Performance and Safety Rules
21- Never load bridges or motorized units beyond their rated capacities. Overloading may
bring damages to equipment or cause the installation to become unbalanced, leading to
serious injury or death.
22- Contact the distributor/service center for service, repair or technical advice. Refer to
equipment type and serial number when calling.
23- Each person must access the platform using a safe means of access such as an optional
access stairs, a transport platform system, stairways or through an opening in the building.
In all cases, transfer must be safe and free from obstruction.
24- The use of appropriate fall protection equipment is mandatory when modifying plank
confi guration or whenever the worker is exposed to a fall hazard. Failure to use fall protection
equipment can expose the user to serious injury or death. Refer to local regulations for
more information.
25- When the motorized unit is moving, it is mandatory that all workers except the operator
stand in an area close to the rear guardrails.
26- In the event of an abnormal occurrence or operation which could compromise security
(ex. malfunction of a motorized unit component, collision with an obstacle, etc.), immobilize
the unit and inform the competent person.
27- It is strongly recommended not to touch any of the moving parts on the motorized unit when
it is in use.
28- All access doors and panels on the motorized unit must be closed when they are not in use.
All access doors and panels must be free from any material or obstruction.
29- The motorized unit must not be used or operated during an electrical thunderstorm. The
motorized unit and its components must not be used as ground for electrical connections.
30- The deposit of loads on the setup must be done with extreme care and under proper supervision.
Loads must be distributed on all the bridges of the setup, as prescribed by the load capacities
charts. Refer to the Load Capacities section on p. 94 for more information about placing
loads on the platform. When the motorized unit setup is not in use and above base level,
loads should not be left on the platform except for counterweights. When a tied installation
is not in use, it is mandatory to leave the platform between two tie levels.
31- On a setup using an F2 Series electrical unit, it is important to note that in the event
of a power outage, it is recommended that all workers remain on the platform as a
safety precaution until the power is restored. If the power has not been restored within a
reasonable time, the emergency descent system must be used to bring the workers safely
back to the nearest safe evacuation point. Refer to p. 43 of the Safety Devices section
for more information on the use of the emergency descent system.
WARNING - WIND SPEEDS
The erection and dismantling of a motorized unit setup (including the base, the
bridges, the masts, the mast ties and all the other components) must not be conducted
when wind speeds exceed 28 mph (45 km/h). Freestanding installations and
setups equipped with weather protection, when allowed, must not be used with
wind speeds exceeding 28 mph (45 km/h). Weather protection, when allowed,
must not be used when work is performed on an open air structure. A motorized
unit setup with mast ties must not be operated when wind speeds exceed
35 mph (56 km/h). If wind speeds are expected to exceed 102 mph (164 km/h),
the motorized unit must be brought down to base level.
When a freestanding installation is not in use:
• The motorized unit must be brought down to base level
When a tied installation is not in use:
• It is mandatory to leave the platform between two tie levels
• All loads must be removed from the setup, except all counterweights applied on
the setup
