How to choose the right trench shield supplier

choosing the right trench shield, supplier

When choosing a shield, you absolutely want something that is in good condition and can hold up well to prevent accidents or injuries. Buying or renting the right trench box can be a difficult task, as there are many different types and sizes of equipment available. Here are four questions to help your decision process:

  • Are there adjacent structures, surface obstructions, groundwater problems, or overhead obstructions? Some trench systems are installed using a crane or excavator, so if there is an overhead obstruction, a company may not be able to install this type of system.


  • What types of soils do you work in? Soils are classified (OSHA) as either stable rock or as Type A, Type B, or Type C soil, depending on their strength and stability.

  • Why or what are you excavating? The answer to this question will help determine the size of the shielding system your company may want to use. When a company installs a large manhole or similar, it will probably choose a different system than a crew installing a long gas line or a linear water line.


  • How big is the excavation? The width, depth, and length of the excavation will affect the size of the protection system required.

Trench Shield FAQ

Trench Shield: Frequently Asked Questions

What is trenching/excavation?

An excavation is any hole dug in the ground by removing material (such as soil). The trench is an excavation where the depth exceeds the width. There are many different types of construction sites that use trenching/excavation equipment. It is generally considered to be important and dangerous work because tons of soil or other materials are literally moved.


What are the dangers of trenching?

Trench boxes (shield) are designed to minimize the potential hazards of trenching and excavation, which are numerous. The most common hazard, or the one that results in the greatest number of deaths, is trench collapse.

How do I match a shoring box to my machine?

A shoring system should be well matched to the lifting capacity of your machine. If it's too light, it can be damaged, too heavy, and your machine will not be able to handle it. Simply check the lifting capacity of your machine or provide the information about your model, and ESC will make sure you have the right fit.


What does A/B/C flooring mean?

These are the OSHA soil classifications. Simply put,

  • Soil A is the best soil, such as rock or very cohesive material.

  • Soil C, on the other hand, is a material that you are very mobile with and is not cohesive.

  • Soil B would be in the middle.


It is very important that a competent and knowledgeable professional designate the soil type before selecting trenching equipment. You can get detailed information at


What are the advantages of modular shoring, i.e., modular trench boxes?

The advantages of modular trench boxes are numerous:

  • They allow you to transport them in smaller vehicles,

  • Move equipment in confined areas,

  • And build your system in a variety of heights and widths depending on job requirements.


What are the risks associated with excavation and trenching?

The trenches have what is known as downtime. This is the time between when the trench is dug and when the walls collapse. The resting time can range from a few seconds to several months, depending on factors such as depth, soil type, soil moisture content, weather conditions, and activity around the trench. Risks include, but are not limited to:

  • Collapses and collapses that can trap workers;

  • Excavated equipment or soil falling on workers (e.g., equipment in use or soil/debris stored too close to excavation)

  • Falling in the trench or excavation

  • Flooding or water accumulation

  • Exposure to a hazardous atmosphere (e.g., gas, vapors, dust, or lack of oxygen)

  • Contact with buried services such as electricity, natural gas, water, sewage, telecommunications, etc.

  • Contact with overhead power lines

  • Overturning by moving machines or by falling volatile objects

  • Risks associated with handling materials (e.g., lifting, tipping, crushing, etc.).
