Eilbeck Cranes is seeking a Structural Engineer to lead our design operations in Moorlands, Ingleburn. You will own the end-to-end engineering process—from initial quotes to final compliance.
The role requires 5+ years in crane structures and hands-on experience with SpaceGass, Strand7, SAP2000, AutoCAD, and SolidWorks, plus knowledge of AS 4100, AS/NZS 1170 and CMAA 70/74. Opportunity to influence cost-efficiency and production quality.
OPEN FOR SPONSORSHIP FOR THE RIGHT CANDIDATE! CALLING STRUCTURAL ENGINEERINGS WITH EXPERIENCE IN CRANES!!!!
Eilbeck Cranes is seeking a fulltime Structural Engineer to lead our design operations in Moorlands, Ingleburn. You will own the end-to-end engineering process—from initial quotes to final compliance.
Must know and actively work with the standards that govern crane and runway design in Australia and internationally:
Crane-Specific Standards
CMAA 70/74 (USA) — Bridge cranes and gantry cranes
AS 2550 series — Safe use & operation (for integration)
AS 4100 — Steel structures
AS/NZS 1170 — Structural actions
Part 1: Dead/live
Part 2: Wind
Part 3: Crane loads / dynamic effects
AS 3990 — Mechanical equipment steels
AS/NZS 5100 — If runway integrated into a building/bridge structure
Welding standards:
AS/NZS 1554.1 — Structural welding
AS 1554.5 — Welding of cranes & lifting equipment components
Must fully understand non-building load cases, which are unique to crane structures:
Dynamic & Fatigue Actions
Impact factors
Long travel/ cross travel acceleration loads
Skewing forces
Fatigue regions in welded joints
Wheel loads under–
Unbalanced loading
Trolley eccentric loading
Side thrust (CT braking, skewing)
Runway Beam Loads
Vertical wheel loads (static + dynamic)
Horizontal loads (transverse & longitudinal)
Crane surge and braking forces
Lateral wheel loads per FEM or AS 1418
Fatigue from repetitive cycles
Rail bending + local bearing/stress checks
Connection design for runway brackets or cap channels
For crane structures, should be proficient in:
Structural Analysis
SpaceGass
Strand7
Robot Structural Analysis
RISA
SAP2000
ANSYS (if doing high-fidelity fatigue studies)
Design/Detailing
Advance Steel
SolidWorks (for trolley/hoist frames)
AutoCAD
Specialised Crane Tools (optional but valuable)
FEA for girder stability (lateral torsional buckling, distortional buckling)
Wheel load calculators (custom or FEM-based)
Girder Design Requirements
Welded box girders, RHS, plate girders, or hot-rolled profiles
Lateral torsional buckling calculations
Distortion under trolley eccentric loading
Fatigue life calculation for welded joints
Deflection control
Vertical (usually L/1000 to L/750 depending on standard)
Lateral (strict to prevent skewing)
Local Checks
Local web bending under wheel loads
Web crippling
Web buckling
Flange local bending
Stiffener design to address all above
Runway Beam Requirements
Clip weld design and fatigue
Beam bending + torsion
Lateral loads from crane skewing
Fatigue class assignment (FEM group 1–5)
Supporting Structure
Portal frames
Columns & brackets
Vibrations & resonance checks
Anchor bolts & base plates
Runway-to-building interaction
Must know how their design will be built:
Welding
Selecting correct weld sizes, types & fatigue classes
Controlling distortion in welded plate girders
Heat input considerations
NDT requirements (UT, MT)
Rail alignment tolerances
Wheel-to-rail geometry
End carriage alignment
Inspection & QA
WPS/PQR compliance
Test certificates
Material traceability (plate, bolts, weld consumables)
Must have practical familiarity with:
How cranes actually operate in the field
Fatigue failures in crane girders
Realistic dynamic factors beyond textbook assumptions
Maintenance issues (cracks, wheel wear, runway alignment)
***An engineer without industrial crane experience will miss many of the load cases and fatigue issues that are essential.
