The nominal rope diameter ratio to as the basic elements. Taking into account the use of nominal diameter application flexibility, you can not hoist mechanism
limits.
Mobile cranes usually by using a variety of design features, such as. The lifting hook, grab or electromagnetic sucker operation, when the application in order to avoid
Difficulties, given only a minimum ratio, these ratios and crane-independent rating agencies.
