It will be noticeable that there has been provided a selfcontained compact machine having sufiicient tractive capacity to satisfactorily meet all running problems and tailored to provide the required covering and wrapping in a neat, wholly and efiicient adequate manner. Moreover, the detailed agreement of components generates a large reduction in the volume of parts and total body weight. It will likewise be obvious that the machine, having a reduced middle of gravitational pressure, possesses totally personal-comprised steadiness. Since the crawler carriage is: roller attached, it can be out of the question for the machine to upset during the pipeline.
1. Inside a pipeline layer and wrapping machine, a frame, plus a crawler carriage comprising a couple of axially aligned finish bands, another engagement ring in spaced axial alignment among explained end rings and significantly equidistantly spaced therefrom, helping plates attaching said rings, mentioned bands offering a passing with the carriage for wedding reception of any pipeline, explained framework possessing a plurality of number of rollers each fascinating the periphery of your individual certainly one of said finish rings to revolvably secure the carriage from the framework, and several traction rims attached to said dishes between each explained stop ring and 3rd engagement ring, each explained tire using a tractive periphery stretching into explained passing for proposal with explained pipeline, and being angnlarly disposed with respect to the lateral faces of mentioned jewelry to make it possible for circumferential traversal of explained pipeline, explained 3rd diamond ring possessing a driving sprocket around the periphery thereof.
2. Inside a pipeline layer and wrapping machine, a structure, and wrapping device revolvably taken by said framework and comprising a revolvable diamond ring, at least one wrapper roll left arm taken by said engagement ring in angular connection thereto, a spool rotatably carried by explained left arm, and braking implies maintained from the left arm and engaging stated spool, explained braking means comprising a braking system drum along with a braking system cover journalled on mentioned left arm, a sneaker pivotally carried through the drum, a lever for actuating the shoes pivoted to said cover and having a flexible, tough exposure to explained shoe, and a rod repaired on the handle for operating stated handle, said rod getting an angular segment organized to drive with a roll transported by explained spool.
