Abstract

A hoist lifting system having planning and monitoring of components. The system monitors one or more components and may have a processing structure and memory storing instructions to configure the processing structure to: receive hoist machine data; determine a rotation speed of a bearing, a travel speed of a rope, a load on the bearing, a friction in the at least one bearing based on the hoist machine data; and store the rotation speed, the travel speed, the load, and the friction in a maintenance database in memory. The hoist lifting system may have the processing structure determine a wear of one or more components.
