(iv) Cranes shall not be used for lateral pulling unless expressly authorized by a responsible person who has determined that the stability of the crane is not threatened and that the various parts of the crane are not subject to undue stress. (i) initial inspection. Prior to first use, all new and modified cranes must be inspected to ensure that they comply with the provisions of this section. (i) warning device. Except in the case of ground cranes, a gong or other effective warning signal shall be provided for each crane equipped with a drive mechanism. (iii) Standby cranes shall be inspected at least every six months in accordance with the requirements of point (j)(2) of this Section and point (m)(2) of this Section. (vi) Stamped or compressed fittings shall be fitted in accordance with the recommendations of the cable or crane manufacturer. This is a continuation of our letter of 6. April 1993, a copy of which is attached. This letter provided guidance on the requirements that had to be met before employees could perform work, such as maintaining ceiling lights, platforms or walkways on overhead cranes and gantry cranes. However, the April letter did not provide specific guidance on actual platforms and sidewalks, and the purpose of this letter is to address this issue. The guidelines for platforms and gangways on cranes are as follows: (7) A hot metal handling crane is an overhead crane used for the transport or casting of molten materials. (13) `storage crane` means a long-span gantry normally used for mass storage of material; The beams or trusses of the bridge are rigid or non-rigid supported on one or more legs.
It can have one or more fixed or folding cantilever ends. (4) A cantilevered gantry is a gantry or semi-gantry in which the girders or trusses of the bridge protrude from the crane runway on one or both sides. (e) When other cranes are in service on the same runway, stops or other appropriate equipment shall be provided to avoid disturbing the stationary crane. (21) Bridge is the part of a crane consisting of girders, trucks, end ties, trails and a drive mechanism supporting the trolley(s). (7) Extension lamps. If there is a service socket in the cab or on the deck of cranes with driver`s cab, it shall be a continuous grounded three-pole outlet that shall not exceed 300 volts. (a) Bumpers shall have sufficient energy capacity to stop the crane when moving at a speed of at least 40 per cent of the rated load speed. (57) A stop is a device intended to limit the movement of a cat or crane deck. This device is usually attached to a solid structure and usually has no energy absorption capacity. (ii) The driver`s cab shall be so arranged as to ensure a distance of at least 3 inches from all fixed structures within its possible range of motion. (50) The rated load is the maximum load for which a crane or individual hoist is designed and constructed by the manufacturer and indicated on the nameplate(s) of the equipment.
Thank you for your interest in workplace safety. We hope you find this information useful. OSHA requirements are set by laws, standards, and regulations. Our interpretive letters do not create new or additional requirements, but explain these requirements and how they apply to particular circumstances. This letter represents OSHA`s interpretation of the requirements under discussion. From time to time, letters are affected when the organization updates a standard, a court decision affects a standard, or technological changes affect interpretation. To ensure that you are using the correct information and guidance, please visit the OSHA website at www.osha.gov.

Scenario: An overhead crane is used to handle and manipulate suspended loads. The crane is controlled by an operator (employee). The operator may temporarily or otherwise lose control of his hand due to a diagnosed health condition that prevents the completion of the elevator or the return of the load suspended to the load receiver (floor, pallet, platform, shelf, etc.). During our telephone conversation on May 2, 2013, you explained that at such a departure, you, the operator, would have to leave or abandon the suspended load to find another operator to complete the elevator. (1) Application. This Section applies to overhead cranes and gantry cranes, including half-cranes, cantilevered gantry cranes, wall-mounted cranes, storage cranes and others having the same basic characteristics. These cranes are grouped together because they all have similar trucks and driving characteristics. (iv) The lifting movement of all electric overhead cranes shall be equipped with a drive switch in the direction of lifting.
(b) (2) Existing equipment installed before 31. August 1971 were built and installed for specification? Also, do cranes built before this date and retrofitted later have to comply with the requirements? Existing equipment constructed and installed before August 31, 1971 does not need to meet this specification. Cranes built before that date and retrofitted later are also exempt from this specification; However, these cranes must meet the requirements of 1910.179(b)(3), Amendments. OSHA requirements are defined by laws, standards, and regulations. Our interpretative letters explain these requirements and how they apply to particular circumstances, but they cannot create additional obligations for employers. This letter represents OSHA`s interpretation of the requirements under discussion. Please note that our enforcement guidelines may be affected by changes to OSHA rules. We also update our guidelines from time to time in response to new information.
To stay informed of these developments, you can visit the OSHA website at www.osha.gov. 5. A land-based crane is a crane that is a suspended or non-conductive cable controlled by a ground operator or an independent platform. Thank you for your letter to the Enforcement Programs Directorate (EPD) of the Occupational Safety and Health Administration (OSHA). You have inquired about OSHA`s requirements under 29 CFR Part 1910 – General Industry and 29 CFR Part 1918 Longshoring. (a) The crane to be repaired shall be moved to a location where it least disturbs other cranes and operations in the area; (3) Periodic inspection. Full inspections of the crane shall be carried out at intervals generally defined in paragraph (j)(1)(ii)(b) of this clause, depending on its activity, the severity of maintenance and the environment, or as expressly stated below. Those inspections shall include the requirements set out in point (j)(2) of this Section and, in addition, the following.
Any failure such as those listed shall be carefully assessed and determine whether it poses a safety risk: (i) A crane that has stopped for a period of 1 month or more but less than 6 months shall be inspected in accordance with paragraph (j) 2 of this Section and paragraph (m) point 2 of this Section before it is put into service.
