Freestanding Workstation Overhead Bridge Cranes

LOOKING TO STREAMLINE YOUR MANUFACTURING PROCESS?

Spanco Freestanding Workstation Bridge Cranes are the perfect ergonomic solution for extending lifting coverage and providing full access of movement. Our Freestanding Workstation Bridge Cranes can replace multiple cranes with one fluid system for improved efficiency and productivity.

Spanco Freestanding Workstation Bridge Cranes provide highly-effective cost-efficient lifting and moving solutions, especially when:

• You need overhead crane coverage for a large area––up to 40-feet wide and with unlimited length. With interconnected parallel systems, you can cover your entire building
• You rent or lease your building. Our bolt-together freestanding systems can be readily relocated, either within your plant or in an entirely new location
• You want to be able to easily expand or modify your overhead crane system
• Your roof support is inadequate for a Spanco Ceiling-Mounted Bridge Crane. Typically, a standard six-inch thick reinforced concrete floor is all that’s needed for our freestanding workstation bridge cranes for non-seismic applications

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 B30.17, AWS D1.1/D1.6, and MMA MH27.2
• Gantry Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.17, AWS D1.1/D1.2/D1.6, and CMAA 74
• Jib Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.17, 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.

Fabrication Standards:

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.

Material Standards:

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.

Deflection Guidelines:

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), Wall-Mounted Cantilever (300 Series), Articulating (400, 401, and 402 Series), and Foundationless models (600 and 605 Series) 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

Quality Standards:

Spanco is an ISO 9001:2015 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.
• Applications involving vacuums, magnets, or other high impact lifters are considered severe usage (continuous service) and require special design considerations. Please see the High-Impact Lifting Systems Protocol and contact factory for special design pricing.
• To prevent trolley/end truck running out of the track, do not operate crane without end stop bolts firmly secured in place on each end of the bridge crane track and on each end of each runway track.
• Runway end stops must be aligned longitudinally so bridge hits end stops simultaneously.
• Do not locate splice joints more than 12” from the runway support centers when aligning plain track runways.
• Do not cantilever the runway track ends more than 12” beyond the runway support centers (not including festoon storage area) on plain track runways.
• Do not locate truss splice joints more than 48” from the runway support centers when aligning trussed track runways.
• Do not cantilever the trussed runway ends more than 48” beyond the runway support centers (not including festoon storage area).
• Do not impact end stops at speed. Only impact end stops with caution.
• Never use end stops for repetitive bridge impacts.
• Do not skew bridge in runways.

Do not operate hoist or crane if cotter pins are not in place and properly bent over on both sides of hoist trolley. Check regularly that the cotter pins are in place and securing the hoist on the hoist trolley.

Applications involving vacuums, magnets, or other high-impact lifters are considered severe usage (continuous service) per the Monorail Manufacturers Association (MMA) and may require special design considerations. See below.

• Electromagnet lifting systems require the system capacity to be derated by 50%.
• Vacuum lifting systems that use an electric hoist never require the capacity to be derated.
• Vacuum lifting systems that use vacuum hose trolleys require the system to be derated by 50% if the system has any of the following attributes. Please contact Spanco with any questions about the system attributes below.
  • The operational time (system is in motion) is consistently greater than 50% of the work period and the lifted load is consistently greater than 50% of the rated capacity.
  • The equipment performs more than 20 lifts per hour.
  • The average lift is 15 feet or more.

NOTE: Applications that exceed 40 lifts per hour can be problematic due to unusually high-cycle rates. If an application exceeds 40 lifts per hour, please provide as much information as possible about the lifting process and the item(s) being lifted.

Vacuum lifting systems that use vacuum hose trolleys and do not have any of the system attributes listed above do not require the system capacity to be derated.
