 |
4-Sided Pit
|
| Individual Slide Rail components offer the option of using lighter equipment when installing the system. The cost of rental and installation of the system is approximately 50% of steel sheeting. |
Benefits
- Installation and required excavation are completed together, saving time and reducing cost.
- Wall to wall working space is greater.
- Minimal vibration to adjacent buildings and surrounding structures.
|
Features
- Reinforced top rails.
- Strongest post & panel connection in the industry.
- Bolt-on collars for using SRS panels as standard trench shields (optional).
- Thru wall lifting lugs.
- 4 point lifting system.
- Strongest knife edge in the industry.
- Plug welding.
- High strength mill certified steel.
- P.E. depth certification chart.

ClearSpan System
|
| Efficiency Production's innovative ClearSpan System incorporates special walers for larger unobstructed 4-sided working pits for site specific jobs. Ideal for pump stations, and other large structures. |
Benefits
- Provides a large unobstructed working area.
- Cost effective compared to steel sheeting and other methods.
- Heavy duty panels provide minimal deflection.
- Minimal vibration to adjacent buildings and surrounding structures.
|
Features
- Reinforced top rails.
- Strongest post & panel connection in the industry.
- Bolt-on collars for using SRS panels as standard trench shields (optional).
- Thru wall lifting lugs.
- 4 point lifting system.
- Strongest knife edge in the industry.
- Plug welding.
- High strength mill certified steel.
- P.E. depth certification chart.

Linear Multiple Bay
|
| This configuration is an alternative to steel sheeting. It is used when installing next to existing utilities and structures, or when the trench is required to be left open. Longer pipe may be installed by raising or removing the parallel beam. |
Benefits
- Innovative Parallel Beam eliminates post deflection during installation and removal. The roller design facilitates the vertical movement of the integrated beam and spreader unit.
- The Parallel Beam can be used with spreaders or arches.
- Minimal vibration to adjacent buildings and surrounding structures.
|
Features
- Reinforced top rails.
- Strongest post & panel connection in the industry.
- Bolt-on collars for using SRS panels as standard trench shields (optional).
- Thru wall lifting lugs.
- 4 point lifting system.
- Strongest knife edge in the industry.
- Plug welding.
- High strength mill certified steel.
- P.E. depth certification chart.

Slide Rail / Shore-Trak Combo
|
| The industry's only pre-engineered Slide Rail & Shore-Trak cross trench utility shielding combination system. Efficiency's innovative system allows for shielding around existing utilities while providing excellent protection for pipe installation crews. |
Benefits
- Shore-Trak guide frames connect to Slide Rail posts where utilities are located.
- Shore-Trak panels measuring 22 1/2 inches in width and up to 24 ft. in length slide through the guide frame and are pinned-in-place before touching the existing utility.
- Provides shielding around existing utilities.
- Both systems can be used independently.
- Can be used in either pit or linear applications.
- Alternative to close sheeting.
- Minimal vibration to adjacent buildings and surrounding structures.

- Strongest post & panel connection in the industry.
- Bolt-on collars for using SRS panels as standard trench shields (optional).
- Thru wall lifting lugs.
- 4 point lifting system.
- Strongest knife edge in the industry.
- Plug welding.
- High strength mill certified steel.
- P.E. depth certification chart.

Following is a quick guideline for the installation and removal of a typical Linear Slide Rail with a Parallel Beam:
STANDARD LINEAR SLIDE RAIL WITH PARALLEL BEAM INSTALLATION
- Excavate a pilot cut two feet wider and two feet longer than the proposed bay size three to seven feet deep.
- Place the first post and parallel beam assembly in the pilot cut and lean it against the back bank furthest from excavator.
- Install one panel into both linear posts. Position the ends of the panels at the proper distance apart to receive the next post and spreader assembly.
- Install the next post and parallel beam assembly onto the ends of the panels in the pilot cut.
- Once the system is in its desired location and the posts are perpendicular, backfill outside of the panels to secure the system in this position.
- Excavate and push the panels and parallel beam posts down in 1-foot increments, alternating from one end to the other until they are to the bottom of the excavation, then push the parallel beam back to the bottom of the posts.
Note: Parallel beams should always stay at the bottom of the posts until the desired grade is accomplished. The parallel beam assembly may be raised and repined in desired locations for pipe clearance by placing twist lock pins below the beam assembly as prescribed in the tabulated data.
- When excavation reaches 8’ in depth, install 4’ or 8’ stacking panels onto the existing 8’ panels and pin them together.
- Continue to excavate and push the system until a depth of 12’ is accomplished.
- Repeat this process until the desired depth is reached and the necessary number of bays are installed.
STANDARD LINEAR SLIDE RAIL WITH PARALLEL BEAM REMOVAL
- Backfill and compact 2 to 4 feet and pull inside panels up to the level of the backfill.
- Repeat backfill compaction process. Pull first set of posts and spreaders to the bottom of the panels.
Note: Do not pull second set of posts and spreaders; these must remain in place to support the next bay. If the second set of posts and spreaders begin to rise with the panels of the first bay, it is necessary to push them down, to continue supporting the next bay.
- Continue backfill, compaction, and pulling process until the bottom of the inside panels are above the outside panels. At this time, the inside panels may be completely removed from the excavation.
- Resume the backfill and pulling process on the outside panels and posts until the entire bay is backfilled and removed.
- Pull the first set of posts and spreaders the rest of the way out and lay them aside.
- Remove the next bay by repeating the same process used to pull the first bay, and continue the process until all of the bays are removed.
