Hiring a crane in London involves considerably more than selecting a machine and agreeing a daily rate. The regulatory framework governing lifting operations, the complexity of London's urban environment and the potential consequences of getting a lift wrong mean that the process requires careful planning at every stage. This guide walks through the key steps from initial lift assessment to the day of the lift, giving construction professionals, project managers and facilities managers a practical framework for commissioning crane hire safely and compliantly.
Step 1: Assess the Lift Requirements
Before contacting a crane hire company, spend time assessing exactly what the lift involves. The more clearly you can define the requirements, the more accurate the quotation you receive will be, and the less likely you are to discover during the planning process that the crane originally selected is not right for the job.
Define the Load
Start with the load. What is being lifted? What does it weigh, including lifting accessories? What are its dimensions? Does it have any particular handling requirements, such as fragility, centre of gravity concerns or items that must remain upright throughout the lift? A transformer, for example, must typically be kept within a few degrees of level throughout the move to prevent internal damage to the windings.
Load weight must be confirmed from the manufacturer's documentation or from a direct measurement using a calibrated load cell. Never estimate load weights from visual inspection. A common cause of lifting incidents is an underestimated load weight that takes the crane beyond its rated capacity at the working radius.
Define the Lift Geometry
Lift geometry means the distance and height the load must travel. The pick position is where the crane hooks on. The set position is where the load is placed down. The lift height is the maximum hook height required at any point during the lift, and the lift radius is the maximum horizontal distance from the crane's slew centre to the load's centre of gravity during the lift.
Radius is the most critical variable. As radius increases, crane capacity falls significantly. A crane rated at 100 tonnes at 3 metres radius may only lift 8 to 12 tonnes at 20 metres radius. The relationship between radius and capacity is not linear and varies significantly between crane types and models. Checking the rated capacity chart for the specific crane at the actual working radius is a non-negotiable step in crane selection.
Step 2: Choose the Right Crane Type
With the load and lift geometry defined, the next step is selecting the appropriate crane type. The main options for most London lifting operations are mobile cranes (all-terrain, city cranes or crawler cranes), tower cranes for long-duration fixed-position requirements, and mini cranes for tight-access applications.
Mobile cranes suit most single-day or short-duration lifts where the crane needs to travel to site, set up and complete the lift in a defined time window. Tower cranes suit multi-month construction programmes where a fixed lifting position provides operational efficiency. Mini cranes suit applications where access prevents the use of any larger machine.
If you are uncertain which crane type is right for your job, a free site survey from a qualified lifting engineer is the most reliable way to get the answer. Do not rely on a phone discussion alone for complex or unusual lifts; the surveying engineer needs to see the site, the access routes and the lift position to give authoritative advice.
Step 3: Check Site Access
London site access is almost always more complicated than it first appears. Key questions to work through before confirming a crane booking include the following.
Can the crane carrier reach the site by road? Larger mobile cranes on multi-axle carriers require route survey to confirm clearances under bridges, overhead utilities and through tight junctions. Our logistics team carries out route surveys as part of the booking process for larger machines.
Is there sufficient space on site for the crane to set up and work? Mobile cranes require the outrigger beams to be fully extended and level before the hook load can be applied. The outrigger spread on large all-terrain cranes can be 12 metres by 12 metres or wider. If the crane is working within a few metres of an adjacent building or structure, the outrigger positions must be included in the lifting plan.
Are road closures required? Crane setup positions that encroach on the public highway require a road space booking from TfL or the relevant London borough. In Central London, applications for road space must be made to TfL's Permit Scheme team. Lead times for road space bookings range from 5 working days for minor restrictions to several weeks for major closures in busy areas. Start this process early.
Step 4: Understand LOLER Requirements
The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) apply to all lifting operations carried out by or for duty holders in the workplace. LOLER has three core requirements for lifting operations that every client commissioning crane hire must understand.
First, every lifting operation must be properly planned by a competent person. This means a formal lifting plan produced by someone with appropriate training and experience in lifting operations. A site manager who has seen crane operations but has no formal lifting training does not meet the competent person standard.
Second, the operation must be appropriately supervised. For most crane operations, this means a qualified slinger/signaller responsible for rigging the load and communicating with the operator, and an appointed person overseeing the operation.
Third, the operation must be carried out in a safe manner. This is self-evidently the objective of all the prior planning, but it also means that if conditions on the day do not match the approved lifting plan, the lift must be paused until the plan is updated to reflect the changed conditions.
Step 5: The Method Statement
The method statement describes the sequence of operations, the people involved, their roles and responsibilities, and the controls in place to manage the identified risks. It works alongside the lifting plan, which contains the technical detail, to provide a comprehensive picture of how the operation will be carried out.
The method statement must be reviewed and approved by the principal contractor's site management team before work begins. On most London construction sites, this review takes place as part of the pre-start meeting, at which the crane company, the appointed person and the principal contractor's representative agree the operation and confirm that site conditions match the plan.
Step 6: The Appointed Person
The appointed person is the individual who takes statutory responsibility for planning the lifting operation under LOLER 1998. They must be competent, which in practice means holding LEEA appointed person certification or equivalent formal training backed by practical experience of the operation type.
On a contract lift, the crane hire company provides the appointed person. On a crane-with-operator hire, the client provides their own appointed person. If you do not have a trained appointed person available for the lift, a contract lift arrangement is the correct approach. Attempting to carry out a crane operation without a competent appointed person is a breach of LOLER and a significant safety risk.
Step 7: Book the Crane and Confirm the Plan
Once all the above steps have been worked through, confirm the crane booking with a written purchase order or hire agreement. Confirm the crane specification, the dates, the operator category, the hire rate and all additional costs. Ensure you have received, reviewed and approved the lifting plan and method statement before the crane arrives on site.
Carry out a pre-lift briefing on the morning of the lift with all personnel involved in the operation. Confirm that site conditions match the approved plan. If they do not, stop and update the plan before proceeding.
