Each pallet comprises a pallet body, at least one surfacing element attached to the pallet body and a fastening mechanism to attach the at least one surfacing element to the pallet body. The fastening mechanism comprises at least one coupling element included in each surfacing element of the pallet, a form-locking groove included in the pallet body of the pallet and a locking element performing a locking operation with a locking movement and a releasing operation with a releasing movement. The locking element acts on all the coupling elements in the form-locking groove of the pallet body substantially simultaneously during the locking movement and the releasing movement. ## Claims ### Claim 1 A pallet arrangement for a people mover, comprising: a plurality of pallets arranged one after the other to form a track, each pallet comprising a pallet body, at least one surfacing element attached to the pallet body and a fastening mechanism to attach the at least one surfacing element to the pallet body, the fastening mechanism comprising at least one coupling element included in each surfacing element of the pallet, a form-locking groove included in the pallet body of the pallet and a locking element performing a locking operation with a locking movement and a releasing operation with a releasing movement, the locking element acting on the at least one coupling element in the form-locking groove of the pallet body during the locking movement and the releasing movement, the locking element comprising an elongated piece extending substantially in a longitudinal direction of the pallet body and having a length substantially equal to a length of the body. ### Claim 2 (depends on 1) The pallet arrangement according to claim 1, wherein the at least one coupling element comprises a first and a second coupling elements, wherein the locking element acts on the first and the second coupling elements in the form-locking groove of the pallet body substantially simultaneously during the locking movement and the releasing movement. ### Claim 3 (depends on 1) The pallet arrangement according to claim 1, wherein the locking element is located substantially inside the pallet body with one end of the locking element extends outside the end of the pallet body. ### Claim 4 (depends on 3) The pallet arrangement according to claim 3, wherein the end of the locking element extending outside the pallet body has a form that allows the locking element to be easily moved to implement the locking and releasing movements. ### Claim 5 (depends on 1) The pallet arrangement according to claim 1, wherein the locking element comprise an eccentric bar having a longitudinal axis about which the eccentric bar is turnable, the eccentric bar having eccentric cams fitted to press the locking element in the form-locking groove into a locked position. ### Claim 6 (depends on 1) The pallet arrangement according to claim 1, wherein the locking element comprises a flat bar linearly movable in a longitudinal direction of the pallet body and including cutouts, the flat bar including an inner edge adapted to press the coupling element into a locked position in the form-locking groove. ### Claim 7 (depends on 1) The pallet arrangement according to claim 1, wherein the pallet body includes a first edge having a locking groove with a substantially L-formed cross-section, the at least one coupling element includes a coupling element in a lower surface of the surfacing element having a corresponding L-formed cross-section that fits into the L-formed groove in the pallet body, and the pallet body has a second edge including the form-locking groove and the at least one coupling element includes a coupling element in the lower surface of the surfacing element that fits into the form-locking groove and is lockable by the locking element. ### Claim 8 (depends on 7) The pallet arrangement according to claim 7, wherein the locking groove at the first edge of the surfacing element and the form-locking groove at the second edge of the surfacing element have substantially equal lengths and are substantially unchanged in cross-section over their entire length.
