OSHA Instruction STD 1-15.2 October 30, 1978

September 8, 1975



Subject: 29 CFR 1910.265 (d)(1)(ii)(b) Unloading Equipment and Facilities; Hydraulically Operated Log Handling Machines

1. Purpose.

To clarify the requirement that all lifting cylinders of hydraulically operated log handling machines be equipped with a positive device to prevent the uncontrolled lowering of the load or forks in case of a failure in the hydraulic system.

2. Directive Affected


3. Background

a. 29 CFR 1910.265(d)(1)(ii)(b) requires that lifting cylinders of all hydraulically operated log handling machines shall be equipped with a positive device. A number of comments have been received pointing out the difficulties encountered applying this requirement to the mobile lift-type log handling equipment. An investigation by the Seattle Regional Office revealed that an additional hazard may be created in the operation of mobile lift-type log handling equipment when equipped with this device.



OSHA Instruction STD 1-15.2 October 30, 1978

The Office of Standards Development plan to modify 29 CFR 1910.265(d)(1)(ii)(b) to render it applicable only to the boom lifting cylinders of all hydraulically operated crane type log handling machines in which the load is lifted by wire rope. When the new rule is promulgated mobile-type log handling machines will no longer fall within the scope of this standard.

4. Action

"Any citation issued concerning the lack of positive device for the controlled lowering of the load on a mobile lift-type log handling machine shall be de minimis, when there is no recognized employee exposure to load hazards."

5. Effective Date

This instruction is effective upon receipt and will remain in effect until canceled or superseded by the modified standard.
