A tool for replacing an escalator drive shaft comprises a first tool and a second tool. One side of the first tool is adapted to be assembled on an original shaft adapter, and the other side of the first tool is adapted to be assembled on a new shaft adapter. The second tool is adapted to be assembled on the first tool. A central axis of the first tool coincides with a central axis of the original shaft adapter, a central axis of the second tool coincides with the central axis of the first tool, and the central axis of the first tool coincides with a central axis of the new shaft adapter. A positioning reference of the original drive shaft is accurately transferred to the new drive shaft by the first and second tools, so that the new drive shaft may be accurately assembled to the position of the original drive shaft with respect to the truss after replacement.

A conveyor system for displacing passenger/goods formed by a moving endless belt comprising a plurality of pallet assemblies and drive means to transmit a drive movement to the pallet belt. The pallets have a functional surface opposite to the support surface and having first meshing means. The drive means comprise second meshing means designed to interact with the first meshing means, so that the drive pallets, are driven by the drive means by means of a meshing between the first meshing means and the second meshing means and to drive said pallet belt in the movement direction D. The drive means have a linear motor aligned with the movement direction D.
