Detail Design and Analysis of A Free Standing I Beam Jib Crane 1.5 Loads on Jib crane 1. Trolley load: the weight of the trolley and equipment attached to the trolley. 2. Dead load: the weight if all effective parts of the bridge structure, the machinery parts and the fixed equipment supported by the structure. 3. Lifted load: The working load and the weight of the lifting devices 4. Crane Glossary | ProservCrane Group Dead Load A load on a structure which remains in a fixed position relative to the structure. On a crane bridge such loads include the girders, footwalk, cross shaft, drive units, panels, etc. Deflection Displacement due to bending or twisting in a vertical or lateral plane, caused by the imposed live and dead loads. Diaphragm E-Series Steel Gantry Crane – Spanco assistance specifying cranes that will require seismic and other additional loads or cranes that will operate in high humidity or corrosive environments. Crane shall be designed to withstand: 1. Crane and hoist dead load. 2. Live load capacity equal to net rated hook load. 3. Inertia forces from crane and load movement. 1.4 DOCUMENTS CRANE TESTING REQUIREMENTS FOR PERFORMANCE TESTS L3v = Load hoist dynamic test, main hoist, variable-rated crane. Conduct test L3m at the maximum radius of the crane. L3w = Load hoist dynamic test, whip hoist. Raise and lower test load on each controller point and visually observe smooth control between points.
