Spanco PF Series Gantry Cranes offer high capacity, high height, long span, and economical lifting solutions.
These strong, portal frame (PF) cranes can be ideal if:
- Your building can’t support jib cranes or overhead cranes. PF Gantry Cranes are self-supporting and travel directly on the floor.
- Your lifting volume is moderate and can’t justify more expensive, permanently installed cranes.
- You need an economical, versatile lifting system to supplement your existing overhead cranes.
- You rent your facility; these gantries can be relocated in the future.
- Your plant has been “making do” with multiple forklifts. Coordinating too many lifts, especially on heavy or very long loads, is unsafe, inefficient, and time consuming.
Can’t fit a double leg PF crane into your plant due to narrow bays or crowded machinery? Check out our Spanco Single Leg Gantry Cranes.
Power drive options for pf gantry cranes
- V-Track Drives: Two motors drive rigid steel V-groove wheels along a fixed path. See Power Drive Options Kits.
- Guide Angle Drives: Ideal for installations where gantry runs along a wall. Two motors on one side of the gantry drive trackless polyurethane wheels that are led by a small guide angle. The guide angle simply lags into the floor, at the base of the wall. See Power Drive Kits.
- Truly Trackless Drives: When you need to keep your shop floor clear of all tracks or angle guides. A selector switch in the control pendant selectively turns each motor on and off to guide the gantry along.

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 American Welding Society’s (AWS) D1.1/D1.2/D1.6 Standards.
Spanco, Inc. is officially certified as an AWS Certified Welding Fabricator (CWF). This 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 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
Structural Steel Tubing: ASTM A-500
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 designed to L/450
- Jib Cranes: Wall-Mounted Cantilever (300 Series) models designed to L/150, Freestanding (100, 101, and 102 Series), Mast Style (200 Series), and Wall-Mounted Bracket (301 Series) models design to L/450
- Workstation Jib Cranes: Wall-Mounted (WC Series) models designed to L/225, Freestanding (FR Series) models designed to L/150
- Gantry Cranes: All steel series models to L/600, Aluminum models to L/450
Spanco, Inc. is an ISO 9001-2008 Registered corporation. This means that Spanco cranes are manufactured to standards ensuring safety, reliability, and the highest quality. Spanco, Inc.’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 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.
- Adjustments and/or repairs should be made in an area where it will have the least interference with operation.
- Never stand under gantry when disassembling crane.
