Excavator Bench Setup and Operator Safety
In earthmoving operations, a bench refers to the horizontal surface or ledge cut into a slope or embankment to provide a stable working platform for heavy equipment. Excavator operators rely on benches to position their machines safely while digging, loading, or grading. When a bench is improperly cut—either too high, too narrow, or too steep—it can compromise machine stability, increase the risk of rollover, and reduce operational efficiency.
In one widely circulated video, an excavator perched precariously on a slope attempts to maneuver without a proper bench. The result is a chaotic rescue attempt involving multiple machines, uncoordinated personnel, and near-disaster. The footage underscores a simple truth: bench height and width are not optional—they are foundational to safe excavation.
Terminology Notes
In Brazil, a crew attempted to recover an excavator that had slipped off a poorly cut bench. Instead of repositioning the support truck or coordinating movements, multiple operators acted independently. One machine pushed on the drive motor, another attempted to lift the boom, and a third operator jumped into the disabled cab. The lack of communication and planning turned a minor recovery into a dangerous spectacle.
A similar incident occurred in upstate New York, where an excavator slid down a frost-covered bench during early spring thaw. The operator had skipped bench preparation due to time pressure. The machine was recovered safely, but the repair bill for track damage exceeded $12,000.
Recommendations for Operators and Supervisors
Bench height and geometry are critical to safe and efficient excavator operation. Cutting corners—literally or figuratively—can lead to equipment damage, injury, or costly delays. Whether you're building access roads, trenching, or mass grading, take the time to prepare a proper bench. It’s not just good practice—it’s essential engineering.

Terminology Notes
- Bench: A flat working surface cut into a slope to support equipment.
- Drive Motor: The hydraulic motor that powers the excavator’s tracks.
- Tracking Levers: Controls used to move the excavator forward or backward.
- Cutting Too High: A bench that leaves the machine’s center of gravity above the slope line increases rollover risk.
- Insufficient Width: Narrow benches don’t allow full track contact, leading to slippage or tipping.
- Ignoring Drainage: Water pooling on benches can soften soil and undermine stability.
- Poor Access Planning: Without a clear path to enter or exit the bench, machines may become trapped or require risky maneuvers.

Recommendations for Operators and Supervisors
- Cut Benches at or Below Track Level: Ensure the machine sits with full track contact and a low center of gravity.
- Use a Spotter During Setup: A second set of eyes can catch slope irregularities or soft spots.
- Coordinate Recovery Efforts: Assign roles and communicate clearly before attempting to move disabled equipment.
- Train Operators on Bench Geometry: Include bench setup in safety briefings and operator certification programs.
- Inspect Bench Conditions Daily: Weather, traffic, and excavation progress can alter bench integrity.
