A work platform for use in performing maintenance while supported on an overhead crane. The work platform is particularly useful for performing maintenance on overhead cranes located in areas where normal lifting equipment and/or scaffolding cannot easily access the overhead crane. However, the work platform is also useful for performing maintenance on equipment and/or structures in the vicinity of overhead cranes, and on overhead cranes located in areas without accessibility problems. The work platform is hoisted for placement on support structure of the overhead crane by hoist apparatus of the overhead crane. When positioned, the work platform may be fully supported on the support structure of the overhead crane.
