boom- or deck-mounted, the clamshell tagline reel shall be boom-mounted, and all
the front end and hoisting operations shall be satisfactorily accomplished
without the removal of either. Those special tools that are uniqaue to the crane
and that are required for normal operation shall be furnished.
3.2 First article. When specified (see 6.2), the manufacuter shall furnish
a crane for first article inspection and approval (see 4.3 and 6.3).
3.3 Material. Materials used shall be free from defects which would
adversely affect the performance or maintainability of individual components or
of the overall assembly. Materials not specified herein shall be of the same
quality used for the intended purpose in commercial practice. Unless otherwise
specified herein, all equipment, material, and articles incorporated in the work
covered by this specification are to be new and fabricated using materials
produced from recovered materials to the masimum extent possible without
jeopardizing the intended use. The term "recovered materials" means materials
which have been collected or recovered from solid waste and reprocessed to
become a source of raw materials, as opposed to virgin raw materials. None of
the above shall be interpreted to mean that the use of used or rebuilt products
is allowed under this specification unless otherwise specified.
3.4 Standard commercial Product. The crane shall, as a minimum, be in
accordance with the requirements of this specification and shall be the
manufacturer's standard commercial product with any added features needed to
comply with the requirements. Additional or better features which are not
specifically prohibited by this specification but which are a part of the
manufacturer's standard commercial product shall be included in the crane being
furnished. Standard commercial product is a product which has been sold or is
currently being offered for sale on the commercial market through advertisements
or manufacturer's catalogs or brochures, and represents the latest production
model.
3.5 Performance. The crane shall be capable of performing operational
functions independently and simultaneously, including hoisting, swinging,
booming, and traveling. The crane shall be capable of traveling over rough
ground under adverse or severe conditions as may be encountered in normal
commercial operations. When specified for LST-loading (see 6.2), cranes with
basic butt section securely fastened in the boom rack and with the upper boom
section removed shall be capable of being stowed aboard an LST with ramp in
fully lowered position as indicated in figure 1. The crane design will allow
for convenient disassembly into major components for rail, highway, and water
transportation.
3.5.1 Lifting capacitv. The crane shall have rated lifting capacities of
not less than the loads specified (see 6.2), at the radii specified (see 6.2),
with the boom length specified (see 6.2), with or without outriggers set as
specified (see 6.2) The rated lifting capacties, without outriggers, shall be
not less than 75 percent of the tipping loads; the rated lifting capacities,
with outriggers, shall be not less than 85 percent of the tipping loads; and
shall be within the family of lifting curves of the manfacturer's published
