Crane Operator Safety

Crane operators control one of the most dangerous pieces of equipment on any construction site, requiring constant vigilance.
Operators must hold a valid CPCS or NPORS card specific to the crane type: mobile, tower, crawler, or loader crane.
The crane must not be operated beyond its rated capacity at any radius — the load moment indicator is a critical safety system.
Pre-shift checks must cover outriggers, wire ropes, sheaves, brakes, slew, hoist, boom condition, and all safety devices.
Communication with the slinger/signaller must be maintained throughout every lift using agreed, standard hand signals or radio.
Wind speed must be monitored continuously — most mobile cranes must cease operations when wind exceeds 38 mph.
The crane operator is responsible for refusing an unsafe lift, regardless of pressure from supervisors or programme demands.
Outrigger setup is critical for mobile cranes — all legs must be fully extended on firm ground with adequate spreader plates.
Tower crane operators work at extreme heights in isolation — welfare, communication, and emergency rescue must be arranged.
Fatigue management is essential — crane operations require sustained concentration that deteriorates over long shifts.

Overload prevention	Exceeding the crane's rated capacity causes structural failure and load drop — the operator must check the load chart for every lift.
Operator authority	The crane operator has the final say on whether a lift proceeds — no one may override this decision for programme or production reasons.
Isolation and fatigue	Crane operators work alone at height for long periods — fatigue degrades the concentration needed for safe lifting operations.

Do

Don't

Hold a valid CPCS or NPORS card for the specific crane type you operate.
Check the load chart for every lift — verify weight, radius, and boom configuration.
Complete the full pre-shift inspection before starting any lifting operations.
Maintain communication with the slinger/signaller throughout every lift sequence.
Monitor wind speed continuously and stop lifting when the crane limit is reached.
Refuse any lift you believe is unsafe — this is your right and responsibility.
Set up outriggers fully on firm ground with spreader plates before lifting.
Take regular breaks to manage fatigue during long shifts in the crane cab.
Follow the rescue plan and ensure communication equipment is working at all times.
Report any wire rope damage, brake issues, or safety device faults immediately.

DON'T operate any crane type without a valid CPCS or NPORS card for that category.
DON'T lift any load without checking the load chart for the current configuration.
DON'T start lifting without completing the daily pre-shift inspection thoroughly.
DON'T carry out lifts without clear, continuous communication with the signaller.
DON'T continue lifting operations when wind speed exceeds the crane's rated limit.
DON'T feel pressured into making a lift you believe is unsafe — always refuse.
DON'T operate a mobile crane with outriggers only partially extended or on soft ground.
DON'T work through exhaustion — fatigue causes the errors that lead to dropped loads.
DON'T work at height in a tower crane without a functioning communication system.
DON'T ignore warning alarms from the load moment indicator — they indicate overload.
