Hydraulic Vertical Shoring Systems

3 Inch Hydraulic Corner Strut

The Pacific Shoring Hydraulic Strut is a 3” aluminum hydraulic cylinder mounted on 18” to 24” long heavy-duty waler rails.  The assembly also has an optional angle bracket so that the strut can be set on a wale and position the cylinder at the wale web.  Lift brackets are attached to the assembly for the purpose of setting the strut and providing vertical safety support so that the strut cannot fall into the excavation. 

In all situations, a competent person should determine that the strut is properly set and fixed into position

3 Inch Hydraulic Strut

A Hydraulic Strut is a 3” aluminum hydraulic cylinder mounted on 18” to 24” long heavy-duty waler rails. These are used on waled excavation support systems. 

This hydraulic strut is generally used on waled excavation support systems and directly on piles in pile and plate shoring systems. The Pacific Shoring Hydraulic Strut can be used in any situation where hydraulic force is needed.

6-Inch Hydraulic Strut

The Pacific Shoring Products 6-Inch Hydraulic Strut is designed to repurpose components used in the traditional 4-Way Hydraulic Brace System. This Single Ram application allows you to use a single 6-Inch Hydraulic Strut in conjunction with cylinder and socket side attachments. Together they can be used in waled excavation support systems as well as pile and plate shoring applications. The Pacific Shoring Products 6-Inch Hydraulic Strut is generally used in situations where hydraulic force is required. The system uses an auto-retractable 3-inch hydraulic cylinder with 36 inches of stroke that provides a 40,000 lb. safe working load. The cylinder is encapsulated in a 6-inch corner bracket and high-strength steel over sleeve extension assembly. 6-Inch Hydraulic Struts are designed to work in trenches up to 25 ft. in width and depth. In all situations, a competent person should determine that the strut is properly set and fixed into position.

End Shores

The Pacific Shoring Products End Shores are all aluminum hydraulic shoring system designed specifically for protecting workers at the ends of trench and pit excavations. The End Shore is designed to work in trenches from 4 ft. to 20 ft. deep and 2 ft. to 12 ft. wide. Corrugated sheeting is set behind the shore against the trench wall to prevent trench wall collapse and raveling. The End Shore must be used in conjunction with independent linear shoring systems that protect the trench walls.

High Clearance Shore

High Clearance Shores are generally used on big pipe projects where the pipe being laid is greater than 36” in diameter. The Pacific Shoring High Clearance Shore provides clearance from the bottom of the trench.

These shores must be installed and removed from outside the trench. They are built from heavy-duty waler rails and double 2” or 3” cylinders. The horizontal spacing of these stores varies by the strength of the hydraulic cylinders. 

High Clearance Shores come in 8ft, 12ft, 16ft, and 20ft lengths. Allowable trench widths are 4ft to 12ft. Designs beyond these parameters are achievable when using a design by a registered engineer.

Aluminum Vertical Hydraulic Locking Shores

The Pacific Shoring Aluminum Hydraulic Locking Cylinder was developed to provide a mechanical mechanism that fully locks it in place so that it cannot collapse should the hydraulic pressure be reduced. A hand turn at the screw is all that is necessary. The end blocks are fully compatible with rails used on the PSH aluminum hydraulic shores.

Hydraulic Vertical Shoring Systems

 Hydraulic Vertical Aluminum Shores are used to support the sides of a trench and prevent a trench collapse. These lightweight shores can be transported, installed, and removed safely and easily. 

The shores are hinged so they can be folded when lowered into the trench and then opened. After, it is pressurized using a hydraulic hand pump which prevents cave-ins from happening.  The hydraulic fluid is water-soluble, environmentally safe, and biodegradable. 

These are typically used in linear trench applications and are installed outside the excavation. This tool is useful for repair and utility work such as sewer and water lines as well as any other projects that require effective spot bracing.

Horizontal Waler System – Cylinders

The Pacific Shoring Products Horizontal Waler System is generally used where it is not practical to use Hydraulic Vertical Shoring. The strength of the light-duty and heavy-duty waler rails allow for greater horizontal spacing of the hydraulic cylinders. The maximum vertical spacing of the wale and cylinders is 4 ft., the same as with Hydraulic Vertical Shoring; however, the horizontal spacing or clear span between cylinders can be as much as 10.5 ft. Horizontal Waler Systems are always used in conjunction with approved sheeting that can be driven behind the waler rails as the excavation proceeds to depth. This method is particularly useful in soft clays or running sand. Light-duty and heavy-duty waler rail lengths can vary from 4 ft. to 20 ft. in length. Horizontal Waler Systems have allowable trench widths of up to 15 ft. with maximum depths up to 20 ft.
