Camera on the crane. Passive target on the hook block. Nothing else.
No electronics or moving parts on the hook. No mechanical wear. No calibration drift.
Works for any reeving arrangement on any hoist type.
Overview
Side pulls and snag events are among the most damaging things that can happen to an overhead crane and its load. A snag can happen in seconds — a hook catches on a load or structure, the hoist continues, and thousands of pounds of force are applied where they should never be. craneIQ Vision watches the hook continuously and stops these events before damage occurs. The system uses a camera mounted on the crane structure and a simple passive target on the hook block — no electronics, no moving parts, nothing to calibrate or maintain on the hook itself. Because it is camera-based rather than sensor-based, it works regardless of reeving arrangement — single fall, double fall, or any other configuration. In the field, craneIQ Vision has prevented real snag and side pull incidents that would otherwise have caused significant crane and load damage.
How it works
01 — Camera
Mounted on the crane structure
An IP67 rated camera sits on the crane bridge or end carriage — fixed, protected, and well away from the load. Nothing moves, nothing wears.
02 — Target
Passive target on the hook block
A simple passive target attaches to the hook block — no electronics, no power supply, no moving parts. Nothing to calibrate. Nothing to maintain. Works on any reeving arrangement.
03 — Detection
Continuous real-time monitoring
The camera tracks the target position continuously. The moment it detects the hook moving outside the safe envelope — side pull, snag, or misalignment — it intervenes in under 20ms.
What it does for you
- Prevents side pull eventsDetects when the hook is not directly below the hoist and stops the lift before angled loading damages the crane
- Prevents snag eventsContinuously monitors hook position — issues a stop command the moment a snag is detected
- Works for any reeving arrangementSingle fall, double fall, or any configuration — camera-based detection is unaffected by how the rope is rigged
- Proven in the field — incidents preventedcraneIQ Vision has stopped real snag and side pull events on working cranes, preventing significant damage
- Auto hook centringAutomatically drives the crane to position the hook directly above the load before hoisting — no operator judgment needed
- Nothing to maintain on the hookPassive target only — no electronics, no battery, no moving parts, no calibration schedule
- IP67 camera for harsh environmentsSealed against dust, moisture and chemical fumes — proven in galvanizing plants and steel mills
- Fits any crane, any ageMounts on the crane bridge or end carriage — no structural changes required
