Benefits of technology

The invention is a material transfer vehicle that has a stairway and a conveyor step for safely and easily accessing the operator's station. The stairway is located entirely within the vehicle and is easy to use. The use of the stairway and conveyor step makes the vehicle safer, more efficient, and easier to operate. The invention also includes an asphalt paving material, asphalt binder, asphalt paving machine, asphalt mat, and material transfer vehicle. The terms "actuator" and "linear actuator" are used to describe devices that generate force in a straight line. The invention provides a solution for safely and easily accessing the operator's station of a material transfer vehicle.

Problems solved by technology

A stairway is easier and safer to use than a vertical ladder; however, a conventional stairway would occupy too much space and / or would protrude outside the periphery of the material transfer vehicle, thereby creating its own safety hazard.

Embodiment Construction

[0030]This description of a preferred embodiment of the invention is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description of this invention. The drawing figures are not necessarily to scale, and certain features of the invention may be shown exaggerated in scale or in somewhat schematic form in the interest of clarity and conciseness.

[0031]As shown in FIG. 1, a conventional self-propelled material transfer vehicle 10 includes frame 12 that is supported on the roadway surface “S” by first wheel set 14 and second wheel set 16. Each of the wheel sets is driven by a hydraulic motor (not shown) that is supplied with fluid under pressure by one or more hydraulic pumps (also not shown). Vehicle 10 includes truck-receiving hopper 18 for receiving asphalt paving material from a supply truck (not shown). Truck-unloading conveyor 20 is operatively attached to the truck-receiving hopper and is adapted to convey aspha...

Abstract

A material transfer vehicle includes a frame and an operator's platform that is mounted on the frame. A conveyor is mounted on the frame, adjacent to and below the operator's platform. The conveyor is adapted to be moved between a working position and a travel position. An access stairway to the operator's station includes a side stair portion and a conveyor step that is mounted on the upper side of the conveyor.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application No. 62 / 407,689 which was filed on Oct. 13, 2016.FIELD OF THE INVENTION[0002]This invention relates generally to a material transfer vehicle that is adapted for transferring asphalt paving material from an asphalt supply truck to an asphalt paving machine. More particularly, the invention relates to a material transfer vehicle having an access stairway by which the operator may enter the operator's station.BACKGROUND OF THE INVENTION[0003]The traditional process for paving roadways with asphalt paving material is generally carried out by an asphalt paving machine and a number of supply trucks which transport the asphalt paving material from an asphalt production plant to the paving machine. The paving machine generally is self-propelled and driven by a wheeled or tracked drive system. A hopper is located at the front end of the machine to receive asphalt paving mater...
