A towing vehicle includes a vehicle body, a coupling device, a floor board, and a step. The coupling device is disposed at a rear portion of the vehicle body to connect a towing object to the vehicle body. The floor board is disposed in the vehicle body. The step is disposed in the vehicle body at a position lower than the floor board to form a level difference between the step and the floor board. The step includes an upper surface and a plurality of sides that bounds the upper surface. The plurality of sides includes at a rear portion of the upper surface a rear side that extends rearward and outward from the floor board. The vehicle body includes a rear surface that extends upward from the rear side.

A handrail system for a work vehicle has a handrail including a first rail member configured to extend in first direction and a second rail member coupled to the first rail member and configured to extend in a second direction substantially perpendicular to the first direction. The handrail system also has a fold structure configured to couple the handrail to the work vehicle and move the handrail between an upright position and a folded position with respect to the work vehicle. When in the folded position, the handrail has a support surface that is elevated along a central area of the handrail higher than at least one side of the handrail.

A cargo box for a vehicle includes a base member having a first edge portion, a second edge portion, a first side edge portion and an opposing second side edge portion. A first cross sill extends across the base member. A second cross sill extends across the base member. A side panel member is coupled to the base member along one of the first and second side edge portions. The side panel member includes an opening. A step assembly includes a first step support coupled to the first cross sill, a second step support coupled to the second cross sill and at least one step member coupled to and extending between the first step support and second step support. The step member is arranged at the opening in the side panel member. The step member is decoupled from the side panel member.

A frozen accumulation detection assembly and method of operation for a motor vehicle is provided. The assembly includes a light source for emitting light on a surface of the motor vehicle, such as running board, and a sensor for measuring a reflectance level of the light off of the surface of the motor vehicle. The assembly further includes a heating element coupled to the surface of the motor vehicle. The reflectance level may be used as an indicator of frozen accumulation on the surface of the motor vehicle, and may help determine if the heating element should be energized.

Support devices and their components are disclosed, including an optional lighting element mountable on the support device for emitting light. The support device facilitates access to a vehicle and includes an elongate extruded support member, brackets for mounting the elongate extruded support member to a vehicle, and a step affixed to the elongate extruded support member. A mount can be provided and coupled to the lighting element and to the step to secure the lighting element to the step when the lighting element is incorporated.

Illustratively, an embodiment of the present disclosure provides a vehicle that includes an entrance to an interior compartment. A step assembly is located adjacent the entrance of the vehicle and includes at least one step and at least one riser. The at least one riser is attached to and substantially perpendicular to the at least one step. The step assembly also includes an opening that allows access behind the step assembly. A lid is provided that includes a hinge to allow selective movement of the lid between open and closed positions with respect to the opening in the step assembly. A securement is attached to the underside surface of the lid to hold the lid to the step assembly. This securement, however, does not extend upward from the top surface of the lid.

A combination tie down lug and step riser includes a foot support portion, a hold down loop and a mounting portion. The combination tie down lug and step riser is preferably fabricated from a single piece of material. The foot support portion includes a plurality of projections extending upward from a top edge thereof. The hold down loop extends from one end of the foot rest portion. The hold down loop includes a U-shaped opening with the U-shaped opening positioned along a horizontal axis. The mounting portion extends from an opposing end of the foot support portion. Opposing ends of the hold down loop and the mounting portion are attached to an excavator base with welding or any other suitable attachment method.
