Checking the braking distance

 

Only for braking function or shut-down

The brake on the crane travel drives is worn during operation. This lengthens the braking distance of the crane. The crane may therefore strike the end stopper of the crane track too fast and put excess pressure on the supporting structure (e.g. the building).

 

*   Suspend a load on the load hook which corresponds to the maximum load capacity of the crane.

*   Move the crane into the limit switch range.

*   Check the braking distance:

For braking function: the crane must run only at low speed just in front of the end stopper.

For shut-down: the crane must come to a standstill just in front of the end stopper.

*   If the braking distance is too long: Adjust the brake on the crane travel drive. See the product manual for the crane travel drive.
