The conductor system VKL is installed on the profile head of the HB profile rail with brackets.

    Lay out the individual sections of the conductor system on the floor as they will later be installed on the HB profile rail.

For every section:

    Insert the section bottom in the bracket and latch it at the top.

    Install the feed unit at the location specified in the planning documents.

The feed unit is fixedly installed on a one-metre long section. This is installed as a regular section.

The sections are electrically connected with one another by means of connecting pins.

At every joint:

    Insert the connecting pins laterally in the rails of a section.

Insert the connecting pins in the rails preferably at varying depths. This will facilitate the positioning of the next section.

    Push the section up to the previous section.

    Insert the connecting pins of the previous section into the rails of the next section.

    Place a wood block at the end of a section and use hammer to strike the section against the previous one.

●   The connecting pins are inserted fully into the rail and are no longer visible.

Tip:

To prevent the conductor system slipping away during striking, fix the first section to the HB profile rail. To do this push a suitable piece of wood between the conductor system and the HB profile rail, place a second piece of wood on the conductor system and fix in place using a screw clamp.

A two-piece connector can also be used to connect the sections with each other mechanically.

At every joint:

    Push the halves of the connector onto the conductor system from above and below.

The two halves for top and bottom are identical.

    Align the connectors so that the plastic lugs slip precisely into the undercut on the conductor system.

    Insert the connectors into one another behind the conductor system.

One of the sections is now fixed to the bracket. The other sections remain loosely latched. This allows the entire conductor system to freely expand or contract when temperatures change. However, due to the one fixedly bolted section, the entire conductor system cannot slide into the brackets.

The section to be bolted should lie about in the middle (within the span of the conductor system).

Centred within the span of the conductor system:

    Screw the self-tapping screw from below into the bracket and section.

    Slide the current collector into the conductor system.

    Slide the current collector over the entire length of the conductor system to test it.

The current collector must move smoothly and not get caught, particularly at the joints.

On the trolley:

The carrier shaft can also be installed in drilled holes on which other add-on components (e.g. anti-collision device or HBF drive) have already been installed. In this case, remove the installed bolt and mount the add-on component with the carrier shaft.

    Turn the carrier shaft with the outer drilled hole toward the top or toward the bottom.

    Insert the SL safety clip.

    Rotate the towing mandrel as in the diagram.

    Insert the towing mandrel from below into the right eyelet on the current collector.

    Insert the towing mandrel from the left into the outer hole in the carrier shaft.

    Secure the towing mandrel with the SL safety clip.

Tip:

The assembly described above ensures that the current collector is positioned centred over the trolley. The current collector will therefore not bump against the end of the HB profile rail.

Summary:

─     Insert the carrier shaft into the right drilled hole on the trolley.

─     Insert the towing mandrel from the left into the carrier shaft.

─     Insert the towing mandrel into the right eyelet on the current collector.

Depending on the crane installation, the towing mandrel may protrude at the top over the conductor system VKL. If the towing mandrel causes problems (e.g. catches on things), it must be shortened.

If the towing mandrel protrudes at the top and is a problem:

    Saw or cut off the end of the towing mandrel.

On the towing mandrel is a notch to be used for shortening it.

On both ends of the conductor system:

    Place the retaining cap on the conductor system.

    Securely bolt the retaining cap from the back side with self-drilling screws (2x).

Every HB profile rail must be fitted with end caps on the profile ends. These prevent dirt from penetrating the HB profile rail and also serve as an end stopper to prevent the HB crane or trolley from falling out of the HB profile rail.

On the front and back of all HB profile rails:

    Push the spacer sleeve into the end cap.

Only with HB240: use the spacer sleeve with black coating. It is slightly longer than the spacer sleeve with silver or yellow coating.

    Put on the end cap.

If necessary, widen the HB profile rail slightly to enable insertion of the spacer sleeve.

    Insert a hexagon head screw through the HB profile rail and the spacer sleeve.

    Insert washer, screw on the self-locking M12 nut. 80 Nm.
