Double Pillar Drum Lift Description
This double pillar drum lift is designed to lift and tip a pair of 200 Litre Tomato
Puree Drums at a discharge height of 3800mm into a 5000 Litre Stainless Steel Storage
Tank. The double pillar drum lift was constructed from Grade 304 stainless steel
and was designed to be bolted to the floor. Lifting with the double pillar drum
lift is accomplished via chains driven by a motor gearbox mounted at the top of
the one column with a crossover shaft to the other column. To make loading and unloading
of the drums as efficient and easy as possible, the base of the lifting frame is
fitted with gravity rollers. The drums can fed directly off the gravity infeed roller
track into the lifting frame. The drum entrance to the double pillar drum lift is
guarded using a safety light barrier. Once in the lifting frame, the drums are clamped
into the lifting carriage using an electrically interlocked sprung gate. If this
gate is not closed and latched, it will automatically spring open preventing the
double pillar drum lift from operating.
Safety Guard to PD 5304:2005 Safety of Machinery
The safety guard is constructed from 40 x 40 x 3mm stainless steel box section and
both 2mm stainless steel sheet and 3mm wire, 40mm aperture stainless steel weld
mesh to meet the requirements of PD 5304:2005 Safety of Machinery. It encloses the
double pillar drum lift to a height of 4745mm on all four sides with a safety light
barrier guarding the drum entrance. There was also a hinged door at the front of
the double pillar drum lift to allow the operator access to the clamp the drums
into place and to retrieve the empty drums after tipping. The guard door is electrically
and mechanically interlocked preventing the double pillar drum lift from operating
with the door open. In addition, the guard door can only be opened when the lifting
carriage is at the full down position. The double pillar drum lift control system
has provision for a ‘Call for Product’ signal to be connected.
Double Pillar Drum Lift Application Story
This Tomato Puree Handling System was required to handle drums of tomato puree from
a pallet, into a double pillar drum lift and to be lifted and tipped into a storage
tank. The system comprised of four distinct items as follows:-
Powered Roller Conveyor for Pallets of Tomato Puree Drums
This was a 3200mm long section of Powered Roller Conveyor that was loaded with 1200
Kgs Pallets containing 4 drums of Tomato Puree by a fork truck. The pallets were
then indexed via dead man handle control to the outfeed end where the pallet was
unloaded, two drums at a time. The roller track was 1200mm wide across the roller
with a 100mm roller pitch. The whole conveyor was 400mm high and was supplied as
a single length with a braked drive motor, a fork truck barrier and was manufactured
from mild steel with a painted finish.
Drum Transfer System from Pallet Conveyor to Single Drum Gravity Conveyor
The Drum transfer was carried out via a pair of semi automatic drum clamp tongs
suspended from a lifting frame attached to an overhead lifting gear. The pallet
to be unloaded was driven towards the end of the powered roller track and the drum
clamps lowered over the drums with a chain hoist. The drums were clamped securely
and transferred onto a gravity roller track using the powered overhead hoist transfer.
This whole system was a dead man handle operation via a push button control pendant.
Once the first pair of drums were removed from the pallet and moved along the single
lane roller track, the remaining pair of drums were transferred.
Full Drum Gravity Roller Track Infeed Conveyor
This gravity roller track conveyor allowed two drums to be stored in single file
for loading into the double pillar drum lift. It was approximately 1600mm long,
650mm wide and 400mm high off the floor. Each drum was transferred along the roller
track by simply pushing it. The roller track and rollers were manufactured from
304 stainless steel and were mounted on M12 adjustable feet. There were also side
guides to prevent the drums from falling off the roller track. The drum lids and
clamp rings were removed at this position and the bag pulled down over the rim of
Double Pillar Drum Lift
The double pillar drum lift was designed to lift and tip a pair of Tomato Puree
drums into a 5 Tonne Stainless Steel storage vessel. The double pillar drum lift
had a Safe Working Load of 800Kgs and tipped the drums through an angle of 180 degrees
at a height of approximately 3800mm. The double pillar drum lift was constructed
from Grade 304 stainless steel and was bolted to the floor. Lifting with the double
pillar drum lift was accomplished via chains driven by a motor gearbox mounted at
the top of the one column with a crossover shaft to the other column. The inner
front face of the lift and safety guard were fitted with stainless steel sheet to
allow any tomato puree from the bags to be easily washed away.
Having loaded a pair of drums or a single drum, the double pillar drum lift was
operated by pressing the ‘Start’ button. The double pillar drum lift automatically
raised to the full up position where the drums were inverted through 180 degrees.
The double pillar drum lift paused at this position for an adjustable time period
and then returned to the full down position.
Tomato Puree Storage Tank
The Tomato Puree Storage Tank was a 5000 Litre tank manufactured from 3mm Grade
316 Stainless Steel with a 5 Tonne storage capacity. It was 1900mm diameter with
an overall height of 3680mm and stood on three adjustable feet. The top the tank
was fitted with a rectangular hopper through which the drums were tipped as well
as a manhole access and CIP Cleaning System. The hopper was fitted with a pneumatically
operated lid which was interlocked with the double pillar drum lift.
