overhaul required every 3 months per decree dated
June 9, 1993, article 23).
6.2. Regular maintenance
The following simple maintenance operations may
be carried out by unqualified personnel.
Refer to the fall arrest equipment operating and main-
tenance manuals for detailed control and maintenance
operations of:
– fall arrest device with winder, series BLOCFOR
– connectors, series M
6.2.1. Lubrication of wire ropes
The suspension and secondary wire ropes must be
regularly lubricated using an oiled cloth. Use semi-fluid
SAE 20/30.
Never use oil or grease containing
molybdenum disulphide or graphite
additives
6.2.2. Replacing the wire ropes
Only wire ropes approved by the TRACTEL Group
ensure the correct operation of the hoists in com-
plete safety.
SCAFOR TM wire rope is defined by:
itsTRACTEL •
®
S identification = a red strand with
the TRACTEL ® logo on the ferrule
its diameter = 6.5 mm •
its length •
its end fittings: •
- a hook with safety catch and
- a fused and tapered end (Fig. 4)
Danger
Examples of damaged wire rope to be replaced Fig. 13 -
its construction. •
If any of the faults below is detected the wire rope must
be replaced:
more than 12 broken wires over a 24 cm length •
damaged or deformed wire rope •
corrosion •
heat damage •
reduction of diameter of the suspension wire rope: •
minimum diameter = 5.9 mm.
Wire rope to be measured as shown in fig. 14.
6.2.3. Checking fall arrest device linked to the
seat support
Refer to the user manual for the
BLOCFOR™ fall arrest device.
a. Checking winder
Checking appearance:
Prohibit the use of all equipement showing signs of •
strain, oxidation, etc.
Do not put foreign products (oil, solvent, etc.) into •
the equipment.
Unwind the whole wire rope and check it for signs •
of damage (strain, broken wires, etc.), wind the
wire rope by guiding it.
Do not let go of the wire rope.
Clean and grease the wire rope with an oil-impre- •
gnated cloth.
Checking the grip:
Apply a sharp pull to the end of the wire rope by •
hand.
The winder must block the wire rope as soon as •
the release speed is reached.
Guide the wire rope to its starting position by let- •
ting it re-wind itself in the housing.
Do not let go of the wire rope.
Check that the winder anchor is positioned above •
the user and perpendicularly to the working posi-
tion.
b. Environment check
Check that the wire rope cannot touch a sharp •
edge.
Check that the fall arrest wire rope cannot touch •
and/or rub against an electrical cable or conductor
or any fluid-conveying equipment.
Check that the wire rope is not exposed to a tem- •
perature exceeding 100°C and to mechanical or
chemical strains.
