From Hook To Structure: Dogging Vs. Rigging.

A dogman/dogger is the primary person responsible for the ground- level management of crane and/or hoist lifts as a crane operator often has limited visibility from their cab, therefore replying on the dogman to be their eyes and ears to ensure every movement is safe.

Dogman responsibilities include:

• Calculating the weight (mass) and identifying the centre of gravity to prevent the load from tipping or shifting mid-air.
• Choosing the right equipment (chains, synthetic slings, or shackles) and checking for any defects (fraying or wear) before every use.
• Applying the appropriate slinging methods (choke or basket hitches) and calculating the Safe Working Load (SWL) based on lift angles
• Providing clear, standardised instructions using hand signals, whistles, or two-way radios.
• Directing the operator when the load is out of the operator’s direct line of sight – e.g. lifting behind a building or into a deep trench.
• Monitoring the travel path for hazards like overhead powerlines, other structures, or personnel entering the “drop zone”.

Obtaining your dogging licence is critical to obtaining your riggers tickets as it’s a pre-requisite.

A rigger is a skilled operator who uses specialised mechanical equipment to move, place, and secure heavy loads or structures. Their expertise lies in determining load weights, ensuring precise balance, and configuring mechanical rigging systems to transport massive structural components.

A riggers responsibilities include:

• Using specialised equipment like winches, pulleys, chain blocks, and lever hoists to move objects.
• Erecting structural steel, installing precast concrete members, and assembling modular buildings.
• Setting up and dismantling cranes, hoists, and mast climbing work platforms.
• Installing safety nets, static lines, and perimeter safety screens.
• Ensuring the integrity of temporary and permanent structures during the building process.

Rigging tickets are divided into three (3) tiers that build on each other’s technical complexity:

1. Basic(RB): Tasks include all dogging work, plus structural steel erection, safety net and basic hoists.
2. Intermediate(RI): Tasks include basic work, plus dual crane lifts, tilt-slab installation and demolition work.
3. Advanced(RA): Tasks include intermediate work, and covers complex gear like gin poles, shear legs, flying foxes and suspended scaffolds.

While a dogman focuses on the immediate lift, a rigger’s role is broader, including the physical assembly and dismantling of a project’s infrastructure. Both doggers and riggers are vital in forging Australia’s highly skilled workforce, covering a vast range of industries including construction, mining, manufacturing, and entertainment.
