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-Mounted 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 mounting foundation, only a standard 6-inch reinforced concrete floor.
- Available with power rotation on all models.
200 Series Mast Jib Cranes — Full Cantilever: To provide maximum clearance underneath it, the cantilevered boom is mounted at the top of the mast.
201 Series Mast 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 Jib Crane Features
- Utilizes a 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 ready lubrication and to aid rotation.
Options for SPANCO Mast-Style Jib Cranes

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.
- 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 form the recommended foundation size or installation recommendations without first consulting a qualified professional. Failure to check this item can result in severe bodily injury or death.
- Do not impact end stops at speed.
- Do not 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.
