Installing the 8-wheel crane

This installation procedure is similar to the installation procedure for a normal double girder travelling crane.

If the main girders are delivered with end carriages fitted: The end carriages are already tightened to the correct tightening torque.

For 8-wheel crane version N: The main girders are (as is the case for a normal double girder travelling crane) screwed to the end carriage using two mounting plates on each side.

For 8-wheel crane version H: The main girders are screwed to the end carriage using three mounting plates on each side.

Start by installing one coupling bar to an end carriage on one side. See the following section.

Then install the other coupling bar on the opposite side of the other end carriage. See the following section.

If it is not possible to fit the coupling bars this way on the ground, the coupling bars can also only be fitted when both main girders are on the crane track.

Only for end carriage of the sizes 200 to 420

This work step only applies if the crane is an 8-wheel crane (four individual end carriages joined with a coupling bar) and the end carriage size is 200 to 420.

Assigning the coupling bar

	Markings

Coupling bar	End carriage

Find the markings (for the installation direction) on the coupling bars and on the end carriages.

1, 2, 3 or 4 centre markings have been punched in. The number of centre markings must match.

Fitting the coupling bar

Coupling bar

Bore hole for flanged bolts

Individual end carriage

Place the coupling bars on the end carriage so the markings (for the installation direction) match.

Move the coupling bar so that the holes for the flanged bolt are on top of one another.

Tip:

Rib screw M12x50	Rib nut M12

To make positioning the coupling bar easier, insert a rib screw M12x50 with a rib nut M12 into the openings on the edge of the coupling bar and adjust the position of the coupling bar by turning the rib nut.


Flanged bolt	Screw or threaded rod

Screw a screw M10 or M12 or a threaded rod into the flanged bolt.

Push the flanged bolt from inside through the hole.

Guide the flanged bolt with the aid of the screw or threaded rod, and push it right through the coupling bar.


Cover	Rib screw

Put on the cover.

Screw the rib screws in.

End carriage size	Type, size and length	Number	Tightening torque
200	Rib screw M10x20	3x	85 Nm
280	Rib screw M12x25	3x	130 Nm
350	Rib screw M12x25	3x	130 Nm
420	Rib screw M12x25	4x	130 Nm

Only for size 500 end carriage

This work step only applies if the crane is an 8-wheel crane (four individual end carriages joined with a coupling bar) and the end carriage size is 500.
