An end frame includes a guide having a channel therethrough for receiving a sheet piling and a pair of hangers for hanging the end frame from a spreader of a trench shield. The end frame hangs from the spreader and bears against the adjacent ends of the sidewalls of the trench shield to provide a channel through which sheet piling can be inserted and stabilized as the sheet piling is driven into the soil adjacent to the end of the trench shield. The sheet piling and the end frame prevent unwanted cave-ins of soil into the workspace between the sidewalls of the trench shield without imparting unwanted buckling forces to the midsection of the spreader from which the end frame hangs. The hangers may be rigidly coupled to the guide or they may be coupled to the guide through chains, cables, straps or through pivoting linkages.

A trench box which has first and second side panels connected in parallel spaced relation by first and second lateral supports. Each lateral support comprises connection points at each end of each lateral support that connect the side panels to the lateral supports. The connection points maintain the side panels in parallel spaced relation and the lateral supports in parallel spaced relation between the side panels. Each connection point comprises a pivot connection that permits pivotal movement of the side panels relative to the lateral supports about a pivot axis, and a releasable connection spaced from the pivot connection in a direction perpendicular to the pivot axis. The releasable connection is selectively releasable to permit the respective first or second side panel to pivot about the pivot axis such that the panels are not parallel.

The present disclosure relates to a prop (10) comprising a first tube (14) and a second tube (16). The first tube (14) is telescopically connected to the second tube (16) for axially displacing the second tube (16) between a retracted position and an extended position. The first and second tubes (14, 16) each comprise a loading end for receiving an axial load from opposing load surfaces (62, 64) in the extended position. The first tube (14) and the second tube (16) are made from a plastics material.

System and methods for supporting and/or straightening a building wall are provided. The systems and methods utilize a pivot bracket.

An excavation support system and methods for installing and using same. The system includes a corner cart having a generally vertical back plate having a front surface, a back surface, a top end, and a bottom end; a generally horizontal base plate having a top side and a bottom side, the base plate attached to the back plate at about a 90-degree angle, proximate the bottom end of the back plate; at least one roller, connected to the back plate, extending from the back surface thereof, and a corner swivel brace disposed on the top side of the base plate and connected to the front surface of the back plate.
