JIB CRANES WALL CANTILEVER STANDARD MODEL 300 SPECIFICATIONS

DESIGN FACTORS: The standard capacity rated load of the jib crane represents the net rated load at the hook of a hoist of the same rated capacity as the crane, with a design factor. This design factor for stress in the crane is based on the capacity plus 25% of the rated load for impact and 15% of the rated load for the weight of the hoist and trolley. This was utilized along with the average yield stress of the material to determine the type of design. This design provides for a margin to allow for variations in the properties of material, operating conditions, and design assumptions.

Note: no crane should ever, under and condition, be loaded beyond its rated capacity.

BRACKETS: Each bracket of the wall mounted jib crane is constructed of formed steel. All components are in double shear, including the bolts. All rotating brackets contain bronze bushings and grease fitting.

BEARINGS: The radial load bearings (top of bracket) are s.a.e. 600 bronze bushings with pressure grease lubrication. The thrust bearing is oil impregnated self-lubricating oilite bronze.

PAINTINGS: The jib cranes are painted with one coat of safety yellow, fast drying enamel paint; federal specification #13538.

CONSTRUCTION, MAINTENANCE AND OPERATION: The proper construction procedure, list and type of parts and maintenance instructions are furnished with purchase of the jib crane.

Warning Note: This equipment is not, in any way, designed for lifting, supporting, or transportation of humans. Failure to follow the specified limitations can result in serious bodily injury and property damage.
