Скачать или смотреть CRITICAL Step: Why Crane Outriggers are a Lifesaver: Watch a Pro Operator Stabilize a Mobile Crane

Balance, spread, and certainty the lift is decided before the boom moves.

This video highlights the critical step of deploying crane outriggers, showing how a professional operator stabilizes a mobile crane in seconds. Outriggers don’t add power they create safety by widening the crane’s stance and managing ground pressure. What looks routine is actually the foundation of every successful lift.

The Process
Site Read and Positioning:

The crane is positioned on the most level, load-bearing ground available.

Overhead and underground hazards are identified and cleared.

The lift radius and swing path are visualized before setup begins.

Outrigger Inspection:

Outrigger beams, cylinders, and pins are visually checked.

Pads or mats are selected to suit soil or pavement conditions.

Controls are confirmed responsive before extension.

Extension and Spread:

Outriggers are extended outward to their specified width.

Each beam is locked to prevent retraction under load.

The crane’s footprint expands to distribute forces safely.

Pad Placement:

Pads are centered beneath each outrigger foot.

Contact surfaces are kept flat and clean.

Ground pressure is spread to prevent sinking or shear failure.

Leveling Sequence:

Hydraulic pressure is applied incrementally to each outrigger.

The crane chassis is leveled using onboard indicators.

Adjustments are made gradually to avoid twisting the frame.

Stability Confirmation:

All outriggers are rechecked for equal load sharing.

The crane is lifted slightly to confirm solid footing.

Only after confirmation does boom movement begin.

Why This Works:

✔ Wider Base: Increased stance dramatically improves stability.
✔ Load Distribution: Pads reduce ground pressure and settlement.
✔ Frame Integrity: Proper leveling prevents structural stress.
✔ Predictable Behavior: A stable crane responds smoothly to inputs.
