Multi-Level Collision Avoidance System

INTRODUCTION

Anti-collision solution for cranes operating at different heights, designed to monitor crane and hook positions in real time and apply coordinated slowdown/stop interlocks when unsafe proximity is detected.

Key Features

  • Detection -Real-time sensing of crane and hook positions
  • Control Range – 5-10m approach zone for slowdown and stop
  • Safety Logic -Hook upper-limit aware collision decisions
  • Deployment: Supports coordinated upper/lower bay cranes

System Coverage

multi-Level collision avoidance system
  • Continuous position sensing of all cranes on upper and lower bays
  • Coordinated interlocks for slowdown and stop across approaching cranes
  • Real-time hook position monitoring integrated into collision logic
  • Designed for multi-crane operations on shared runway spaces

Key Benefits

  • Reduces collision risk in cranes operating at different levels
  • Enforces predictable movement behavior near critical zones
  • Improves operational safety in dense multi-crane environments
  • Supports safer synchronization between top and bottom bay cranes.

Reference Installation

  • Crane 1: Top bay, bay length 100m, span 29m
  • Crane 2: Top bay, bay length 100m, span 29m
  • Crane 3: Bottom bay, bay length 80m, span 8m
  • Crane 4: Bottom bay, bay length 80m, span 8m

Principle of Operation

  • The system continuously tracks all crane positions and hook position status.
  • When cranes approach within a 5-10m range, slowdown and stop logic is evaluated.
  • If the upper-bay crane hook is not at upper limit, both upper and lower bay cranes are slowed/stopped when approaching unsafe proximity.
  • If the upper-bay crane hook is at upper limit, approaching cranes can continue without slowdown/stop for that condition.
