- Description
- The purpose of this amendment is to add requirements for lifting of equipment and requirements for rigging and sketch. REQUIREMENTS FOR LIFTING OF EQUIPMENT 1. The equipment shall be outfitted with suitable attachments for overhead lifting. 1.1 For multiple point lifts each lifting attachment shall be capable of supporting one half the gross weight of the equipment with a design factor of five to one based on ultimate strength. For single point lifts the lifting attachment shall be capable of supporting the gross weight of the equipment with a design factor of five to one based on ultimate strength. 1.2 For multiple point lifts each lifting attachment shall be designed to accept a standard anchor shackle (Federal Specification RR-C-271D, type IVA) which is capable of supporting one half the gross weight of the equipment. For single point lifts the lifting attachment shall be designed to accept a standard anchor shackle (Federal Specification RR-C-271D, type IVA) which is capable of supporting the gross weight of the equipment. 1.3 Design of the lifting attachments shall be such that the attachments and shackles are not side loaded more than 10 degrees out of the plane. Lifting attachments shall be located such that the lifting slings do not contact the equipment, or alternatively a spreader beam certified to NAVFAC P-307 shall be provided. Whenever practical, the lifting attachments shall be located above the center of gravity, and such that the lifting slings do not contact the equipment housings. 1.4 Each lifting attachment shall be conspicuously marked in a contrasting color "Lift Here". Letters shall have a minimum height of 1". 2. The equipment shall be marked in a prominent location with the gross weight. Sand hoppers, tubes, or other containers that may contain material shall be marked with the empty and full weight (or alternatively the empty weight and working load limit). Marking shall be upper case letters of a contrasting color, with a minimum height of 1". Marking shall include the units (i.e. "pounds", "long tons", etc.). 3. The equipment shall be provided with a lifting sketch / rigging diagram that meets the requirements of enclosure (1). 3.1 The lifting sketch shall detail any specific requirements and / or configurations that must be met prior to lifting (i.e. "engage swing lock", "Tilt mast back fully",, "Rotate lifting basket over side", "Utilize 10' minimum length slings", "Spreader beam required". etc.). 3.2 The lifting sketch shall include the location of the center of gravity of the equipment (Full fuel, hydraulic tanks, etc.), equipment model and manufacturer, and gross weight. 3.3 A copy of the lifting sketch shall be permanently posted on the equipment, and a copy shall be forwarded to Code 714 (396-3345, 3346). 4. If specialized handling gear other than shackles, standard slings, or chainfalls (i.e. spreader beams, special lift rigs, etc.) is required, the contractor shall furnish it. This handling gear shall be provided certified in accordance with NAVFAC P-307, with written documentation of proof testing. Rigging Sketch Requirements 5. Rigging sketches, as a minimum, shall identify the following: 5.1 The weight of the load. 5.2 The location of the center of gravity. 5.3 The minimum crane capacity. 5.4 The minimum capacity / length of slings. 5.5 The minimum capacity of other standard rigging gear. 5.6 The attachment (lifting) points for the load. 5.6.1 The attachment points for multiple leg lifts shall be sized such that each attachment point can support half the load's weight at the anticipated lift angle. 5.6.2 The attachment point for single leg lifts shall be sized such that the attachment point can support the entire load's weight. 5.7 Limitations on allowable orientations for any parts making up the lifting assembly. 5.8 For single leg vertical lifts using twisted rope (wire or synthetic), two parallel ropes each capable of supporting the entire load alone shall be required unless a method is used to prevent unlaying the rope. 5.9 A minimum D/d ratio of one shall be required where wire rope slings pass over any object, or in the eyes of wire rope slings. A minimum D/d ratio of two shall be required where synthetic rope slings pass over any object, or in the eyes of synthetic rope slings. 5.9.1 "D" represents the diameter of the object the sling passes over. 5.9.2 "d" represents the diameter of the sling. 5.9.3 Table 14-3 of NAVFAC P-307 lists efficiency factors at various D/d ratios. 5.10 Components in each handling assembly shall be sized based on the worst case distribution of loads. 5.10.1 When making a two, three, or four point lift, the handling gear shall be sized so that two legs can support the load without exceeding the safe working load (SWL) at the lift angle expected, unless an equalizing method is used. 5.11 When non-standard gear is required (i.e. round stock lifting bars) written instructions shall be provided that ensure: 5.11.1 The proper material is being used. 5.11.2 The item is certified IAW NAVFAC P-307. 5.11.3 Any special requirements or dimensions are followed to ensure that engineering assumptions are met (i.e. eccentricity of the bearing points). NOTE: The response time is 3:00 PM on 9-22-06.
