A trench box does not have one universal maximum depth. Its allowable depth depends on soil conditions, trench depth, surcharge loads, and the manufacturer’s tabulated data. A box that can be used deeper in stable soil may have a much lower...

Pneumatic vs. Electric Zero-Gravity Balancers: Which Technology Fits Your Operation?
The biggest difference between a pneumatic and electric balancer is not what the operator feels. Both can make a heavy part feel nearly weightless. Both can reduce the effort behind repetitive lifting. Both can improve control at the workstation....
Exoskeletons vs. Lift Assist Devices: Which Technology Actually Reduces the Load?
Industrial exoskeletons get attention for a good reason. They are wearable, increasingly sophisticated, and can reduce physical demand during certain repetitive or awkward tasks. NIOSH research has found that some exoskeletons can reduce muscle...
Hydraulic Shoring Maintenance: Troubleshooting Leaks, Seals, and Pressure Drops
A hydraulic shore that will not hold pressure is not something to “see how it does” on the next job. It stays in the yard. For fleet mechanics, equipment managers, and shop foremen, hydraulic shoring maintenance comes down to a few failure points...
The Part Passed Inspection. Then Someone Picked It Up.
The coating was clean. The dimensions were in tolerance. The surface passed inspection. Then the part was lifted, shifted, rotated, and placed into the next fixture. That is where the scratch appeared. Manufacturers invest heavily in controlling...
Sunshine, Laughter, and a Day With the KUNDEL Family
We recently traded the workday for sunshine at our company picnic at Pioneer Waterland. Employees and their families spent the day racing down water slides, floating along the lazy river, playing mini golf and cornhole, riding go-karts, and...
Deep Trenching Safety: Best Practices for Stacking Trench Boxes
Deep trench work does not reward shortcuts. When excavations reach 16, 20, or more feet deep, crews often need to stack trench boxes to create a protected work zone for sewer, utility, and heavy civil applications. On paper, the concept is simple:...
Vacuum vs. Mechanical vs. Magnetic Grippers: Choosing the Right End Effector
Choosing the right lift assist system starts with one practical question: How should the equipment actually grip the part? The crane, jib arm, or balancer moves the load. The end effector secures it. That makes the gripper one of the most important...
Slope It, Shore It, Shield It: What KUNDEL Took From Cincinnati’s Trenching Safety Summit
On April 15, 2026, contractors, safety professionals, and heavy civil construction crews gathered in Cincinnati for the “Slope It, Shore It, Shield It” Trenching and Excavation Compliance Summit. The free in-person seminar, organized by the OSHA...
