BMK CLIMBING BRACKETS
5. SYSTEM PROPERTIES
5.1. MAXIMUM SIZE OF FORMWORK PANEL
The system is designed to work under the following conditions:
Notes:
 The maximum wind load is 0.2 kN/m² which corresponds to a wind speed of 64 km/h.

For wind speeds above 64 km/h, all activities on the climbing structure are abandoned and the workers leave
the platforms. Moreover, it is necessary to move the formwork towards the wall and block the roll-back
carriage with the Gear Locker MK (1991510) (see for details on page 16).
One limit of the climbing bracket BMK structure is relates to the maximum size of the formwork panel.
In the below chart, the relation between panel height and width of the climbing bracket BMK-240 is shown. It is
assumed that the length of the working platforms and the formwork panel width is the same.
This chart is valid only for a working height below 100m.
