🎃 Happy Halloween from Team Klein! 👻

Things got a little spooky (and competitive!) at our Texas facility as our team brought their creativity, craftsmanship, and Halloween spirit to this year's scarecrow contest!

From clever designs to impressive attention to detail, our departments proved that their talents go well beyond building dependable equipment.

🏆 A big congratulations to our Paint Department for taking home 1st place! 🎨👏

And a special shoutout to everyone who participated and helped bring a little Halloween fun to the workplace.

At Klein, we take pride in what we build, but it's the people behind the work who make our team something special.

🦺 SAFETY BY DESIGN | PART 5

Some of the risks around a water truck happen when it isn’t moving at all.

Routine inspection and maintenance can require operators and technicians to access elevated areas of the tank. And one of the most critical moments can be the transition from the ladder to the top platform.

That’s why Klein offers the TRAM Fall Protection System for Klein tank systems.

TRAM is designed to help protect personnel while accessing and working in elevated areas of the tank, providing:

✔ Fall-restraint or fall-arrest protection
✔ An integrated, adjustable handhold
✔ Added protection during ladder-to-platform access
✔ Configurations for different applications and operating environments
✔ A system tested relevant fall-restraint and fall-arrest requirements

Because water truck safety isn’t only about what happens on the haul road.

It’s also about protecting the people who inspect, maintain and keep that equipment running.

🦺 SAFETY BY DESIGN | PART 4

Safer equipment should make the operator’s job easier…not harder.

Since 2020, MSHA has reported 129 accidents involving contract truck drivers at mining operations, resulting in 5 fatalities and 99 lost-time injuries.

It’s a reminder that heavy equipment safety depends on more than what happens behind the wheel. The equipment itself should support safe, predictable operation.

For a water truck, that includes giving operators better control over how and when water is applied.

Klein helps put that control within reach through:
✔ SmartControl® for an intuitive operator interface
✔ SmartSpray® for independent water pump control
✔ Precision Flow Control baffling to help manage water movement
✔ Spray systems designed for controlled water application

Why does that matter?
Too little water can leave dust in the air and reduce visibility. Too much can contribute to muddy or slippery road conditions.

The goal isn't simply to put water on the ground. It's to give operators the control to put the right amount where it's needed.

🦺 SAFETY BY DESIGN | PART 3

When thousands of gallons are shifting back/forth, up/down, right/left… STABILITY matters.

Between 2018 and 2024, MSHA documented 42 tipping or rollover injury incidents involving trucks during work operations:
• 14 involving over-the-road style trucks
• 28 involving off-road mine haul trucks

Water trucks face an added challenge: water is a dynamic load. As a truck accelerates, brakes, turns or travels across uneven terrain, the water payload shifts with it.

That makes weight distribution and payload containment/control critical.

Klein addresses these challenges through:
✔ TRAP Tank Technology™ with a lower center of gravity
✔ Effective weight distribution across the chassis
✔ Precision Flow Control baffling to contain water movement
✔ Tank and mounting systems engineered to support predictable handling

You can’t control the terrain…but you can engineer the truck to handle it better.

🦺 SAFETY BY DESIGN | PART 2

23 fatalities. One risk no operator can afford to overlook: visibility.
Mine Safety and Health Administration (MSHA) has reported at least 23 fatalities since 2003 involving large mobile equipment striking smaller vehicles, with restricted visibility and blind spots identified as concerns in these types of incidents.

On an active mine or construction site, operators are constantly watching for people, vehicles, equipment and changing conditions.

What they can see matters.

That's one reason Klein's patented TRAP Tank Technology™ is designed with visibility in mind. Its unique tank geometry features a narrower top profile that helps improve operator sightlines around the truck.

And that's just one part of the picture.

Klein water trucks can also incorporate multiple tools to support operator awareness:
👁 Front, side and rearview camera systems
💡 Work lights for low-light operating conditions
🔶 Reflective tape for increased equipment visibility

Safety isn't one component or one checklist.

It's giving operators equipment designed to help them stay aware of what's happening around them.

Visibility matters. Awareness matters. People matter.

🦺 SAFETY BY DESIGN | PART 1

A water tank isn't just something you put on the back of a truck.

Its design changes how the truck behaves.

Thousands of gallons of water create a dynamic load. As the truck accelerates, brakes, turns and travels across uneven terrain, tank geometry and water movement can influence stability, weight distribution and handling. Not to mention wear and tear on the truck chassis.

That’s where Klein’s TRAP Tank Technology™ comes in.

Its engineered trapezoidal geometry is designed around the physics of carrying water:
✔ Lower center of gravity for improved vehicle balance
✔ Effective weight distribution across the chassis
✔ Precision Flow Control baffling to manage water movement
✔ More predictable handling during acceleration, steering and braking

The result is a tank system designed to work with the chassis—not simply ride on top of it.

Safety isn't just about how equipment is operated. It starts with how equipment is engineered.

A reliable fleet manager often looks invisible when things are going well.

🔹 No crisis.
🔹 No drama.
🔹 No emergency meeting.
🔹 No frantic phone calls.

Just steady ex*****on.

That can make reliability look easy. It isn’t.

It’s the result of good decisions made before the problem shows up.

That’s why uptime is respect.

You earn it quietly.

There’s a big difference between asking customers what they want and understanding what they need.

Customers may ask for:
More capacity.
More spray.
More control.
Faster turnaround.

But underneath those requests are usually something deeper:
Less downtime.
Less stress.
More predictability.
More confidence.

The best solutions come from understanding the problem behind the request.

That’s where better engineering begins.
