The following requirements must be met in order for the trolley to be mounted.

─     The trolley can only be mounted on I-beams with a flange inclined up to 15° or a non-inclined flange.

─     The supporting structure on which the trolley is to be fastened (e.g. jib crane, supporting structure, hall ceiling, etc.) must have an adequate load capacity.

The load on the I-beam and the supporting structure is comprised of the weight of the trolley, the chain hoist, and the maximum load capacity of the chain hoist.

   Determine the weight of the trolley.

   Add the dead load of the chain hoist. If necessary, add the additional weight of the chain. See the product manual for the ABUS chain hoist.

   Add the maximum load capacity.

   Check the entire supporting structure as to whether it will support the expected load.

─     The flange width of the I-beam must match the flange width of the trolley.

   Measure the width of the I-beam.

   Check whether the flange width F of the I-beam is within the range specified on the travelling gear bolt.

If not, contact the ABUS service department. See ABUS Service.
