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!
