Heavy equipment mechanics work on large earth-moving machinery, specializing in engines or hydraulic systems. Repairs require cranes and hoists, and tools are expensive. Working in pairs or teams is necessary due to the size and weight of parts. The job is dangerous and may require working at heights or in confined spaces.
A heavy equipment mechanic works on all aspects of large types of earth moving machinery. Large excavators, front loaders and track hoes are all serviced by a heavy equipment mechanic. Some types of heavy equipment mechanics specialize in engines and powertrains, while others focus their attention on hydraulic systems. Regardless of their area of expertise, a heavy equipment mechanic works on very large machines and uses some very large tools to make even minor adjustments.
One of the downsides of becoming a heavy equipment mechanic is the size and weight of the parts being serviced. Often, even the most basic repair requires the use of a crane or hoist to maneuver the part into position. For example, the basic task of changing a tire by a heavy equipment mechanic might involve a large crane to lift a tire that might weigh more than the average family sedan.
Tool costs are also incredibly high for the heavy equipment mechanic. A single wrench can cost as much as a complete set of tools for the average auto mechanic. While some auto mechanic tools are also used by the heavy equipment mechanic, the vast majority of tools used are based on the requirements for removing and replacing bolts and nuts the diameter of an automobile tire.
Many heavy equipment mechanics work in pairs or even teams due to the incredible size and weight of the parts being worked on. It usually takes a couple mechanics to get the key into a fastener used on this equipment. The size of the tools makes field service an emergency situation only. Whenever possible, the equipment is taken back to the maintenance shop to be repaired. There are few parts that can be repaired without the use of specialized lifting equipment and tools.
Some problems a heavy equipment mechanic might encounter that rarely affect a typical auto mechanic are a fear of heights and claustrophobia. When servicing some types of heavy equipment, the mechanic may be taller than the roof of his family home. Additionally, many tasks performed on the engines of this large piece of equipment require the mechanic to actually crawl on the engine to make repairs. It is for these reasons that the job of a heavy equipment repairman is dangerous. These mechanics must trust and rely on their co-workers for their personal safety and accurate equipment diagnostic conclusions.
