In Canada, overhead crane owners and operators are legally required to follow strict safety standards outlined by the Canadian Standards Association (CSA) and provincial Occupational Health and Safety (OH&S) regulations. Ignoring early warning signs can not only lead to expensive downtime—it could result in regulatory violations or serious injury.

Here are the top 5 signs your overhead crane needs immediate professional attention:

🚨 1. Unusual Noises During Operation

Hearing grinding, clanking, or screeching from your crane? That’s not normal. These sounds may signal:

• Gearbox or motor issues

• Misaligned components

• Lack of lubrication

CSA B167 requires that hoisting equipment be kept in sound mechanical condition, and noise is a key indicator.

⚠️ 2. Jerky or Irregular Movements

Smooth, controlled motion is essential. If your crane:

• Hesitates

• Lurches unexpectedly

• Stops abruptly

…it may have a faulty VFD, control issue, or worn mechanical part, all of which can breach OH&S safety standards.

🧯 3. Frayed or Damaged Wire Ropes

This is a critical safety issue in all Canadian provinces. Wire ropes must be visually inspected and taken out of service if:

• There are six or more broken wires in one rope lay

• There’s birdcaging, corrosion, or flattening

CSA B167 mandates removal and replacement under these conditions.

🛑 4. Malfunctioning Limit Switches

Limit switches stop a crane from lifting too high or traveling too far. If they fail, it can cause:

• Load drops

• Collision with end stops

• Over-travel and structural damage

Malfunctioning switches violate CSA and OH&S requirements and should be addressed immediately.

🧰 5. Oil Leaks or Overheating

Oil leaks near motors, gearboxes, or brakes may indicate:

• Seal failure

• Overheating

• Impending mechanical failure

Thermal degradation and fluid loss are hazards that increase wear and reduce operational safety.
