Heavy Duty Class C Single Girder
Series 3 Underhung Geared Complete 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.
Many benefits from more features:
Complete crane system includes:
• Ideal for precision spotting requirements where motorized
operation is not necessary.
• End trucks come standard with bumpers, drop stops,
and rail sweeps.
• Standard rubber bumpers on cranes and motorized trolleys
comply with ASME requirements.
• Drive shaft assembly with hand wheel and hand chain.
• Standard bridge beam assembly with bracing and
capacity labels.
• Side guide rollers reduce wheel friction and noise, providing
smooth crane travel and increased wheel and runway life.
• Trolley hoist available in a wide selection of styles.
• Power supply to trolley hoist (if required).
• Optional runway electrification.
• Electric hoists with ASME H4 rating maximize lifting
capability while minimizing downtime and expense.
• Sealed hoist and trolley motors enhance motor life and
minimize repair costs.
• Documentation, including assembly and installation
instructions, crane operator’s guide, and owner’s manuals.
• Touch-up paint.
Capabilities to count on:
• One year warranty.

• Capacities through 5 Ton and spans through 45 feet.
• Motorized trolley speeds: 40 or 80 ft/min single speed,
80/20 ft/min dual speed or variable speed. Manual trolleys
also available (push or hand geared).
• Suitable for use on S or W shaped beam (patented track
models available).
