Select which Tool you would like to use

Use these quick tools to help check common dogging, rigging and lifting calculations before a VOC, toolbox talk or site assessment. These calculators are designed to give simple, easy-to-understand guidance for sling selection, load weight, angles, reeving, crane signals and basic lifting planning.

Calculators

Rigging gear selector

Choose the right lifting gear by entering basic load and lift details to help guide your rigging setup.

Sling angle factor calculator

Work out how sling angles affect tension so you can better understand the load on each leg.

Reeve factor calculator

Check how reeving or choking a sling can reduce its effective lifting capacity.

Reference Guides

Crane signals

No radio? No problem. Learn common crane hand signals and whistles used on site so doggers, riggers and operators can communicate clearly.

Powerline clearance distances

Quickly check state-by-state guidance for safe working distances near overhead powerlines.

Material weights lookup

Quickly estimate the weight of common materials to help plan safer lifts and select suitable gear.
