Gantry Crane Structural Analysis

LOCATION
Port Uzniy, Ukraine

CRANE TYPE
Portal Boom Crane
LIFTING CAPACITY
40 t
ASSESSMENT
Structural Analysis / Productivity Upgrade

PROJECT OVERVIEW

The Challenges

The crane was assessed to determine the possibility of operating with the maximum lifting load of 40 t at all outreaches.

Initially, the maximum outreach for SWL 40 t had been limited by the manufacturer to 25 meters. The engineering assessment was therefore performed to evaluate the crane structure and determine the possibility of increasing the operating outreach while maintaining the required structural strength and stability.

FIELD MEASUREMENTS

Strain Gauge Measurements

ENGINEERING VERIFICATION

Crane Stability & Wheel Load

PROJECT OUTCOME

Engineering Assessment Result

The structural assessment included finite element analysis of the main crane structures, crane stability verification, wheel load calculations and strain gauge measurements. The engineering study was performed to evaluate the possibility of operating the crane with a 40 t lifting load beyond the original 25 m outreach limitation
