Safety Instructions; Description Of Operation; Description/Technical Data; In General - Pfeifer Polytex Traducción Del Manual Original

Examples of applied national regulations and standards
for application, use and testing as well as rules for
health and safety when using attachment devices:
• Germany: DGUV Rule 100-500 (formerly BGR 500)
Operation of work equipment (DGUV=German
Statutory Accident Insurance)
• Austria: AMVO (Work Equipment Regulation)
• Switzerland: FCOS guidelines
• or similar

4. Safety instructions

Serious accidents can occur resulting
in injuries or even death if the safety
instructions are ignored!
• The working load limit of the attachment device must
not be exceeded. This depends on the rigging
method, see Chapter 6 Description/technical data.
The safe working load (SWL) always refers to the
„single direct" rigging method.
• The lifting straps must be free from defects and
damage.
• Due to the elongation, only attachment devices of the
same type may be used, e. g. two lifting straps with
the same material property, e. g. polyester (PES).
• Nobody must be inside the danger zone or under the
suspended load during the lifting procedure.
• An expert and the manufacturer must be consulted when
using the lifting straps in conjunction with chemicals,
acids, alkalis or other aggressive substances. The
following information must be available: Type of
chemicals, concentration, temperature and dwell time.
Clarify a possible cleaning procedure with a qualified
person or the manufacturer before and after cleaning.
• Lifting straps with fittings and multi-leg lifting straps
with suspension links must not be used in acidic
conditions. Contact of metal materials with acids or
their vapours can lead to hydrogen embrittlement.
• Avoid frost formation on lifting straps. In frosty
conditions, ice crystals form in damp lifting straps
and damage the load-bearing fabric. This results in
a reduction in the working load limit and loss of
strength. Ice also reduces the flexibility of the lifting
strap and, in extreme cases, makes the lifting strap
unusable, which is why wet lifting straps must be
dried in ventilated rooms before reusing them.

• Avoid strong ultraviolet light or intense exposure to
sunlight.
• Keep lifting straps away from direct heat sources
such as flying sparks or welding work.
• Never drag the load or other objects over the textile
attachment device.
• Never pull the lifting straps over the ground or rough
surfaces.

5. Description of operation

Serious accidents can occur resulting in
injuries or even death if the description
of operation is ignored!
• The EN 1492-1 standard and the general rules for the
lifting of loads applicable in the individual countries
(e. g. in Germany: DGUV rule 100-500, formerly
BGR 500) must be observed.
• The lifting strap is a universally usable attachment
device for the attachment and lifting of loads, which
can be used within the limits defined in these
operating instructions.
• Loads up to the specified working load limit can be
lifted.
• Load/attachment-specific reduction factors such as
the mode factors must be taken into account.

6. Description/Technical data

6.1 In general

• The flat-woven fabric of the lifting straps is made of
high-strength man-made fibres such as polyamide
(PA), polyester (PES) or polypropylene (PP) and has
a selective resistance to chemicals.
• Polyester (PES) is resistant to most mineral acids, but
is attacked and destroyed by alkalis.
• Polyamides (PA) are practically resistant to the action
of alkalis, but are attacked by mineral acids.
• Polypropylene (PP) is hardly attacked by acids and
alkalis and is suitable for applications where maximum
resistance to chemicals other than solvents is required.
• Lifting straps include: single-ply, two-ply or four-ply
lifting straps with loops as well as flat-woven
single-ply, two-ply or four-ply endless lifting straps.
