It is very likely that you are not investing enough with the maintenance efforts on your production cranes! 

Most organizations do not spend nearly enough on planned maintenance and end up paying far higher costs in unplanned breakdowns.  It’s well documented that investing effectively in hoist and crane maintenance can improve the bottom line significantly, by increasing planned and predictive maintenance to lower the much higher costs of reactive maintenance.  Unfortunately, what level of investment will be optimal to maximize the investment is hard to determine.

Side pulling a hoisted load is an unsafe practice that may cause tragic consequences when bystanders are struck or pinned by the swinging load. Side pulling is written into most operations manuals as a forbidden operational practice because of the inherent danger. In addition to personal injury, intentional and unintentional side loading causes millions of dollars of equipment and product damage every year. Sideloading is also damaging to the hoist as rope guides and hoist drums, as well as hoisting cable, can be easily damaged by the act. There are products available to crane modernization providers that can be installed on new and existing hoists to operationally restrict the ability to sideload a hoist.

Most hoist manufacturers require specific lubricants for their gear cases and have defined time requirement for oil changes.   Since the gear case carries the suspended load and is also the most expensive repair component, it makes absolute sense from a safety and operational perspective to invest in routine analysis of oil to determine the health of the oil and the gearbox components, including, gears, bearings, and seals.   Hoist and crane gearbox oil analysis is a routine activity that is useful for analyzing oil health, oil contamination, and internal gear and bearing wear.

Reducing the potential for collisions between overhead cranes, monorail hoists as well as fixed objects and obstructions such as in-plant office structures has been a challenge for the overhead material handling industry for many years. Until recently it was only possible to minimize the resulting impact from collisions using mechanical means such as bumpers, barriers or limit switches. With current technology, it is now possible to economically prevent these collisions using more sophisticated means in a variety of operating environments.

There is a major controversy within the hoist inspection community when discussing the ANSI requirement of a secondary limit switch on European style hoists, typically sold with only a single upper hook limit switch that is operated based upon drum turns. American National Standards Institute ANSI standard B30.2; Paragraph 2-1.13.5(D) clearly requires a secondary upper hoist limit switch on wire rope hoists when the primary upper limit switch is operated based upon drum turns. Who is right?

Overhead crane runway systems recieve constant loading as well as wear forces that create operational and safety issues over time.  Therefore, the proper inspection of crane runways and their supporting systems is just as important as the inspections of the cranes and hoists traveling on them.

 A crane runway rail’s narrow, dust-covered walking surface is often one of the highest maintenance areas found in any facility. Proper maintenance and inspections of crane and hoist system must include human access to the runway structure and rails.  Many facilities have process machinery, storage rack or other equipment blocking ground access to the runway rails using personnel lifts.
Learn how inexpensive fall protection systems can help you better maintain your runways, increasing productivity  and improve safety as well.

In this article, we answer in detail some of the common questions that users of overhead cranes and hoist have about inspections and inspection requirements.  CRANE 1 believes that a thorough inspection and equipment assessment program in conjunction with preventive maintenance is one of the best investments that you can make.  We answer the following questions:

1)  Why should my company inspect our overhead cranes and hoists?
2)  How often do overhead cranes and hoists need to be inspected?
3)  What qualifications are required to perform crane and hoist inspections?
4)  Do overhead cranes and hoists require load testing?
5)  Do crane runways and monorails require inspection?
