A method and apparatus for transporting heavy machinery, equipment or other heavy loads from one location to another, whereby the apparatus may be constructed as a walking machine including a plurality of lifting assemblies operative to lift the load above the supporting surface and then move the load relative to the supporting surface by transporting the load via rollers or tracks in the walking machines. In one example, the lifting assemblies are provided with separate longitudinal and lateral drive mechanisms independently operative for translating the load in either or both longitudinal and lateral directions.

A trailer tipper features multi-use tilt sensors for automating leveling and tipping operations. In an example, a computerized method for controlling operation of a trailer tipper is disclosed. The trailer tipper includes a frame at least partially supported relative to a ground surface by a set of outriggers. The trailer tipper further includes a tipping platform that is rotatable relative to the frame about a hinge axis. The computerized method includes a plurality of operations that may be used to at least partially automate leveling and tipping operations.

Test flange assemblies comprise a flange body and a piston. The piston is configured to translate relative to the flange body and has an outer surface facing away from the flange body and an inner surface facing toward the flange body. The outer surface defines a circular seal channel for receiving a seal structure between the piston and a flange surface of a flanged component. The outer surface radially inward from the circular seal channel has a surface area that is less than a surface area of the inner surface. Methods of testing pressure containing structures comprise operatively positioning the test flange assembly, positioning a seal structure within the circular seal channel of the piston, coupling the flange body to a flanged component, and pressurizing a volume between the piston and the flange body so that the piston compresses the seal structure between the piston and the flanged component.
