- Rigging is the process of arranging and installing heavy equipment for lifting and moving, whereas dogging refers to the process of slinging and fastening weights in preparation for lifting.
- To ensure the weight is lifted safely, the dogger must select and attach the appropriate lifting gear, check that the load is balanced, and communicate with the crane operators.
- Riggers are the individuals accountable for the planning and preparation of rigging equipment, as well as the inspection of such equipment, the attachment of said equipment to the load, and the coordination of said attachment with crane operators to ensure safe lifting.
- Rigging and dogging techniques require specialised training and certification to ensure that items are lifted and moved safely and effectively.
What Is The Difference Between Rigging And Dogging?Some of the key distinctions between rigging and dogging are summarised in the table below
The action of setting up and installing large pieces of machinery and equipment before being lifted and relocated.
The procedure of slinging and fastening loads to be lifted and moved by cranes or hoists.
Includes planning, preparation, and execution of the complete process of relocating equipment or machinery.
Dedicated to the mechanics of carrying and relocating weight.
Generally performed by skilled and experienced riggers with thorough training in rigging equipment and techniques.
Often carried out by doggers who have certification in slinging and fastening loads.
Incorporates the utilisation of cables, chains, slings, hoists, and other rigging equipment.
Slings, hooks, chain blocks, shackles, lever hoists, slings, and other lifting gear are used to secure and transport loads.
Includes handling large, potentially dangerous pieces of machinery and equipment.
Involves handling heavy objects that, if not securely fastened, could cause injury or property damage.
A rigging licence or certificate of competency can only be obtained after extensive training and testing.
A high-risk work licence or a dogging certification are two examples of the training and certification necessary for dogging.
What Does A Dogger Do?
A dogger is an employee who slings and secures goods before they are raised and transferred with cranes or hoists. A dogger’s job is to ensure the load is securely fastened to the lifting equipment, evenly distributed, and can’t fall or swing about throughout the raising operation.
A dogger may be responsible for the following tasks:
- Choosing the best slings, chains, or other lifting equipment for the load based on its weight, size, and shape.
- Securing the weight and the lifting equipment by attaching and positioning the slings or other lifting gear.
- Adjusting the placement of the slings or other lifting equipment to achieve load balance.
- Ensuring the cargo is raised and moved securely by communicating with the crane operator or other workers participating in the lifting operation.
- Verifying the lifting equipment is working by conducting pre- and post-use checks.
- Doing the lifting operation following all applicable safety regulations and procedures can help prevent any mishaps.
An important function of a dogger is to ensure that large objects are lifted and moved safely and efficiently, with minimal chance of injury to workers.
What Does A Rigger Do?
A rigger is an employee who instals large machinery and equipment in preparation for lifting and transportation. In particular, a rigger may be responsible for doing the following:
- Reading and understanding engineering drawings, schematics, and specifications to determine the best rigging equipment and techniques for lifting and moving equipment or machinery.
- Organising and setting up the cables, slings, chains, and hoists that will be utilised for the lifting and transporting.
- Checking all of the rigging gear to ensure it’s in perfect working order.
- Attaching the rigging equipment to the lifting and moving equipment or machinery, assuring optimum positioning and security.
- Facilitating the safe and effective lifting and relocation of heavy machinery or equipment by directing and coordinating the activities of the crane operator and other workers participating in the lifting operation.
- Disassembling and uninstalling the rigging equipment and attachments following the completion of the lifting and moving process.

What Role Do Winch Systems and Slinging Techniques Play In The Construction Industry?
Winch systems and slinging techniques are essential for the construction industry because they allow for the safe and efficient lifting and moving of heavy loads. Construction workers can securely attach slings and cables to the load and the lifting equipment by using proper slinging techniques, preventing accidents and damage to the load.
The Winch system provides the power to lift and move loads over short or long distances, reducing physical strain and increasing productivity. They are also useful in difficult terrain and remote areas where other lifting equipment may not be available.
What Is The Significance Of Inspecting Lifting Gear?
When it comes to dogging and rigging, inspecting lifting equipment is crucial to ensuring the following:
- Accident avoidance: Lifting equipment that has been regularly inspected is less likely to malfunction or cause injury during rigging or lifting operations.
- Safety and reliability: Any damage, wear and tear, or defects that could make the equipment less reliable are found when lifting gear is inspected. This makes sure that the equipment can safely carry loads.
- Legal compliance: In many jurisdictions, regular inspections are required by law to ensure compliance with safety regulations and standards.
- Reducing expenses: Lifting equipment inspections can save money by spotting minor issues before they become major and require expensive repairs.
- Reputation: A commitment to safety and compliance can improve the reputation of a business or individual involved in dogging and rigging activities.
What Are The Different Types Crane Loading Platforms
The primary purpose of crane loading platforms is to provide a secure and safe working surface for crane operators and riggers during dogging and rigging operations.
Common crane loading platforms for dogging and rigging include the following:
- Fixed Platform: Fixed crane loading platforms are permanently installed structures and typically used in a specific location or area.
- Portable Platform: Portable crane loading platforms are lightweight and compact, making them ideal for confined spaces.
- Adjustable Crane Loading Platforms: Adjustable crane loading platforms can be raised or lowered to different heights, allowing workers to work at various levels depending on the job requirements.
- Cantilevered Platform: Cantilevered crane loading platforms are made to extend past the support structure, so workers can get to hard-to-reach areas.
- Suspended Platform: Suspended crane loading platforms are commonly employed in high-rise construction and maintenance projects and are suspended from the roof or a crane.
- Bridge Platform: Loading platforms for bridge cranes are used to reach the bottom of bridges and other high structures.
Is White Card Required For Dogging And Rigging Operators In Construction Sites?
The White Card training programme covers essential information about workplace health and safety, hazard identification, risk management strategies, and legal requirements in the construction sector.
A White Card certification is generally required in Australia by anyone working in the construction industry, including:
- Contractors and builders
- Plumbers and electricians
- Engineers and architects
- Inspectors and surveyors
- Metal fabricators and welders
- Construction site traffic controllers (may need a White Card depending on site requirements and state or territory regulations)
- Decorators and painters
- Gardeners and landscapers
- Workers in the demolition industry
- Heavy equipment operators
- Scaffolders, roofers, and others involved in construction-related tasks
Workers involved in dogging, and rigging operations may require additional training and certification in addition to the White Card certification. This could include crane operation, scaffolding, or other specialised skills courses and certifications.
Before beginning work in dogging, rigging, or lifting operations, workers must have the necessary certification and training. They should seek advice from their employer or the appropriate authorities on obtaining the necessary certifications and qualifications.
International students must first obtain a White Card certification if they plan to work in Australia’s construction industry. To earn the credential, they need only enrol in and complete a construction induction training course and test offered by a Registered Training Organisation (RTO) in any part of Australia.
Overall, White Card training is an important foundation for individuals pursuing a career in the construction industry because it provides them with the knowledge, confidence and skills needed to work safely, and effectively on construction sites. A Construction Ready package can then build on this foundation by providing specialised training and experience to prepare individuals for specific roles in the industry.
