HYDRAULIC WINDSHIELD SYSTEM HWS

ANCHOR BRACKET LIMITATIONS
For each application, the loads to be supported by the brackets must be analyzed. This load analysis should include dead
loads, live loads and wind loads:
The bracket strength will depend on the following factors:
Concrete strength
Cone DW15/M24, DW20/M30 strength
Tie rod DW15, DW20 strength
Bolt M24, M30 strength
Anchor length
Edge effects
Accordingly, bracket limits will vary in each case and a proper study should be carried out. In any case loads
MUST
NEVER
exceed the following values:
This graphic is also valid for the working loads of the “Wall Bracket LT HWS (1991190)”.
The “Anchors” must be placed according with their specifications, in order to assure the correct transmission of
the loads. Only ULMA original components must be used to withstand the structure.
