Note:
If automatic intermediate brackets are used, ensure that the cable is pushed through all the intermediate
brackets before fixing the cable to the heavy-duty cable tensioner.
Tension the cable turning the turnbuckle until the tension indicator is between the "min" and "max"
markings on the mounting plate and secure it with the hex nut, as illustrated (Fig. 7d) . Once this gets
done, the cable is appropriately tensioned.
3. 3. 6 INSTALLING THE INTERMEDIATE BRACKETS
Important!
As you cannot do this later, ensure that the cable passes through intermediate brackets before the
cable ends' preparation and the cable tensioner installation.
3. 3. 6. 1 AUTOMATIC INTERMEDIATE BRACKET
Align the automatic intermediate bracket so that the cable guide is parallel to the cable and the arrow
on the support angle points upwards and install as illustrated (Fig. 8a, 8b, 8c) .
3. 3. 6. 2 MANUAL INTERMEDIATE BRACKET
Assemble the manual intermediate bracket to the system ensuring that the bracket is perpendicular to
the cable, as illustrated (Fig. 9a, 9b, 9c) .
3. 3. 7 INSTALLING THE STEEL CABLE
3. 3. 7. 1 PREPARING THE CABLE ENDS
If the universal cable tensioner is used, the cable must be prepared at one end only. Otherwise, both ends
need to be prepared. Use one of the following methods to prepare the cable ends for the connection to
the top bracket (or the top shock absorber, if used) and the cable tensioner.
3. 3. 7. 1. 1 FACTORY-FITTED CABLE CRIMPING
The factory-fitted cable end is crimped in the factory. The cable crimping is normally used only as the
upper cable end (Fig. 10a) .
3. 3. 7. 1. 2 CABLE END CRIMPING
Crimping the end piece of the cable is a critical process when installing the fall protection system.
The strength of the fall protection system largely depends on the crimping quality. Therefore, we
recommend adhering to the following guidelines:
• Crimping should preferably be done on the ground and, if possible, before transporting the cable
to the installation site.
• A hexagon head crimping tool is used for crimping.
• Distances between the crimpings must be maintained (Fig. 10b) .
• Insert the cable end in the cable end piece (Fig. 10c) to be crimped and mark the cable at the
beginning of the cable end piece using an adhesive tape.
• Then check the length of the cable to be crimped. It must be a minimum of 75 mm (2.9"). Then
reinsert the cable into the cable end piece to be crimped up to the marking (adhesive tape).
• Hold the cable end piece in the press and actuate the press. Repeat this process two more times
and ensure that the required distance of 10 mm (3/8") between the crimpings is maintained.
Important:
After every crimping, slip an indicator ring on the cable so that the loads can be checked later. Slide
the ring on the cable before crimping. If there is any doubt regarding the crimping quality, repeat the
process using a new cable and a new part to be crimped.
Note:
Never use an already crimped part again. The 10 mm (3/8") cable is not swaged with the electric
swaging machine.
3. 3. 7. 1. 3 SWAGELESS CABLE END
Assemble the swageless cable end as illustrated (Fig. 11) . Slide the jaw housing (Fig. 11, Pos. 1) over
the jaws (Fig. 11, Pos. 2) and screw the eye bolt (Fig. 11, Pos. 3) and the locknut (Fig. 11, Pos. 4) into the
jaw housing (Fig. 11, Pos. 1) . Then tighten the locknut (Fig. 11, Pos. 4) using a spanner.
3. 3. 7. 1. 4 CABLE END WITH CABLE GRIPS
Important:
The cable end with cable grips can be used only to fix the cable to the cable tensioner. Don't use this
cable end type to connect the cable to the top bracket.
4 cable grips and 1 thimble are required for making a cable loop. Prepare the cable end as illustrated
(Fig. 12a) . Always ensure the cable grip is mounted so that the block touches the operating length of
the cable and the U-bolt touches the free-end length of the cable.
The distance between the cable clamps should be 6 to 8 times the cable diameter - 50 to 80 mm (2"
to 3").
After preparing the cable loops, cover both cable ends with a shrink-fit hose (Fig. 12b) :
• for Ø8 mm (5/16") cable, use Ø9,5 mm (3/8")
• for Ø10 mm (3/8") cable, use Ø12,7 mm (1/2")
