Abstract

A pipeline padding machine includes two control station locations. One location is for controlling operation of the machine while the machine is operated on one side of a ditch, and the other location is for controlling operation of the machine while the machine is operated on an opposite side of the ditch. Another pipeline padding machine includes a material escalator assembly for elevating material, and a material conditioning assembly for conditioning the material. Another pipeline padding machine includes a main frame attached to a transport assembly for transporting the machine, a material escalator assembly for elevating material, and a cutting edge for cutting through the material prior to the material being elevated by the escalator assembly. The escalator assembly is pivotable relative to the main frame, and the cutting edge is pivotable relative to the escalator assembly.

Claims

1. A pipeline padding machine, comprising:

a first control station location for controlling operation of the machine while the machine is operated on a first lateral side of a ditch; and

a second control station location for controlling operation of the machine while the machine is operated on a second lateral side of the ditch,

wherein a first control station and a second control station concurrently exist at the respective first and second control station locations, and wherein the first and second control station locations are pivotable with a material escalator assembly relative to a main frame of the pipeline padding machine.
