BMK CLIMBING BRACKETS
6. TERMS AND CONDITIONS OF
USE
The general terms and conditions of use can
vary. Therefore, those are defined for each application
in particular and included in the documentation for
each project.
Herein, serving as example only, the general terms
and conditions of use are outlined.
6.1. LOAD CASES
The following load cases are identified for the
climbing brackets BMK:
 Working case: when carrying out works such as
concrete pouring, placing steel reinforcement,
preparation and stripping. These works are
restricted to a permissible wind speed of 64 km/h
(0.2 kN/m
2
).

Out-of-service case (OS): when wind speeds are
above the maximum permissible wind speed of 64
km/h (0.2 kN/m 2 ).
When facing an out-of-service situation, the
following preventive measures must be taken to
ensure the safety of workers on the building site:

Evacuate all employees working on the climbing
bracket structure. Works must not continue on the
climbing formwork.

Tie any loose object of the climbing platforms.

In an out-of-service situation, the formwork panels
are moved against the wall and the stripping
systems blocked.
6.2. MAXIMUM WORKING LOADS
According to the load case, some maximum load
conditions are specified to which the system can be
submitted.
In each load case, permanent loads equal for all load
cases and variable loads differing according to the
load case are considered.
Subsequently, the loads to consider are specified:

Permanent loads:
o
Self-weight of the structure
o
Self-weight of the formwork panels
o
Self-weight of the working platforms

Variable loads:
o
Live loads on working platforms
o
Wind loads (according to Eurocode 1)
The final values are specified in the
documentation of each application.
Serving as example, these are the loads to consider.

According
to EC-1
(parts 1-
4).
The customer is responsible to check the wind
speed and the live loads on the platforms at all times.
