Gravity
Conveyors
|
|
Gravity
systems have the following advantages:-
Affordable
- Reliable - Durable
- Modular
All
gravity conveyors are constructed from a number of components,
ie, a drilled frame (usually an angle or channel
section), rollers (complete with swaged or flanged
bearings), shafts to mount the rollers and bearings
(can be drilled, hexagon, spring loaded, stubbed or threaded).
Gravity
systems are used in such instances as conveying cardboard
boxes, plastic totes etc. for either, simply transporting
from a to b, or for use in Kanban scenarios. As the title
states gravity means just that, using the force of gravity
to move products. There is no power, hence it is simple
and extremely cost effective. You can either free wheel
the products manually (horizontally) or include a
slight decline to allow a fall over a certain distance.
Because
gravity conveyors are extremely modular they can be utilised
in many ways. They can form a crucial role when linked to
the end of a powered system, for such purposes as packing
and accumulation, or they can actually form a full production
line, such as PC Assembly, Bedding, Industrial Batteries,
General Packing etc.
Standard
Dimensions:- Diameters range from 25mm (light duty -
approximately 10kgs per roller) to 75mm (heavy duty - approximately
600kgs per roller); Lengths are infinite, ie, we can manufacture
a 500mm stand alone section or a series of 3000mm lengths
to achieve the finished length. Widths are usually in increments
of 50mm, ie, 150mm, 200mm, 250mm etc.
Finishes:-
The standard finish to gravity tracks is mild steel self
colour rollers & painted frames; Optional finishes are
1) Bright Zinc Plated, 2) Stainless Steel, and 3) Plastic

The
main component in any gravity system is the roller (see
our accessories/roller section)
these can be supplied in a variety of forms to suit the
application, e.g. mild steel, stainless steel or plastic
- straight, tapered or split parallel for bends. Gravity
systems also come in various forms such as fixed horizontal/decline
tracks, free standing or flexible/extendable tracks. Because
of the flexibility of gravity systems, the client can form
their own custom built working environment.
Mobility
also offer a standard range of light duty gravity conveyors
utilising small diameter plastic or stainless steel rollers
within aluminium or stainless steel channel frames - predominantly
used in the food and packaging industries - where small,
light products can be conveyed in a speedy manner - Please

As
well as traditional gravity roller conveyors, we also
offer our range of versatile systems (illustrated
below) - Firstly there is the telescopic gravity
system, ie, the sections slide under each other.
Alternatively, there is the more adaptable, and more
widely used, gravityflex conveyor, which can
be extended or retracted to suit the required length
(please see configuration table below), and also can
be manipulated to form curves and bends. All projects
are individual, therefore you supply us with information
such as:- a description of the product (weights and
dimensions) and production environment, and we will
tailor the most suitable set of components to create
the most effective scheme.
