Abstract
A pallet body (1) consists of a stepboard (2) with toothed front and rear edges, linking eyes (7, 8) that receive and guide linking and/or driving elements (21) and stepboard supporting elements (9, 10) that receive and guide preceding and following pallet bodies equipped with corresponding linking elements. The linking eyes and stepboard supporting elements are mounted on the one hand under the stepboard, within its lateral edges, and project on the other hand over a predetermined distance beyond the front and rear edges.
Claims7
A unitary, one-piece pallet body for travelators comprising:
- a treadplate having front and rear edges, said front and rear edges having teeth;
- connecting elements for receiving and guiding connecting components, said connecting elements having a horizontal axis, said connecting elements extending from and being unitary with said treadplate;
- and
- treadplate supporting elements for receiving and guiding leading and trailing pallet bodies in connection with corresponding connecting components, said treadplate supporting elements being arranged underneath, being unitary with, and protruding beyond the rear edge of said treadplate by a specified distance,
- wherein said connecting elements are configured as hollow cylinders and a fulcrum is provided between adjacent unitary, one-piece pallet bodies roughly midway beneath the end portions of the meshing teeth of the individual treadplates.
A method for inspecting and/or repairing a travelator equipped with a plurality of pallet bodies , each pallet body including a treadplate having front and rear edges, said front and rear edges having teeth;
- connecting elements for receiving and guiding connecting components, said connecting elements extending from and being unitary with said treadplate, and having a horizontal axis;
- and treadplate supporting elements for receiving and guiding leading and trailing pallet bodies in connection with corresponding connecting components, said treadplate supporting elements being arranged underneath, being unitary with, and protruding beyond the rear edge of said treadplate by a specified distance, wherein said connecting elements are configured as hollow cylinders and a fulcrum is provided between adjacent unitary, one-piece pallet bodies roughly midway beneath the end portions of the meshing teeth of the individual treadplates, the method comprising the steps of:
- removing only a single pallet body from a track in one of a plurality of transition zones of said pallet bodies whereby the track can run without said removed pallet body to the inspection or repair point,
- removing further pallet bodies from the track in situ, where necessary, and
- implementing the above steps in reverse sequence on completion of inspection or repair.
A unitary, one-piece pallet body for travelators comprising:
- a treadplate having front and rear edges, said front and rear edges having teeth;
- connecting element means for receiving and guiding connecting components, said connecting element means extending from and being unitary with said treadplate and having a horizontal axis;
- and
- treadplate supporting element means for receiving and guiding leading and trailing pallet bodies in connection with corresponding connecting components, said treadplate supporting element means being arranged underneath, being unitary with, and protruding beyond the rear edge of said treadplate by a specified distance,
- wherein said connecting element means are configured as hollow cylinders and a fulcrum is provided between adjacent unitary, one-piece pallet bodies roughly midway beneath the end portions of the meshing teeth of the individual treadplates.
