Crane and Lifting Equipment Safety for Safe and Efficient Operations

What Is Crane and Lifting Equipment Safety?

Crane and lifting equipment safety is the controlled process of selecting, inspecting, planning, and operating cranes, hoists, rigging equipment, and lifting accessories without exposing workers, loads, equipment, or property to unacceptable risk.

It depends on competent personnel, verified load information, suitable lifting equipment, effective communication, appropriate supervision, and compliance with applicable legislation, standards, site procedures, and manufacturer instructions.

Legal requirements vary between jurisdictions. OSHA requirements apply primarily to workplaces in the United States, LOLER applies in Great Britain, and ISO standards may be adopted voluntarily or incorporated into national regulations, contracts, and organisational procedures. Businesses must therefore identify the rules that apply to each lifting operation.

Why Do Safety and Efficiency Belong Together?

Effective safety controls reduce the likelihood of equipment damage, load instability, unplanned stoppages, rework, near misses, emergency maintenance, and communication failures.

Efficiency does not mean completing a lift faster. It means carrying out the operation correctly, predictably, and without avoidable interruptions.

Safe and efficient lifting operations can improve productivity while protecting workers, equipment, property, and business continuity. When lifting activities are properly managed, crane safety and operational efficiency work together to reduce downtime and unnecessary costs.

Which Cranes and Lifting Equipment Are Covered?

This article covers:

• Mobile cranes
• Tower cranes
• Crawler cranes
• Overhead and gantry cranes
• Truck-mounted cranes
• Hoists and winches
• Wire-rope, chain, and synthetic slings
• Shackles and hooks
• Lifting beams and spreader beams
• Other below-the-hook lifting devices

The appropriate controls depend on the equipment, load, lifting configuration, operating environment, and applicable jurisdiction.

For construction work in the United States, OSHA’s Cranes and Derricks in Construction standard, 29 CFR 1926 Subpart CC, applies to many types of power-operated equipment used to hoist, lower, and horizontally move suspended loads.

What Are the Most Common Crane and Lifting Hazards?

Overloading and Incorrect Load Calculations

Unknown load weight, incorrect load estimates, misread load charts, increased lifting radius, unaccounted rigging weight, and incorrect crane configuration can all contribute to overloading.

The lifting team must never assume the weight of a load or the available crane capacity. Before the operation begins, it should verify:

• Load weight
• Rigging and accessory weight
• Lifting radius
• Boom configuration
• Counterweight arrangement
• Crane level
• Load-chart restrictions
• Applicable capacity reductions

Crane Instability

Weak or uneven ground, inadequate ground-bearing capacity, poor outrigger positioning, underground services, hidden voids, excessive lifting radius, side loading, and wind exposure can cause crane instability.

The planning process should assess ground conditions and determine whether mats, spreader plates, engineered foundations, or other load-distribution measures are required.

Outriggers should be positioned and extended according to the manufacturer’s instructions and the selected crane configuration.

Rigging or Equipment Failure

Damaged slings, incorrect sling angles, worn wire ropes, distorted hooks, improperly secured shackles, unrated lifting accessories, and missing identification markings can lead to rigging or equipment failure.

All lifting accessories should be inspected before use. Equipment showing damage, excessive wear, deformation, illegible identification, or other rejection criteria should be immediately removed from service and assessed by an authorised competent person.

Struck-By, Crushing, and Electrical Hazards

Suspended loads, crane swing areas, pinch points, blind lifts, uncontrolled load movement, overhead power lines, and workers entering lifting exclusion zones create serious struck-by, crushing, and electrical hazards.

Businesses should establish clearly defined exclusion zones, control access, plan the load path, and maintain safe clearance from electrical hazards.

No worker should stand or pass beneath a suspended load unless a specific regulation permits the activity and all required protective measures have been implemented.

How Should a Safe Lifting Operation Be Planned?

A six-step planning framework can help organisations control lifting risks.

Step 1: Define the Lift

Confirm the:

• Load weight
• Load dimensions
• Centre of gravity
• Lifting points
• Pick-up and landing locations
• Load travel path
• Required lifting radius
• Required lifting height
• Potential for load rotation or shifting

All critical information should be verified and documented before selecting the crane and rigging arrangement.

Step 2: Select Suitable Equipment

Verify the crane configuration, rated capacity, applicable load-chart limitations, rigging capacity, working load limits, and required safety devices.

The selected equipment must be capable of safely handling the load throughout the entire lifting path—not only at the initial pick-up point.

The plan should account for changes in radius, boom angle, load position, and crane configuration during the lift.

Step 3: Assess the Environment

Assess:

• Ground conditions
• Underground services and voids
• Overhead power lines
• Wind speed and direction
• Rain, lightning, snow, ice, or extreme temperatures
• Visibility and lighting
• Nearby structures
• Traffic and pedestrian movement
• Simultaneous site activities
• Restricted working areas

Weather and environmental limits should follow manufacturer instructions, engineering requirements, and applicable site procedures.

Step 4: Identify People and Responsibilities

Depending on the complexity of the operation, responsibilities may be assigned to:

• Lift planner or appointed person
• Lifting supervisor
• Crane operator
• Rigger or slinger
• Signal person
• Spotter
• Competent equipment inspector
• Site or project manager

Clear role definition prevents confusion and ensures that responsibility and decision-making authority are understood.

Step 5: Establish Controls

The lift plan should address:

• Exclusion-zone boundaries
• Crane swing-radius protection
• Communication methods
• Radio channels and backup signals
• Tag-line arrangements
• Power-line controls
• Emergency procedures
• Stop-work authority
• Permit-to-lift requirements
• Weather limits
• Load-control arrangements
• Contingency measures

These controls form the operational foundation of a safe lift.

Step 6: Conduct a Pre-Lift Briefing

Everyone involved should understand:

• The lift plan
• Their individual responsibilities
• The lifting sequence
• The load path
• The communication method
• The approved hand or radio signals
• The exclusion-zone requirements
• The emergency arrangements
• The conditions requiring the lift to stop

The Health and Safety Executive’s LOLER guidance states that lifting operations in Great Britain must be properly planned by a competent person, appropriately supervised, and carried out safely.

The complexity and detail of the plan should reflect the risks and complexity of the lifting operation. A routine lift may require a relatively simple documented plan, while a critical, tandem, blind, or technically complex lift may require engineering input and extensive supervision.

Safe lifting therefore begins long before the operator touches the controls. It starts with planning, verified competence, equipment inspection, risk assessment, and clear communication.

What Inspections Are Required Before Lifting?

Pre-Use or Pre-Shift Checks

Pre-use or pre-shift checks may include:

• Operating controls
• Service and parking brakes
• Safety devices
• Operational aids
• Hooks and safety latches
• Wire ropes and reeving
• Hydraulic systems
• Outriggers and stabilisers
• Alarms and indicators
• Tyres, tracks, or supporting structures
• Visible structural damage
• Fluid leakage
• Load-moment or rated-capacity indicators

Any defect affecting safe operation should be reported, and the equipment should not be used until the defect has been assessed and corrected.

Rigging and Lifting-Accessory Checks

Before use, inspect:

• Wire-rope slings
• Chain slings
• Synthetic web or round slings
• Shackles
• Hooks
• Master links
• Lifting clamps
• Eyebolts
• Lifting beams
• Spreader beams
• Identification tags
• Working load limit markings

The inspection should confirm that the equipment is suitable for the load, lifting method, environment, and proposed sling angles.

Periodic and Post-Event Inspections

More detailed inspections or examinations may be required:

• At specified legal or manufacturer intervals
• After repairs or modifications
• Following overload or shock loading
• After a collision
• After equipment has been out of service
• Following severe weather
• After suspected structural or mechanical damage
• When deterioration could create danger

Under OSHA’s construction-crane requirements, a competent person must begin a visual inspection before each shift, while additional monthly and annual or comprehensive inspections may also be required.

ISO 9927-1:2013, Cranes — Inspections — Part 1: General provides general requirements for crane inspections. The standard was reviewed and confirmed in 2023 and remains current.

Inspection requirements must always be based on the applicable legislation, manufacturer instructions, equipment type, operating conditions, and findings from previous examinations.

Who Must Be Competent to Participate in a Lift?

Roles that may require demonstrated competence include:

• Crane operator
• Rigger or slinger
• Signal person
• Lifting supervisor
• Lift planner or appointed person
• Competent inspector
• Maintenance personnel
• Spotter

Competence should reflect the person’s training, knowledge, practical experience, understanding of equipment limitations, and ability to recognise and control risks.

A certificate alone may not prove competence for every crane type, load, configuration, or worksite.

For construction cranes covered by OSHA Subpart CC, employers must ensure that operators are appropriately trained, certified or licensed where required, and evaluated for the equipment and work they are assigned to perform, subject to the standard’s scope and exceptions.

Online learning can support theoretical knowledge, but it does not replace equipment-specific practical instruction, supervised experience, employer evaluation, or legally required certification and licensing.

How Should the Lifting Operation Be Controlled?

A controlled lifting operation should generally follow this sequence:

1. Establish and barricade the crane swing radius and lifting exclusion zone.
2. Confirm that the crane is level, stable, and correctly configured.
3. Verify ground support, outrigger placement, and load-distribution measures.
4. Complete the pre-lift meeting and final equipment checks.
5. Confirm that the load is correctly rigged and that lifting points are suitable.
6. Perform a controlled test lift, where appropriate.
7. Check load balance, rigging security, brakes, clearance, and crane stability.
8. Confirm that the communication system is functioning.
9. Move the load slowly and avoid shock loading or sudden acceleration.
10. Keep workers clear of suspended loads and potential pinch points.
11. Continuously monitor weather, visibility, ground conditions, and equipment behaviour.
12. Stop the operation if communication, stability, visibility, weather, equipment condition, or load control becomes unsafe.
13. Land and secure the load before releasing tension or disconnecting the rigging.

The crane operator should normally receive instructions from one designated signal person. However, a stop or emergency-stop signal must be obeyed regardless of who gives it.

OSHA publishes recognised standard crane hand signals in Appendix A to Subpart CC. Where hand signals are used, the signal person and operator should understand the agreed signal system before the lift begins.

How Can Businesses Improve Lifting Efficiency Safely?

Businesses can improve efficiency through better preparation and coordination. Useful measures include:

• Standardised lift-plan templates
• Digital lifting-equipment registers
• Inspection-status tags linked to traceable records
• Planned crane positioning
• Early confirmation of load weights
• Coordinated delivery schedules
• Preventive maintenance
• Pre-engineered or approved rigging configurations
• Standard communication protocols
• Spare equipment planning
• Near-miss trend analysis
• Post-lift reviews
• Clear equipment quarantine procedures

Colour codes or inspection tags should not be treated as proof that equipment is safe. They should be supported by identifiable equipment records, inspection dates, competent-person reports, and defect-management procedures.

Efficiency should come from improved planning, reliable equipment, competent personnel, and better communication. It should never come from:

• Removing required inspections
• Reducing necessary supervision
• Exceeding rated capacity
• Ignoring load-chart limitations
• Bypassing safety devices
• Rushing the lifting team
• Continuing after conditions become unsafe

Crane preventive maintenance, accurate planning, and lifting-equipment best practices can reduce breakdowns and help prevent avoidable delays.

What Should Happen After an Unsafe Event?

Following an incident, near miss, unexpected load movement, equipment defect, or other unsafe event:

1. Stop the operation.
2. Secure the area.
3. Lower or stabilise the load where it is safe to do so.
4. Isolate defective equipment.
5. Prevent unauthorised reuse.
6. Report the incident or near miss.
7. Preserve relevant evidence.
8. Arrange inspection of affected equipment.
9. Review the lift plan and risk assessment.
10. Identify immediate and underlying causes.
11. Implement corrective actions.
12. Communicate relevant lessons to affected workers.

The investigation should focus on facts, causes, and risk controls. Blame should not be assigned before the evidence has been reviewed.
