Within the general scope defined in Section I of the Introduction, B30.l applies to general purpose, portable jacks of the following categories: hand- or power-operated hydraulic jacks, mechanical ratchet jacks, and hand- or power-operated mechanical screw jacks.
Jacks designed for automotive service, trip-lowered jacks. and those that are an integral part of other equipment are not included in the scope of this Standard. Devices designed for static support rather than lifting are not included.
1-0.1.1 IlLustrations
Figures 1 through 7, on the pages that follow, show typical jacks covered by this Standard. They are not intended to be all inclusive.
SECTION 1-0.2: DEFINITiONS
appoinfrd: assigned specific responsibilities by the employer or the employer’s representative.
authorized service center: an independent senrice facility designated by the manufacturer to repair and test jacks of their manufacture.
controlled conditions: where the jack is evenly supported on a solid foundation, operating a gravity load only, protected against wind and other external forces such as shock loads or vibrations, and at an ambient temperature range of —20°F to I4OGF (—29°C to 60°C).
control parts: parts which the operator must manipulate in extending or retracting the jack.
designated person: a person selected or assigned by the employer or the employer’s representative as being competent to perform specific duties.
extender: a device that increases the jack’s closed length. jack: a portable hand- or power-operated mechanism with a base and load point designed for controlled linear movement.
jack, double-acting hdrauIic: a jack that is extended and retracted under hydraulic pressure.
The inspection dassifications in this Section are minimum requirements and should he augmented when experience from operating conditions so indicates, (See Table 1.)
1-2.1.1 Inspection Classification
(a) Initial Inspection. Prior to initial use, all new, altered, modified, or repaired jacks shall be visually inspected by the user to verily compliance with the applicable provisions of this volume.
(b) Inspection procedure for jacks in regular service is divided into two general classifications based upon the intervals at which inspection should be performed. The intervals in turn are dependent upon the nature of the critical components of the jack and the degree of wear, deterioration, or exposure to severe service. The two general classifications are herein designated asfrequent and periodic, with respective intervals between inspections as defined below.
(1) Frequent inspection. This consists of visual examinations by the operator or other designated personnel with records not required.
(a) normal service: monthly
(b) severe service: daily to weekly
(c) infrequent service: as recommended by a qualified person before and after each occurrence
(2) Periodic inspection. This consists of visual inspection by an appointed person who makes records of apparent external conditions to provide the basis for a continuing evaluation. An external coded mark on the jack is an acceptable identification in lieu of records.
(a) normal service: equipment in place — yearly (b) severe service: as in normal service, unless
external conditions indicate that disassembly should be done to permit detailed inspection — quarterly
(c) infrequent service: as recommended by a qualified person before the first such occurrence and as directed by the qualified person for any subsequent occurrences
1-2.1.2 Frequent Inspection
Items such as those listed in paras. 1-2.1.2 (a) through (j) shall be inspected at intervals as defined in para. I2.1.1(b)(1). Frequent inspection shall include observations during operation. A designated person shall determine if conditions found during the inspection.
