A shoring device for supporting trench side walls during construction. The shoring device has opposite shoring shields having conventionally located spreaders adjacent the upper edge of the shields and a second pair of spreaders disposed at an upper location. A pair of auxiliary spreaders are associated with the shield assembly. Each auxiliary spreader member consists of a structural member having connectors at opposite ends which are detachably securable to the interior walls of the shields at a location below the horizontal center line of the shields to substantially increase the shield capacity. The auxiliary spreaders would be used primarily when the maximum pipe clearance is not required to achieve a greater load factor.

Shoring device with load optional enhancing spreaders

A shoring device for supporting a trench. The device has opposite shields of non-conductive material such as fiberglass. Hydraulic actuators extend between the shields. A spring return assembly also extends between the shields and is enclosed in a tube. A positive locking device may be secured to either the actuator or spring return assembly. In an alternate embodiment, the shields may have removable sections to accommodate obstructions in the trench.

Shoring device

A finger guard for attachment to a shoring device made from a flexible material. The guard has a shield to protect the user's fingers and is held in place by a removable hinge pin which inserts into the shoring device.
