Moving materials: Crane and hoist safety Overhead and gantry cranes Introduction Overhead and gantry cranes have a horizontal bridge across which a trolley and hoist travels. A gantry crane has one or more legs running on fixed ground rails, wheels, or other runway systems. Gantry cranes can be portable, with load capacities generally ranging from one to 30 tons, width spanning from Has Your Crane or Forklift Attachment Been Welded Correctly … Part of this process might involve welded joints being subject to non-destructive weld testing (NDT) as a final inspection on the welded joint. Ideally, the tradesperson welding the lifting plates on the site bin would have had his or her welds previously qualified and checked by a registered NATA laboratory, proving the weld procedure and the welder qualification. Crane Girder Design Mar 01, 2018 · Crane capacity = 50 tons (CMAA Class D) Bridge weight = 90.8 kips Trolley and hoist weight = 31.2 kips Wheel load = 78 kips (Maximum with lifted load) Wheel spacing = 11.0 ft. Rail weight = 175 lbs./yard Vertical impact = 25% of wheel loads Lateral load= 20% of lifted load + trolley and hoist Longitudinal load = 10% of the maximum wheel loads.

Welding while still rigged to an overhead crane If an insulated hook is installed on the crane, and a ground lead is properly attached to the workpiece, current cannot flow out through the crane. By spots Date 01-20-2010 16:43 In a shop I worked at we used a short nylon choker between the hook and the bridle ring to prevent welding current from traveling through the crane/rigging. Lecture 14.4: Crane Runway Girders – UL FGG The predominant loading is vertical. The crane runway girder is normally directly supported by its seated connection on the column or by means of a bracket. The best way to secure a direct flow of stresses from the crane runway girder to the column or bracket below, with a minimum of eccentricity, is by means of welded brackets, as shown in Figure 2. 1926.1431 – Hoisting personnel. | Occupational Safety and … In addition to the use of hard hats, employees must be protected by overhead protection on the personnel platform when employees are exposed to falling objects. The platform overhead protection must not obscure the view of the operator or platform occupants (such as wire mesh that has up to ½ inch openings), unless full protection is necessary. DESIGN OF CRANE RUNWAY STRUCTURES 3) The way in which load-carrying members interact at connections. There is at present no code of practice, design guide or specification for the complete design of crane gantries. Designers may make reference to a number of sources of information ( CISC, AISC, AISE, etc.) , which define design criteria.

Shock Loading – Shocking Results – ITI This compounding of weight takes its toll on the load’s internal and external structure, rigging attachment points, all rigging hardware, slings, hoist hook, running ropes, drum and entire hoisting system whether overhead or mobile crane. A typical method of shock loading results from turning or flopping a load over from one plane to another.
