The conveyor of a travelator comprises a number of shafts and a number of mutually parallel endless belts. The conveyor comprises a number of conveyor modules successively connected to each other with a connecting section between them. The belts in the connecting section are arranged to be loosenable so that at least one shaft over which the belts to be loosened are passed is detachable so as to allow the conveyor modules to be released from each other. To release a conveyor module, at least one shaft on which the belt loops in the connecting section turn over is moved in relation to another shaft to slacken the belt loops. The shaft over which the loosened belt loops are passed is detached and removed from the belt loops. The detached conveyor module is removed for maintenance and/or replaced. In the assembly, a number of conveyor modules are provided, the conveyor modules are placed one after the other and connected to each other in the connecting section by belt loops and at least one detachably mounted shaft, which is placed in the belt loops in the connecting section. At least one of the shafts over which the belt loops in the connecting section are passed is moved to tighten the belt loops and to form a substantially continuous conveyor surface across the connecting section.

The travelator conveyor according to claim 1, wherein the at least one connecting shaft in the connecting section includes two detachable shafts arranged to be movable towards and away from one another to slacken/tighten each connecting belt turned over the two detachable shafts. 3. The travelator conveyor according to claim 2, wherein each connecting belt is turned over at least one of the two detachable shafts and at least one of the module shafts disposed at the ends of the adjacent conveyor modules. 4. The travelator conveyor according to claim 1, wherein each connecting belt is longer than each of the plurality of mutually parallel endless belts in the conveyor modules. 5. The travelator conveyor according to claim 1, wherein the at least one connecting shaft in the connecting section includes a detachable shaft and two tensioning shafts, the two tensioning shafts being disposed at a different level relative to a level defined by the plurality of module shafts of each adjacent conveyor module, wherein the two tensioning shafts are movable towards/away from the level of the module shafts to allow the connecting belts to be loosened/tightened, and wherein each connecting belt is turned over the detachable shaft, one of the tensioning shafts, and at least one of the module shafts disposed at the ends of the adjacent conveyor modules. 6. The travelator conveyor according to claim 1, wherein the module shafts of each conveyor module include a detachable shaft at one end thereof, the detachable shaft being arranged to be movable in a direction parallel to the transport direction of the conveyor module to slacken/tighten the plurality of mutually parallel endless belts turned over the detachable shaft to allow the detachable shaft to be detached, and wherein the at least one connecting shaft of the connecting section is a tensioning shaft disposed at a different level relative to a plane defined by the module shafts of each adjacent conveyor module, the tensioning shaft being movable towards/away from the plane of the module shafts to allow the connecting belts to be loosened/tightened. 7. The travelator conveyor according to claim 6, wherein each connecting belt is longer than each of the plurality of mutually parallel endless belts and each connecting belt is turned over the detachable shaft of one of the adjacent conveyor modules, the tensioning shaft, and the module shaft disposed at an end of the other adjacent conveyor module. 8. The travelator conveyor according to claim 1, wherein the travelator is a low-construction travelator designed to be mounted on a fixed base, such as a floor or other support. 9. The travelator conveyor according to claim 1, further comprising an acceleration section for accelerating a passenger transport speed from a substantially slow initial speed to a heightened transport speed, a constant-speed section for conveying people at a constant transport speed, and a deceleration section for decelerating the passenger transport speed from the constant transport speed to a decelerated final speed. 10. A method for releasing a pre-assembled conveyor module of a travelator conveyor wherein the conveyor is assembled from a plurality of successively connected pre-assembled conveyor modules, each conveyor module defining a removable and replaceable subassembly including a plurality of module shafts arranged parallel to one another and a plurality of mutually parallel endless belts turned over two different module shafts, each conveyor module further being connected to an adjacent conveyor module by a connecting section, the connecting section including at least one connecting shaft and a plurality of endless connecting belts, the method comprising: moving the at least one connecting shaft relative to the module shafts to loosen at least one of the connecting belts; detaching and removing a detachable shaft over which the at least one loosened connecting belt is turned; and removing the conveyor module from the conveyor to allow the conveyor module to be serviced and replaced with another corresponding conveyor module. 11. The method according to claim 10, wherein the at least one connecting shaft comprises the detachable shaft and another detachable shaft, and wherein each of the connecting belts are turned over one of the two detachable shafts and a module shaft disposed at an end of one of the adjacent conveyor modules, wherein the moving comprises moving the two detachable shafts towards each other to slacken each connecting belt. 12.
