3 Ton A-Series Gantry Crane - Adjustable Height, All-Steel Construction, 10' - 40' Span

3 Ton A-Series Gantry Crane - Adjustable Height, All-Steel Construction, 10' - 40' Span

Product Description

No brace legs means greater clear spans. Adjustable heights and adjustable spans available. Steel or aluminum models.

Spanco A Series Gantry Cranes are portable, lightweight, low-cost lifting solutions with sturdy “A” frame designs.

A Series Gantry Cranes have greater clear spans because they don’t require four brace legs like our T Series. (Note: if you need the ability to adjust the crane’s tread, see our T Series Gantry Cranes.)

Spanco A Series Gantry Cranes are available in three makes:

Makes Capacities Heights Under I-Beam Span Lengths
Steel with Adjustable Height up to 10 tons up to 16' up to 40'
Steel with Fixed Height up to 10 tons up to 16' up to 40'
Aluminum with Adjustable Span and Height up to 3 tons up to 12.2' up to 20' (on 1-ton models)

*Longer custom spans available

Aluminum Gantry Cranes: Weigh as little as 116 pounds, making them ideal for fast crane relocation.

Features of Spanco A Series Steel Gantry Cranes

  • Crane Height Adjustments: Adjusts in six-inch increments, using spring-loaded steel locking pins that automatically engage when height positioning holes are reached. Adjust heights for specific lifts, uneven floors, or to move through doorways.
  • Adjustable Spans: Standard on aluminum cranes, optional on steel cranes. Allows crane to be shortened for transport down narrow aisles.
  • Heavy-Duty Casters: Four-position, swivel-lock casters with moldon polyurethane wheels for excellent floor protection.

Options for Spanco A-Series Gantry Cranes

  • Adjustable Span Kits: Convert your steel fixed-span gantry to an adjustable span. DIY installation requires no drilling of I-beam.
  • Alternative Caster Styles & Wheel Brakes: Available upon request.
  • Height Adjustment Winch-Hoist Kits: Includes two LUG-ALL™ cable winch-hoists to quickly and easily change I-beam height. Note: For use only on Spanco A Series Steel or Aluminum Gantries under no-load conditions.
