Now That's a Skip!
Click on the thumbnails to enlarge
Agora Services fabricated this skip to the clients design. The side and
back plates are 10mm thick, whilst the base and front panel are 12.5mm thick.
The lifting lugs are 40mm thick, with the rear pivot lug having an EN8 wear bush
stitch welded in place. The capacity of the skip is 7.4 cubic metres, the
overall weight of it empty is approximately 2.4 tonnes.
The customer has told us that they test loaded it with 30 tonnes of steel,
the designed working load being for 20 tonnes of concrete. The skip will
be used for tunnelling.
Agora also fabricated a number of heavy jacking brackets/frames for the same
customer, approximately 12 tonnes in total, using a 305 x 305 x 198kg UC.
Recycled Glass Silos
Recycled glass silos designed and fabricated by Agora Services for RDT of
Australia. These have been installed as part of a new waste recycling
plant at Leyland, Lancashire.
The silos have been designed to hold up to 100 tonnes of waste glass each.
Construction was on the heavy side for silos of their size, being 4.5m diameter
internally, and 7m height from the underside of the flange on the outlet cone to
the top stiffening angle. Due to the abrasive nature of broken glass the
hopper was fabricated from 8mm thick steel plate and the cylinder from 6mm
plate. The overall height including the steelwork being approximately 8.4m
from the base plinths.
Initially RDT had specified a semi welded design, with a paint finish.
Agora suggested a standard fully modular bolted construction, which would have
been more cost effective to fabricate and could be fully galvanised. Concerns
were raised regarding a potential build up of material on ledges in the
hopper, thus a compromise solution was found.
The final design was of a welded hopper, split into three section, two making up
the upper section and a lower cone. These were flanged externally to
prevent ledges from potentially causing hang ups of material and minimise
bridging. The cylinder was agreed to be of a standard bolted construction,
but the panels overlapped on the inside, again to minimise potential ledges that
material could catch. The fastenings used in the cylinder panels being
dome headed silo/tank bolts. Modular cylinder panels and the support
steelwork could then be galvanised. However, the hopper sections were too
large and thus given a hot zinc metal spray finish to the outside surfaces.
As the glass material to be passed through the hoppers would be highly abrasive
it was deemed that any internal coat to the hopper would be very rapidly worn away
and thus unnecessary.
Given that hot metal spraying is an expensive finish, the internal hopper
surface was thus left plain.
This is part of the much larger W2R project at Leyland, building a household
waste recycling plant, to stop the disposal of household waste by landfill.
Items such as glass, metal and plastic are to be separated out for recycling,
the remaining organic materials to be composted. The aim of the local
authority is to eventually have no disposal by landfill, thus being
environmentally friendly.
Garden Metalwork

Agora have recently completed the fabrication of three garden arches and a
garden rail.
The arches have been made from 16mm diameter solid bar, with 10mm diameter
solid tie bars. These have been made to the customers requirements,
measuring 1.2m wide x 2.96m tall with 2.4m above ground. The arch itself
was formed using our initial pinch rolls and the complete structure was fully
welded.
The rail was ordered once the arches had been installed, again this has been
fabricated to the customers requirements. Initially planned as an
interlocking bowtop rail, the customer came up with the idea of an elliptical
arch. This created a very interesting panel. The outer frame is 40 x
6mm flat and the arches are 12mm solid bar. Overall the panel is 2.4m x
0.925m. One end will be screwed to an existing timber post, whilst the
other end will attach to the upright on one of the arches using ubolts.
All in all they are an impressive garden feature and have been an interesting
little project. Talking to the customer they have said the idea came to
them after seeing Victorian ironwork in a large stately garden.
Got That Sinking Feeling!
Agora Services are in the process of fabricating eight heavy duty jacking stands
for a sinking concrete shafts into the ground for tunnelling.
The stands are made of 305 x 305 x 158 Universal Column, and despite their
relatively small plan size, they weigh in at an impressive 1.5 tonne each.
We have so far completed and supplied four of these units, with another four
being completed today ahead of schedule.
The stands are predrilled for the jacking units to bolted into position
onsite, with an additional 21 tonnes of counter balance weights to be placed on
the three horizontal sections.
All joints have been fully welded, 8mm fillets as instructed. To save
on cost the customer supplied most of the column section free issue, having been
used on a previous job, hence the additional holes.
Grade 304 Stainless Steel Ducting
This ducting was fabricated to the customers requirements, with all development
work being done by Agora. The ducting is 250mm inside diameter, straight
sections being made from tube, and the bends being made of plate, developed,
laser cut/profiled, then rolled. The vertical tubes feed product from two
cyclones into the pneumatic conveying line via a small hopper and a venturi.
Due to the poor flowing qualities of the product, there have been several
pneumatic hammers fitted to the ducting, these can be seen on the hopper, the
vertical joggle tubes from the cyclones. As Abitec had found in the past
that this type of hammer can vibrate loose and fall from it's mounting plate, we
also fabricated brackets to hold the body of the hammer. These could then
be bolted using locknuts, thus meaning that they could not fall should they
vibrate loose, making it safer to fit them at height.
As part of the same project Agora made additional hammer plates and brackets,
which we then welded in place on other parts of the plant.
This ducting has been in one year and we understand works perfectly.

Test build of safety grap wire frame
The frame will be site fitted with a grab wire emergency safety shut off system.
Agora have recently completed the sub-contract manufacture and supply of a
waste recycling
conveyor for O Kay Engineering of Market Harborough. The conveyor was
approximately two metres wide and twenty six metres in plan length. It was
supplied built up in three sections, ready for the site installation by O Kay.
The belt is made up of pressed fabricated steel slats, joined with a specially
manufactured chain. The drive unit, shafts and chain were supplied by O
Kay.
The conveyor will be used to feed waste cardboard into a compactor for
recycling.
Removal of Cold Store
Agora Services successfully removed a cold store building for a existing
customer, offering a considerable saving on the costs given by the original
manufacturer for the same job.
The project involved the use of a scissor lift and a cherry picker to gain
safe access for the removal of the roof and wall panels. As the store was
to be scrapped several of the panels had to be cut up during removal. The
structure was a standard cold store, made up of metal clad polystyrene sheets
slotted together and riveted. The store covered four bays of pallet
racking, the racking being seven pallets long and three high. The three
cooler units had already been disconnected and were removed by Agora.
The scrap panels were stacked into skips for the customer to dispose of as
required.
New Loading Bay Canopy complete with ramp and dock leveller.
Agora Services redesigned, fabricated and installed a new loading bay canopy for
Abitec of Northampton. The original design called for the roof of the
canopy to slop toward the existing building with a valley gutter and parapet
wall. This design proved to be too costly, thus was altered to bring the
structure into budget by sloping the roof away from the building, removing need
for valley gutter and removing the parapet.
The initial survey by Agora found that existing structure could not be
connected to as suggested by the architects. Abitec did not want to used
additional external columns, thus special haunched bracket columns were used to
support the roof beams from the existing building. The overall design was
interesting as the structure tapers, meaning that every column and beam is
slightly different, as the beam/column connections are angled both horizontally
and vertically.
The foundations and the ramp were installed by a civil contractor employed by
Abitec, and the dock leveller was installed by Crawfords. Agora carried
out all fabrication/installation of the steelwork, the handrail, the access
stairs to dock leveller, the cladding, the roofing and the guttering.
Previous to the installation of the new ramp lorries had been loaded with a
forklift on a external mobile steel ramp. We have it on good authority
that the forklift drivers refused to use the mobile ramp as soon as new loading
bay was operational!
