Kinematics and Luffing Moment of Lemniscate Type Crane with Boom Driving

Abstract:

The lemniscate type crane is fabricated by Figee B.V. of the Netherlands. There are great differences in outward appearance, geometric shape, luffing performance between lemniscate type crane and ordinary double-link type crane. Lemniscate type crane has some advantages, i.e. lower centre of weight, practical and reasonable structure, strongly anti-wind and easy operation. Based on inverse design and theory of mechanism, instant centers of velocity, luffing locus and moment of lemniscate type crane is studied and solved. The equations of kinematics and luffing moment are obtained.
