Water Testing for Heavy Equipment Cabs: Quality Built Into the Process

“We wanted to build something that we can use to certify that we’re giving OEMs a complete cab that can withstand the weather and other elements in it’s working environment.”

For heavy equipment OEMs, an operator cab is more than a structure surrounding a seat. It is an integrated workspace that brings together the controls, visibility, comfort, and application-specific features operators need to do their jobs. GS Global Resources designs custom cab systems around those requirements, from compact single-person cabs to complex, multi-person operator environments.

That same application-focused approach extends to testing.

When a customer needed water-leak testing for its cab system, GS Global Resources’ engineering and sales teams identified an opportunity to strengthen the quality process. Rather than adapt the requirement to an off-the-shelf solution that did not adequately fit the application, the team developed a purpose-built system to test the cabs GS Global Resources produces.

The result is a repeatable water-testing process designed to evaluate cab water intrusion before the product leaves the facility—and provide another layer of confidence in the finished operator environment.

Developing a Water Test Around the Cab’s Requirements

The project began with a specific customer need and a practical engineering challenge: finding equipment suited to leak testing GS Global Resources’ cab systems.

As the quality engineer explains in the interview, available equipment did not adequately address what the team needed for the cabs and applications involved. Engineering and sales approached the challenge as a continuous improvement project, with the goal of developing a robust testing solution for cabs used outdoors across different industries.

The team consulted companies experienced in building this type of equipment, compared existing approaches with GS Global Resources’ requirements, and developed a prototype. That process established a starting point for a system tailored to the company’s cab-testing needs.

The project reflects an important part of GS Global Resources’ approach to quality: when a requirement calls for a different solution, the team works to develop the capability needed to address it.

How GS Global Resources Tests Operator Cabs for Water Intrusion

The water-testing system described in the interview uses approximately 60 gallons per minute of water flow distributed across 12 nozzles positioned at 12 different angles. This arrangement directs water around the cab, with coverage from side to side and top to bottom as extensively as the setup allows.

These specifications describe the system at the time of the interview.

The nozzle arrangement and standardized cycle work together. The system does not simply apply water to one surface; it directs water toward the cab from multiple angles using a defined test sequence.

“We systemize the test at about five minutes, so each test is standardized,” the quality engineer explains. “Each test hits all the same exact spots.”

That repeatability is central to the process: the test provides a consistent way to evaluate the cab under the water-exposure conditions created by the system.

Connecting Cab Design, Manufacturing, and Quality

The water-testing project illustrates how customer requirements can influence more than the cab design itself. They can also shape the equipment and processes used to evaluate the finished product.

In the interview, the quality engineer connects the project directly to checking product quality before shipment and supporting customer satisfaction. Testing becomes part of delivering the cab—not simply a separate activity after design and assembly.

This fits within GS Global Resources’ broader approach to operator cab development. Together with ADC Equipment Innovations, GS Global Resources supports cab projects from initial concepts and prototypes through fully populated, tested, plug-and-play solutions tailored to the machine and application.

Those capabilities bring the structure and operator systems into the same development conversation. Depending on the application, a custom cab may incorporate:

• Application controls, displays, and joystick assemblies.

• Custom seating, armrests, and switch panels.

• HVAC and application-specific glass.

• Camera and safety systems.

• Layouts designed around space constraints, operator visibility, and ergonomics.

Water testing adds a focused quality check within that broader cab-development process. It addresses water intrusion under the defined test conditions while other design requirements and testing activities address their respective aspects of cab performance.

What This Means for Heavy Equipment OEMs

For an OEM selecting an operator cab partner, the value of this project extends beyond the test equipment itself.

Customer requirements inform the process

The system originated with a customer requirement. GS Global Resources used that requirement to guide the development of a testing capability suited to the application.

Test consistency is part of the quality approach

The approximately five-minute cycle and defined nozzle arrangement establish a repeatable process rather than relying on an inconsistent application of water.

Quality checks extend to the finished cab

The engineer describes the system as a way to evaluate product quality before the cab leaves the facility, supporting the connection between what GS Global Resources designs, what it builds, and what it delivers.

Cab development considers the complete operator environment

GS Global Resources’ capabilities extend beyond the cab structure to the controls, comfort features, and integrated systems inside it. That allows OEMs to discuss the operator environment as a complete system tailored to their machine.gsglobalresources+1

Start With Your Machine’s Cab Requirements

A successful cab project starts with a clear understanding of the machine, its operators, and its intended application.

GS Global Resources works with heavy equipment OEMs to develop custom operator cabs that combine application-specific structures, integrated controls, ergonomics, and testing requirements. From initial concepts to fully populated cab systems, the goal is to deliver an operator environment designed around the machine’s needs.
