The crane has recently undergone an examination by a local engineer. Their report was based on the operation of the lifting mechanism, and it did not consider the support structure. comment on what should be considered when planning for, and carrying out, lifts using the overhead crane using relevant information from the scenario.

An overhead crane, operating on rails, is used for handling heavy and/or awkward items that need be suspended during the coating process. The crane is electrically powered and is operated by a hanging pendant control that is very dirty. The controls are simple to use with colour-coded buttons indicating the operation that they perform. The electrical system has been known to 'trip' and, sometimes, the crane has stopped working mid-way through the process. This tends to happen during warm weather when the oven is in operation. All the workers know how to operate the crane, but it is only used occasionally. The crane has a safe working load (SWL) of two tonnes. Workers use their own judgement to estimate the weight of the loads to be lifted by the crane. Lifting accessories can be found on the floor next to the wall and close to the crane. There are various types including, chains, hooks, and webbing. The workers select which they think is the best accessory, and then attach the workpiece to the crane for lifting. The suspended workpiece is then coated with the powder and subsequently moved using the FLT into the oven for curing. The workers have noticed that there is some movement in the rails attaching the overhead crane to the structure of the building when it is used. As the crane travels along, the rails flex at a certain point. This flexing appears to be getting worse. The crane has recently undergone an examination by a local engineer.
