Gorbel's I-beam Jibs are ideal for heavier loads from 1 to 5 tons (heavier capacities available, contact the factory).  They are also available in motorized or manual rotation. Economically provide hoist coverage for individual use in bays, along walls or columns, or as supplements to an overhead crane or monorail system. Capacities from 1/4 ton to 5 tons, with spans up to 30 ft. Require a structurally adequate wall or column to support the jib. Require sufficient clearance above the boom throughout its arc to accommodate the tie rod suspension. Utilize I-beam boom assemblies for heavier capacities and longer spans.
