hinged collar provides up to 70 % weight
reduction,” a company spokesperson
explains. The Crosby Easy-Loc will be
standard on 125 tonne through 300 tonne
Crosby G-2160 wide body shackles and
G-2140 alloy shackles.
Also from Crosby is the G-2170
grommet shackle series. “The series is
intended for those lifting applications
that require high capacity with limited or
tight headroom, such as chemical plants,
refineries, interstate highway construction
and offshore derrick barge cranes,” a
spokesperson explains. “The grommet
shackle provides a bearing surface that is
at least five times that of a round shackle
Where multi-point lifts are concerned,
the tolerance on sling lengths can be an
important issue, as a spokesperson from
Modulift explains, “It can be difficult to
manufacture slings to an exact length, which
can result in uneven forces passing through
the slings which, at high weights, can make
a huge difference.” To overcome this issue
end users can use a cascading spreader
system and certain rigging arrangements to
counter this problem. “In a rig of cascading
spreaders each spreader will be able to tilt
and adjust to help spread the sling loads
evenly,” a Modulift spokesperson adds,
“By doing this the forces are also spread
throughout the load being lifted in a much
more effective way.”
MULTI-LIFT LOADS
the manufacturer explains. “The four
CMOD corner units bolt to struts to make
a square or rectangular frame as desired.
Using a modular system means that the
frames can be reused at different spans
without the need for a new spreader frame
every time.”
“The system works due to a corner
plate, which connects a shackle from
the bow of the plate to the bow of the
shackle,” a company spokesperson adds,
“This allows the shackle to rotate to any
angle and eliminates shackle twisting.”
The system works in areas where there
is limited headroom and, in addition,
the corner plate removes the need for a
rotating lug. The range goes up to 16 m
and has a 100 tonne capacity.
Stable and secure
In line with customer demand for
products that are easy to use and
transport, manufacturer of handling and
rigging accessories, The Crosby Group,
has introduced the new Crosby Easy-Loc
Bolt Securement System.
“The system uses a hinged split collar
assembly instead of a threaded bolt, nut
and cotter pin. When compared to the
nuts used with the traditional system, the
