Crane Inspections in London | EIS

Local Service Hub

Cranes are among the most safety-critical items of lifting equipment found on construction sites, in ports, and across heavy industry. The forces involved in crane operations mean that any undetected defect can have catastrophic consequences. Thorough examinations verify that every structural, mechanical, and safety system is functioning within safe parameters.

Our local network of qualified Engineer Surveyors provides independent crane inspections across London. Operating in London presents unique logistical considerations including congestion charge zones, restricted delivery hours, and limited site access. Our Engineer Surveyors are experienced in navigating these constraints and can schedule inspections during early mornings, evenings, or weekends to minimise disruption to building occupants.

Crane Inspections Across London

London's economy is the largest of any city in the UK and one of the largest in Europe. The city's built environment is in a constant state of renewal, with major construction projects, infrastructure upgrades, and building refurbishment programmes generating continuous demand for lifting equipment across every borough. The density of commercial, residential, and public sector buildings also creates sustained demand for lift and access equipment maintenance.

London's inspection demand spans virtually every service category. High-rise construction drives crane and access equipment needs. The city's vast stock of commercial and residential buildings sustains continuous demand for passenger lift examinations. Logistics operations across outer London boroughs require mobile plant and general lifting equipment inspections. Hospital trusts, local authorities, and educational institutions represent a significant public sector client base.

Equipment We Inspect

Tower cranes
Mobile cranes
Crawler cranes
Overhead travelling cranes
Gantry cranes
Jib cranes (wall-mounted and free-standing)
Loader cranes (lorry-mounted)
Mini cranes and spider cranes

Crane thorough examinations assess structural integrity of the boom, jib, and mast sections. Wire rope condition is checked for broken strands, corrosion, and distortion. Hook blocks, safety catches, and load indicators are tested. Slew rings, bearings, and outrigger systems are inspected for wear. Limit switches, overload protection, and emergency stop systems are verified as operational.

Legal Requirements and Inspection Frequency

Under LOLER Regulation 9, cranes must be thoroughly examined at least every 12 months. Cranes used for lifting persons must be examined every 6 months. After installation, erection, or any assembly that could affect safety, a crane must be thoroughly examined before being put into service. The competent person must also assess the adequacy of the crane's installation including ground conditions and proximity hazards.

Required Inspection Interval

Every 12 months (every 6 months if used for lifting persons); also after each erection or assembly

Common Defects Identified

During crane inspections across London, our Engineer Surveyors regularly identify:

Wire rope deterioration — broken strands, birdcaging, or corrosion
Hydraulic hose wear, chafing, and oil leaks
Structural cracking at boom weld joints
Limit switch or anti-two-block device malfunction
Outrigger pad cracking or deformation
Slew ring bearing wear beyond tolerance

Infrastructure and Major Projects

London's infrastructure drives significant demand for crane inspections. Key sites and projects include:

Crossrail / Elizabeth Line
Thames Tideway Tunnel
Bank Station capacity upgrade
Old Oak Common and HS2 terminus
Battersea Power Station development
Nine Elms regeneration, Vauxhall

Frequently Asked Questions

How often do cranes need a thorough examination?

Cranes require thorough examination at least every 12 months under LOLER. If the crane is used to lift people, the interval reduces to 6 months. A thorough examination is also required after every installation, erection, or assembly at a new location.

Can a crane be used if the examination certificate has expired?

No. Operating a crane beyond its thorough examination due date is a breach of LOLER and a criminal offence. The crane must be taken out of service immediately until a valid report of thorough examination has been issued by a competent person.

Who is responsible for arranging crane inspections?

The duty holder — typically the employer or the person who controls the use of the crane — is legally responsible for ensuring thorough examinations are carried out on time. This responsibility cannot be delegated to the crane operator.

Can you work around London's access restrictions and congestion charges?

Yes. Our London-based Engineer Surveyors are experienced with congestion charge zones, ULEZ requirements, restricted delivery hours, and limited site access. We routinely schedule inspections during early mornings, evenings, or weekends to minimise disruption to building occupants and avoid peak traffic.
