1. Mount the preassembled tensioner underneath the
bottom platform floor.
2. Place the threaded shaft in the toppest position
(see Fig. 8b).
3. Feed the guiding wire rope by hand through the
threaded shaft.
4. Stretch the wire rope pulling downwards.
5. Install the wire rope grips.
6. While locking the threaded shaft with a spanner in
the shaft indentations, turn the tensioning nut until
dial indicates 2KN – 4KN (see Fig. 8c).
7. Fasten the locking nut.
8. Mount the second tensioner.
1.3.4 Tensioning the guide wire ropes Ø0.47 in (12 mm)
Tighten the wire ropes by hand and mark with a water-
resistant marker. Measure the distance to the floor.
• For 197 ft (60 m) long wire rope, stretch the wire rope
2.36 in (60 mm).
• For 262.46 ft (80 m) long wire rope, stretch the wire
rope 3.15 in (80 mm).
• For 328.08 ft (100 m) long wire rope, stretch the wire
rope 3.94 in (100 mm).
For each additional 32.8 ft (10 m), stretch the wire rope
by a further 0.39 in (10 mm).
After some time it may be necessary to stretch 196,85 ft
(60 m) wire rope by another 1.19 in (5 mm) and longer
wire rope by a further 0.27-0.39 in (7-10 mm) (all wire
!
ropes stretches after some time).
ATTENTION!
This will tighten the wires to approximately 2000-
4000 N.

1.4 Electrical connections

1.4.1 Power supply

DANGER!
The electrical connection of the traction hoist must
be made in accordance with EN 60204-1.
The power supply must be protected by a fuse
and an earth leak circuit breaker (30mA).
Disconnect the main power supply before handling
power units.
Verify that the rated grid and motor voltages are
identical. The three-phase motor is normally
supplied in a star connection configuration:
400V 3 phases+gnd. Y I = 4.9A 1.8 kW 66 ft/min 21m/min
480V 3 phases+gnd. Y I = 4.1A 1.8 kW 66 ft/min 21m/min
Control voltage: 230 V / 240 V
Necessary equipment to comply with EN60204-1
can be supplied by Avanti as an option.
