Reduce your diesel fuel costs. Safely and carefully installing and moving trench shields is paramount. Steel shields can be heavy, and that means there is a high potential for danger. Aluminum shields are considerably lighter, but can be easily damaged by excavation equipment.

Using a Steel Trench Shield

There are a several techniques for using steel trench shields.

In stable soil, there are two steps:

  • Excavate in front of the shield.
  • Place excavator bucket around front spreader or use a chain/sling with pulling lugs, being careful not to damage the spreader or the collar. Pull the shield forward. Then promptly back fill behind the shield.Moving_Steel_Shield_1

In unstable soil, there are a few more steps:

  • Excavate a pilot hole as deep as possible. Set the shield in position.
  • Excavate inside the shield.
  • Continue digging, allowing the shield to descend as soil is removed. Use the bucket to push down on the shield. But don’t beat on the shield!
  • To move forward, place excavator bucket around the front spreader, being careful not to damage the spreader or the collar. Pull upward and forward at a 45-degree angle.Moving_Steel_Shield_2
  • Excavate inside of the shield and repeat the previous steps.Moving_Steel_Shield_3

Using an Aluminum Trench Shield

Because of the typical applications for aluminum shields, and the fact that aluminum is a softer metal, use of an aluminum shield is different. Typically, the hole is dug and the aluminum shield is set in place. When the work is complete, and it’s time to move the shield, the shield is lifted out of the hole and set in its new position.

In our next installment — Part 5, coming in a couple of weeks — we’ll look at how to unload, assemble, disassemble, and reload trench shields.
