Test of Horizontal Force in Cart Balance Beam of Quayside Container Crane

ABSTRACT Qiao, Z.; Dong D.; Kuai, X., and Zou, J., 2015. Test of horizontal force in cart balance beam of quayside container crane. As cracks occurred widely on the webs of cart balance beam of quayside container cranes, a proposal has been offered that we should know about the value of horizontal force of quayside container crane under operating conditions based on the force analysis. In view of this, a site test has been carried out. By testing the variation of stresses of cart balance beam under different working conditions, the scope of horizontal force has been obtained. In the end, the factors which may influence the variation of horizontal force have been discussed.
