Crane Inspections in Kent
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.
Crane Operations Across Kent
Crane work in Kent spans construction, ports, manufacturing, and infrastructure projects. Each environment puts different demands on the crane and on the statutory examination regime that keeps it in service.
Crane activity in Kent is concentrated around two major drivers: the Thames Gateway regeneration programme in the north, and port and infrastructure operations across the county. Tower cranes and mobile cranes support large-scale construction at Ebbsfleet, Dartford, and the Medway towns, while overhead and gantry cranes operate in Kent's engineering workshops and port facilities. Tower cranes and other cranes whose safety depends on how they are installed must be thoroughly examined after each erection and before use, and cranes generally at least every 12 months (every 6 where they lift people), unless an examination scheme sets different intervals.
Key Sectors Driving Crane Inspections Demand in Kent
- Construction and civil engineering (Thames Gateway, HS1 corridor)
- Port operations (Dover, Sheerness, Thamesport)
- Heavy engineering and fabrication (Medway)
- Infrastructure and utilities
- Steel erection and structural work
Crane Categories Across Kent
- Tower cranes on major construction sites
- Mobile cranes (all-terrain and rough terrain)
- Overhead travelling cranes in workshops
- Loader cranes (lorry-mounted hiab type)
- Gantry cranes at port and industrial facilities
- 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.

BS 7121 Considerations for Kent Operations
BS 7121 is the non-statutory code of practice for safe use of cranes: it doesn't create legal duties of its own, but HSE's guidance on LOLER (L113) points to the BS 7121 series for recommendations on the safe use of cranes, including the planning of lifting operations. Our reports note conditions that affect either the LOLER thorough examination conclusion or the BS 7121 picture, so duty holders in Kent can present a coherent compliance record.
Legal Requirements and Inspection Frequency
Under LOLER Regulation 9, cranes must be thoroughly examined at least every 12 months, or at least every 6 months if used for lifting persons, unless an examination scheme sets different intervals. Where a crane's safety depends on its installation conditions, such as a tower crane, it must be thoroughly examined after installation, and after assembly at a new site or in a new location, before it is 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
At least every 12 months (every 6 months if used for lifting persons), or as an examination scheme sets; also after installation or assembly at a new site where the crane's safety depends on its installation
Scheduling Note for Kent
Crane thorough examinations in Kent often need to be coordinated around construction programme schedules, port vessel timetables, and site access restrictions. Our engineers hold the necessary site induction certifications for major Kent construction sites and port facilities.
Common Defects Identified
During crane inspections across Kent, 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
Kent's infrastructure drives significant demand for crane inspections. Key sites and projects include:
- Port of Dover
- Channel Tunnel / Eurotunnel terminal, Folkestone
- M20 and M2 motorway corridors
- Thames Gateway regeneration zone
- High Speed 1 (HS1) rail link
- Medway ports at Sheerness and Thamesport
LOLER & PUWER Compliance Guides
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. An examination scheme drawn up by a competent person can set different intervals. Where a crane's safety depends on how it is installed, such as a tower crane, a thorough examination is also required after installation and after assembly at a new site or location, before it is used.
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.
Do you cover all of Kent including rural areas?
Yes. Our Engineer Surveyors are based across Kent and cover the entire county from the Thames Estuary towns in the north through to the Romney Marsh in the south. We regularly attend sites in rural locations, farms, and small workshops as well as major industrial estates and construction sites.
