Porticos Designs High-Impact Shield Mount for Construction Equipment

Porticos, a product design and product development engineering consulting firm in Morrisville, NC. This project is an example of Porticos’ design and engineering expertise, crafting solutions for heavy industrial machinery and other heavy equipment.

For the operation of large construction equipment, such as an excavator or backhoe operator, shields are undeniably crucial and necessary to execute the operation of said machinery effectively. During the hammering operation at quarries and in mining sites, shields protect operators from debris, and keep them moving forward steadily on difficult terrain.

With so many different cab models, it can be extremely difficult to focus on suggesting a certain type of shield while respecting industry specifications. This is due to the variety in cab frames, the sizes of the cabs, and what those who are handling the machinery hope to gain from a shield. The geometry and curvature of the cab’s glass also has to be considered, along with the location and availability of bosses.

Many frame designs require a unique attachment strategy for each cab style—because of the variety in location, depth and the number of bosses welded onto a cab’s frame. This leads to distinct and obvious issues with parts, training, installation, cost, and more.

Porticos’ hardware engineering team sought to create shield mounts that could both be strong enough to protect operators, and flexible enough to accommodate multiple cab models. This innovative concept design required attention to the industrial standard, and an awareness of the mechanisms used to make the cabs themselves function above all else.

To solve this unique product design challenge for this particular heavy industrial machinery, Porticos worked with many industry partners. From there, Porticos’ hardware engineering team developed a distinctive mount—a combination of brackets with slotted holes, universal ball joints and threaded rods that enabled the shield to mount to the frame of any cab without any issues.

Through this process, Porticos was able to find the perfect solution to reduce the number of unique parts needed for the installation of a sheila, and make a modular kit that is flexible enough to accommodate the majority of the varied cab model styles.
