LOSTPED Load: How much is the unit carrying, pushing, pulling? Is the unit exposed to shock loads? Are there dynamic loads that you might not see from a drawing? Orientation: Is the system horizontal or vertical? What is the plane of travel? Will the orientation affect the lubrication in the system? Do you need to consider safety because of the orientation? Speed: How fast does the system need to move from point A to B? Are there any special acceleration or deceleration requirements? Travel: What is the total travel for the system? Is a long travel needed while most of the work is being done in a very small area? Is it reaching a length of travel that may cause binding or buckling? Precision: How close do you need to be when the system moves or indexes? Do you need high accuracy over the length of the system or high repeatability? Do you need external position feedback to make sure you have reached your location? Environment: Is it exposed to the elements, water, dirt, or other contaminants? What kind of protection is right for the application? Do you need a special maintenance regiment? Duty Cycle: What is the typical cycle time? How often will the customer be running the system? Is it moving continuously or often sitting idle? What type of lifetime is the customer expecting from the system?

Ensure that you have a clear set of parameters required for your need. Understand full process crane is required to do. Check with other previous buyers on performance of crane. Have clear after sales requirements for technical and spares support.

While cost is always an important factor, be careful to consider safety and maintenance factors which may not be as well developed for the lower end products.
