Series 200 Jib Cranes have been designed for standard duty applications using a hand chain or electric hoist where the live load plus hoist and trolley weight do not exceed the rated full load capacity plus 15%. The Series 200 is highly suitable for general purpose use in the loading, handling and transferring of materials. The total effect of boom deflection is limited in design so as to afford easy and safe hoist travel. Where precision assembly and spotting of the load is required the use of a hand chain hoist is recommended. Structurally designed to meet or exceed the requirements of A.I.S.C. Specifications. The upper head and lower roller bearings are precision, large capacity and designed for 10,000 hours average life. The bottom roller assembly is adjustable for leveling boom when necessary. 360° rotation electric current conductors or air supply swivel connectors can be furnished where continuous uninterrupted rotation is desired.
