Harrington Underhung cranes combine superior
performance with underhung space savings. It's
a rugged design that easily handles today's most
demanding Class "C" applications, including
fabricating, machining, die handling, production,
assembly and maintenance. All bolted assembly
makes installation quick and easy—no welding
required. Most wiring connections are factory installed
or plug-in type. You can rely on Harrington cranes for
durability, reliability and years of trouble-free service.
Count on Harrington to include standard features that
are options on competitors' cranes.

Harrington's underhung geared cranes offer an economical alternative to motorized systems. Side guide
rollers mean these systems operate much easier than flanged wheel cranes. Consider geared operation
where precision control is required, such as die handling or fabrication assembly operations. Geared
cranes are easily upgradable to motorized systems to meet changing customer needs.

Harrington's underhung push cranes offer an economical alternative to other cranes. Side guide rollers
mean these systems operate much easier than flanged wheel cranes. Push cranes are easily upgradable
