A reel solution for safer handling February 1st 2008 Adding to its selection of overhead hoist mounted reel handling systems, the new range
of reel turner attachments for both pedestrian stacker and counterbalanced fork trucks
from the Reel and Shaft Handling Company allows the reel to be lifted in the core,
preventing damage to the outer layers of the material
Following an injury caused by a reel
dropping when an operator tried to
turn it manually, a leading UK
packaging extrusion and printing company
commissioned The Reel and Shaft Handling
Company, (RSHC), to design and
manufacture five reel turners, capable of
handling up to 300kg reels by gripping in
the core.
The RSHC first made a prototype by
taking its existing hoist based Reel Turner
Mk2 system, originally designed for
handling reels up to 125kg, and fitted it to
a prototype fork pocket support. They
trialled this with great success at the
customers factory proving the system
would work. They then went about
designing two different versions of the new
Reel Lifter Mk3, four of which were to be
mounted on the fork carriages of Armanni
Speedylight Pedestrian Stacker trucks, the
fifth was to be mounted onto fork pockets,
so that it could be used by any one of the
fork trucks operating in the warehouse.
The design process required several key
features to be integrated into both models,
which produced some innovative solutions.
"There are two key features that should
be built into any good reel turner," explains
md Stephen Weston.
"The first is that it has to grip the reel
securely, absolutely 100% of the times it
lifts. In our case we were designing the
Reel Turner Mk3 to pick up in the core of
the reel. This meant that we had to use a
fail-safe method of gripping the reel with a
spring engaged chuck, which self engaged
as soon as the operator let go of the release
mechanism. The second key feature that
had to be incorporated, was powered
rotation, as it would be pointless to put in a
piece of handling equipment to lift heavy
reels and then ask the operator to struggle
to manually rotate the reels."
The problem of powering the rotation on
the Armanni Pedestrian Stacker truck
mounted models was relatively simple. The
stacker had an integral hydraulic pump
powered by the 24V battery system.
Two versions of the carriage mounted Reel
Turner Mk3 were developed, one using a
powerful hydraulic Rotary actuator to turn
the reels. The other version, (which,
although more expensive, was eventually
chosen by the customer), used a compact
24Vdc electric motor and gearbox to power
the rotation. Both systems required only
minor work to tap into the stacker trucks
electrical or hydraulic
supply and when the Reel
Turner Mk3 is supplied
complete with an
Armanni Pedestrian
stacker, the stacker comes
with plug-in attachments
for both services.
However, the problem
of powering rotation on
the Fork Pocket mounted
Reel Turner Mk3 was
more difficult to
overcome. The fork trucks
in the customers' factory
had different voltage
systems and only a few
were fitted with extra
hydraulics and it was
recognised that future sales could also have
this problem.
The RSHC's designers then developed
five stand alone models, each with a
different means of powering the rotation:
electric powered from the stacker truck,
electric powered from its own on-board
battery, hydraulic powered from the stacker
truck, hydraulically powered from an onboard
hydraulic pump and manually rotated
via a handwheel and gearbox.
Stephen Weston comments, "A key
aspect of all the designs, after safety and
ease of use, resulted from a rapidly growing
number of export enquiries. We therefore
decided to make all versions of the Reel
Turner Mk3 into compact self contained
units that would be easy to ship and retrofit
onto a customer's own stacker, anywhere in
the world. In this way, a stacker truck can
be locally sourced, or an existing stacker
truck used, saving on shipping costs. We
now offer factories having to turn reels, the
opportunity to safely lift and turn heavy
reels by the core, at minimal cost."
The end result was a highly flexible
range of Reel Turner designs, all essentially
doing the same job, but with the options of
being fixed or temporarily mounted and
being electrically, hydraulically, manually, or
even pneumatically powered.
