Travelling cranes with end carriages which are a maximum of 2.5 m wide can, in the majority of cases, be transported fully assembled on the road. If the end carriages are installed, skip this section.

For travelling cranes with end carriages which are more than 2.5 m wide, the end carriages are dismantled for transportation. Continue reading.

   Look for the letter position markers A and B (for the installation sequence) on the main girders and end carriages.

   Lay both end carriages on the joint faces of the main girder in such a way that the letter position markers match.

   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 the connection surfaces. The hole patterns must lie exactly over one another.

   Check the high-tensile bolts. The high-tensile bolts must meet these requirements:

─     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.

   Only with end carriages of size 280, 350 and 420: Do not move, dismantle or damage the clamp brace in the end carriage.

   Place the mounting plate in the end carriage and hold it so the hole pattern properly overlaps.

   Place the washers on the high-tensile bolts with the bevel (chamfered edge) to the head of the screw.

   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 next end carriage following the same sequence of steps.

   Seal the access portal with a cap.
