Preventive Maintenance

Regular Inspection and Preventative Maintenance Programs not only help reduce overall crane maintenance costs but also help identifying problems that could lead to a crane shutdown.

 

Regular inspections, periodic minor adjustments, regular cleaning and lubrication and replacement of worn parts can help insure good performance and operation of your overhead crane.

 

Many factors influence the inspection and preventive maintenance program required for each crane:

Environmental conditions in which the crane operates is a very important consideration in creating a PM program for a crane.  Cranes that are subjected to severe atmospheric environmental conditions such as corrosive vapors, extreme heat or cold, cement or other dust and other airbourne contaminates require more frequent inspection than cranes found in normal conditions.

 

A typical condition requiring special consideration for frequency of inspection and degree of maintenance is an outdoor installation where temperatures vary considerably.  In this environment, condensation can form in the gearcase and cause rusting or corrosion of gearcase components. 

 

Another condition, where vapor may exist, the oil seals, current conductors and other parts exposed to these vapors may also be corroded and adversly affect crane operation.
