Design and Development of Buffer by Analyzing Collision Force to Resist Jerk Impact on Crane Operator in EOT Crane with Cabin

Abstract

The design of crane buffers for the Electric Overhead Travelling Crane with cabinwere studied during this investigation. This leads to analyze the buffer system as a decoupled system for ease of operator working in the crane cabin.
The maximum end buffer impact force was determined for a chosen level of reliability based on the responses from the sensitivity analysis using the Lagrange Multiplier method. These maximum end buffer impact forces are then compared with the forces prescribed by the codes. Like SABS 0160, SANS 10160 the end buffer impact force obtained from the constraint optimization technique for a aim to achieve level of reliability of ? =3.
It is observed from analysis that the buffer collision force for hydraulic buffers is within limit which is suitable for crane with cabin.
