Boom cylinders have an important job to do, but they are subject to many potential failures – any of which can cause your machine to shut down and thus hinder your work progress. For example, the barrel inside the boom cylinder can crack or wear over time as contaminants move through it, or the
rod can be damaged by foreign objects or overload the excavator beyond its lifting capacity.
