Tower cranes are indispensable in modern construction, but they also present significant risks if not operated and maintained correctly. At UNIQUEMAC, we believe in proactive tower crane safety procedures.

Essential Safety Procedures for Tower Crane Operation

Load Capacity Verification

Always check the weight of the load before lifting. Exceeding the crane’s rated capacity can cause structural failure or tipping.

 

Wind Speed Monitoring

Use an anemometer to monitor wind. Do not operate if wind speeds exceed manufacturer limits—typically enforced to prevent crane instability.

 

Overhead Power Line Safety

Maintain safe clearance from overhead lines—20 ft below 350 kV, 50 ft above, per ASME B30.3 standards. Implement qualified utility spotters when working near lines.

 

Site and Ground Condition Evaluation

Inspect ground stability, levelness, and look for potential obstructions before setup. This ensures a secure base and prevents tipping.

 

Exclusion Zones

Establish exclusion zones around crane operations. Prevent unauthorized personnel from entering swinging or suspended load areas.

 

Rigging and Hook Inspection

Inspect hooks, wire ropes, and rigging gear for wear, corrosion, crack, and ensure safety latches are functional. Worn rigging can lead to catastrophic load drops.

 

Safety Device Testing

Ensure all operational aids function, including:

Anti two-blocking

Boom/radius limiters

Trolley end stops

These are vital per OSHA 1926.1435. When disabled, mark cables visibly or use spotters.

Communication Protocols

Use standardized signals and designate trained spotters. Reliable communication helps coordinate movements and prevent accidents.

 

Operator Training & Competency

Operators must be deemed “competent persons” — trained to identify hazards and stop unsafe operations. Licenses and documented training are essential.

 

How do you checklist of crane safety?

A structured crane safety checklist ensures consistency and helps catch potential issues before they escalate. Here's a standard format suitable for UNIQUEMAC documents:

 

a) Pre-Operational (Daily / Pre-Shift)

Ground conditions: level, firm, clear of debris

Wind speed reading: within safe operational limits

Load chart visibility and correctness

Hook, wire ropes, sheaves, trolleys: no wear, corrosion, deformation

Operational controls: slewing, hoisting, trolley free movement

Safety devices: limiting switches, brakes, anti two‑blocking, overload indicators

Communication devices and spotters are in place

Area and exclusion zones are clear

Cab: visibility, load charts, windows, fire extinguisher

 

b) Weekly / Monthly

Structural integrity: mast, jib joints, fasteners

Slewing ring & bearings: wear, lubrication, torque

Counterweight security and base-frame anchoring bolts

Electrical wiring: secure, undamaged, grounding present

Brakes and gears: oil levels, mechanical functionality

Limit switch operations and calibration

Safety latches, hooks, pulleys, ropes thoroughly examined

 

c) Periodic / Annual Inspections

Full mechanical / electrical evaluation by competent inspector per OSHA 1926.1412

Load testing as per site-specific engineering requirements

Foundation and support anchorage verified to manufacturer specs

Safety device certification; replacements or repairs within specified timeframes

Maintenance & Preventive Care

Visual Inspection: Spot cracks, corrosion, misalignment.

Lubrication: Grease slewing gear, Jib sections, wire rope pulleys.

Brake Systems: Check and adjust mechanical and hydraulic brakes.

Limit Switch Testing: Simulate limits to ensure function.

Rope Maintenance: Inspect for kinks, broken strands, keep tension correct.

Electrical Systems: Inspect wiring, connections, control panels.

Safety Devices: Verify anti‑collision, load, and wind‑speed monitoring systems.

Daily visual checks and scheduled periodic inspections “ensure safety, efficiency, and longevity” of tower cranes.

Environmental & Operational Hazards

Wind & Weather: Do not operate under strong wind, storms, ice, or lightning. Component vulnerabilities increase.

Heat Stress: Crane cabs may overheat; maintain hydration, especially above 26 °C.

Power Lines: Treat all overhead lines as energized. Maintain clearance and use spotters until de‑energized and grounded.

 

Anti-Collision and Advanced Safety Systems

Where multiple tower cranes operate, anti-collision systems can prevent crane-to-crane contact by slowing or stopping movement when approaching a defined zone. Operators receive zoning and situational alerts in real time.
