Positioning and/or erecting a telescopic ladder
- A telescopic ladder in ladder position has to be positioned in such a way that the distance
from the foot of the telescopic ladder to the wall is approximately equal to a quarter of the
operational length of the ladder. The set-up angle will then be approximately 75° (figure 1
C).
- Always stand the telescopic ladder on a firm, stable, horizontal surface, which is not
slippery. This will ensure that the feet of the telescopic ladder cannot sink into the ground
and/or slip away. Therefore, do not place the telescopic ladder on tables, boxes, crates or
other unstable surfaces, such as muddy soil or loose sand.
- Position a telescopic ladder in such a way that each of its four points are adequately
supported by a firm bearing surface, therefore never against a window, against circular or
narrow pillars, poles or trees or against corners (figure 1D).
- Satisfy yourself that the telescopic ladder is sufficiently stable and if required, is secured to
ensure it cannot slip.
- A telescopic ladder may never be repositioned if somebody is standing on the ladder, or
from a position that is higher than the ladder.
- Take extra precautions if the telescopic ladder has to be positioned in front of a door
opening, an opening window or in a corridor, etc. Make sure that nobody can walk against
or under the telescopic ladder.
- Never position a telescopic ladder within a range of 2.5 m from non-insulated electrical
components or low-voltage installations and networks which are under live current. Never
position an aluminium telescopic ladder in the vicinity of components of high-voltage
installations.
- Take care when using electrical equipment. Telescopic ladders conduct electric current.
Always take precautions so that a power cable cannot become trapped or become caught
when climbing, sliding or repositioning the telescopic ladder. Check beforehand that your
tool's electrical cable is not damaged.
- Telescopic ladders must always be positioned on their feet and not on the step/rung.
- Always position a telescopic ladder as close as possible to the work to be carried out.
- Do not operate the unlocking catches or the unlocking/locking buttons when someone is
standing on the telescopic ladder (figure 2 C, figure 2 D and figure 2F).
- Visually check that all steps/rungs are locked before climbing the telescopic ladder.
1) In telescopic ladders with manual unlocking (e.g. Tele-Logic 420, Tele-XL 480, TeleClimb,
TeleSmart) this can be checked on the basis of the catches (figure 3A).
2) In telescopic ladders with partially automated unlocked (e.g. Tele-Promatic 420 and Tele-
ProMatic 480), this can be checked through the position of the locking buttons below the
rungs (figure 2 C) and the catches (figure 2 D).
Collapsing and extending a telescopic ladder
Important!
Follow the instructions below closely when collapsing and extending a telescopic ladder.
This will help prevent fingers becoming caught between the rungs and the uneven spaces
in between! A distinction is made between a telescopic ladder in which all rungs unlock
manually (1) and telescopic ladders in which after unlocking the 2nd rung, the other rungs
are unlocked automatically (2.)
Relax. It's an Altrex.
