ASME B30.14-2015 pdf – Side Boom Tractors.
(2) all controls at the manufacturer’s recommended position
(3) starting means rendered inoperative, except when required for repairs
(4) hydraulic oil pressure relieved from all hydraulic circuits before loosening or removing hydraulic components
(5) power plant stopped or disconnected at take-off
(6) boom lowered to the ground, if possible, or otherwise secured against dropping
(7) lower load block lowered to the ground, if possible, or otherwise secured against dropping
(b) “Warning” or “Out of Order” signs shall be placed on the side boom tractor controls.
(c) After adjustments and repairs have been made, the side boom tractor shall not be returned to service until all guards have been reinstalled, safety devices reactivated, maintenance equipment and “Warning” or “Out of Order” signs are removed, and equipment function checks are complete.
14-2.3.3 Adjustments and Repairs
(a) Any hazardous conditions, disclosed by the inspection requirements of Section 14-2.1, shall be corrected before normal operation of the side boom tractor is resumed. Adjustments and repairs shall be done only by designated personnel.
(b) Adjustments shall be maintained to assure correct functioning of components. The following are examples:
(1) all functional operating mechanisms
(2) limit devices
(3) control systems
(4) braking systems
(5) operational aids
(c) Repairs or replacements shall be made as needed. The following are examples:
(1) side boom tractor hooks showing defects described in para. 14-2.1.2(f) and ASME B30.1O shall be taken out of service. Repairs by welding or reshaping are not recommended. Repairs shall be done under supervision by a qualified person and the hook shall be tested to the load requirement of para. 14-2.2.1 before further use.
(2) load attachment chains and rope slings having any of the conditions described in para. 14-2.1.2.
(3) all critical parts that are cracked, broken, bent, or excessively worn.
(d) If repairs of load sustaining members are made by welding, identification of materials shall be made and appropriate welding procedure shall be followed in compliance with original manufacturer’s recommendations. If information is not available from the original manufacturer, the recommendations of a qualified person shall be followed.
14-2.3.4 Lubrication
(a) A lubrication chart should be available on the side boom tractor.
(b) All moving parts of the side boom tractor for which lubrication is specified, including rope and chain, should be regularly lubricated. Lubricating systems should be checked for proper delivery of lubricant. Care should be taken to follow recommendations of the manufacturer as to points and frequency of lubrication, ma intenance of lubricant levels, and types of lubricant to be used. If the manufacturer cannot supply this information a qualified person should be consulted.
(c) Machinery shall be stationary while lubricants are being applied and protection provided as called for in paras. 14-2.3.2(a)(2) through (5), unless equipped for automatic lubrication.
All inspections shall be performed by a designated person. Any deficiencies identified shall be examined and a determination made by a qualified person as to whether they constitute a hazard.
14-2.4.1 Rope Inspection
(a) All running ropes in continuous service shall be visually inspected once each working day. This inspection shall consist of observation of all rope in service during the day’s operation. An inspection of all ropes shall be made at least monthly and a dated report of rope condition kept on file. Sections of rope that are normally hidden during visual and maintenance inspection, such as parts passing over sheaves, should be given close inspection as these are points most likely to fail. Any deterioration resulting in appreciable loss of original strength, such as the following, shall be noted and determination made as to whether further use of the rope would constitute a hazard:
(1) reduction of rope diameter below nominal diameter due to loss of core support, internal or external corrosion, or wear of outside wires
(2) a number of broken outside wires and the degree of distribution or concentration of such broken wires
(3) worn outside rires
(4) corroded or broken wires at end connections
(5) corroded, cracked, bent, worn, or improperly applied end connections
(6) kinking, crushing, cutting, or unstranding
(b) Heavy wear or broken wires may occur in sections in contact with equalizer sheaves or other sheaves where rope travel is limited, or with saddles. Care shall be taken to inspect ropes at these locations.
