Aluminum Gantry Cranes
- Capacities: up to 3 tons
- Adjustable Height Under I-beam: up to 12’ 4"
- Adjustable Spans: up to 20’ on 1-ton models and 15' on 2 and 3-ton models
Starting as light as 116 pounds, Spanco Aluminum Gantry Cranes are lightweight, portable, and extremely stable under load.
These Spanco All-Aluminum Gantries quickly assemble and disassemble, making them popular with contractors who need highly mobile lift equipment that they can take in their service trucks.
Just one or two workers can typically move a disassembled crane up stairways, onto roofs, or in other challenging locations. When on location, the gantry cranes are rapidly assembled, ready to lift, and able to position heavy objects precisely, such as bulky HVAC units.
Because they are corrosion resistant, aluminum gantries are also ideal for refrigerated areas and other controlled environments, making them increasingly popular with HVAC contractors.
FEATURES OF SPANCO ALUMINUM GANTRY CRANES
- Crane Height Adjustments: Adjusting in 6-inch increments, height adjustment kits use 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, adjustable spans are optional on steel cranes; adjustable spans allow the crane to be shortened for transport down narrow aisles
- Heavy-Duty Casters: Four-position, swivel-lock casters with moldon polyurethane wheels provide excellent floor protection
- Options and Components
- Pneumatic Tires: Either single or dual; perfect for soft roofs and uneven surfaces
- Alternative Caster Styles and 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: These kits are for use only on Spanco A-Series Steel or Aluminum Gantries under no-load conditions.

General Design Standards:
Spanco cranes are designed in conformance with the following applicable standards:
- Workstation Bridge Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, AWS D1.1/D1.6, and MMA MH27.2
- Gantry Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, AWS D1.1/D1.2/D1.6, and CMAA 74
- Jib Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, AWS D1.1/D1.6, and CMAA 74
All Spanco cranes have a design factor of 15% of the allowable capacity for the weight of the hoist and 25% for impact.
All welding performed during the manufacturing of Spanco cranes meets the following American Welding Society’s (AWS) standards: D1.2 for aluminum and D1.1 for steel.
Spanco is officially certified as an AWS Certified Welding Fabricator (CWF). This certification means that not only are all welders AWS Certified, but all processes and procedures adhere to AWS CWF requirements. Examples of requirements include annual calibration of all welding machines and Level 2 visual inspections on all load-bearing components.
All aluminum used in the manufacturing of Spanco cranes meet ASTM International specification ASTM B308 for 6061-T6 aluminum.
All steel used in the manufacturing of Spanco cranes meets the following applicable ASTM International specifications:
Structural Steel Shapes: ASTM A-36
Structural Steel Pipes: ASTM A-53 Grade B
Structural Square and Rectangular Steel Tubing: ASTM A-500 Grade B
Steel plate and round bar used in Spanco cranes have minimum yield strengths of 36 KSI
Surface Preparation & Painting Procedures:
Spanco adheres to the standards of the Society for Protective Coatings (SSPC) for all product surface preparation. Prior to painting, all Spanco crane components are deburred and descaled using power tools equipped with sanding discs and wire wheels. Components are then washed utilizing a high-pressure/high-temperature biodegradable degreaser solution. Parts are wiped clean and allowed to dry before the painting process. During painting, all components surfaces are coated with a quick drying, semi-gloss enamel, applied to a minimum dry-film thickness of 2 to 3 mils. A finishing coat is applied with a hot, airless, electrostatic spray paint system. Painted components are cured at air temperature.
The following guidelines for deflection and stress are followed by Spanco engineers during the crane design process:
- Workstation Bridge Cranes: All models are designed to approximately L/450
- Jib Cranes: Freestanding (100, 101, and 102 Series), Mast Style (200 and 201 Series), and Wall-Mounted Cantilever (300 Series) models are designed to approximately L/150; Wall-Mounted Bracket (301 Series) models are designed to approximately L/600 at midspan
- Workstation Jib Cranes: Wall-Mounted (WC Series) models are designed to approximately L/225; Freestanding (FR Series) models are designed to approximately L/150
- Gantry Cranes: All steel series models are designed to approximately L/600; Aluminum models are designed to approximately L/450
Spanco is an ISO 9001-2008 Registered corporation. This means that Spanco cranes are manufactured to standards ensuring safety, reliability, and the highest quality. Spanco’s ISO designation also allows for continuous improvement based on customer feedback.
- Inspect entire system annually or more frequently as defined by OSHA 1910.179. Inspection must be performed by a qualified person. Failure to do so may cause serious injury or death.
- This equipment, used as a crane, is not in any way designed for lifting, supporting, or transporting humans. Failure to follow specified load limitations can result in serious bodily injury or death.
- Inspect gantry for missing or broken parts before operating.
- Ensure the rated capacity is clearly labeled on each side of the I-beam.
- Do not lift more than the rated capacity.
- Do not adjust the height or disassemble crane when gantry is under load.
- Do not load gantry on an incline.
- Do not push or pull gantry with a forklift or other vehicle.
- Do not allow the load to swing or roll against support members.
- Do not anchor legs to the floor.
- Do not lift gantry when fully assembled.
- Push the gantry, not the load.
- When moving gantry, keep load as close to the floor as possible and position the load in the center of the I-beam.
- Be certain the load is directly beneath beam before load is lifted. Do not pull sideways on crane.
- Ensure the load is not attached to the floor and remove any obstacles that impede lifting.
- Secure trolley and hoist in the center of I-beam when adjusting height.
- Adjustments and/or repairs should be made in an area where it will have the least interference with operation.
- To prevent the trolley from running off the I-beam, do not use without end stops bolted in place.
- Never stand under gantry when adjusting height or disassembling crane.
- When moving the legs inward, the distance between the A-frames should never be less than the caster frame width and never less than half the total I-beam length.
