Height and Slew Safety : What It Is and Why It Matters on Every Site

When it comes to operating heavy machinery safely and compliantly, height and slew limitations are essential site controls that protect workers, structures, and underground services.

At ZELVi Equipment, we’re serious about keeping your job site safe. Here’s what you need to know about height and slew restrictions, and why your next hire should factor them in.

What Are Height and Slew Limitations?

Height limitations refer to the maximum vertical distance a machine can reach or operate within, typically put in place to avoid contact with overhead powerlines, structures or canopy protection zones.

Slew limitations restrict how far a machine’s upper structure (like an excavator body) can rotate left or right. This is especially important when working in tight spaces or near no-go zones like roadways, railway corridors or neighbouring properties.

Why Are Height and Slew Limitations Important?

Protect People & Property
Uncontrolled movement can pose serious risks to workers and the surrounding infrastructure. Limiting the range of motion helps eliminate collisions and any problems.

Avoid Costly Damage
Slewing into fences, utility poles or existing structures can lead to thousands in damage, and downtime.

Stay Compliant
Many job sites, especially in civil construction and infrastructure, require strict height and slew restrictions to meet local safety regulations and project-specific requirements.

Safe Work Near Live Services
Operating near overhead or underground services? These limits are a must to ensure you don’t breach exclusion zones.
