The Problem

Overhead crane operations create massive blind spots directly below the equipment. Dropped loads and unsafe proximity to personnel in hazard zones cause fatal incidents.

Massive blind spots — Crane operators cannot see directly below. Large overhead areas remain invisible even with mirrors and cameras installed. No visibility of ground personnel.
Dropped load zones — Critical areas below crane paths vulnerable to dropped loads. No real-time indication if personnel are in danger zones. Manual spotters are unreliable.
Pedestrians beneath cranes — Personnel working under crane operation areas face serious risk without system protection or awareness. High-consequence incident zones.
No real-time tracking — No system to track personnel position relative to crane load. Operators unaware of critical proximity situations. Static safety zones are insufficient.

How It Works

Personnel Tags

Personnel wear lightweight UWB tags. Tags transmit unique identification and location signals continuously during operation.

UWB Detection

UWB receiver nodes mounted on crane detect tag proximity. Real-time positioning accurate to sub-meter levels. 360° coverage area.

Alert or Control

MPAS model triggers audible alerts when personnel too close. MPCS model automatically restricts crane movement when danger detected.

Continuous Tracking

Complete position tracking under crane path. Operators see real-time personnel location dashboard. Safety audit logs maintain compliance.

Key Features

360° Under-Crane Coverage

Comprehensive detection across entire area beneath crane operation. Omnidirectional monitoring with no blind spots.

Tag-Based Tracking

Personnel wear compact UWB tags. Real-time positioning with sub-meter accuracy. Unique ID tracking for individual personnel.

MPAS/MPCS Models

MPAS for alert-only deployment. MPCS for automatic crane control. Choose model based on operational requirements.

0.2-30m Range

Extended range from near-field (0.2m) to 30-meter coverage. Covers all typical overhead crane operational areas.

Harsh Environment Rated

IP65 rated components. Operates in extreme temperatures, moisture, dust, and electrical noise of industrial environments.

Charging Station for Tags

Integrated charging dock for personnel tags. Quick-charge capability for shift operations. Long battery life per charge.
