TC/American Free Standing Crane System Case Study

The Problem: The customer wanted a Free Standing Bridge Crane system so their fork trucks would not have to handle the material they were...


Crane Modernization

Upgrading the systems on your bridge crane can be very beneficial for the personnel in your facility as well as production.  New control systems enable feedback from the crane to be monitored remotely by your technicians over their computers.  This can be very helpful in making sure things are working properly and your employees are using the crane the way they should. 



As the operator for one or multiple pieces of overhead material handling equipment, you know best how they act.  On a daily basis, you should look for any abnormalities.  Once operating, you should also listen to the equipment to make sure that the brakes, motors and safety features are all working properly.  Make sure to note any abnormal signs of wear and alert the appropriate personnel at your facility if something does not look right. 


This inspection is typically done by the operators since they are using the equipment frequently.  The monthly inspection is primarily a visual check of the condition of the unit and its safety features.  Generally, no cabinets or enclosures are opened. You want to make sure and check the wire rope or chain for any kinks, breaks or deformation.  You also want to make sure and check the units limit switches, lights, horns and other safety features.  Make sure to note any abnormal signs of wear and alert the appropriate personnel at your facility if something does not look right. 


A lot of customers who have higher production rates elect to have semi-annual and even quarterly inspections done in addition to the other types listed.  This particular inspection is a duplicate of the Annual Inspection where all aspects of the units are checked out.  The section below has more specific information on what you can expect.


The annual inspection is required to make sure that all of the overhead material handling equipment is in safe, working order and should be performed by an outside source.  Each piece of equipment is thoroughly inspected and written reports will be given to the point of contact for their records.  For this inspection, technicians will look at the motors, gears, control cabinets, electrical systems, structural integrity and any other features specific to the piece of equipment.  While some problems can be fixed immediately, others can be time consuming thus leading to downtime.  By having the personnel at your facility check the equipment on a regular basis, these downtimes can be structured into shutdowns and production can proceed uninterrupted.
