Jan 11, 2018 · OSHA 1910.179(b)(6)(i) Overhead and Gantry Cranes states that, “a minimum clearance of 3” overhead and 2” laterally shall be provided and maintained between crane and obstructions in conformity with Crane Manufacturers of America, Inc., Specification No. 61.”

1910.179 – Overhead and gantry cranes. | Occupational

Minimum clearance of 3 inches overhead and 2 inches laterally shall be provided and maintained between crane and obstructions in conformity with Crane Manufacturers Association of America, Inc., Specification No. 61, which is incorporated by reference as specified in §1910.6 (formerly the Electric Overhead Crane Institute, Inc).

CLEARANCE: The minimum distance from any part of the crane to the point of nearest obstruction. COLLECTORS, CURRENT: Contacting devices for collecting current from runway or bridge conductors. CONDUCTORS, BRIDGE: The electrical conductors located along the bridge structure of a crane that transmit control signals and power to the trolley(s).

GIRDER: The principle horizontal beam of the crane bridge which supports the trolley and is supported by the end trucks. HOIST: A machinery unit that is used for lifting and lowering a load. HOLDING BRAKE: A brake that automatically prevents motion when power is off.The minimum horizontal distance between the center of the runway rail and the hook.

Boom (Overhead Crane): The minimum horizontal distance between the center of the runway rail and the hook. Hook Height: Supporting Structure (Jib Crane): For a free standing jib crane the supporting structure is the foundation which the crane is bolted to or implanted in. For a wall bracket or wall cantilever jib crane, the supporting

Apr 06, 2001 · Further, this standard requires that the two inch clearance be maintained ( "be provided and maintained between crane and obstructions" [29 CFR 1910.179(b)(6)(i)]). OSHA considers the two inch clearance requirement for 29 CFR 1910.179(b)(6)(i) to be a minimum distance.

Crane Terminology – Overhead Bridge Crane Manufacturers

GAGE–- Horizontal distance between the centerlines of the rails that support the trolley on a double girder bridge. GANTRY CRANE – A crane similar to an overhead crane except that the bridge for carrying the trolley or trolleys is rigidly supported on two or more legs running on fixed rails or other runway.

Welded flat bars shall be used as rails for light-duty cranes with a small capacity (i.e. up to 15 ton). 1.1.1 STEEL BAR Flat bar shall be made out of non-alloy structural steel according to EN 10025-2; minimum yield stress shall be 250 N/mm2. Length of each portion shall be chosen in order to minimize the number of junctions. 1.1.2 WELDING

Crane beam design: Called often also a bridge crane, an overhead crane consists of parallel runways with a traveling bridge spanning the gap.The crane’s lifting component, known as the hoist, travels along the bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane.

Overhead crane configuration such that the crane end truck wheels ride on the bottom flange of the runway beam. BRIDGE GIRDER (CRANE GIRDER)/ ANSI MH 27.1 Crane member on which carriers or trolleys travel, horizontally mounted between and supported by the end trucks.

Overhead Crane H beam and crane structure . Which do you prefer, crane I beam or H beam? Generally, crane I beam’s cross section can bear direct pressure and good resistance to pull, but the flange of cross-sectional dimensions is so narrow that it is not torsional. Crane H beam is opposite, so both

CLEARANCE: The minimum distance from any part of the crane to the point of nearest obstruction. COLLECTORS, CURRENT: Contacting devices for collecting current from runway or bridge conductors. CONDUCTORS, BRIDGE: The electrical conductors located along the bridge structure of a crane that transmit control signals and power to the trolley(s).

A type of crane or monorail suspension method used to sup­port tracks from an overhead structure and fastened to the structure by means of pressure rather than welding or direct bolting. Clearance: Minimum distance from the physical boundaries of a crane to the nearest obstruction.

OSHA’s minimum line clearance determines only the closest distance that any equipment or material can get to an overhead power line. It does not determine the safe working clearance distance. The safe working clearance distance is determined by adding a crane’s furthest reach, including the extension of any load, to the line clearance distance.

As an example, a runway system can be designed to support a 10-ton crane along with two 5-ton cranes. Depending on the runway design, there may or may not be restrictions to the allowable distance between the loaded cranes.

Crane and Derrick Safety I – Power Line Safety

ALWAYS, when using crane and/or equipment near energized power lines of 50,000 volts (50kV) or more, make sure the minimum distance between the lines and any part of the crane is 10 feet plus 4 inches for each 10kV more than 50kV.

The design of mill buildings in general, and crane runway structures in particular, has been neglected in the literature. Considering the large annual capital investment committed to this type of structure, very little attention has been paid to methods of designing, detailing, fabricating and erecting these structures…
