A HIAB arriving on site can look like the simple part of a delivery. In practice, HIAB lift preparation determines whether materials are placed safely and efficiently or whether the job is delayed by restricted access, unstable ground or an unclear lifting plan. The right preparation protects people, keeps the programme moving and makes sure the lorry, load and lifting area are suitable before equipment is dispatched.
For site managers and contractors, this starts well before the delivery date. A clear conversation about the load, the location and the site conditions gives the lifting provider the information needed to recommend the right vehicle, crane capacity and operating arrangement.
Start with the lift, not the vehicle
A HIAB is often requested because materials need to be delivered and placed in one visit. That might mean steelwork, timber packs, generators, containers, glazing, plant or landscaping materials. However, the load weight alone does not determine the correct solution.
The lifting radius matters just as much. A crane may be able to lift a stated weight close to the lorry, but its available capacity reduces as the boom reaches further out. If the load has to clear a fence, reach over excavations or be positioned at the rear of a constrained site, the required radius can change the vehicle specification completely.
Provide accurate details of the item being lifted, including its weight, dimensions and lifting points. If the load is bundled, packaged or supplied on stillages, confirm how it is secured and whether it can be slung safely. The centre of gravity is particularly relevant for irregular loads, machinery and long sections of material. Assumptions made at the booking stage can become a problem once the crane is set up.
Where the exact weight is unknown, obtain it from the supplier or manufacturer rather than estimating. An honest discussion early on is far more useful than finding that a planned lift cannot proceed safely on the day.
HIAB lift preparation begins with a site review
The lifting area should be assessed with the same care as the load. A site visit is not required for every straightforward delivery, but photographs, videos, dimensions and a detailed briefing can be enough for an experienced lifting team to identify likely constraints. More complex or higher-risk work may require a formal survey and lift plan.
Access is the first consideration. The delivery vehicle needs a route that accommodates its length, width, height and turning circle. Check gates, narrow lanes, parked vehicles, low bridges, weight restrictions and sharp turns. It is also worth confirming whether the driver can leave the site without reversing over a long distance or relying on unsuitable ground.
Once in position, the lorry needs room to deploy its stabiliser legs. This working footprint is wider than many people expect. Hoarding, stored materials, welfare units, skips and temporary barriers can prevent the crane from setting up correctly even when the vehicle itself can get through the gate.
Ground conditions need close attention. Stabiliser legs place concentrated loads onto the surface, so the ground must be firm, level and capable of supporting the vehicle and outrigger forces. Freshly made-up ground, block paving, cellars, drainage runs, service ducts, manhole covers and basement slabs all need consideration. Appropriate spreader pads or mats may be needed, but they do not turn unsuitable ground into a safe lifting base.
If there is any uncertainty, raise it before the lift. The site team may need to provide information about underground services, structural loading limits or recently excavated areas. This is especially relevant on redevelopment schemes and confined urban sites across London and the South East.
Look above as well as below
Overhead hazards can restrict where a HIAB can operate and how the boom can travel. Electricity lines, telecommunications cables, trees, scaffolds, building projections and adjacent structures should be identified in advance. Overhead power lines require particular care, with safe clearances and controls agreed before work starts.
The route the load will take also matters. A clear landing area is needed, not simply a space where the load can be lowered. Materials should not be placed where they obstruct emergency routes, create a trip hazard, overload a structure or prevent other trades from working safely.
Define responsibilities before the delivery date
A successful lift depends on clear communication between the site and the lifting provider. The person arranging the hire should establish who is responsible for the lift planning, site preparation, traffic management and receiving the load. On some jobs, the HIAB provider supplies an operator and manages the crane operation, while the customer retains responsibility for the site, access and the area where the lift takes place. The precise arrangement depends on the scope of hire and should never be assumed.
A competent person on site should be available to meet the vehicle, confirm the agreed position and deal with changing conditions. They should understand where the load is going, whether the route is clear and who needs to be kept out of the lifting area.
The banksman or slinger-signaller role should also be agreed. Effective communication is essential when the operator cannot see the landing position clearly. The appointed person must be competent for the task and use recognised signals or agreed radio communication. Multiple people giving instructions creates confusion and should be avoided.
For planned lifting operations, the level of documentation should be proportionate to the complexity and risk. A routine, straightforward lift may require a simpler arrangement than a lift near live services, public areas, busy roads or occupied premises. The key point is that the method has been considered, responsibilities are understood and the operation is properly controlled.
Keep people and traffic away from the lift zone
The lifting area needs an exclusion zone that prevents people from walking beneath a suspended load or into the crane’s operating area. On a busy site, this may mean coordinating delivery times with other trades, pausing vehicle movements or using barriers and a dedicated marshal.
Public-facing locations need additional planning. Footpaths, roads, cycle lanes and neighbouring entrances may need to be managed so that pedestrians and vehicles are not exposed to the lifting operation. If a road closure, parking suspension or highway permit is needed, allow enough time to arrange it. A last-minute booking can turn a simple delivery into a costly delay.
Consider the full movement of the vehicle too. Reversing, turning and departing must be managed safely, particularly where site entrances open directly onto public roads. A clear delivery slot gives the team time to set up without pressure from waiting traffic or other contractors.
Confirm the load is ready to lift
Before the HIAB arrives, check that the load is available, accessible and prepared for the agreed lifting method. Materials buried behind other deliveries, still being loaded by a supplier or secured with unsuitable packaging can hold up the entire operation.
Any lifting accessories must be appropriate, identifiable and in suitable condition. The operator should inspect equipment before use, but the site should not expect an improvised arrangement to solve a load that has no suitable lifting points. If a bespoke frame, chains, lifting beam or other accessory is required, it should be discussed during planning.
Weather can also affect the job. High winds can make handling large panels, cladding, timber sheets or awkward loads unsafe. Heavy rain may change ground conditions, while poor visibility can affect communication and vehicle movements. A practical contingency plan allows the lift to be delayed or rearranged where conditions are no longer acceptable.
On the day, allow time to reassess
Even a well-planned lift needs a final check on arrival. The operator should be given time to inspect the access route, set-up area, load and surrounding hazards. Conditions may have changed since the original briefing: another contractor may have placed materials in the working area, rain may have softened the ground, or a new scaffold may have reduced boom clearance.
Do not pressure the lifting team to proceed because a delivery slot is tight. Stopping to resolve an issue is the right decision when the agreed plan no longer reflects site conditions. The most efficient lift is one that is properly prepared, carried out once and completed without damage, incident or avoidable waiting time.
For projects across the South of England, JBL Group’s friendly, experienced team can provide honest guidance on the right HIAB arrangement, certified operatives and the practical details that need to be agreed before delivery. Sharing site information early gives everyone the best chance of a safe, on-time lift.
Good preparation is not paperwork for its own sake. It is the practical work that allows the right vehicle to arrive, set up with confidence and place the load where it is needed.
