SWR SIMPLIFIES WASTE COLLECTION WITH NEW
CRANES
SWR has enhanced its ability to handle a wide range of waste
items from customers premises by specifying a Penny Hydraulics
Swing Lift V20 crane on each of its two new collection vehicles.
The cranes were selected for their performance and simplicity
and will be used to handle items including IBC dumpy bags and
other bulky loads on and off the vehicles as part of a well-organised
and highly efficient operation.
It is a very simple crane with the weight capacity we
need and it fits the bill, says Mark Hammett, Fleet and
Compliance Manager at SWR. Penny Hydraulics worked with
us to devise a solution and we were very comfortable working
with a company with a forté in this area.
SWR provides waste and recycling services to customers in the
automotive, industrial and general business sectors. The company
operates from depots throughout the UK providing nationwide
coverage and offers a bespoke one-stop-shop solution enabling
customers to match services to their unique requirements. Motor
dealerships and bodyshops form a major part of SWRs customer
base and the range of waste that has to be collected regularly
from their premises is varied. For example, paper, cardboard
and plastic packaging material is stored in IBC dumpy bags or
baled on site prior to collection. Meanwhile metal items such
as body panels, brake discs and general scrap are handled in
stillages.
The company is constantly reviewing its operations to identify
improvements and as the business grew it recognised the advantages
of using vehicles specially configured for efficient handling,
loading and transportation of waste. Towards the end of 2008
the company decided to purchase two new vehicles to operate
from its busiest depots. After considering a number of options
SWR came up with a concept based around an 18000kg Renault vehicle
with rigid body on the offside and curtains on the nearside.
The company also modified the way it collects paper, card and
plastics. This was previously handled in wheelie bins but these
are now lined with IBC dumpy bags which are removed and loaded
onto the vehicle. This saves overall weight, makes waste easier
to handle and offers the prospect of a better loading density.
The front two thirds of the vehicle is used for the IBC dumpy
bags and other items while the rear section is for the stillages,
which are loaded by hand pallet truck using the vehicles
tail lift. The switch from moving wheelie bins meant that an
alternative method of handling was required for the bags. A
crane was the obvious option but most of the products available
had a maximum capacity that was well above the requirement and
this made them too expensive.
We didnt need a really big crane but our bodybuilder
mentioned Penny Hydraulics and away we went, says Mark
Hammett. The model they suggested was the Swing Lift V20
and although we looked at competitor products this was quickly
identified as being the most suitable.
The Swing Lift V20 is the largest crane in the extensive Penny
Hydraulics range. It has a maximum load capacity ranging from
2000kg at 1.4m extension to 720kg when the boom is fully extended
to 3.5m. This performance allows SWR to handle IBC dumpy bags,
paper bales and other loads in all configurations of the crane.
In general use the V20 is mounted at the front of the loadspace
and can handle items into any position in the front two thirds
of the vehicle. For added flexibility Penny Hydraulics supplied
an alternative mounting socket that has been fitted towards
the centre of the nearside loadspace. The crane can be repositioned
whenever required so that it can handle items to any point on
the vehicle. This is achieved by simply unplugging the power
supply, transferring the crane to the second socket and reconnecting
the power to the alternative supply point. The crane is completely
self contained, with its hydraulic reservoir and motor located
within the main body, so there are no complicated or potentially
messy connections to worry about. Like other cranes in the Penny
Hydraulics range the V20 folds down to the king post when not
in use to maximise the available floor and load space.
The simplicity of the crane and the small amount of space
it takes on the vehicle make it ideal for this type of work,
says Mark Hammett.
One of the big advantages of the layout of the new vehicles
is load handling and storage efficiency. SWR estimates that
it can now store up to 15 IBC dumpy bags in the same space on
the vehicle as four wheelie bins. This is possible because the
bags pack more closely together, only take up as much height
as the waste they contain and can be stacked up to four high
using the crane. To ensure the crane can raise the bags to the
required height the vehicles have a fully-retractable roof permitting
the boom to extend safely without restriction.
After assessing SWRs operational requirement Penny Hydraulics
devised and constructed a special spreader attachment for the
crane that allows the bags to be handled safely even when the
straps cannot be drawn together, a common occurrence in waste
collection. The spreader is a simple cross that connects to
the cranes hook and has safety catches at the end of each
arm to lock the bag straps into place for security during lifting.
It is typically used in conjunction with a weighing device that
allows SWR to measure the amount of waste collected from each
customer so that it can provide audits and charge for services
accordingly. The crane was supplied with a remote wander lead
controller that allows the operator to stand in a safe position
well clear of the working area and vehicle while loading and
unloading takes place.
The new sack collection system is more flexible and efficient,
says Mark Hammett. It allows us to provide a better service
to customers and reduces the number of vehicle movements, permitting
us to visit more customer sites per journey before the vehicle
is full to capacity.
It is really satisfying seeing something come to life
that was just an idea on paper only a few months ago.
