5. Warnings and Special Measures
5.1 Special Loads and Overload
5.1.1 Dynamic Loads
All loading criteria used for the design of the Stageline SL100 mobile stage meet or exceed the requirements of American and
European standards. Moreover, when designing our products, dynamic loads generated by the normal operation of a stage were taken
into account, such as lighting and sound equipment movement, winch operation as well as dance or acrobatic performances.
However, some unusual dynamic loads, such as stunt performances on the stage floor or trapeze artists securing themselves to the
structure could be dangerous for the users and the equipment. When special dynamic loads are anticipated, please contact
Stageline beforehand.
Certain dynamic loads may provoke sudden and excessive movements of the floor and roof structures.
This could jeopardize the stage’s stability and the safety of its users.
CAUTION
5.1.2 Additional Load from Peripherals
Standard supports are provided along the floor sides to allow the insertion of floor extensions. The stages are not designed to support
additional vertical and horizontal loads brought on by this peripheral equipment. It is therefore necessary to plan the position of peri-
pheral equipment in such a way as to not add significant loads to the stage structure. If in doubt, contact Stageline.
5.1.3 Prevention of Floor Overload
The SL100 mobile stage manufactured by Stageline is designed to support a uniformly distributed load of 150 lb./sq. ft. (732 kg/m²).
To support this weight, the stage must be in good condition and set up in accordance with the procedure found in this manual. It is
possible to raise the floor capacity of the stage. Please contact Stageline for details.
Taking into account the floor surface, its total capacity is substantial when all the equipment is equally distributed. However, a heavy
load concentrated on a small surface could damage the floor.
Overload occurs when a local curvature of the floor structure exceeds 3/8’’ (10 mm) or a curvature in the plywood between its support
girders exceeds 1/8’’ (3 mm).
If the floor structure is overloaded, it can be supported locally by adding legs. These must be placed underneath the structure girders.
They must also be solidly secured in order not to fall if the stage were to move.
If the plywood floor covering is overloaded, the load must be moved or redistributed on the girders using beams or platforms.
Even if the floor seems to support an overload, this does not necessarily mean that the load is acceptable and safe.
Vibrations or a slight weight addition could cause a sudden rupture.
CAUTION
5.1.4 Rigging Load Management
The SL100 mobile stage manufactured by Stageline is designed with rigging points. The positioning and the load capacity of these
points have been established to allow the highest number of light and sound layouts.
A presentation of all rigging points, their maximum capacity as well as the load combinations permitted can be found in the
Rigging Plan.
Under no circumstances can loads other than those shown be added without prior written approval by Stageline.
CAUTION
In the case of an unusual layout, please contact Stageline and submit a proposed rigging plan before installing any light or
sound systems.
