NOTE:
1) Rated loads are to be equally
distributed across the center
of the platform at least 6’6”
(2 meter). Rated loads in the
above table are determined with hoist
capacity at 1000 lbs (450 kg) each.
All platform configurations must use
two hoists as primary suspension
system.
Combined weights of occupants,
debris, blasting grit, tools, equipment
and any other materials etc carried by
the platform are considered as part of
the platform rated load. Platform
rated load plus self weight shall not
exceed total rated capacity of the two
hoists.
2) The above platform configurations
and the corresponding rated loads
are only applicable in Ontario,
Canada.
Any other intermediate stirrup
platform configurations not listed in
this table must be consulted with
Tractel for their project specific
requirements.
3) Platforms longer than 12M (39.5 feet)
meeting Ontario Regulation rated
load design requirements as project
specific use are available, please
contact us for details.
4) The recommended intermediate
stirrup mounting dimension for 2M
and 3M platform modular sections is
10” (254 mm) from the section’s end
but not over 12” (305 mm). Note that
Ontario Regulation limits the stirrup to
be mounted no more than 17.75”
(450 mm) from the ends of the
platform. When project requires
platform sections overhang more than
this limitation or application with
corner modular section, please
contact us with your site specific
requirements.
