If the wire rope is damaged or has more broken wires than permitted (see Inspecting the wire rope), it must be replaced.
If the cable guide is damaged (see Inspecting the cable guide), it must be replaced.
The wire rope is a special lifting rope with a very high breaking strength. This ensures it has a longer service life than a normal wire rope. This is why only genuine wire ropes from ABUS may be used.
If the rope wedge or the rope socket are damaged (see Exchanging the fixed point crosshead with rope socket and rope wedge), they need to be replaced. They are usually replaced when the wire rope and cable guide are replaced.
These safety instructions apply specifically to changing the wire rope:
─ Cordon off a generous space for the work area under the wire rope hoist.
─ Ensure the floor is swept clean.
This reduces soiling of the new wire rope.
─ Scissors lift platform with adequate surface area for setting down the bottom block.
This is only possible with a reeving of 2/1 and 4/1.
Observe the load capacity of the lift platform!
─ If an unrolling device is available to unroll the wire rope, sufficient free space for this is required.
─ Position a scrap container or similar receptacle in the immediate vicinity of the lift platform and bottom block for the old wire rope.
─ For a wire rope diameter larger than 11 mm, the rope change should be performed with the aid of a second person.
Run the load hook to the highest
hook position.
Only with ABUS electrics 3 with ABULiner: move the load hook under the upper limit switch range.
Measure, and note, the position of the load
hook.
This makes adjusting the hoist limit switch after replacing the wire rope in many cases unnecessary.
If ABUControl is installed for the wire rope hoist, refer to the product manual “ABUControl”, section “Exchanging the wire rope” to prepare for the rope change.
Further steps for the wire rope change are then described in this product manual.

The rope guard in the bottom block will be damaged if the wire rope is pulled along the rope guard quickly to remove it from the bottom block. If the rope guard is to be used again, it should be disassembled beforehand.
ABUS recommends replacing the rope guard together with the wire rope.
|
Do not pull the rope guard apart forcefully! If the rope guard halves are pulled apart forcefully during disassembly, the catches will bend. This means the rope guard can no longer be fitted to be functional. Carefully open the rope guard with a screwdriver. |
On all openings on the bottom block:
Screwdriver |

Insert the screwdriver laterally
between the rope guard and bottom block cover as shown in the figure.
Use the screwdriver to unhook
the load hooks on the left and right of the rope guard at the same time.
Pull the rope guard (2x) apart
and remove it from the bottom block.

Roll out the wire rope without twisting it! The wire rope will bend and become damaged if it is unrolled incorrectly. Do not pull the wire rope upwards away from a horizontally-lying ring. Unroll the ring so it is vertically upright instead, and allow the wire rope to run onto the cable drum in the same direction as it was rolled onto the ring. |

Normally, the adjustment of the hoist limit switch after replacing the wire rope can in many cases be omitted, since the position of the load hook was previously measured and then travelled to again. In special cases (e.g. if the wire rope is severely damaged or has been incorrectly rolled onto the cable drum), the switching points may need to be readjusted.
Reset switching points for the
bottom hoist limiter, the top hoist limiter and the backup limiter.
