The basic principles of designing of balance weights for cargo cranes

The basic principles of designing of the elementary two- and three-wheel balance weights for cargocranes are considered. The technique allowing on the basis of these elementary balance weights to design balance weights system any complexity is offered. Within the framework of the offered technique the principle of a parity of shoulders of the balance weight is formulated and the algorithm of construction balance weight system is developed. Besides the simple and fast way of definition of forces working in units of the balance weight is offered. The practical application of the offered technique is executed on an example of construction of the six-wheel balance weight.
