On the issue of choosing the electric system of crane lifting mechanisms.
Abstract
The work establishes the feasibility of using a weighted krbkovoho suspension on the crane, providing unwinding of the lifting mechanism when it is released. A method for calculating the weight of the hook suspension is described. It is proposed to lower the empty hook in the mode of uniformly accelerated motion, and the landing speeds should be obtained in the mode of dynamic braking. The electrical control scheme of the crane lifting engine with a weighted hook suspension is given. Figure 1. Bibliographic references 6.
