Bagaimana cara melakukan vehicle marshalling yang aman?

Vehicle Marshalling adalah penggunaan banksman/spotter untuk guide vehicle atau heavy equipment movement di area dengan limited visibility atau high traffic.

Kapan Marshalling Required:

• Backing/reversing - operator blind spot paling besar
• Confined space maneuvering
• High pedestrian traffic area
• Loading/unloading operation
• Crossing busy access road
• Any time visibility compromised

Banksman/Spotter Requirements:

Qualification:

• Trained di standard hand signal
• Understand equipment capability dan limitation
• Good communication skill
• Minimum 18 tahun, physically fit

Equipment:

• High-visibility vest (bright orange/yellow)
• Signal batons (preferred) atau hand signal
• Radio untuk 2-way communication dengan operator
• Whistle untuk emergency stop signal

Positioning:

• Always visible to operator - within mirror/direct sight
• Safe position - never di path of travel atau swing radius
• Clear of pinch points - tidak antara vehicle dan struktur

Standard Hand Signals:

• Move Forward: Arms extended, palms up, wave toward body
• Move Back: Arms extended, palms out, push motion
• Turn Left/Right: One arm extended, pointing direction
• Stop: Arm raised, palm facing operator (or fist)
• Emergency Stop: Both arms raised, rapid crossing motion
• Slow Down: Arms extended, palms down, slow lowering motion

Communication Protocol:

Radio (Preferred for Noisy Environment):

• Clear, specific instruction: "Reverse 3 meters, slowly"
• Operator acknowledge: "Reversing 3 meters, slowly"
• Continuous updates: "2 meters remaining... 1 meter... Stop"

Operator Responsibilities:

• ONLY move when banksman visible dan signal clear
• If lose sight dari banksman - STOP immediately
• Acknowledge signals (horn toot atau radio)
• Override authority: Operator can refuse unsafe instruction

Banksman Responsibilities:

• Continuous 360° awareness - watch untuk hazards
• Clear path checked sebelum signal movement
• Anticipate issues - stop sebelum problem occurs
• Emergency stop if ANY doubt

Common Mistakes to Avoid:

• Multiple spotters giving conflicting signals - designate ONE only
• Banksman posisi berbahaya - crushed between vehicle-wall
• Operator proceed saat banksman tidak visible
• Unclear signals - rushing, ambiguous gestures

Proper marshalling prevents 40% of vehicle collision incidents!
