The hoisting mechanism changes its speed via switch of control console. Thus, ideal hoisting speed and accuracy of slow emplacement are achieved. Its high-speed lifting weight should be no more than 1.6t and medium and slow speed lifting weight no more than 4t, controlled automatically by electrical system of FKDX multifunctional limitator.
