Abstract: The present invention relates to a wheel rim extender device (1) removably mountable on a wheel (3) having a tire retaining rim (27) for engaging an outer surface of a tire (5). The device (1) has an annular member (11) for location adjacent a sidewall (7) of a tire (5) mounted on the wheel (3). The annular member (11) comprises an edge portion (33a, 33b) which defines an outer circumference of the annular member (11) and a support portion (35a, 35b), disposed radially inward of the edge portion (33a, 33b), for mounting on the wheel (3), wherein the edge portion (33a, 33b) has a greater flexibility than the support portion (35a, 35b). The invention also relates to the combination of a wheel rim extender device (1) and a wheel (3).

Abstract: A retrofit handrail extension system or kit enables a large mining truck to be retrofitted in the field. The handrail extension system includes a first handrail extension member for connecting a first upper portion of a first ladder to a railing mounted to a catwalk around the cabin of the truck and a second handrail extension member for connecting a second upper portion of the first ladder to a forward-facing handrail mounted to an outer surface of the cabin of the truck. The system may include a third handrail extension member for connecting a first upper portion of a second ladder to a first platform railing mounted to a platform beside the cabin of the truck and a fourth handrail extension member for connecting a second upper portion of the second ladder to a second platform railing mounted to the platform beside the cabin of the truck.
