Operating Instructions
G1108.3 - 03/2021 US-5
YOUR DUTY TO TRAIN AND CONTROL PEOPLE
(1) 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,
specially at heights,
b) competent for the job to be performed,
c) familiar with all applicable safety rules and
requirements,
d) familiar with the scaffold equipment as
rigged,
e) provisionally trained for working under the
above requirements.
(2) Never disassemble the tirak® by yourself or
by your staff. People’s lives may be at risk.
Except for the operations described in this
manual, the maintenance of the tirak®
hoists, as well as disassembly and repair,
must be exclusively done by qualified
repairers authorized in writing by the
supplier. tirak® spare parts in accordance
with the serial number of each machine must
be exclusively utilized. No substitutions are
allowed.
(3) Never let the tirak® hoist and other
equipment of a suspended scaffold system
be managed or operated by a 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.
(4) 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 of the user, or of its
technical consultant, according to the
working conditions, prior to putting the
equipment into operation.
(5) Every suspended job must be placed under
the control of a person having the required
competence and the authority for checking
that all the instructions prescribed by this
manual be regularly and efficiently carried
out.
YOUR DUTY OF SAFETY BEYOND THE TIRAK
As being only one piece of the scaffold system,
the tirak® hoist can contribute to the required
safety only, if …:
(1) … it is fitted on compatible scaffold
equipment, including the wire rope used in
the tirak® hoist.
(2) … other components meet the requirements
of the applicable safety regulations and are
of the proper quality, and assembled to form
a safe suspended scaffold system.
(3) … 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.
(4) … supporting structure and tie-back provide
the requested resistance to every load to be
applied, either static or dynamic, during
rigging or operating the scaffold equipment;
(5) … all the requirements in strength and
resistance are obtained with the necessary
safety factor (see regulations and
professional standards);
(6) … all the calculations, design and
subsequent work necessary to 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 CHANCES
(1) The blocstop® BSO or blocstop® BS/BSO
secondary brake located at the upper part of
the unit is an integral piece of the tirak®
hoist. It is strictly forbidden to detach it from
the main body of the hoist for whatever
reason. Doing so would be a misuse
creating an extreme hazard and placing
operators and by-standers in danger of
death resulting from the possible fall of the
suspended equipment: scaffold, workcage,
bosun’s chair or any other items or
components.
(2) Once the suspended scaffold, work-cage or
bosun’s chair has been lifted off its initial
