The Problem

• Cranes are a regular source of construction and mining accidents causing deaths, injuries and damage due to incorrectly setup and managed lifts.

• The quality of the lift is reliant on the dogman or rigger to accurately depict “plumb” of the hook.

• Even for experienced riggers the lifting scenario may be difficult to judge plumb, causing the load to shift and swing when lifted.

Rigger Assist Benefits

• Rigger Assist improves crane safety and efficiency by taking the guesswork out of setting up and lifting loads.

• Reduction in crane incidents improves workplace safety

• Potential to reduce insurance premiums

• Data logs available for post mortem analysis

• Educate inexperienced riggers about safe lifting techniques

• Speed up lifts and improve efficiency

• Turbine replacement lift 6.5 tonnes, 500 tonne crane

• Job assets between $6-12 million

• 42m radius with live boom

• Excessive potential for incorrect judgment of “plumb” due to length of boom

• Potential for up to 3 feet (90cms) of radius gain

• Hard for rigger to assess angle of winch ropes due to height of crane boom

Lift 1

• Critical to have “plumb” of load 100% accurate when taking weight

• If under/over jibbed the direct result is buckled turbine blades

• Complete replacement operation necessary if this occurs

FE

Lift 1








• Riggers Perception of standing at 90 degrees to boom

• Ability to detect 3 degrees of “over jibbed” boom using “Plumb Gauge”

• Rigger is able to quickly rectify lift situation before damage done to turbine

Lift 1








BA

CDE

• Oil Derek demolition lift 13.5 tonnes, 160 tonne crawler crane

• Potential for crush injury to riggers deemed as “high”

• Load has offset weight distribution on top

Lift 2

CDE

Lift 2

B• Initial rigging of top section

• High/heavy load with “high potential for load shift under lifting operations








BA

CDE

C

Lift 2

• Demolition rigging involves cutting bottom of structure whilst crane holding estimated weight of load

• Result of incorrect assessment of “plumb” whilst detaching load is severe shift of load

• Very “high” potential for crush injury to riggers








BA

CDED

Lift 2

• Once riggers return to bottom mezzanine for lift, it is paramount safety is first due to limited work space

• Force multiplier of load becomes potentially fatal if “plumb” incorrectly assessed

• Riggers perception of 90 degrees “plumb” from bottom of mezzanine for lift

• Almost impossible to assess perfect “plumb”

• Rigger has to account for offset weight

• Rigger able to quickly rectify lift situation before crush injury and damage to plant occurs








BA

CDE

• Heavy transformer lift 65 tonnes, 500 tonne crane

• Job assets up to $10 million

• Load heavy on one end - “high” potential for load shift

• Confined work area

• Potential to damage surrounding structure with movement of load

• Force multiplier of large load has excessive ability to crush/injure surrounding personnel








BA

• View from high standing rigger

• No ability to decipher “plumb” from this position (not 90 degrees to boom)

• View from rigger standing at 90 degrees to boom

• Hard to perfectly assess “plumb” due to height of load

• Rigger able to easily rectify lift situation before 65 tonne load shift uncontrollably

• WiFi or Bluetooth Connectivity

• Capacity in tonnes of crane at specific configuration • Radius of hook-block from centre of slew ring on crane

• “Plumb Gauge” - gives rigger digital display of behaviour of winch ropes in relation to vertical. Accurate display from (-10°) - (+10°), 0° being a perfect lift

• Informative, real-time functional displays

• Colour - illuminated green, or other, resulting in highly visible display day and night
