Abstract

See full text

A hoisting device or crane can be operated with at least two different maximum loads. The maximum load that can be hoisted in each case is correlated with the hoisting speed in order to prevent the dynamically developed peak load from exceeding the predetermined allowed load limiting values of the components of the crane or the hoisting device.
