Cranes are typically designed for the specific building
and application. In order to design the crane that best fits your needs you
will need to look at how you will be using you crane and answer the
following questions.
We have formulated these questions because we have found that every customer
has differing criteria they need to meet.
Use per hour
and day are of prime importance in the design of a crane. All equipment we
sell is designed for industrial usage. Some is designed for very infrequent
use while other is designed for continuous usage. Because the cranes are
designed for industrial even misapplied equipment will typically last for
several years, a well designed crane will last over 30 years.
Maximum uses per hour and travel distance in each
direction. If you lift from the ground to the bed of a truck you would
lift about 5 feet each lift times X lifts and travel 50 feet in bridge
motion and 20 feet in trolley direction.
Typical use per day.
Average and maximum weight lifted.
In many cases speed
is very important. Cranes used in volume production should be fast. Cranes
positioning motors on mounts must be able to move slowly. Variable drives
can be used when both speed and positioning are required.
Explain how the crane will be used and if there are
any special speed requirements.
Are there any
environmental factors to take into consideration.
Outside usage, usage over plating tanks, long periods of no use (more than
one month)?
What is the area
you wish to cover? The hook is typically limited to 3 feet from the
building wall although this can vary depending on requirements. Hook height
is very critical. You must take into consideration the height of the load
plus any equipment that you must pass over plus the height of any slings you
use to attach to the load.
Draw an outline of the area that must be covered by
the crane.
What is the minimum hook height.
