Transportation safety device |
Unscrew the transportation
safety device.

|
Letter position markers |
|
| |
Look for the letter position
markers A and B (for the installation sequence) on the main girders and end
carriages.
Lay the end carriages in such a
way on the joint faces of the two main girders so that the letter position
markers are in agreement.
|
|
Danger of fatal injury! The crane and the load can fall if the end carriages are not correctly screwed onto the main girders. Prepare and screw in the screws carefully! |
|
Residual paint |
|
|
| |
|
|
Joint face |
Thoroughly clean the joint faces
on the entire surface.
There should not be any rust, dirt, paint or similar impurities on them.
|
|
Lift the end carriages in front of one of the two main girders. The
screw holes must lie exactly over one another.
Check the high-tensile bolts. The high-tensile bolts must
meet these requirements:
|
|
Material |
Size |
Lubrication |
|
High-tensile bolt (hexagonal) |
10.9 |
M20 |
|
|
Washer |
C 45 |
HV 21 |
MoS2 |
|
High-tensile nut (hexagonal) |
10 |
M20 |
MoS2 |
─ The high-tensile bolts and mounting plate with high-tensile nuts may only be installed with tightening torque a maximum of two times. If they are installed more than twice with tightening torque, the high-tensile bolts as well as the mounting plates with the high-tensile nuts must be scrapped.
Should it be necessary to loosen the high-tensile bolts during installation, the same high-tensile bolts can be reused a maximum of one more time, otherwise the lubrication will no longer be sufficient!
─ The high-tensile nuts and washers must be galvanised and lubricated with MoS2.
─ High-tensile bolts which have been installed on a crane for a lengthier period may not be used again.
The end carriages are initially only installed by manually screwing until hand-tight. They are finally firmly screwed (with a tightening torque) only after the crane is on the crane track and the trolley and all other components are installed. By doing so, the main girders can settle and the crane is not warped on the crane track. See Fastening the end carriages tightly.

Clamp brace |
|
| |
|
Mounting plate | |
Place the mounting plate in the
end carriage and hold it so the hole pattern properly overlaps.
|
High-tensile bolt with washer |
|
|
| |
Insert the high-tensile bolts
and washers from the outside into the screw holes and screw on so they are
somewhat loose.
|
|
Screw on the second main girder
appropriately between the two end carriages and according to the same process.
|
Access portal |
|
|
| |
|
|
Cap |
Seal the access portal with a
cap.
This work step only applies if the crane comes into contact with rainwater or condensation water (e.g. outdoor operation, semi-exposed building etc.)
The gap between the two joint faces must be sealed so that no water can penetrate and rust the metal parts.

|
Sealant |
| |
Squeeze sealant (supplied) with
a cartridge applicator gun into the joints between the main girders and the end
carriages. Only left, right and above.
The joints below remain free so that entrapped water can drain off.
Smooth the sealant in the
joint.
Clean away any smeared
sealant.
If necessary, reapply the
sealant. The sealant can be handled “wet on wet”, no drying time is
necessary.
