A system for transporting equipment and individuals within a conduit and/or a pipeline. The system includes a ground floor, a first floor, a connecting rod, an ovality compensation mechanism, a couple of holding arms at a top end of the system, and a winch. The ground floor and the first floor are configured to receive and keep an operator onto them. The ovality compensation mechanism is attached to a lower side of the first floor by utilizing a couple of connecting chains. The ovality compensation mechanism is configured to increase a diameter of a pipe segment of the pipeline.

A loading device for lifting an elongated object having an elongate axis includes a frame having a first fulcrum surface and a second fulcrum surface, a first effector arm that pivots about the first fulcrum surface, a second effector arm that pivots about the second fulcrum surface, and an actuator moving the first effector arm and the second effector arm between a retracted position and a deployed position.

A pipelayer machine may comprise a machine chassis; a towing winch assembly coupled to the machine chassis; an operator cabin supported by the machine chassis; an engine supported by the machine chassis; and a boom coupled to the machine chassis. The pipelayer machine may comprise a front portion and a rear portion. The towing winch assembly may be provided in the front portion of the pipelayer machine. The operator cabin may be provided between the towing winch assembly and the engine.

A programmable and remotely operated and controlled pipe laying apparatus and method of using it for transporting and laying pipe for a pipeline, that can receive, hold, transfer and/or transport and unload pipe in a ditch or other tight space otherwise requiring a side boom. The apparatus has a mobile platform with a longitudinal central axis. A support extends in an extensible manner from the mobile platform and aligns the weight of the pipe with that longitudinal central axis. A pipe holder is associated with the support to facilitate the receiving, holding, transferring and unloading of the pipe on the mobile platform. The apparatuses can cooperate and work in tandem to carry larger and heavier pipe than a single apparatus can handle.

The invention is embodied in a construction quality control tool that allows owners and contractors to meet design plans and specifications. It saves time and costs to both parties' budgets by easily measuring pipe grading while eliminating need for surveyors on site and quickly transmitting print data in real time for third-party inspectors to prepare as-built plans. Most importantly, it ensures pipes are installed safely and accurately to prevent construction issues in the future.

The preferred embodiment of the invention comprises two devices: (1) a pipe setter and (2) a remote processing and recording unit. The pipe setter is mounted inside the new pipe to be installed. The pipe setter helps the pipe installer reliably and accurately install pipe that matches the line and grade (fixed x, y z) per design plan. The remote processing and recording unit enables the construction superintendent and the third-party inspector monitoring the pipe installation in real time.

A pipe puller system and methods of pipe extraction are shown. In one example a pipe to be replaced is pulled by attaching a pulling force to multiple locations along a length of the pipe. In one example pulling forces can be varied between different attachment locations to better control or eliminate tearing of the pipe. In one example, a pipe loosening device may be used prior to pulling the pipe from the ground.
