Dear Mr. Hess:
The following information is in response to your letter of March 18, 1991. In your letter, you reference 29 CFR 1918.45 (f)(1)(ii). We realize you were actually referring to the Marine Terminal Standard 29 CFR 1917.45(f)(1)(ii). 29 CFR 1917.45(f)(1)(ii) states: "After October 3, 1984, overhead bridge and container gantry crane operating control levers shall be self centering so that they will automatically move to the "off" position when the operator releases the control."
This topic is further clarified in the preamble to the standard. The summary and explanation of the standard states: "Paragraph (f)(1)(ii), as proposed, required self-centering controls on all cranes and derricks (46 FR 4235). Interested parties (Exs. 93-7, 93-58, 93-61, 93-70, and 93-74) clearly expressed support for a modification of this provision. The record establishes the infeasibility of self-centering controls on many types of cranes and derricks. Some cranes such as whirley cranes would be extremely difficult, if not impossible, to operate with the additional installation of control levers for self-centering devices. Also, this requirement would not allow multidimensional moves by mobile cranes. As a consequence, self-centering controls will be required on overhead bridge and container handling gantry cranes only. This requirement is effective one year after the effective date of this rule to allow owners and operators a reasonable amount of time to modify existing equipment, if necessary." The final rule was effective October 3, 1983.
It is clear that under current OSHA Regulations 29 CFR 1917.45(f)(1)(ii) only applies to overhead bridge and container handling gantry cranes.
