Overhead Crane Safety

Overhead Crane Safety. PPT-080-01. 29 CFR 1910.179. Bureau of Workers’ Comp . PA Training for Health & Safety (PATHS) Overhead cranes are used in many industries to move heavy and oversized objects that other material handling methods cannot.

All new overhead and gantry cranes constructed and installed on or after August 31, 1971, shall meet the design specifications of the American National Standard Safety Code for Overhead and Gantry Cranes, ANSI B30.2.0-1967, which is incorporated by reference as specified in §1910.6.

Inspect the overhead crane thoroughly, especially to the structural elements of the overhead cranes where the will be subjected to stress during the overhead crane load testing. A visual inspection to the crane runway, track, powder conductors, collectors and switch gear should be conducted before the load testing.

Normal stress of point (1): The lifting capacity of the overhead crane can achieve 1000t, and the gantry crane 900t, to meet all kinds of project need.

Jan 22, 2018 · Ultimately, providing training for your overhead crane operators is the most important thing you can do to make your overhead lifting program safer. A 30-year old crane with single or dual speed drives can be operated just as safely as a brand new crane with variable frequency drives and a collision avoidance system.

Crane Girder Camber – IMS

Internal Residual Stress Weld shrinkage from girder fabrication creates zones of longitudinal residual stress at (or near) the yield point. This locked‐in stress will cause a slight camber loss after load testing. This type of camber loss is a one‐time event and is too small to measure.

According to the bridge frame structures, overhead crane can be grouped into truss overhead crane, box type overhead crane and tube type overhead crane. The materials of the bridge frame can be the general carbon steel such as Q 235 –B and general low alloy steel, such as, 16 Mn, etc. lknHenan Dongqi Machinery Co., Ltd

(Overhead cranes are defined by OSHA 1910.179(a)(8) as a crane with a movable bridge carrying a movable or fixed hoisting mechanism, and traveling on an overhead fixed runway structure.) Analysis of overhead crane accidents reveals three common safety hazards that every company using overhead lift systems should be aware of to keep their

rail. This type of crane hoist is used to move a load horizontally. Overhead crane: A crane with a movable bridge carrying a movable or fixed hoisting mechanism and traveling on an overhead fixed runway structure. Rated Load (Capacity): The maximum load designated by the manufacturer for which a crane or individual hoist is designed and built.

Apr 04, 2014 · On the overhead cranes that I have performed the stress analysis, the manufacturer of the crane procured pre-certified gearboxes. See the crane codes such as CMAA-74 (2010) for design guidance. Gearing is addressed in Section 4.2. I would recommend a procuring a commercial gear box that is prequalified. Regards, Michael Shipley
