Embodiment Construction

[0024] figure 2 is a perspective view of a pipe laying machine 100 according to one embodiment of the present invention. The pipelayer 100 includes a main assembly 150a mounted on an underframe 150b such that the main assembly 150a is rotatable relative to the underframe 150b. In the position shown, the longitudinal axis L of the main assembly 150a mf with the longitudinal axis L of the chassis 150b uc vertical.

[0025] Main assembly 150a may include mainframe 105, adapter 110, cab 115, boom 120, piston and cylinder assembly 125, winch 130, pulley block 135, load block 140, counterweights 145 and engine 147. The main chassis 105 has a first side 105a and a second side 105b distal to the first side 105a. The adapter 110 and the driver's cab 115 are attached to the first side 105a. The first longitudinal end of the boom 120 is pivotally connected to the adapter 110 at 120p. As used herein, the terms "articulated" or "pivot" include single-axis pivots, such as hinges, an...

Abstract

A pipelayer having an undercarriage with at least two tracks and a main assembly. Each track has a track frame coupled to the undercarriage and a track shoe supported by and movable around the track frame. The main assembly is supported by and rotatable relative to the undercarriage, and has a main frame, a boom pivotally mounted to the main frame, an operator cab, and a cab riser connecting the operator cab to the main frame. The cab riser is operable to selectively raise and lower the operator cab relative to the main frame. Also provided is a movable cab assembly having an operator cab, an adjustment mechanism to connect the cab to a vehicle frame and move to change the operator's view, and a guide to align the cab. A method for laying pipe using a pipelayer having a movable cab is also provided.

[0003] US Patent Application Serial No. 11 / 746,464, filed May 9, 2007, is hereby incorporated by reference in its entirety. technical field [0004] Embodiments of the present invention generally relate to a pipelayer equipped with a lift cab. Background technique [0005] figure 1 It is a front view of a prior art pipe laying machine 10 . The pipelaying machine 10 is typically used for the laying of underground pipelines for transporting hydrocarbons, such as natural gas or gasoline. Typical operations of the pipelayer are raising, carrying and lowering heavy pipes 12 . Pipelayer 10 may be a tracked or traction locomotive having a steerable boom 42 on one side thereof. For the above reasons, the pipelayer 10 is also referred to as a sideboom. [0006] ...
