Planning a safe lifting operation for heavy equipment
A safe lift of heavy plant, machinery or steelwork is rarely the result of a single decision on the day. Across Australian worksites in mining, construction, ports and renewable energy, lifting operations are planned days or weeks in advance, documented and signed off before a single sling is attached. From a transformer replacement near Perth to a turbine component change in the Pilbara, the same disciplined approach applies: identify the load, understand the environment, choose the right equipment and people, then control the work step by step. When that chain breaks, even a simple pick can turn into a serious incident.
Australian safety law treats lifting as high-risk work. Under the model Work Health and Safety Act 2011 and the WHS Regulations, crane operation, dogging and rigging require a licence issued by the relevant state regulator, such as SafeWork NSW, WorkSafe Victoria or Workplace Health and Safety Queensland. Codes of practice from Safe Work Australia provide practical guidance on planning, supervision and competency. For businesses and supervisors, planning a safe lifting operation for heavy equipment is therefore as much about compliance and documentation as it is about steel, wire rope and hydraulics.
Reading the site, the load and the law
Before any lift study begins, the planner must build a clear picture of the site, the load and the legal framework. In Australia, that picture is shaped by three layers: the WHS laws in each state or territory, Australian Standards such as AS 1418 and AS 2550 for cranes, and the procedures of the principal contractor or asset owner. On a wind farm site in western Victoria, for example, the lift planner may also need to satisfy the network operator's safe system of work and an OEM's manual handling guidance.
The environment itself is often more challenging than the load. Heat, dust, uneven terrain and remote access shape what is feasible. Lifting near live overhead power lines in a Melbourne rail corridor demands minimum approach distances and often a power outage agreement with the asset owner. Coastal wind farms near Warrnambool routinely deal with gusts above 50 km/h, which can shut down a crane entirely. Ground bearing pressure must be checked for outrigger pads or crawler tracks, particularly on backfilled ground common in urban redevelopment projects in Sydney or Brisbane.
A solid site assessment also captures hidden constraints: underground services, adjacent traffic, overhead services, and the proximity of other cranes or mobile plant. Many Australian projects now use 3D lift planning software to model the lift envelope and slewing path against a laser-scanned point cloud of the site. This visualises clashes that a paper-based plan might miss, such as a boom passing too close to scaffolding on a busy inner-city arterial.
Building the risk picture and the lift plan
Once the site is understood, the planner turns to the load and the activity. The goal of risk assessment is not to produce paperwork but to make sure every credible hazard has been controlled before work starts. Safe Work Australia defines a hierarchy of controls: eliminate, substitute, isolate, engineer, administrate and use PPE. For most heavy lifts, elimination is rarely possible, but substitution might mean prefabricating a module at ground level, splitting an oversized component, or changing the crane configuration.
The deliverable is usually a documented lift plan or, for complex operations, a lift study. It sets out the scope of work, the load weight and centre of gravity, the rigging arrangement, the crane configuration, the slewing path, ground preparation, sequence of events, and controls for each identified hazard. On a Brisbane high-rise project lifting a 12-tonne air-handling unit to a plant room, the study may run to dozens of pages, including structural assessments of the slab and a detailed rescue plan.
Key elements that should always appear in a lift plan include:
- A clear description of the load, its mass, dimensions and centre of gravity
- The crane type, capacity chart and configuration for the planned radius
- Rigging gear specifications, including slings, shackles and lifting beams
- The exclusion zone, communication method and emergency response plan
Choosing the crane, the gear and the people
Selecting the right crane is one of the most consequential decisions in any lifting operation. Mobile cranes range from small all-terrains suitable for a workshop service lift in Hobart, to 750-tonne crawlers used to erect tunnel boring machine components in Sydney harbourside infrastructure. The choice is driven by the load, the radius, the lift height, the ground conditions and access constraints. Capacity charts are read carefully, with deductions applied for blocks, hooks, slings and any below-the-hook lifting device such as a vacuum lifter or hydraulic grab.
Rigging gear is selected to match both the load and the crane. Synthetic round slings are widely used because they are light and flexible, but for abrasive or high-temperature environments, wire rope or chain slings may be safer. Lifting beams and spreader bars control sling angles and reduce compression forces on the load. Every item must be tagged, in date for periodic inspection, and rated for the job; gear without a current inspection record should not enter service.
Personnel are the third pillar. Dogging, rigging and crane operation are licensed classes of high-risk work in Australia, with specific categories and capacity limits. A dogger with a CH licence class can sling and direct loads, while a crane operator with a CO licence has endorsements for different crane types. On a heavy lift site you would expect a lift supervisor, a dogger, a rigger, a crane operator and the personnel attaching and detaching the load, all briefed and signed on to the plan.
Controlling the lift on the day
Even an excellent plan fails if it is not implemented with discipline. The pre-lift checklist is the last gate before the hook goes up. Typical items include verifying the load weight against the crane chart, checking weather and wind speed, confirming outrigger extension and pad size, inspecting slings and shackles, and ensuring the communication method is tested. On remote sites, such as a haul truck tyre change in the Pilbara, supervisors also confirm access roads, lighting and fatigue management plans, particularly during night shifts when heat and isolation dull concentration.
During the lift, the operator and dogger maintain continuous radio communication on a single dedicated channel. The exclusion zone is enforced with barricades, signage and trained spotters. If the load begins to swing or wind picks up beyond the plan's limit, the lift is stopped. If ground conditions deteriorate, for example after sudden rain turns a hardstand into mud, outrigger packing is rechecked before the next pick. A documented stop-work authority means anyone in the team can pause operations without fear of reprisal, a hallmark of mature safety culture on Australian heavy industry sites.
Post-lift, the area is secured, gear is inspected for damage, and any near-hits are recorded. Lifting gear that has been shock-loaded or shows surface damage is tagged out. These small disciplines keep the next lift as safe as the last one, and they help prevent the most common causes of lifting incidents on Australian sites: inadequate planning when conditions change, exceeding the crane's capacity chart at the working radius, using damaged or expired rigging gear, and poor communication between operator, dogger and ground crew.
Learning from each lift and getting better
A safe lifting operation does not end when the load is landed. The lift debrief captures what went well, what could be improved, and whether assumptions matched reality. Many Australian principal contractors feed these lessons into a central lifting library, so a lift study completed for a substation in Adelaide can be adapted for a similar substation in Perth, saving planning time and embedding proven controls.
Compliance evidence is also reviewed. Sign-on sheets, crane dockets, pre-start checklists, inspection records and photographs are filed against the lift permit or SWMS. For organisations working under ISO 45001, this evidence is essential during external audits. Internal audits frequently identify gaps such as outdated load charts, expired rigging gear or training records that have drifted out of date.
For workers and supervisors who want to formalise their skills, structured training in lift planning, dogging, rigging and crane operations is available through registered training organisations across Australia. Short courses covering lift director duties, advanced rigging and crane appreciation are particularly valuable for site engineers and supervisors who coordinate lifts but do not hold a high-risk work licence themselves. Investing in this training is often the single biggest improvement a business can make to the safety and reliability of its lifting operations.
| Crane type | Typical applications | Key advantages | Key limitations |
|---|---|---|---|
| Mobile all-terrain | General construction, plant maintenance, infrastructure | Roadable, fast rig-up, versatile capacity | Limited by ground pressure and outrigger spread |
| Crawler crane | Wind farms, major infrastructure, modular construction | Excellent stability, high capacity, handles uneven ground | Heavy transport loads, long rig-down time |
| Rough terrain crane | Mining, remote energy projects, unpaved sites | Compact, four-wheel steering, strong off-road | Lower lift heights and radii than all-terrains |
| Tower crane | High-rise construction, dense urban sites | High hook height, small footprint, electric efficiency | Fixed location, sensitive to wind, complex dismantle |
Practical signs that a lift plan is well prepared and the team is competent:
- The plan clearly identifies the load, crane configuration and exclusion zone
- All personnel hold current high-risk work licences for their role
- Pre-lift checks are completed and signed before every shift
- A documented stop-work authority is understood by everyone on site
