this manual available at all times for easy reference
whenever required. Extra copies are available through the
equipment supplier.
8. Carefully take notice of all the labels and markings affixed to
the skybeam. Never rig or operate the skybeam if any label,
normally fixed on it, is obscured or missing. Replacement
labels are available through the equipment supplier.
9. Every time the skybeam is to be rigged or used, check that
the skybeam, platform, hoists, wire ropes and other
components of the suspended scaffold system are complete
and in good working condition, prior to proceeding.
10. A careful and regular inspection of the platform hoists, wire
ropes and other components of the installation is part of the
safety requirements. If you have a question, call the
equipment supplier.
11. Before rigging, re-rigging and after, the skybeam must be
inspected by a Competent Person familiar with the skybeam
and professionally trained for the purpose.
12. Inspection by persons authorized by riphoist is to be
carried out once every six months, to spot check the
condition of the beam and its components and that
rigging is being done correctly. A signed and dated
report card should be maintained for these purposes.
13. The manufacturer declines any responsibility for
consequences of repairs or modifications brought out of
its control to the product, specially by replacement of
original parts or repairs by another manufacturer.
YOUR DUTY TO TRAIN AND CONTROL PEOPLE.
Compliance with safety rules extends to rigging
operations which must be carried out only after securing
safe conditions of operation as per safety regulations and
requirements.
14. An operator must not be assigned to a suspended job or
to rigging for a suspended job, or to de-rigging after the
job, if that person is not:
a) mentally and physically fit for the purpose, especially
at heights.
b) competent for the job to be performed.
c) familiar with the scaffold equipment as rigged.
d) professionally trained for working under the above
requirements.
Except for the operations described in this manual, the
maintenance of the skybeam, as well as repairs, must be
exclusively done by repairers authorized by riphoist.
Spare parts used for all equipment must be in
accordance with the product, no substitutions are
allowed.
15. Never let the skybeam or other components of a
suspended scaffold system be managed or operated by
any person other than authorized and assigned to the
job. Keep the equipment, either rigged or unrigged, out of
reach of unauthorized persons, while out of operation.
16. Training operators and riggers includes setting up rescue
procedure should a scaffold be brought to a standstill
during a job. Such procedure must be set up by a
Competent Person or its technical consultant, according
to the working conditions, prior to putting the equipment
into operation.
17. Every suspended job must be placed under the control of
a person having the required competence and authority
for checking that all the instructions prescribed by this
manual be regularly and efficiently carried out.

YOUR DUTY TO SAFETY BEYOND T E ROOFBEAM
As being only one piece of a scaffold system, the skybeam
can contribute to the required safety only if:
18. Compatibility of other brands has been verified & approved
by Tractel® griphoist engineering department.
19. It is fitted on compatible equipment.
20. Other components meet the requirements of the applicable
safety regulations and requirements, are of the proper
quality, assembled to form a safe and efficient suspended
scaffold system, and are approved by riphoist engineering
department.
21. Every upper support of the scaffold is stable, sufficiently
strong and properly tied back to the structure, according to
the load either static or dynamic.
22. The supporting structure and tie-backs are required to
withstand every load to be applied, either static or dynamic,
during rigging or operating the scaffold equipment.
23. All the requirements in strength and resistance are obtained
with the necessary safety coefficients (see regulations and
professional standards).
24. All the calculations, design and subsequent work necessary
to meet the above requirements have been made by a
Competent Person on the basis of proper technical
information regarding the site.
YOUR DUTY TO AVOID TAKING C ANCES.
25. Once the suspended platform has been lifted off its initial
support (ground or any other level), it is imperative not to
release, remove, alter or obstruct any part of the equipment
under load.
26. NEVER allow any condition which would result in a
suspension wire rope becoming SLACK during the
operation unless:
a) the suspended platform is safely supported on a safe
surface giving a safe access to the operator in compliance
with safety regulations.
b) another suspension wire rope has been safely rigged to
the suspension platform.
27. Never operate a platform and its accessories, especially
electric ones, in a potentially explosive atmosphere.
28. For any job to be performed on the suspended equipment,
consider and control the specific risks related to the nature
of the job.
29. Should you decide that this skybeam is no longer to be
used, take precautions in disposing of it so that it cannot be
used any more.
30. The manufacturer declines any responsibility for any
special rigging or structural combinations beyond the
descriptions of this manual.
31. The manufacturer declines any responsibility for any
other use of the skybeam, than described in this
manual.
32. Do not mix and match the 4' reach light skybeam and
the 11’ skybeam components. Only use configurations
as shown in this manual.
AN ULTIMATE RECOMMENDATION
Never neglect means to improve safety. Due to the risks
inherent in the use of suspended scaffolding, it is strongly
recommended that every installation be equipped with
secondary wire rope(s) fitted with a separate fall arrest
system, anchored to a safe separate point of the building
structure.
This manual is neither a regulations compliance
manual nor a general training guide on a suspended
scaffold operations. You must refer to proper
instructions delivered by manufacturers of the other
pieces of equipment included in your suspended
scaffold installation. Whenever calculations and
specific rigging and handling are involved, the operator
should be professionally trained to that end and secure
relevant information prior to commencing such work.
2. TRANSPORT AND ANDLING
andle equipment with care, do not drop equipment
during loading or unloading. Impose loads on the
skybeam gently and without impact.

4.1 ASSEMBLY OF T E 4’ SKYBEAM®
The SKYBEAM must be pre-assembled in accordance with
these instructions. The counterweights are assembled on the
counterweight Frame and all roof loads must be confirmed in
accordance with this manual.
When using casters, install guide channels on structure to guide
the casters. Two channels are required, one for the front
support and one for the rear counterweight Frame. See Fig. 1.
• Block the end of guide channels with end stops.
• Always use a guide channel on roofs to distribute bearing
load.
• uide channels to run parallel to building face.
• Rigidly secure both ends of guide channels to the structure
Determine if you are using the two or three beam version of the
4’ Skybeam. Both have a 4’ reach and a 1,000lb (454 kg)
capacity, the advantage of the three piece beam is less
counterweights are required (16) versus (28) required for the
two beam variation.
4.2 TWO PIECE SKYBEAM ASSEMBLY. (MRB2P)
Ensure you have the correct components for assembly
1 – MRBL0200 Connection Beam (1)
1 – MRBL0210 4’ Front Beam (2)
1 – MRBL0230 4’ Rear Beam (3)
Lie the components on the ground in the following sequence:
Front beam (2) – Connection Beam (1) – Rear Beam (3)
Note: If Using the Optional Sliding Collar (for Horizontal
applications only) (4), slide the collar onto the bottom of
the Front Beam (2) before connecting the unit together.
Then slide the collar behind the front shackle.

4.4 CONTINUED - ASSEMBLY OF ROOF BEAM
Level the outrigger beam and support assembly. Attach the
thimble end of the suspension wire rope to beam using a 5/8",
3-1/4 ton shackle (1). See Fig 10. Once the rope is attached,
set the assembly into working position. For beams with casters,
apply the brakes on all of the casters. Once in position install
taut tieback to the rear shackle (Fig. 13) as shown on Page 16
& 17 Fig. 14 & 15.
Note: The optional sliding collar shown in Fig. 10 is
for suspension only in the horizontal position. It is
not recommended for the inclined suspension beam.
If you are using the two beam version of the 4’
skybeam 28 counterweights are required. The three
beam version requires 16 counterweights. Both
beams have a 4’ reach and a 1,000lb. (454 kg)
maximum capacity.
Add the counterweights (#3348) (up to 32 max.) to the
counterweight beam (See fig 8). Check once again the
maximum admissible load (see Section 4.4 page 17 –
Calculation of counterweight) related to the reach and the
number of counterweights on the counterweight beam. Install all
required counterweights on the counterweight beam by lowering
them over the extension pole, starting with the two inside poles.
Distribute the weight as equally as possible on each side of the
frame. See Fig.12.
When all weights are in place install the locking pin to prevent
removal. See Fig. 13.
Attach the tieback wire rope at the back of the rear beam,
to the rear shackle inside. Always insure the tieback has
equivalent strength to the hoisting rope and they must be
installed without slack. See Fig 13. See Section 4.4 Fig. 11
& 12 for proper tie back instructions.

Formula for calculating COUNTERWEI HT & LEN TH of
back beam,
(La) 4 (La) 4
W = or b =
b W
W = L x a x 4 ÷ b or b = L x a x 4 ÷ W
W = Counterweight in Pounds
L = Load in Pounds (Rated capacity of oist)
a = Reach (from center front frame to the suspension wire
rope in feet)
b = Back Span - (Distance between front frame and
back frame in feet center to center)
4 = Safety Factor
Severe injury or death can result from improper use or
assembly. Assemble in accordance to this manual. Check
and recheck counterweight chart and formula. Minor
changes could cause complete system failure. Consult your
GRIP OIST dealer for additional information.
Counterweights must be a nonflowable material, and they
must be attached to the outrigger beam.
Always use tieback wire ropes capable of holding the full
load.

5.2 CALCULATION OF COUNTERWEIG TS
COUNTERWEIG T FORMULA CALCULATIONS
Provided only as a reference. If you are using the two beam version of the 4’ Skybeam 28 counterweights
are required. The three beam version requires 16 counterweights. Both beams have a 4’ reach and a
1,000lb. (454 kg) Maximum capacity.
Example Calculations:
W= ? L = 1000 lbs.
a = 4 foot b = 11’ 6"
(1000x4) x4
W =
11.5
W = 1391 lbs of Counterweights
(26 pcs.) or more, must be added.
Only have 990 lbs. in Counterweights
then
W= 990 L = 1000 lbs.
a = 4 foot b = ?
(1000x4) x4
b =
990
b = 16’ 2" Therefore the distance
between A and B must be 16 foot and
2 inches or greater.
