Underhung and Under-running cranes are two ways to refer to the same type of crane. With underhung cranes, the end trucks ride on the bottom flange of the runway beam rather than on top like other types of overhead cranes. With an underhung crane, the runway beam is often suspended from the roof, which eliminates the need for extra floor columns to support the runway. This can be advantageous if floor space and the need to reduce obstructions is a major issue in the factory or warehouse. An underhung crane may even be appropriate with sloped ceilings or multiple crane systems.

1. Is an Underhung or Under-running Cranes Appropriate for you
What are they and when are they appropriate?
Underhung and Under-running cranes are two ways to refer to the same type of crane. With
underhung cranes, the end trucks ride on the bottom flange of the runway beam rather than on top
like other types of overhead cranes. With an underhung crane, the runway beam is often
suspended from the roof, which eliminates the need for extra floor columns to support the runway.
This can be advantageous if floor space and the need to reduce obstructions is a major issue in the
factory or warehouse. An underhung crane may even be appropriate with sloped ceilings or
multiple crane systems.
Underhung cranes can be either single
girder or double girder. Double girder
underhung cranes are often suitable for
longer span or higher capacities.
However, underhung or under-running
cranes are typically limited to lighter
capacities (usually about 10 tons
maximum).
What Crane Type is Right for Me?
The best crane type for your individual
needs is ascertained based on
application and building dimensions (if
the crane is to be fitted to an existing
building rather than a new building).
The most effective way to determine if
an underhung crane is right for you is
to
consult
with
your
crane
manufacturer and installer before
making the final decision about the
appropriate equipment to purchase.
