Project Overview
Legend Hire was engaged by Russell Skillen Air Conditioning to deliver a precision heavy lift in Rosebery, NSW.
The job involved installing large mechanical components using a 130T mobile crane, requiring exact positioning and maximum stability in a restricted urban environment.
The Challenge
The site presented:
- Limited working space with existing structures and services.
- The need for absolute lifting accuracy during placement of HVAC units.
- Strict safety requirements for crane setup and load control.
The challenge was ensuring total stability and safety under full load conditions.
The Solution
Design
- Lift plan and outrigger layout engineered to site geometry and soil conditions.
- Full outrigger back propping designed to handle dynamic load transitions.
- Compliance with AS 2550.5 (Cranes, Safe Use) and AS 1418 standards.
Supply
- 130T mobile crane supplied, configured for maximum reach and counterweight balance.
- Ground protection and engineered propping pads installed for even load distribution.
- All equipment certified and pre-inspected prior to mobilisation.
Installation & Execution
- Crane setup and back propping executed by Legend Hire’s lifting specialists.
- Lift conducted under strict exclusion zones and weather monitoring.
- Communication between the lift supervisor and the client’s rigging team ensured seamless delivery.
Inspection & Handover
Lift plan, stability checks, and operator certifications provided post-operation.
Final inspection completed with client representative.
Engineering Considerations
Load Calculations
- Calculated crane load paths and outrigger reactions to ground bearing capacity.
- Modelled lift radius, swing angle, and load weight verification before mobilisation.
Safety Measures
- Exclusion zones enforced during lifting.
- Spotters and communication controls in place for all load movements.
- Real-time monitoring of crane pressure sensors and outriggers.
The Outcome
- Lift completed on time and without incident.
- Zero safety breaches and perfect load control.
- Demonstrated Legend Hire’s ability to combine precision, safety, and speed under pressure.
