BMK CLIMBING BRACKETS
 The Lifting Hook MK must be visually checked
before each use and removed from service, if not
working properly.

If the Lifting Hook MK experiences any sort of
deterioration during handling, it must be
immediately removed from service.
 Before starting to lift the climbing brackets or
platforms, make arrangements to close the sides of
the platform to avoid falls from height.
 No workers are allowed on the working platforms
during their lifting.
 Ensure a steady and smooth travel of the climbing
structure. Avoid any sudden jerky movements.

Step back when lifting starts. Slightly lift the item
and check that the load is balanced and secured
correctly.
 If not, lower the load again to the ground and
revise deficiencies.

Stand clear of suspended load. Do not guide
suspended load with your hands. To guide
suspended load, auxiliary means such as ropes
previously tied to the load are used.

Under the circumstances that the crane operator
has no visual control of the entire trajectory of the
load, the crane operations are guided by a
banksman who is in constant communication with
the crane operator by means of a previously agreed
sign code.
 To prevent collision between platforms or brackets
during elevation, special attention must be paid to
the interferences between platforms and to any
object which could interfere in the elevation
movement of the system.

The entire structure with its components must get
assembled according to the instructions and
assembly drawings provided by ULMA. All bolts,
connections, tie rods, pins, etc. must be assembled
correctly.
 All working platforms of the climbing system are
kept free from ice and snow, even when not in
use.

The maximum permissible wind speed for working
on the climbing system is 64 km/h (0.2 kN/m
2 ). The
customer is responsible to check the wind speed at
each lifting operation and to evacuate the
platforms and to fix all platform components the
way they do not fall down, when wind speed is
rising.

For correct handling of the climbing system, the
customer shall ensure at all times a minimum
lighting of 100 lux in working areas, and
particularly in areas where the cylinder operation is
supervised.
 In the out-of-service case, all employees working
on the climbing bracket structure must leave the
platforms. The formwork panels must be moved
against the wall and the climbing brackets fixed.
 Before moving the roll-back carriages of the
climbing brackets, ensure that nobody remains
between wall or steel reinforcement and formwork
panel.
 The moving of the formwork panel towards the
wall must be carried out with special care. Moving
the panels against the part of the concrete wall
from the previous pouring stage, can cause a pre-
stressing or overloading of the climbing system
hence loading the climbing structure mainly the
screw jacks but also the anchors.
 When moving the formwork panels against the
wall, it is very important to strictly follow the steps
indicated below:
o
Move the panel close to the wall (2-3 cm
from the wall) with the roll-back carriage.
o
Plumb the formwork panel with the push-
pull prop.
