Overhead Travelling Crane Thorough Examinations

Overhead Travelling Cranes Within Industry

Overhead travelling cranes are fixed lifting systems designed to move heavy loads horizontally and vertically within a defined working area. They consist of a bridge that travels along elevated runway beams, with a hoist and trolley that move across the bridge. This design allows loads to be lifted, lowered, and transported across large spaces with precision and control, making overhead travelling cranes ideal for repetitive and heavy lifting tasks.

These cranes are commonly installed in factories, workshops, warehouses, and large industrial buildings where floor space needs to remain clear. They can be operated by pendant controls, remote controls, or from a crane cabin, depending on the size and application. Overhead travelling cranes are capable of lifting extremely heavy loads, often ranging from several tonnes to hundreds of tonnes, and can be fitted with various lifting attachments to suit different materials and processes.

Overhead travelling cranes are widely used across many industries. In manufacturing and engineering, they are essential for moving machinery, components, and raw materials. The steel and metal processing industries rely on them for handling coils, billets, and fabricated sections. They are also commonly used in automotive plants, shipbuilding, power generation, waste processing, and heavy fabrication environments.

By providing efficient, safe, and precise lifting within a controlled area, overhead travelling cranes play a vital role in industrial operations. Their ability to handle heavy loads repeatedly while reducing manual handling and floor-level congestion makes them a key piece of equipment in many large-scale and heavy-duty industries.

What’s covered during your SEIS Thorough Examination.

A LOLER (Lifting Operations and Lifting Equipment Regulations 1998)thorough examination of an overhead travelling crane (OTC) is a legally required inspection carried out  by a competent person to ensure the crane is safe for continued use. Below is a detailed breakdown of what is typically covered:

 General Examination

Verification that the crane complies with its manufacturer’s specifications and current legislation.
Check of all relevant documentation, such as:

  • CE/UKCA conformity documents
  • Maintenance records
  • Load test certificates
  • Previous thorough examination reports
  •  Confirmation that all safety markings (SWL, ID plates) are legible and accurate.

 Structural Integrity

  • Bridge beams and runway rails checked for cracks, corrosion, deformation, or damage.
  • End carriages and connection points inspected for alignment, wear, and secure bolting.
  •  Examination of welds and joints for signs of fatigue or failure.
  • Stops and buffers at travel limits checked for security and condition.

 Mechanical Components

  • Condition of throat opening, latch operation, deformation, and wear.
  • Check for cracks or excessive corrosion.

Wire ropes or chains:

  • Inspection for broken wires, kinks, crushing, wear, corrosion, or stretching.
  • Correct reeving and tension.

Pulleys and sheaves:

  •  Smooth rotation, no sharp edges, and correct alignment.

Gearboxes and bearings:

  • Checked for leaks, abnormal noise, or excessive play.

Electrical Systems

  • Inspection of control panels, limit switches, emergency stops, and isolation devices
  • Check all wiring, insulation, and connectors for damage or overheating.
  • Verify operation of travel, hoist, and cross-travel controls.

 Safety and Control Systems

  • Limit switches for upper and lower hoist travel, trolley, and bridge travel.
  • Overload protection devices (if fitted) and brake systems tested for proper function
  • Emergency stop circuits tested.
  • Anti-collision systems(if fitted) checked for correct operation.

 Supporting Infrastructure

  • Runway beams and brackets inspected for wear, alignment, and fixings.
  • End stops and buffers verified for proper condition and secure attachment.
  • Check rail alignment and condition (no excessive wear or looseness).

 Functional Testing

Operate the crane under no-load and test-load conditions to verify:

  • Smooth operation of all motions (hoist, cross-travel, long-travel).
  •  Effectiveness of brakes and limiters.
  • Stability and balance during lifting and movement.

 Documentation and Reporting

After the inspection, the competent person will issue a LOLER Thorough Examination Report. This must include:

  • Date of the examination
  • Details of the equipment inspected
  • Findings, including any defects
  • Recommendations or required actions
  •  Date of next examination due
  • Statement on whether the equipment is safe to continue using

If any serious defects are found that pose immediate danger, they must be reported to the duty holder and the enforcing authority (e.g., HSE) immediately.

Summary

An overhead travelling crane LOLER inspection ensures that the lifting elements of the machine are safe, compliant, and fit for use. It helps prevent accidents caused by worn load rope(s), damaged components, or malfunctioning lifting mechanisms. While it does not replace regular maintenance, PUWER and LOLER inspections are a crucial legal requirement for keeping lifting operations safe and avoiding costly breakdowns or incidents.

Overhead Travelling Crane FAQ's

Yes. Under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER 1998), overhead travelling cranes must undergo a statutory Thorough Examination at defined intervals to ensure they are safe for lifting operations.

LOLER requires a Thorough Examination:

  • Every 12 months for cranes lifting goods

  • Every 6 months if used for lifting people

  • After exceptional circumstances such as overload, collision, or major repair

  • At intervals specified in a Written Scheme of Examination

Routine operator checks and maintenance do not replace the legal requirement for a Thorough Examination.

A Thorough Examination typically includes inspection of:

  • Bridge structure and runway beams

  • End carriages and wheel assemblies

  • Hoist unit and trolley system

  • Wire ropes or chains

  • Hooks and lifting attachments

  • Braking systems

  • Electrical systems and control panels

  • Limit switches and overload protection devices

  • Safe Working Load (SWL) markings

The competent person assesses whether the crane is safe to continue lifting operations.

Yes. Bridge cranes, gantry cranes, straddle carriers, and overhead travelling cranes are all classed as lifting equipment under the Lifting Operations and Lifting Equipment Regulations 1998 and require periodic Thorough Examination.

No. Servicing ensures the crane is maintained and mechanically sound. A LOLER Thorough Examination is a legal safety inspection required under UK law and focuses on identifying defects that could lead to danger during lifting operations.

Yes. Hooks, slings, chains, shackles, and other lifting accessories connected to the crane are classed as lifting tackle and must be inspected separately — typically at 6-month intervals under LOLER.

Load testing is not required at every Thorough Examination but may be necessary:

  • After major structural repair

  • After installation or relocation

  • If required in a Written Scheme of Examination

The competent person determines whether load testing is required.

The inspection must be performed by a competent person with appropriate knowledge, training, and experience in crane systems and lifting equipment safety. Independent inspection providers are commonly used to ensure impartial compliance.

Why Overhead Travelling Crane Thorough Examinations Matter For You & Your Business. 

Why LOLER98 Thorough Examinations Matter

LOLER98 thorough examinations are a legal requirement in the UK for all lifting equipment used at work, and for good reason. These inspections ensure that lifting equipment, such as cranes, hoists, slings, and lifting accessories are safe to use, and fit for purpose. The nature of lifting operations means that equipment failure can lead to catastrophic consequences, including serious injury, fatalities, and significant damage to property. By carrying out regular, scheduled thorough examinations by a competent person, businesses can identify wear and tear, structural damage, or faulty mechanisms before they result in an incident.

Pros of Getting a Thorough Examination in line with LOLER98

Legal Compliance and Risk Reduction: The most obvious advantage is staying compliant with health and safety law. Compliance avoids potential legal action, fines, or even prosecution. More importantly, it drastically reduces the risk of workplace accidents caused by lifting equipment failure.

Improved Safety Culture: Regular inspections foster a proactive safety culture within the organisation. Employees are more likely to trust equipment and feel safe in their work environment when they know thorough checks are in place.

 Extended Equipment Lifespan: Regularly maintained and inspected equipment typically lasts longer. Examinations can identify early signs of damage or fatigue, allowing for preventative maintenance that avoids costly replacements or repairs.

 Insurance and Liability Protection: Insurers may require evidence of LOLER compliance in the event of an incident. Without valid inspection records, insurance claims could be denied or reduced, leaving the business liable for damages.

 Operational Efficiency: Detecting potential issues before they lead to equipment failure helps prevent unscheduled downtime. This keeps operations running smoothly and avoids the knock-on effects of delayed projects or interrupted workflows.

Cons of Failing to Carry Out LOLER Thorough Examinations

 Legal and Financial Consequences: Failing to comply with LOLER can result in enforcement action from the Health and Safety Executive (HSE), including improvement notices, prohibition notices, fines, or even prosecution. Legal battles and associated costs can be financially crippling.

 Increased Risk of Accidents: Equipment that hasn’t been thoroughly examined is far more likely to fail. Such failures can lead to injuries or fatalities, particularly in high-risk environments like construction or manufacturing. Beyond the human cost, the reputational damage to a business can be severe and long-lasting.

 Higher Repair and Replacement Costs: Neglecting inspections can allow minor issues to develop into major faults. These may require costly emergency repairs or complete equipment replacement, expenses that could have been avoided through routine examinations.

 Loss of Business and Clients: Clients often expect their contractors or suppliers to uphold strict safety standards. A failure to meet legal obligations like LOLER can result in lost contracts or blacklisting from future work, especially in regulated industries.

 Increased Insurance Premiums or Invalidated Coverage: As mentioned, insurers may increase premiums or deny coverage entirely if a business can't provide evidence of up-to-date LOLER compliance, placing a heavier financial burden on operations.

LOLER thorough examinations aren’t just a box-ticking exercise - they are an essential component of a responsible, safety-first approach to using lifting equipment. The benefits of compliance are wide-ranging, from protecting human life to reducing costs and maintaining operational integrity. Conversely, the risks of neglecting these inspections can be devastating on multiple levels.
