Conveyor frames
Lattice conveyors with lengths
of up to 10 metres are
manufactured complete in one
section. Lattice conveyors
longer than 10 metres are
manufactured in sections that
are put together on site using
connection studs. Lattice
conveyors are manufactured from
rectangular tubing. Channel
frames and steel profile frames
are manufactured as an
alternative to lattice frames.
Drive
section
Drive sections are manufactured
as standard in a steel
construction and prepared for
roof and front dust hood with
inspection hatches as required.
The discharge chute, which is
usually customer specific, is
also connected here.
Power is transmitted to the
drive pulley through a shaft
mounted helical gearbox and
V-belts, as well as a direct
coupled, completely sealed,
electric motor, dimensioned to
start with a load of a given
capacity. The v-belt pulleys are
mounted with clamp bushings.
Power transmission is available
both in constructions with
single drive and double drive.
As an alternative to standard
drive, options with electric
pulley or geared motor can also
be supplied.
As standard, the drive pulley is
covered with a frictional
material of patterned rubber.
Other options that can be
supplied are frictional material
of ceramic covering, various
qualities of rubber, or screwed
rubber bars. Any snub pulleys
that are fitted against the
belt’s goods side are rubber
coated.
Tension section
The belt is tensioned using jack
screws, or alternatively a
counterweight as standard. For
conveyor length up to 50 metres
jackscrews are normally used.
The jack screws are usually
positioned at the tail pulley.
Counterweight tensioning
produces a more even belt
tension and is automatically
self adjusting. In those cases
where there is no room for a
tension device by the tail
pulley, a counterweight
tensioning in a loop can be used.
As an alternative, hydraulic or
constant-motor tensioning can be
used.
Feed
hopper
Feed hopper type N is used for
conveyors that are not enclosed
or partly enclosed. In the
standard construction it is two
metres long and has a 45°
incline on the sides. The
thickness of the sheet metal is
4 or 8 mm. The hopper can
subsequently be furnished with
an anti-wear covering of rubber
or sheet metal to increase wear
resistance. For totally enclosed
conveyors a feed hopper with
double rubber edges against the
belt is recommended.
Idler
sets
The idler sets are manufactured
in a sunken construction in
order to give the conveyors as
low a centre of gravity as
possible to increase stability
as well as to reduce the loading
height. The idler sets are
hot-dip galvanized and have an
inclination in the transport
direction which produces a belt
centring effect. For belt width
500 and wider the idler sets are
divided into three parts with a
30° troughing angle. From belt
width 650, the conveyor can also
be supplied with three part
idler sets and a 45° troughing
angle.
Idlers
The idlers are manufactured from
steel pipe and have
greased-for-life bearings which
are effectively sealed.
Standardised idler diameters can
be offered. Of these, in most
cases the 108-idler is used,
however, for especially
demanding conditions larger
idlers can be supplied. The
impact and return idlers are
available in the same diameter
series as the other idlers,
however, they are fitted with
rubber rings. The rubber rings
on the impact idlers have a
dampening function. Return
idlers are supplied as standard
with rubber rings. As an
alternative, return idlers can
be supplied steel cased or
rubber coated. To counteract
lateral belt movement, guide
rollers are used, or
alternatively belt steering
equipment.
Conveyor Belts
In our conveyors we use belts
with a high resistance to wear
and damage from impacts and
rips, with a minimum of stretch
to ensure the high level of
quality that our customers
demand. Material, application
and loading conditions are
decisive when selecting type of
belt. Increased material
requirements produce accordingly
higher demands on the belt’s
characteristics. In these cases
the option is available to use
additionally reinforced,
patterned, oil-, grease-,
chemical-, terpene- or
heat-resistant belts, as well as
chevron belts or flexowell belts.
Impact
mat
Is made of thick, reinforced
PVC-fabric and positioned under
the conveyor belt at the loading
station, where the impact mat
replaces the impact idler sets.
The impact mat is recommended
where material in large and
heavy pieces is loaded on the
conveyor.
Impact cradle
Is used for especially demanding
loads of material which is in
large and heavy pieces. The
impact cradle is an extremely
robust construction with impact
bars. The assembly system
provides a fast and service
friendly installation.
Walkways,
platforms and stairways
Walkways are manufactured in two
standard constructions using
respectively floor grating and
expanded
metal covering. The brackets for
the walkways are screwed on
under the conveyor frame.
Walkways in SSG construction can
be supplied. Stairs and ladders
are manufactured according to
local conditions.
Service platforms are usually
used at drive stations and are
available in two standard
constructions, single-sided for
single drive and double-sided
for double-drive with the
alternative of a catwalk over
the belt or around the drive
station. The service platforms
are wider than the walkways in
order to leave room for
servicing of the drive station.
The platforms are screwed into
the conveyor frame.
The conveyor bridge are
manufactured in a lattice
construction. The exterior of
roof and sides is fitted with
sheet metal with a corrugated
finish. The floor consists of
sheet metal, floor grating or
wood, and is supplied with
ant-skid protection where the
incline makes it necessary.
Alternatively, conveyor bridges
can also be supplied in an open,
covered or insulated
construction. Light apertures,
windows, doors, gates, lighting,
sprinklers, smoke outlets,
drainage is supplied according
to the customer’s requirements. |
