Mast-Style Jib Cranes
- Crane Rotation: 360°
- Capacities: up to 5 tons on standard models; up to 10 tons custom
- Spans: up to 20’ standard; up to 40’ custom
- Heights: up to 20’ standard; up to 40’ custom (distance from floor to overhead support)
Spanco Mast-Style Jib Cranes provide full 360-degree rotation while eliminating the cost of a special foundation, which can cost more than the crane.
As a lower cost alternative to freestanding jib cranes, these full-feature mast-style cranes:
- Are bolted to the floor and existing overhead support structure (e.g., steel beams)
- Require no special foundation, but only a standard 6-inch reinforced concrete floor
- Are available with power rotation on all models
200 Series Mast-Style Jib Cranes—Full Cantilever
- To provide maximum clearance underneath it, the cantilevered boom is mounted at the top of the mast.
201 Series Mast-Style Jib Cranes—Drop Cantilever
- Identical to the 200 Series with the addition of side-plate connections to permanently “drop mount” the boom at any specified height on the mast. Drop cantilever booms allow for clearance from overhead obstructions that are located below the top of the mast.
MAST-STYLE JIB CRANE FEATURES
- Uses wide-flange beam or I-beam for the boom and a wide-flange beam for the column
- The top assembly has self-aligning spherical bearings
- The bottom assembly has bronze bearings and bronze thrust washers
- Both bearing assemblies are provided with grease fittings for lubrication to aid rotation

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), 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
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.
- The rated load of the hoist as marked on the hoist must not exceed the rated capacity of the jib as labeled on the boom. Do not install a hoist with a capacity greater than that of the jib.
- It is solely the customer’s responsibility to provide suitable mounting supports for the jib crane. Spanco recommends that the customer consult a qualified professional architect or engineer in your local area to determine the adequacy of the building support. There should be no deviation from the recommended foundation size or installation recommendations without first consulting a qualified professional. Failure to check this item can result in serious bodily injury or death.
- Do not impact end stops at speed. Only impact end stops with caution.
- Never use end stops for repetitive boom impacts.
- To prevent trolley from running off of the boom, do not operate crane without end stop bolt firmly secured in place on the end of the boom.
- 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.
- Inspect jib for missing or broken parts before operating.
- Do not adjust or disassemble crane when jib is under load.
- When moving jib, position the load in the center of the boom.
- Be certain the load is directly beneath boom 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 jib when disassembling crane.
