Executing an effective maintenance program for crane and hoist assets can be challenging for utilities because of variations in operating context and functional criticality that is provided in different phases of the asset life cycle. This balance of plant equipment is considered non-revenue generating; it is used during critical construction periods and for generating unit overhauls, and can then remain idle for months or years following. The value of a crane or hoist’s function can be non-critical (general material handling), important but redundant (tandem generator room cranes), or critical for flow regulation and overhaul support (spillway hoists and overhead travelling cranes). The failure of critical assets can result in costly project delays, cause equipment damage or contribute to a dam safety emergency if not operational when required.

The purpose of this guide is to provide a textual description of utility best practices with respect to the maintenance program methodology, training, operation, maintenance plan, condition assessments, and modernization of crane, hoist and plant lifting equipment. Utilities will have the ability to modify their practices and customize the template examples provided in the report to execute individualized maintenance programs according to the size of their fleets.

This guide is distinct from previous reports and industry standards because it focuses on the entire life-cycle of crane and hoist assets, incorporating best practices obtained from survey responses from a cross section of participating HPLIG utilities that operate and maintain a combined total of 4500 cranes and hoists.
