The present invention relates to a mechanically advantaged system that is purposed to spread opposing surfaces with user input. This apparatus needs only one operator. This apparatus can be used to move or spread material or equipment over a long-range, by extending the base unit 2 inches at a time, or by adding multiple extension tubes of 1 foot, 2 foot, 4 foot, or custom length extensions.

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 lifting apparatus and lifting system for lifting a shipping container (14) are disclosed. The lifting system uses four lifting apparatus one in each corner of the container (14). Each apparatus has a hydraulic cylinder (16) which is attached to a frame (24). A locking member (40, 90) also attached to the frame (24) engages the base corner block (44) of the shipping container (14) and locks thereto. There is also a container frame engaging member (60) which presses into engagement with the frame of the container (14) above the base corner block (44) but below the upper corner block (44). When the hydraulic cylinder (16) extends the container (14) is lifted and the container frame engaging member (60) presses into engagement with the frame of the container (14) locking the lifting apparatus onto the container (14).
