Installation of Massive Kits

What are Massive Kits? Please follow the link if you require general information. This page is about the installation of such kits and self-assembled trellis sets with 12 mm cross mounts and 4 mm cable. All the information on this page must be viewed in connection with the 10 to 25 installation diagrams of the respective cable system. Please use the link and navigate to the cable system you have purchased. The pictures shown here complement the flow charts (sequence diagrams) there, and also apply to the medium construction style (Medium Kits) when only cross mounts (and no eye screws) are included. Before ordering, please check to see if you need tools!

The symbols in the diagram represent the cross mounts. The red bars show the alignment of the grooves of the head. After drilling, all holes are cleaned with drill hole brushes and/or with a small air pump, and then the cross mounts are installed without the grub screws (photo); to do so, please refer to the product sheet of the cross mount WM 12153.

For some systems it is necessary to cut off one or more pieces of rope with approx. 30 cm overhang from the rope reel and loosely insert them into the grooves of the cable mounts (photo), without inserting or tightening the grub screws. On both sides, the wire ropes end at least 10 cm behind the mount. Further details can be found in the respective diagram. Slack/loose ropes are recognizable (in the diagram) as such due to the wavy shape.

The diagrams show an installation requiring as little cutting as possible and which does not need a turnbuckle (rope tensioner). For this purpose, the rope is initially laid slack in the first mount with about 10 cm overhang. The grub screw is inserted, moderately tightened, and in the second step again tightened whilst holding the mount with an open-end wrench (photo).

Then the wire rope is guided to the opposite mount and placed in the groove, gripped behind the mount with a mounting vice and pulled taut by hand (about 10 - 20 kg force). Often a second mounting vice for temporary fixing directly behind the holder (photo below) is helpful so that inserting and tightening the grub screw is easier. Then -- again with about 10 cm of overhang -- the rope is cut behind the holder with a rope/cable cutter.

In some cases, it is necessary to temporarily fix/fasten a tensioned wire rope without screwing the grub screw into the cross mount, because later another wire rope will be inserted there. This fixing of the pre-tensioned state is done with a second mounting vice directly behind the cable mount (photo), or with a clamping ring or a cross clamp, which is often included in the kit. After tightening the grub screw, the fix/fastener is removed.

If a rope runs through more than two mounts, it is initially fixed only to the outer mounts. In the middle mount, it is only inserted; the grub screws there are either not screwed in or are only screwed in for temporary fixation of the rope so it does not slip out. The final tightening of these grub screws is done at the end or if/when: in the respective mount, a second rope is inserted a little later, (photo) and the mount is marked bold red on the corresponding diagram.

In places where wire ropes intersect, free-floating cross clamps are placed when the diagrams show it. Finally, projecting rope ends behind the respective cable mount are bent so that they represent an extension of the cable axis. Thereafter, the rope ends still get pressed end sleeves (ferrules). If the ropes protrude about 10 cm each, as indicated, they can be easily grasped for re-tensioning there in later years, if necessary.
