A drive system (35) for a people conveyor (1) comprises a conveyance chain (15) including a plurality of chain links (36) connected to each other; a plurality of legs (38) configured for connecting the conveyance chain (15) with the conveyance elements (13); and a plurality of levers (40). Each leg (38) is connected to at least two different chain links (36) by at least two of the levers (40). Each of the levers (40) is pivotably connected to one of the chain links (36) and pivotably connected to one of the legs (38).

A passenger conveyor (10) comprises a plurality of treads (16) interconnected to form an endless tread band (17), the passenger conveyor (10) comprising a chain and sprocket drive system including at least two drive sprockets (24a, 24b), each drive sprocket (24a, 24b) drivingly coupled to a respective drive chain (20a, 20b), each drive sprocket (24a, 24b) having a predetermined number of drive sprocket teeth (38a, 38b) positioned at a predetermined drive sprocket teeth pitch (a, b) with respect to each other, wherein the drive sprockets (24a, 24b) are configured to rotate with the same angular velocity, but at a predetermined phase difference () with respect to each other.

A fixing module (2) for fixing a pallet (8) of a pallet conveyor, in particular a people conveyor, to a pallet chain (40; 50; 90) comprises a pallet side (4) comprising a connection portion (6), which is configured to be fixed in a non-rotatable manner to a pallet (8) of a pallet conveyor; a pallet chain side (10), which is configured for facing the pallet chain (40; 50; 90) and for receiving at least one fixing element (47) protruding from the pallet chain (40; 50; 90); and a securing mechanism (12, 14, 16), comprising at least one moveable securing element (12) which is configured for securing the at least one fixing element (47) within the fixing module (2) so that the fixing module (2) is non-rotatably fixed to the pallet chain (40; 50; 90).

A polygon compensation coupling system for reducing a polygon effect in a chain driven system is disclosed. The polygon compensation coupling system may include a chain sprocket and a main drive in engagement with the chain sprocket, such that the engagement defines a compensation curve to reduce the polygon effect.
