Additional information

Mast-Style Jib Crane Bid Spec

. Product: Spanco Mast-Style Jib Cranes are floor supported and top stabilized with a steel
beam mast connected to a 360-degree rotating steel beam boom, which covers a circular
work area. Mast-Style Jib Cranes can be full cantilever or drop cantilever and manually
operated or motorized.
B. General Design Standards: Spanco Cranes are designed in conformance with the following
applicable standards:
1. Jib Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, and
CMAA 74.
C. Standard Equipment Specifications: List other specifications related to the product and
application including options, accessories, and customizations [Mounting, Hoists, Electrical].
1. Working Span: [Working span is determined by the amount of actual working area
needed. The working distance, or hook distance, is approximately one-half the trolley
length from the end of the I-beam and is the same distance from the top beam
assembly.]
2. Area of Rotation: [Freestanding and Mast-Style Jib Cranes offer 360-degree rotation.]
3. Capacity: [The maximum weight of the application should not exceed the design weight.
Load weights should be predetermined to avoid buying unnecessary capacity.]
4. Height: [Under-boom height is considered the distance from the floor to the underside of
the boom. The size of the hoist and the lifting distance should also be considered. The
overall height is measured at the highest point on the crane after installation.]
